DEFINING WHAT TO REGULATE: SILICA AND THE PROBLEM OF REGULATORY CATEGORIZATION INTRODUCTION Firms and doctors involved in silicosis suits are facing grand jury investigations in New York, and a federal judge in Texas has suggested fraud may be involved in some of the tens of thousands of silicosis claims pending in her court, charging that one firm had attempted "to inflate the number of Plaintiffs and claims in order to overwhelm the Defendants and the judicial system."[1] Doctors involved in diagnosing silicosis claimants are pleading the Fifth Amendment right against selfincrimination rather than electing to testify before Congress about their roles in the lawsuits.[2] At the same time, silica dust regulation is on the agenda of regulatory agencies around the world. The United States Occupational Safety and Health Administration (OSHA) and regulators in other countries[3] are considering issuing new standards for silica dust, spurred on by the International Labor Organization and the World Health Organization's Global Campaign for the Elimination of Silicosis and the International Agency for Research on Cancer's (IARC) 1997 classification of silica as a human carcinogen.[4] In addition to cancer, the regulators continue to have their traditional concerns with respiratory problems from dust inhalation, silicosis in the case of silica dusts.[5] Some action by OSHA on silica in the near future is virtually certain because the current standard, derived from a 1962 consensus standard originally created by the American Conference of Governmental Industrial Hygienists (ACGIH), "is based on particle counting technology, which is considered obsolete"[6] and because the IARC conclusion has made clear that the existing standard, which did not consider the cancer risk, is no longer adequate. As a result, silica regulation is a "high priority" initiative at OSHA, one of only four such listed in OSHA's December 2004 unified agenda.[7]
Occupational health and environmental regulators face challenges in developing regulations that adequately address the complexity of biological, mineralogical, chemical, physical, and other characteristics of substances like silica. Too much detail induces paralysis; too little produces regulations that fail to focus on the actual harmful substances and so imposes costs without corresponding benefits.

As the In re Silica Products Liability Litigation opinion demonstrates,[8] crucial questions also arise as to the role of the tort system in regulating hazardous products.
In this Article we examine the current and future regulation of silica and the issues involved in developing new standards. In Section I, we describe the problem of categorizing the subject of regulation. In Section II, we use the experience with silica and public choice theory to focus on both the pressures agencies face and the roles interest groups play in shaping occupational safety and health regulations. This regulatory history makes silica regulation an ideal case study for examining the general problem of categorizing regulated substances. In Section III, the history of asbestos litigation illustrates the undesirable consequences of relying on the tort system to drive regulation. In Section IV, we recap the problems associated with the regulation of silica and other compounds that are difficult to characterize, and we discuss possible options for developing sound policy.
I. THE PROBLEM OF CATEGORIZATION Silica is the common name for minerals containing a combination of silicon and oxygen such as silicon dioxide (SiO ). As silica is one of the most common substances in the Earth,[9] it might appear that defining silica for regulatory purposes would be trivial. And, of course, regulators could define silica for regulatory purposes as the mineral SiO . Yet such a definition would be grossly overinclusive, potentially subjecting virtually every human activity to regulation.[10] Thus, a more sophisticated definition of silica is necessary for effective regulatory action.
Silica comes in multiple forms that have varying mineralogical characteristics. First, silica may be "free" (only SiO is present), or it may be mixed chemically with another atom or molecule.[11] This is important because only free silica is currently considered to have human health effects.[12] Further, free silica can be distinguished into amorphous and crystalline silica.[13] The former is "essentially benign," while at least some forms of the latter are potentially toxic when inhaled or otherwise ingested.[14] As we will discuss in greater detail below, however, this simple binary characterization is still too crude to capture the distinctions necessary to differentiate the risks presented by different forms of silica.[15]
The difficulties in adequately characterizing even what appears to be a comparatively straightforward, common substance like silica, which has a long history of medical study, are magnified when the issue is a substance about which little scientific research has been undertaken.[16] Unless regulators are willing to employ a version of the precautionary principle that allows them to prevent all innovation until a substance is proven safe,[17] thereby cutting off huge areas of economic activity, regulators will have to operate with a great deal of uncertainty.[18] Regulators thus need a principled approach to determining how much of a distinction to draw in characterizing the subject of a regulation.
A. Characterization The ability to regulate rests on the regulator's ability to define what is being regulated. Not only must the regulator offer a legal definition of the regulated substance, but regulators must also create a means of characterizing the regulated substance such that it can be identified using test equipment.[19] This implies the ability to define the regulated substance scientifically. Similar problems also exist with respect to non physical definitions: A regulator of a financial product must define the characteristics of the product (for example, distinguishing a stock from a bond).[20] Although we concentrate on scientific characterization for the purposes of workplace health and environmental regulation, our analysis applies to other forms of regulation as well.
A hypothetical example illustrates the problem. Suppose a substance, kryptonite, is suspected of having deleterious health effects on humans exposed to it. Further investigation reveals that kryptonite comes in two forms: αkryptonite and βkryptonite. Based on this initial investigation, it appears that only αkryptonite

causes health effects; there is no evidence that βkryptonite is harmful. But, there is also no evidence that βkryptonite is not harmful. In short, we have reason to believe that αkryptonite is harmful, although we do not know why it is harmful; we know only that βkryptonite is different from αkryptonite and that the data supporting the knowledge that αkryptonite is harmful come from studies of αkryptonite.
A regulation of "kryptonite" which does not distinguish between αkryptonite and βkryptonite will either overregulate or underregulate the uses of kryptonite.[21] If we regulate both forms of kryptonite at the level appropriate for αkryptonite and βkryptonite is not harmful (or not as harmful as αkryptonite), then we will overregulate. That is, a regulation that does not distinguish the two forms will impose unnecessary costs on users of βkryptonite.[22] As a result, users of βkryptonite will reduce output (since their costs have gone up), consumers of βkryptonite products will face higher prices, and employment will decline in βkryptoniteusing industries and in industries using products made with βkryptonite.
If, on the other hand, the kryptonite regulation regulates both forms at a level appropriate for βkryptonite, it will underregulate the users of αkryptonite. That is, the regulation will fail to impose costs, the imposition of which would yield benefits that exceed those costs. As a result, users of αkryptonite will use too much, causing harm to employees and/or consumers of products produced with the αkryptonite.
Finally, a uniform standard based on an average of the two forms of kryptonite will underregulate users of αkryptonite and overregulate users of βkryptonite. The challenge for regulators, therefore, is to properly define what they are regulating so that they avoid the twin dangers of overregulation and under regulation.
In the hypothetical we assume that both the regulators and the rest of the community know that kryptonite comes in both a and β forms, that the αkryptonite form is hazardous, and that there is no evidence concerning the β form. It is also possible that the distinction between the a and β forms is unknown and that discovering the distinction will require substantial investment in research. Without knowledge of how a substance causes harm, it is difficult to determine which types of distinctions matter. We thus may face questions not only about αkryptonite and βkryptonite but also about αkryptonite and α'kryptonite. Resolving whether there is an α'kryptonite~and whether it is the distinction between α and α' forms, α and β forms, both, or neither that matters — and doing so on the basis of ambiguous epidemiological evidence[23] and animal studies[24] — requires a substantial investment of both time and money in research.[25]
Now suppose the regulator has available only a study that shows a health impact from an unspecified form of kryptonite. The regulator proposes a kryptonite standard based on the available evidence and resolving the uncertainties caused by the necessarily incomplete evidence before it. During the comment period, an entity potentially subject to the new standard provides evidence that kryptonite exists in both a and β forms and that the studies on which the regulator relied measured only the impact of αkryptonite. Because the regulator does not know the precise mechanism through which kryptonite causes harm, he cannot know with certainty whether the α / β distinction is relevant. Because the α / β distinction was previously unknown, the regulator also cannot draw on a scientific consensus about its relevance.
How should the regulator respond to the new knowledge that the α / β distinction exists? Should he proceed to regulate only αkryptonite? Or does some precautionary principle shift the burden to the regulated parties to show that the α / β distinction is relevant to the harm caused by kryptonite? If so, how can he do so without understanding the harm mechanism? Should the regulation be delayed entirely? With respect to the βkryptonite only? How should a court treat evidence in a tort suit seeking to impose liability based on kryptonite exposure when such a distinction is demonstrated?

At some level, the burden must rest on the regulator — a showing of harm from exposure to benzene, for example, does not justify imposing regulations on cotton dust because benzene and cotton dust are easily distinguishable. But just as obviously, a showing of harm from one substance may justify regulatory action with respect to a close analogue in the absence of evidence that the distinctions between the two are relevant.[26]
We do not require individual regulations for each firm to be based on the precise chemical, physical, mineralogical, or other form of composition of its raw materials. We do require different regulations for substances that are different at a fairly crude level, even closer than the distinction between benzene and cotton dust. The questions, therefore, are where regulators are to draw the line initially and what sort of evidence from the regulated justifies shifting the line during the rulemaking process.
B. Silica Categorization and Health Effects While silica is defined broadly, silicarelated diseases are currently associated only with free crystalline silica.[27] Distinguishing between crystalline and noncrystalline silica is merely the beginning of our knowledge of potential distinctions, however. For example, the Mineralogical Society of America classifies crystalline silica into 17 forms.[28] Research on health effects focus on only four principal forms,[29] but the wider set of Mineralogical Society classifications suggests that these categories may not capture the impact of all of the potentially relevant distinctions among the types. Changes in scientific knowledge have already led to new theories about how silica causes health effects.[30] Future changes may lead to further development of knowledge. In its 2002 review, the National Institute of Occupational Safety and Health (NIOSH) recommended further research to reduce uncertainty regarding "mechanisms and the influence of particle characteristics on development of disease."[31]
Moreover, whether an individual exposed to silica dust develops silicosis depends on a range of individual factors including personal characteristics unrelated to the exposure, such as whether the individual smokes.[32] The American Thoracic Society, for example, found evidence suggesting that exposure to crystalline silica '"produces increased risk for bronchogenic carcinoma,'" but '"noted that less information was available for lung cancer risks among silicotics who had never smoked and for silicaexposed workers who did not have silicosis.'"[33] And not all dust containing free crystalline silica, currently thought to be the most dangerous, is harmful. Filtration by the nose, throat, and upper airways remove larger particles before they reach the innermost depths of the respiratory tract (alveoli or air sacs) where silicosis damage occurs.[34] The size of dust particles is thus important to determining hazard levels as well. This short summary is intended to make the point that our understanding of how silica affects human health is incomplete. Clearly we face a danger of overregulation because we do not know whether particular forms of silica are harmful, even if we are certain that some particular form is harmful.
Most recently, studies have suggested that there may be a crucial difference between freshly fractured crystalline silica and silica with older fractures. Fractured silica that has aged for weeks to months poses fewer health risks than freshly fractured silica.[35] The Sorptive Minerals Institute (SMI), which represents the absorptive clay industry, is studying the differences in health risk between exposure to freshly fractured, aged silica and the "geologically ancient" clays (fractured over eons through natural geological processes) used in that industry.[36] The initial results of its experiments suggest that the characteristics of artificially fractured quartz (pulverized, ground, blasted, or otherwise fractured by man) make it a greater health threat than respirable quartz generated through natural geological processes.
We also face the danger of underregulation. Prolonged exposure to free crystalline silica is associated with scarring of the lungs (silicosis). Silicosis is a progressive, incurable disease that impairs respiratory function.[37] It takes years to develop, seldom exhibiting symptoms in under five years.[38] Not controlling

exposure to harmful forms of silica thus risks irreparable damage to exposed individuals' lungs. As described below, the regulatory history of silica includes frequent, incorrect assertions that the problems of silica exposure had been solved by regulatory measures that subsequent knowledge revealed to be less effective than promised. In the early 1990s, 200 to 300 silicosis deaths per year were reported.[39] Further, research has recently associated chronic exposure to high levels of certain forms of free crystalline silica with lung cancer. Delay in addressing silica exposure thus also has its costs, and there is now reason to believe that those costs are larger than previously thought.
The problem of categorization is central to regulatory action concerning silica. The IARC analysis of silica dust, for example, noted that "carcinogenicity in humans was not detected in all industrial circumstances studied. Carcinogenicity may be dependent on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution of its polymorphs."[40] Determining which forms of silica pose a human health threat, and so are candidates for regulatory action, is thus key.
In sum, we know that silica can be classified in multiple ways. These classifications may or may not have a relationship to the health effects observed in epidemiological studies of silica exposure and other research on silica's health effects. We do not know, for example, exactly what form of silica medical researchers included in some early studies because distinctions now recognized were unknown or thought to be unimportant at the time the studies were conducted. Yet these distinctions are potentially as important as the distinction between silica dust and dust that does not contain silica. OSHA regulates (and is considering tightening regulations on) silica based on a recognition that silica dust is different from other dusts. If it turns out that only freshly fractured crystalline silica dust is hazardous, failing to draw that distinction will have unnecessarily imposed substantial costs on industries using other forms of silica. We are thus in the position of the regulator considering αkryptonite, α'kryptonite, and βkryptonite: We have multiple distinctions, but we do not know if they are relevant. As our ability to draw distinctions based on chemical, mineralogical, and other bases grows, it increasingly exceeds our ability to understand the relevance of the distinctions we can draw.
We have thus established the fairly obvious fact that regulators must draw lines. What may be less obvious is that the ability to draw these distinctions is endogenous. That is, the characterization of the regulated substance (and other distinctions) depends on the investment by the regulator, the regulated, and other interest groups in creating and using knowledge about the subject of the regulation. Different participants have different incentives to invest in building and using such knowledge. We discuss these incentives in the next Section.
C. Incentives for Developing Knowledge If we had complete knowledge about a workplace hazard, its risks, and its remedies, we might be able to design a comprehensive regulation that perfectly aligned protective measures and hazards, striking just the right balance between the cost and benefit of mitigation. Of course, we do not have such information about workplace hazards any more than we have it about anything else.[41] Examining attempts to implement regulatory solutions in economic policy, Nobel Prizewinning economist Friedrich A. von Hayek coined the term "the knowledge problem" to explain why centralized regulatory solutions are inferior to decentralized market processes.[42] Hayek's central point was that decentralized markets focus dispersed information — information that no one individual (not even a regulator) can obtain — and convey it efficiently to market participants.
1. Market Incentives and Market Failures To understand Hayek's point, consider the financial incentives an unregulated workplace provides for protecting health and safety. First, employees have obvious incentives to protect their own health — faced
5/11/2017 EBSCOhost
http://web.b.ebscohost.com.libraryresources.columbiasouthern.edu/ehost/delivery?sid=abc1237716e543d5adef552390caa9f8%40sessionmgr102&vid=8&hi… 6/77
with two otherwise equal jobs with different risks, employees will prefer the less risky job. Thus, informed employees will demand safeguards for health and safety.
Second, even wholly selfinterested employers have incentives to provide safe and healthy work environments to ensure a productive workforce.[43] Employers often have significant investments in their employees' firmspecific human capital.[44] Safeguarding that investment requires reducing turnover.[45] Moreover, employees in more risky jobs can command higher wages than employees with equivalent skills in less risky environments, which provides financial incentives for employers to protect the health and safety of employees, even in the absence of government requirements.[46] Indeed, even critics of market forces concede that market responses sometimes occur before regulatory action.[47] For example, systematic medical exams of employees, an important tool in uncovering workplace diseases, were part of "paternalistic programs to care for the workers' broader needs, often to wean them away from trade unions."[48]
The market failure analysis of workplace health and safety stresses obstacles to these incentives' operation. For example, some argue that because employees are ignorant of the true nature of the risks they face, they fail to demand sufficient safety.[49] Similarly, others contend that employers are able to impose onesided bargains on employees and are able to force them to accept dangerous jobs when employees would prefer safer working conditions.[50] As a result of these market failures, critics argue, an unregulated work environment would be hazardous to employees' health and safety. Because employers could impose contracts including dangerous working conditions without fully compensating employees for the additional risk, employers would choose not to invest in safety, thereby shifting the cost to employees.
2. Incentives for Categorization and Knowledge With respect to the problem of categorization, we can use our kryptonite example to illustrate how the incentives operate. Suppose we begin with the problem of kryptonite exposure generally, without regard to the various forms of kryptonite. Employers will have an incentive to invest in discovering whether there are relevant distinctions among forms of kryptonite (α, α', and β) because the discovery of a relevant distinction can reduce the risk premium they must pay to employees. Note that this benefit of increased knowledge to employers is dependent upon convincing employees that the distinction is relevant. Employers must persuade the employees to accept a lower risk premium for working with the less harmful form of kryptonite. Employers will have to make investment decisions under considerable uncertainty (since they do not even know if there are multiple forms of kryptonite, let alone whether the harm caused by the different forms, that may or may not exist, is different). The key is that the incentive exists to produce knowledge, even if the incentive is not to produce perfect knowledge.
However, market failures affect incentives to invest in categorization. If employees misperceive the risks of kryptonite generally, and so fail to demand an appropriate risk premium, or are unable to bargain for risk premiums at all, employers will have no incentive to invest in knowledge about kryptonite's potential forms. Moreover, if employees misperceive risks because they are incapable of understanding scientific evidence, [51] they will be unlikely to accurately assess the evidence produced by employers. Employers may then invest in inaccurate evidence to mislead employees about the risks of kryptonite. If the market failures dominate the unregulated market, the incentives for investing in knowledge will be diluted or destroyed, and a perverse incentive to create junk science may exist.
The choice in addressing health and safety issues is not, of course, between OSHA and the completely unregulated marketplace. We must therefore also consider the impact of intermediate regulatory measures on workplace health and safety. Since the early twentieth century, workers' compensation and other forms of insurance financed through premiums paid by employers have provided incentives for

workplace health and safety.[52] Insurance gives employers incentives to promote safety because employers with poor safety records face higher workers' compensation insurance premiums.[53] These incentives appear to have had an impact on the workplace: The doubling of workers' compensation premiums between 1984 ($15 billion per year) and 1991 ($31 billion), for example, led to significant improvements in worker safety. By the late 1990s, workers' compensation premiums had fallen to $26 billion.[54] Research suggests that, if not for workers' compensation, occupational fatalities would be one third higher than they are.[55] Workers' compensation insurance thus has had a demonstrable impact on workplace health and safety.
With respect to the incentives to understand health impacts of potentially hazardous substances in the workplace, workers' compensation insurance creates incentives for research by adding a repeat player concerned with lowering costs. Insurance companies profit from the difference between the claims they pay and the premiums they collect.[56] Workers' compensation insurers compete among themselves for employer business by offering lower premiums.[57] If an insurer can discover a basis for distinguishing among high and lowrisk employers (for example, the α / β kryptonite distinction), it can offer lowrisk employers lower premiums and win market share. Moreover, employers who can demonstrate that their workplaces are less hazardous than the workplaces of other firms by showing a distinction in exposures will be able to negotiate lower premiums. Thus, both insurers and employers have incentives to seek to increase knowledge about the appropriate categorization of workplace hazards. A complete picture of the incentives to build knowledge of workplace hazards must include the incentives of repeat players such as insurance companies.
3. Government Failures and the Role of Interest Groups Market failure theory proponents sometimes view documenting, or perhaps even simply asserting, the existence of one or both of the effects described above (employees' inadequate understanding of potential risks and inadequate bargaining strength compared to employers) as sufficient justification for state intervention. A crucial insight of public choice theory, however, is that we must consider the possibility that state interventions will make things worse. In other words, there may be a "government failure" as well as a market failure, and the means of properly judging the relative worth of alternative institutions is to compare the strengths and weaknesses of both rather than the strengths of state action with the weaknesses of market processes.[58] Understanding the complete set of institutional strengths and weaknesses requires that we consider the incentives created by both.
Moreover, we must consider the form of the intervention required to compensate for any market failures. If the problem is a lack of information among employees about the magnitude of risks, for example, providing them with the information is one means of correcting the market failure; directly specifying the risk reduction measures employers must take is another. These two solutions have different incentive effects, and the costs and benefits of each should be considered in contemplating the form of intervention.
Given the other incentives employers and employees have to protect worker health and safety, what role should federal regulation have? Traditional welfare economics argues that the existence of market failures requires government intervention.[59] It suggests that politicians seeking to serve the public interest will regulate to correct those "market failures," in which case we would see regulations enacted to serve the public interest by addressing perceived or real market failures.[60] This does not appear to be uniformly the case, however, suggesting that a richer theory of regulation is needed.[61] Many regulations do not correspond to market failures. Economic regulations, the predominate type of regulation through the 1960s, were not well correlated with identifiable market failures, and indeed, they often seemed to serve private, not public, interests.[62] In the case of OSHA regulation, empirical analysis has not found strong

evidence that OSHA regulations have had a substantial impact on worker health and safety,[63] suggesting that alternative explanations are necessary.
The understanding of regulation improved with the insights of George Stigler and James Buchanan, two Nobel Prizewinning economists. The works of Stigler and Buchanan developed insights for predicting when policymakers would promulgate regulations and the form they would be likely to take. In particular, Stigler's 1971 article, The Theory of Economic Regulation, helped raise awareness of the incentives created by regulations and wealthredistribution consequences of economic regulation. Stigler started with the premises that (1) the basic resource of the government is the power to coerce, (2) an interest group that can convince the government to use its coercive power to its benefit can improve its wellbeing at the expense of others, and (3) agents (firms, individuals, government officials, interest groups) are rational and try to maximize their own utility (wellbeing).[64]
With this foundation, Stigler set forth the hypothesis that regulation is supplied in response to the demands of interest groups acting to maximize their own wellbeing (income).[65] He observed that the behavior of legislators is driven by their desire to stay in office (maximize political support). Regulation is one way to redistribute wealth, and interest groups compete for that wealth redistribution by offering political support in exchange for favorable legislation.
The implication of Stigler's theory is that regulation is likely to be biased toward benefiting interest groups that are better organized and have more to gain from the wealth redistribution. Regulation is thus likely to benefit smaller, betterorganized interest groups with strongly felt preferences at the expense of larger interest groups with weakly felt preferences.
Buchanan's work (together with Gordon Tullock) contributed to this richer understanding of regulation through the creation of public choice theory.[66] Public choice economics begins with the recognition that (1) individuals in government (politicians, regulators, voters, etc.), just as individuals in other circumstances, are driven by self interest and (2) these individuals are not omniscient.[67] Public choice theory argues that government officials cannot simply systematically maximize the public interest. For example, to produce favorable outcomes, even a benevolent politician must be in office. To gain and retain office, the politician must obtain campaign funds and votes; getting both requires cooperating with interest groups seeking to maximize their own welfare. Thus, public choice economics reach conclusions similar to those drawn from Stigler's economic theory of regulation. Public choice also recognizes that, because policymakers are not omniscient regarding the consequences of different policy choices, their interventions, even when designed to correct market failures, may produce "government failures."[68]
The insights of public choice theory and the economic theory of regulation shed new light on when we are likely to observe regulation and the forms it will take. Crucially, they tell us that we need not rely on bad actors in government to explain suboptimal outcomes. Good people, with pure motives, will also produce special interest regulations due to the structure of the political system. Thus, small, organized interest groups can exercise the political will to gain specialized benefits while spreading costs to large unorganized citizens. To study regulation, therefore, we must understand the interest groups that have a stake in regulatory actions and the political players involved.[69]
II. AN INTEREST GROUPBASED ACCOUNT OF SILICA REGULATION In Section I, we argued that significant problems must be resolved for the design of effective regulatory measures. In this Section, we turn to the regulatory history of silica dust because understanding regulatory outcomes depends on the examination of the roles interest groups and incentives play in shaping regulatory policy.

A. The Early Awareness of the Health Risks of Silica Silica is everywhere — it is the second most common mineral in the earth's crust.[70] Silica dust is a highly visible air contaminant, unlike many other workplace hazards like gases that are potentially carcinogenic at low concentrations and difficult to identify in the workplace. Dust, after all, is generally visible to the naked eye even if the specific particles that are most hazardous are not. Discussions of silica and silicosis often begin with a quote from De Re Metallica, a sixteenthcentury treatise on mining, by the German scholar, doctor, and founder of modern geology Georg Bauer (also known as Georgius Agricola), or another source of similar historic vintage to make the point that the hazards are wellknown.[71] Such accounts are at least partially correct. By as early as the end of the nineteenth century, occupational health writers had clearly established a relationship between dusts, including silica dusts, and health.[72] Thus, the hazards of silicosis are not a new discovery, even though the complexities of its cause and effect are still being explored today.[73]
A conclusion one might draw from these venerable sources is that the market has clearly failed with respect to dust exposures. How, after all, could hundreds of years of exposure to dangerous dusts occur unless there was a market failure? The answer lies with the evolving nature of scientific knowledge and the nature of dustinduced health problems. Despite widespread general knowledge that dust exposure posed risks, in fact little specific knowledge existed as to the types of risks with which we are concerned today. Nineteenthcentury and earlier observers could see dust in the air in mines and other workplaces and observe that some of the employees working in those locations became sick. They had little accurate knowledge about why the employees became ill, why some did and some did not, and how the dust they observed was connected to the illness. Conditions in these workplaces were generally quite different from those that prevail today. Exposures in preindustrial economies, for example, tended to be limited to a few highrisk occupations (for example, mining). Even in those occupations, the technology used in pre industrial Revolution mining differed from modern methods, and it produced different types and volumes of dust. We remember the successful identification of the association between dust and silicosis, forgetting the many similar theories that have since been proven wrong (for example, the connection between "miasmas" and disease).[74] We cannot conclude from Agricola's writings that the public widely understood that the conditions he observed caused disease. Nor can we conclude that the absence of action to control the dust hazard until the twentieth century represents indifference to the health and welfare of the employees by either the employees themselves or their employers.
B. From the Industrial Revolution to the New Deal Although miners and some other occupations had experienced dust exposures for centuries, the development of power tools and other new technologies as a result of the industrial revolution dramatically changed the scope and type of dust exposure for employees in a wide range of industries.
1. Industrialization's Impacts Industrialization in the United States brought a sharp increase in accidental deaths and injuries.[75] Throughout the late nineteenth and early twentieth centuries, Americans grappled with a number of responses to the problem. Not surprisingly, given the toll from accidents, the problem of workplace disease was not the first priority.[76] The initial response to the increased accident rate was an "outpouring" of new tort litigation despite the restrictive tort doctrines that made suits difficult for plaintiffs to win — between 1870 and 1910, tort cases in New York City had grown from 4.2% to 40.9% of the trial court caseload.[77] Complaints concerning the plaintiffs' bar used alarmist terms: '"barratrous speculations,'" '"communistic tendencies,'" and '"enormous verdicts'" all contributed to the denigration of'"manly and professional dignity'" at the bar.[78]

Dust may not have been at the top of the social agenda, but it too was affected by industrialization. As a result of technological change, the scope of the dust problem grew dramatically with the Industrial Revolution.[79] Exposure to silica dust increased sharply in the early years of the twentieth century after the invention of the pneumatic hammer drill in 1897 and sand blasting in 1904.[80] The new technologies meant that more dust was made up of smaller particles.[81] Although no systematic measurements existed, federal studies conducted by the Bureau of Mines found that mines in Joplin, Missouri and Butte, Montana contained dust levels at more than 100 times the levels later allowed under the OSHA standards imposed in the 1970s.[82] Even in states with laws requiring ventilation of dusty workplaces, insufficient knowledge resulted in laws that lacked specificity in defining meaningful exposure or ventilation levels.[83]
Further, the limits of pretwentiethcentury medical knowledge significantly hampered medical diagnosis of dustrelated injuries. The absence of Xray technology severely limited the ability to examine the lungs of living patients,[84] and the lack of the germ theory left doctors without a correct causal understanding of much of what we take for granted in medicine today.[85] For example, scientists had trouble distinguishing tuberculosis from lung scarring caused by dust exposure.[86] Even today, radiographic techniques cannot distinguish silicosis from many other respiratory diseases.[87] Similarly, variation in individual susceptibility to various industrial hazards discouraged investment in general mitigation measures solely because some employees became ill.[88] Medical standards changed rapidly in the first quarter of the twentieth century, becoming more sciencebased and making much greater use of technology.[89] This included expansion of information technology such as punch cards, which enabled the tracking of patterns of disease.[90]
Pretwentiethcentury understanding of dust hazards was primitive by modern standards, and improving that understanding ultimately required technological change (the invention of radiography in 1895)[91] and scientific breakthroughs in medicine (the germ theory's impact on medicine in the 1870s and 1880s).[92] Although the discovery of Xray technology prompted a massive reaction almost overnight — machines were for sale in the United States for $50 within a short time after the discovery of the technique in Germany, and more than 1,000 articles and 49 books on the topic appeared in the first year after its discovery[93] — it took time for the practical application of it to spread beyond major urban centers.[94] It also took time for the new technology to become accepted as a vital part of diagnosis even for obvious conditions such as broken bones.[95] Finally, although the technology was certainly available by 1900, major innovations in reducing the cost of its use were not realized until the demands of World War I prompted innovation.[96]
In addition, before the twentieth century, public health was "still largely the province of amateurs and gentlemen,"[97] and the gentlemen did not have the tools or the political base to demand resources. Only when private foundations and state governments began funding research in the first years of the twentieth century did a more systematic analysis of workplace safety and health begin.[98] The demand for more knowledge about dustrelated health hazards also grew because of the changes that the Industrial Revolution introduced in factories.
Slowing the development of accurate knowledge of the causes of workplace diseases
was the ambiguous way that occupational ailments often manifested themselves. Even widely recognized industrial diseases could be difficult to identify with any certainty in a given worker. Ailments without characteristic signs of their occupational origins, such as cardiovascular illnesses, many muscular strains and cramps, or even the infectious lung

diseases that often complicated silicosis, were easily attributable to nonoccupational rather than workplace causes. Even for those diseases more specifically connected with certain occupations, like lead poisoning, recognition could be difficult.[99] A close look at when knowledge developed supports this account. An article published in 1900 in the Journal of the American Medical Association became the first major U.S. medical publication to identify silica dust as the cause of fibrosis.[100] It discussed elevated death rates following the introduction of mechanical milling equipment in a Nevada gold milling firm.[101] British researchers also documented problems in South African mines in this same period.[102] Significantly, dust hazards were first documented in the context of high exposure occupations (mining and milling) in which new techniques increased the hazard at the same time as new medical technology and knowledge made diagnosis possible.
The public reacted to the new knowledge by demanding yet more knowledge. As early as 1911, for example, an insurance company statistician pushed for a federally funded study into the health of metal miners.[103] Insurance company interest in the subject is not surprising: Some estimates today are that "at least thirty thousand" metal miners "at any time" during this period had silicosis.[104] And insurance policies for factory workers had boomed in the preceding decades — estimates run as high as 3.5 million policies by 1900.[105] New knowledge was produced — "By the 1920s, silicosis was established as an important industrial disease."[106] The new knowledge was far from complete: "[S]ilicosis was perceived as a problem affecting rural, relatively isolated populations in widely scattered communities" rather than as a widespread problem.[107] Knowledge about silicosis grew together with more general knowledge about workrelated disease — Professor Sellers concludes, for example, that the field of industrial hygiene "coalesced between the 1910s and 1930s."[108] Viewed in light of contemporary knowledge and technology, the market reacted to the unprecedented increases in silica dust exposure caused by the new technologies around the turn of the twentieth century by demanding knowledge. Insurance companies, among others, stood to profit from creating better understanding of the health effects of silica dust exposure, and as diagnostic technology advanced and medical knowledge improved, private interests reacted to the increased exposure and resulting increase in silicosis by investing in knowledge. These investments appear to us to have been made faster than would have been expected given the long latency periods for silicosis. Far from a market failure, this initial response appears to have been quite rapid in light of the uncertainties in medicine, primitive understanding of the disease, long latency period, and rapid technological change.
2. The Reaction of Interest Groups The same industrial innovations that produced finer and more dangerous dust also led to major increases in labor productivity and, as a result, produced significant dislocations in a number of industries.[109] For example, in the nineteenthcentury foundry industry, mouldmaking was a skilled occupation[110] supported by a great deal of semiskilled and unskilled labor.[111] Starting in the twentieth century, much of the support work was mechanized and output soared: "By the early years of the [twentieth] century, one worker running a machine mixer for two hours could mix as much sand [for moulds] as two workers mixing by hand for an entire day."[112] Craft workers generally resisted employer control over their work,[113] which limited employer knowledge about hazards. For example, Sellers reported that:
[T]he Wheeling nail manufacturers rented out nail‐making machines on their premises and paid nailers by the piece; otherwise, they left many of the nailers' working methods in the hands of the nailers themselves. Many

Wheeling nailers chose not to wet down their cutting machines, which would have reduced the volume of dust to which they were exposed, because dry nail cutting went faster and paid better — at least over the short term.[114] In the case of the mouldmakers, pneumatic tools for cleaning cast items also raised efficiency, as did the addition of power tools to the finishing stages of polishing and grinding.[115] The biggest change was the introduction of moulding machines that replaced the skilled mouldmakers.[116] These innovations also created greater silica exposure, since the power and pneumatic tools both created more dust and blew more dust into the air.[117] The increased production raised exposures, as did the expansion of the industry triggered by the falling prices of iron products due to higher labor productivity.
In this environment, it is not surprising that occupational disease issues became an important bargaining tool for unions.[118] The same changes that threatened union members' positions within firms threatened the health of their members. Employees also resisted safety measures at times, not accepting the new equipment and methods either because they did not believe them safer or because the changes reduced income as well as increasing safety.[119] Opposing technological change is difficult without a nonLuddite rationale, and health issues provided unions with the means to seek to control the impact of technology in the workplace. Similarly, as the number of small foundries grew in the late nineteenth and early twentieth centuries,[120] unions must also have seen the health issue as a means of limiting this competition to the larger, unionized shops since the smaller shops generally could not afford to follow the safety standards set by the larger firms.[121] The craftbasis of early twentiethcentury American unionism limited its effectiveness by fragmenting workers in each shop.[122]
The early twentieth century also saw the passage of state laws protecting the health of employees and the creation of agencies that investigated factory conditions and occupational health issues, part of the Progressive Era tendency toward expert agencies. The organization of the American Association for Labor Legislation (AALL) in 1906 created a lobbying group seeking labor legislation and supporting its demands through conferences, investigations, and reports.[123] It held its first national conference on industrial disease in 1910.[124] The organization also sponsored publication of papers on the topic. As a result, after the publication of papers from the second AALL conference, American publications exceeded those of the former leaders — the British and the Germans.[125] The AALL made occupational diseases one of its top priorities.[126] The policy entrepreneurs of the AALL, who included Richard Ely and John Commons, sought to define a "scientific" path to legislation that would improve human welfare.[127] In doing so, they helped create a "more coherent field of study" dealing with occupational disease.[128] Undoubtedly motivated by concern for the general welfare, these experts also "aimed to secure a place for their professions" in public policy.[129]
Popular demand for action grew, in part, from media accounts of workplace hazards. Magazine and book publishers printed regular accounts of workplace disease and injury because such stories sold magazines. [130] State factory inspectors grew in number nationwide, from fewer than 300 in 1907 to 425 in 1911. [131] In the process, they helped create a constituency for legislation.[132] Organizations representing a variety of interest groups sprang up in the 1910s.[133] By 1914, 33 states had created factory inspection bureaus,[134] 15 states had passed legislation requiring reporting of occupational diseases by all physicians,[135] and 25 had passed workers' compensation statutes.[136] World War I's demands on the economy and labor stimulated even greater interest in industrial hygiene.[137]
While these first agencies' capabilities were rudimentary,[138] reflecting the scientific standards of the time, their creation meant that a state bureaucracy now invested in documenting occupational diseases.

Not surprisingly, these new agencies quickly expanded: New York went from one to four doctors between 1922 and 1924; Connecticut formed a "Division of Occupational Diseases" in 1928 and had "both a physician and an 'industrial hygienist' on its staff by 1930."[139] The federal government also funded studies aimed at occupational disease.[140] Workers' compensation statutes spurred companies to hire plant physicians — a Public Health Service study in 1919 found "118 out of the 170 plants questioned paid a physician for services, either parttime or fulltime."[141] This interest by governments spurred further market responses: The first American textbooks on occupational medicine appeared in 1914,[142] and Harvard appointed the first fulltime professor of industrial medicine in 1919.[143] The initial state response mimicked the private sector response: investing in creating knowledge.
3. Workers ' Compensation As a result of the increase in workplace hazards brought about by industrialization, a broad coalition developed in favor of legislation to address the problems it posed for employers, employees, and insurance companies.[144] Employees wanted compensation; employers and insurance companies wanted limited liability; social reformers wanted more state intervention in the workplace. Moreover, reformers often believed regulatory solutions to be inadequate, turning to the financial incentives offered by the insurance approach.[145] The primary result in the United States was the development of the workers' compensation system for industrial accidents (although initially not for workplace diseases), a compromise that limited employers' liability and increased employees' certainty of recovery.[146] Other new initiatives included the establishment and expansion of state labor agencies, the creation of the federal Department of Labor, and the passage of various acts regulating working conditions in specific industries.[147]
The first wave of workers' compensation statutes, however, did not address diseases. Why not? Several factors contributed to the initial focus on injuries rather than disease, a relatively crude version of the categorization problem. First, workers' compensation, so commonplace today, was a radical innovation at the time.[148] Second, mass industrial disease, as opposed to isolated incidents, was still relatively unrecognized. The long latency periods (as much as twenty years for silicosis)[149] and relatively primitive understanding of medicine made diagnosis of nonacute conditions challenging.[150] The industrial changes that increased exposure combined with the latency period to make the real boom in disease recognizable only after state legislatures had passed the first wave of workers' compensation statutes. [151] One key result of the introduction of workers' compensation insurance, however, was that a lawyer named Crystal Eastman began to gather statistics on the causes of injuries.[152] A benefit of workers' compensation acts was that they "moved analysis of work accidents from the close specificity of individualized inquiries into particular accident cases to a higher plane of statistical generality."[153] Insurers sought to introduce preventative measures to lower risks.[154] It worked: "From 1907 to 1920, workfatality rates per manhour in American industry dropped by twothirds; nonfatal workinjury rates and lost workdays per manhour … appear to have declined by half."[155]
Interest in such issues remained at the state level in part because the federal government had not yet become large enough to make a difference. "State and local government expenditures were about five times larger than the federal budget in 1929" — federal expenditures represented a mere three percent of gross national product that year.[156]
The 1920s were a time of economic growth and advancement for employees. Industrialization brought new material wealth:

working‐class people, many of them involving durable goods such as radios, washing machines, and even automobiles…. All experts agreed that by the end of the 1920s, the nation's working people had greater access to health care, recreational and cultural facilities, public services, and education than ever before.[157] Prices for consumer goods were falling rapidly, putting them within the reach of an everwidening proportion of the country's population.[158] Labor peace largely prevailed, with strike activity reaching historic lows.[159] "Welfare capitalism" meant that employers had taken the initiative in addressing a wide range of issues for employees, defusing employee interest in initiating workplace reforms.[160] Not everything was perfect; unemployment remained a concern for many, reaching eight percent in mid1929. [161] Nonetheless, the success of so many during the 1920s resulted in little demand for tackling hard to understand problems like silicosis. Unions, the one interest group that might have spurred public interest, were preoccupied with declining membership — a sympathetic observer says the American Federation of Labor (AFL) "languished in torpor and apathy throughout the 1920s"[162] — and losing ground because it had not yet cracked the mass production industries.[163] Most importantly for explaining the lack of state interest in issues like silicosis, the AFL unions, under Samuel Gompers' philosophy of "voluntarism," largely shunned involvement with the government.[164] To the extent that the pre1930s responses to silicosis (and industrial diseases generally) seems inadequate in retrospect, the inadequacy was a failure of both the market and the state, for neither anticipated the full impact of silicosis. From the vantage point of today, this may seem surprising, but the long latency period and lack of understanding of the disease explains why neither state nor market responded more quickly.
4. The Silicosis Crisis of the 1930s Because most of the first wave of workers' compensation legislation had either explicitly excluded or not explicitly included industrial disease,[165] workers who became ill as a result of dust exposure sought relief in the courts. Where some industrial disease coverage was provided, legislatures adopted it as "a conservative alternative to plans for statesponsored health insurance."[166] Lawsuits over silicosis from workplace exposures began to proliferate in the 1930s.[167] Thousands of such suits created a liability crisis[168] and made silicosis "an issue of national import."[169] Insurers reported that they faced '"the most serious claim problem ever encountered'" as a result of silicosis suits.[170] More than a billion dollars of silicosis suits were pending in 1934,[171] the equivalent of over $14 billion today. One important reason these suits increased dramatically in the 1930s was that silica suits offered a means to survive the Depression, converting the tort system into a rudimentary social welfare system,[172] and "as workers won their suits, it emboldened more of the unemployed and their lawyers."[173]
A variety of factors might explain the explosion of silicosis litigation in the 1930s. One is undoubtedly that silicosis's long lead time meant that incidence of the disease lagged the introduction of dustproducing equipment in various industries.[174] Both researchers and the public understood silicosis less well than many other industrial diseases, as "researchers had great difficulty devising experiments or other kinds of investigations that persuasively established the chain of events between contact with silica dust and actual symptoms."[175] Another important factor, however, is that the Great Depression created economic conditions that led "workers to use the issue of industrial illness as a means of achieving social welfare objectives."[176] Lawsuits filed by "workers in the dusty trades"[177] "brought 'silicosis within the range of practical politics.'"[178] Faced with an "actuarial potential for disaster,"[179] employers and political leaders experienced enormous pressure to find a solution. Yet another reason is the federal funding that flowed from the new Social Security Act to state boards of health to establish industrial hygiene divisions,[180] agencies that then assembled information on the state of occupational diseases in various industries.

Finally, the Gauley Bridge disaster (discussed in more detail below),[181] in which hundreds of men lost their lives to acute silicosis, spurred congressional hearings and litigation in 19351936.
Many of these suits, of course, involved genuinely injured individuals who had suffered real damages and who properly sought compensation through the tort system. Others, however, did not. Accurate diagnosis was difficult, yet some experts felt that too many doctors were willing to support doubtful claims based on unskilled readings of radiographs.[182] Silicosis suits brought with them bitter disputes over alleged fraudulent claims such as those detailed in articles like The Dust Hazard Racket[183] and those evidenced by fights between insurance companies and their insured over coverage.[184] As one observer in the 1930s complained,
Missouri is a paradise for this type of racketeering. Under its law 9 jurors out of 12 may decide a case. Though the laws against barratry and champerty are still in existence they are apparently forgotten. Plaintiffs' attorneys have employed runners, or solicitors to comb the state, paying particular attention to the unemployed. As much as $25 a case is paid to solicitors for every signed contract brought in. Cases are taken on a 50 per cent contingent basis and notices under the attorney's lien law are promptly served on the employer. At first the solicitors confined themselves to cases where some disability existed. More lately solicitation has been carried on among workers still engaged in active work, who have no more outward appearance of disability than the dust on their clothes and some outward appearance of age.[185] This scenario presented a crisis when people without injuries took advantage of some states' looser standards to bring fraudulent claims.
Eventually the "crisis" abated with the shifting of silicosis suits to the workers' compensation system beginning in the mid1930s.[186] What brought about the change? In some states, court rulings added silicosis or other industrial diseases to workers' compensation. In California, for example, a ruling by the state supreme court that the limitation period for occupational disease claims would be based on when the disease was discoverable, not when the exposure occurred,[187] led insurers to seek substantial rate increases (from $11 for every $100 of payroll to $22.25 for every $100 of payroll in the case of underground gold mines, for example)[188] and prompted legislative action. The wave of suits, partially spurred by the Depression, got employers' attention, and their liability insurance companies were presumably anxious to add the workers' compensation insurers to the defense team.[189] Life insurance companies were worried that they had covered people now likely to die far earlier than the companies had predicted. Covering industrial diseases fell within the interest of a wide range of groups, including both employees and employers.[190] The growing experience with accident coverage through workers' compensation insurance inspired confidence that the system could absorb disease claims. And, finally, the results of the increased exposures to dust and other workplace disease agents was now producing enough injured employees to attract attention. In particular, the Gauley Bridge disaster put a spotlight on silicosis.
5. The New Deal

The initial wave of New Deal labor legislation did not address occupational disease issues. Preoccupied with attempts to deal with the staggering economic crisis of the Great Depression, and without the guidance of a coherent theory on how to do so, the Roosevelt Administration embarked on a raft of economic reform measures. One of the most far reaching was the National Industrial Recovery Act and the agency it created, the National Recovery Administration (NRA), the essence of which was hostility to the idea of competition.[191] Led by Hugh Johnson, who envisioned the agency as "a giant organ through which he could play on the economy of the country,"[192] the NRA quickly "mushroomed into a bureaucratic colossus" with a staff of 4,500 overseeing "more than seven hundred [industry] codes, many of which overlapped, sometimes inconsistently."[193] These codes cartelized "huge sectors of American industry."[194] Trade associations and large producers dominated the NRA codes.[195] Despite the varied efforts and alphabet soup of agencies and statutes, the New Deal was sputtering by 1935. Unemployment remained at twenty percent, and opposition on both the right and the left began to grow.[196] 1935 saw the launch of the "Second New Deal," a new wave of proposed regulatory statutes including "the Emergency Relief Appropriation Act, the Banking Act, the Wagner National Labor Relations Act, the Public Utility Holding Companies Act, the Social Security Act, and the Wealth Tax Act," which were, in part, designed to head off the threats from populists Father Charles Coughlin and Senator Huey Long. [197] One key event spurring the expansion of the workers' compensation system to cover industrial disease was a particularly horrific series of 500 deaths (out of 2,000 employees) from acute silicosis during the 1929 tunnel project in Gauley Bridge, West Virginia. Another 1,500 were eventually disabled from chronic silicosis.[198] The tunnel route, unfortunately, ran through a vein of almost pure quartz, producing extremely high exposures.[199] The story broke nationally in 1936.[200] As one account noted, '"Popular interest in silicosis, stimulating social and legislative activities and affecting judicial decisions, was notably accentuated by the newspaper notoriety of the Gauley Bridge episode.'"[201] Indeed, some federal officials felt that the Gauley Bridge disaster advanced occupational disease legislation "almost a decade." [202]
Congressional hearings were held in 1936,[203] and the federal Department of Labor convened national conferences on the topic to encourage legislation in the states, beginning just three weeks after the congressional hearings concluded.[204] By creating a national debate over the subject of silicosis, and bringing together both labor and industry representatives in a forum, the government attempted to make it possible for the parties to bargain their way to a mutually advantageous solution,[205] in keeping with the Administration's corporatist approach to labor issues.[206] The combination of the threat of silica suits against employers, ambiguity in many states' workers compensation laws on occupational disease coverage,[207] causation issues for plaintiffs,[208] and unions' interests in using the issue to expand their role in the workplace[209] made gains from cooperation possible: Employers could eliminate the threat of civil suits, and unions could expand their influence over the workplace[210] through a new federal agency. [211] Indeed, "[i]n the midst of the Depression, silicosis was frequently framed as a labor and management problem, not solely as a health issue."[212] Unions in the mid1930s were on the upswing; after dramatic declines to fewer than three million members over the 1920s and early 1930s, union membership reached nine million in 1939.[213] However, the disputes between the AFL and the Congress of Industrial Organizations (CIO) divided the unions and weakened their political clout.[214] Economic conditions were also turning against the unions. In 1937 the recovery collapsed, and the "Roosevelt Recession" began, ending the active phase of the New Deal.[215]
Employers, however, resisted the quasiFaustian bargain; the main impact of the federally sponsored conferences was to spur the opposing sides to organize nationally to battle for control of the workplace. [216] Faced with the threat of moves to create another of the New Deal "alphabet" agencies (the leading congressional figure in the Gauley Bridge hearings advocated federal solutions),[217] employers opted for the devil they knew — workers' compensation. The change was evident, in the sense that "[b]y the end of

1937, fortysix states had enacted laws covering workers afflicted with silicosis."[218] By way of comparison, only 15 states covered some or all occupational diseases at the start of 1936.[219]
Workers' compensation was not the only area in which state involvement in industrial disease expanded during the 1930s. The Roosevelt Administration offered states financial incentives to expand their involvement: 19 states established industrial hygiene departments by 1936 in response to a federal initiative that made Social Security funds available for such departments through the Public Health Service; only seven had had such programs before 1935, and those were "of a limited nature."[220] Federal spending on industrial hygiene rose quickly, from $100,000 in 1936 to almost $750,000 in 1938. [221] State budgets rose to $589,000 in 1938, with 161 employees across 26 states.[222] Importantly for future activity, the Temporary Conference of Official Industrial Hygienists organized in 1936 and would soon become the influential National Conference of Governmental Industrial Hygienists (NCGIH), and in 1946, the American Conference of Governmental Industrial Hygienists (ACGIH), which continues today. [223]
6. Explaining the 'Moderate' Outcome One important reason industry was able to head off regulation was that employers organized quickly in response to the federal interest in Gauley Bridge.[224] Employers saw union efforts to control the workplace as a serious threat to the productivity gains of the first part of the twentieth century.[225] The opening years of the New Deal had made clear the stakes and the Roosevelt Administration's likely approach to labor issues.[226] The Air Hygiene Foundation was quickly established to serve as a clearinghouse and establish voluntary standards.[227] It conducted "nearly all" silicosis research after its establishment.[228] And despite employers' fears of New Deal legislation, given Roosevelt's status as a "diffident champion of labor, and especially of organized labor unions,"[229] the Administration did not strongly resist employer efforts to head off stronger reform efforts.
To the extent that they sought to use the Gauley Bridge incident to create federal authority over occupational health, the unions overreached.[230] And organizing, not occupational health, was the top union priority in 1936 and 1937.[231] The unions were also resisting provisions of industrial disease legislation that might lead to afflicted employees losing their jobs.[232]
Although labor interests succeeded in getting legislation introduced in Congress to implement their approach in the late 1930s,[233] by that time a conservative coalition had emerged in Congress with the strength to block the legislation,[234] and the White House did not push the legislation through.[235] Moreover, the Supreme Court had not yet "switched" to allowing the Roosevelt reforms,[236] and Secretary of Labor Francis Perkins was worried over the Court's possible attitude toward labor legislation generally.[237]
Another reason why more radical solutions were not adopted was that many viewed the problem as largely solved. Perkins,[238] for example, told the second national conference on silicosis that "its present hazards [can be] reduced to a minimum and the disease itself finally eradicated,"[239] and employer representatives confidently asserted that ventilation equipment's development had reached the point that '"the existence of a dust hazard is already on its way out.'"[240] Moreover, experts thought that only two percent of the workforce was at risk and only half of that number was at serious risk.[241]
The problem of "dust rackets" grew out of the lagging medical technology for determining causation. Dust related diseases, and occupational diseases generally, were hard to diagnose definitively.[242] Without the diagnostic tools to attribute illness to exposure, the tort system risked both under and overinclusiveness. Where rigorous causation standards applied, even plaintiffs genuinely injured by an occupational exposure were unlikely to prevail. When the plaintiffs' bar gained relaxed proof and pleading standards, de facto, if

not de jure, fraudulent claims could prevail as well as legitimate ones. Of particular relevance for our discussion is the institutional response to the silica litigation: Life insurance companies took an interest in the question because it affected their payments on policies.[243] The insurance companies also developed the data that unseated the bacteriological theory.[244] Significantly, only a few decades earlier an actuary who addressed the 1893 World's Fair "Auxiliary Congress" "wistfully concluded [that], most 'hazards of occupations' were 'unknown and almost incalculable.'"[245] In a short time, motivated by the desire to increase profits by accurately classifying risks, the insurance industry helped create a revolution in knowledge about industrial disease.
Attempts to resolve the failure of the tort system by including silicosis as a compensable occupational disease under state workers' compensation statutes brought financial stresses and demands for fiscal reforms to those systems.[246] Causation issues plagued both common law and workers' compensation solutions, as silicosis and tuberculosis often went hand in hand.[247] Moreover, susceptibility to silicosis is related in part to characteristics of the exposed individual, including both voluntary — for example smoking — and involuntary — for example genetic — characteristics,[248] creating additional problems for both tort and insurance solutions. Such transfers failed to resolve the fundamental problem of determining who had a covered disease and simply shifted the problem from the tort system to the insurance system.
To summarize, by 1940 the legal treatment of silica dust had undergone several key changes. Although the medical community had long recognized that breathing dust was unhealthy, it was not until industrialization greatly increased dust exposures (and other hazards) that American jurisdictions adopted regulatory measures aimed at workplace hazards generally or silica dust in particular. The increased injury rates of the new mechanized factories, mines, and other workplaces helped produce a broad coalition that demanded legislation to spread the costs. In a compromise between labor and industrial interests, both sides accepted workers' compensation systems to spread the costs of accidents. Eventually, the increase in industrial diseases, especially silicosis, led to their inclusion in the system as well. This latter development did not occur until the financial pressure of silicosis lawsuits produced a new broad coalition in favor of action. In essence, industrial interests found workers' compensation coverage less of a threat than the numerous suits brought by alleged silicosis victims and the possibility of federal intervention.
The institutional response to silica dust during the first part of the twentieth century is thus understandable in the interest group framework. Mechanization led to a greater demand among those injured. Institutional entrepreneurs responded to this demand by innovating (the workers' compensation system coverage of accidents, the 1930s silicosis lawsuits, and the extension of workers' compensation to cover silicosis and other industrial diseases). Further, the interplay of interest groups produced compromises as well as new institutions.
The categorization problem arose in the context of these debates. Silicosis and other industrial diseases were covered by the new institutions; tuberculosis and other "social" diseases were not. This was not a foregone conclusion; labor and leftwing interests campaigned early for a comprehensive approach to public health rather than a workplacespecific approach.[249] The outcome of the debate, however, introduced a legal distinction between the two types of disease.
Implementing the distinction proved difficult. Diagnosis was — and remains — a challenge; early twentiethcentury medicine was not up to the task of definitively determining whether a particular individual was sick because of occupational exposures or because of other factors. As a result, distinctions that later came to be seen as arbitrary were introduced, such as the requirement that radiographic evidence be used to diagnose lung conditions rather than loss of capacity.[250] By awarding benefits for a subset of employees with reduced lung capacity, the institutions that grew out of the 1930s created incentives both

for employees to be diagnosed with silicosis and other covered diseases rather than other conditions and for employers to seek different diagnoses for claimants, in order to eliminate the need to pay compensation. This line of division became politically determined because the categorization issue could not be settled objectively.
C. World War II to OSHA During the war, labor became, "in effect, a ward of the state."[251] The Roosevelt Administration protected unions from decertification but demanded and received a "no strike" pledge and wage restraint in return.[252] Labor demands after the end of the war centered on wages.[253] The passage of the Taft Hartley Act in 1947 made union organizing more difficult.[254] After the war, "national labor leaders in both [the AFL and the CIO] came to see the labor movement's political goals as broadly conceived support for lower and middleclass Americans."[255] Politically, the union movement "align[ed] itself squarely with the larger liberal agenda of countercyclical public spending and generous programs of social protection."[256] This more general focus to labor activism meant attention shifted away from workplace issues like industrial diseases. As in the 1920s, the expanding economy during the 1950s and early 1960s brought prosperity that dulled the union movement's appetite for institutional reform.[257] Moreover, the postwar industrial relations system centralized wage and benefit issues, but left "matters related to work rules, discipline, job assignment, and grievances" to local unions to resolve.[258]
The most important changes in workplace health thus came from the private sector. Industry turned to the industrial hygienists' trade organization for standards. The ACGIH, which had expanded its membership criteria to offset the decline in government activity after the war,[259] began to receive requests from firms for standards governing workplace exposure.[260] The organization formed the Committee on Industrial Hygiene Codes, and it created a table of "maximum allowable concentrations" (MACs) as a first step toward a comprehensive industrial hygiene code in 1946.[261] A separate Technical Standards Committee also considered the issues and took over the project.[262] The organization also took advantage of increased interest in the subject during the war "to organize and develop industrial hygiene agencies where they had not previously existed. By the end of the war a network of units had been established in nearly every state and many large industrial cities."[263]
ACGIH then published its maximum allowable concentrations as "Threshold Limit Values" (TLVs).[264] The organization insisted that the TLVs were merely guides and not "fine lines between safe and dangerous concentrations."[265] Despite regular repetition of such warnings, however, many states used TLVs as legal limits in statelevel workplace regulatory schemes,[266] and they continue in widespread use around the world.[267] The TLVs offered firms a focal point around which to structure their workplace safety campaigns, without requiring the firms to invest individually in the research necessary to set them. And firms could point to their compliance with "industry standards" if questions were raised about particular substances. The range of substances to which employees were exposed grew with the postwar explosion in the chemical industry, but there was no increase in dust exposures comparable to that introduced by the industrial revolution.
The one industry in which dust exposures increased dramatically was coal mining, which the United Mine Workers encouraged to move toward greater mechanization,[268] and the industry became virtually completely mechanized after the war.[269] In this one industry, we do find persistent efforts to create regulatory measures. Congress introduced a series of bills during the 1950s proposing federal investigations of mine safety issues generally; some of these singled out silicosis for special mention, and others did not.[270] The International Union of Mine, Mill, and Smelter Workers, working with Montana Democratic Congressman Lee Metcalf, was a major force behind these bills.[271] In 1958, Congress

appropriated $128,000 in funding for a Public Health Service study,[272] and in 1961, Congress authorized a federal study of health and safety hazards in mines (excluding coal mines) and quarries.[273]
As with silicosis, lung injuries from coal dust (referred to as black lung) were wellknown but were not yet the focus of government action.[274] The problem of black lung came to the forefront at the same time as the Johnson Administration began a push for general occupational safety and health legislation.[275] Ralph Nader, for example, began a public campaign in 1968 to spur federal action on black lung with an article in The New Republic and a public letter to Interior Secretary Stewart Udall.[276] Coupled with a heavily publicized West Virginia coal mine explosion later that year,[277] Nader's campaign pushed black lung to the forefront of public awareness. The mine disaster "badly tarnished" the industry and made it more willing to accept regulation.[278] The following year the new Nixon Administration introduced a federal mine safety bill, which at least some observers termed stricter than the Johnson Administration's efforts.[279] Many coal companies, which oil companies recently acquired, accepted regulation to help head off strikes.[280]
Despite the increased activity of the ACGIH, from World War II until the creation of OSHA in 1970, there was little federal or state action on silicosis or related diseases. Indeed, after the war, government funding for industrial hygiene fell,[281] and the profession declined despite the appearance of new technologies that posed new dangers in the workplace.[282]
Nevertheless, the ACGIH was active. Between 1961 and 1970, it issued 220 TLVs, bringing the total to 500.[283] ACGIH, and the TLV committees within ACGIH,[284] had considerable autonomy. The organization rejected the consensus approach of the American Standards Association because its members asserted that experts should set the health standards without interference from outsiders and that ACGIH members' governmental employment freed them from conflicts of interest.[285] But, public choice theory raises the question, what were ACGIH's and others' interests in the regulatory adoption of the TLVs?
First, the organization delivered professional status to its members, allowing them to both improve their status within firms and bureaucracies and to raise the profession as a whole.[286] The ACGIH's role in setting standards adopted by state governments, and eventually the federal government, enhanced that status. Second, the adoptions gave the organization influence: Firms followed its recommendations, and government agencies adopted its TLVs. Strong evidence that the organization derived some benefit from their use can be found in the fact that the organization and its members tolerated such uses over long periods, uses that directly contradicted the stated purposes of the TLVs.[287]
The ACGIH also played an important role for large firms, which, in turn, assumed key roles in creating and determining the TLVs. As one study noted, "It is easy to document the influence of industry, and of industry consultants in ACGIH,"[288] especially since unions generally did not participate in the TLV process[289] and the ACGIH developed TLVs largely in response to industry requests.[290] Large firms thus obtained standardized TLVs around which state regulations, and eventually federal regulations, coalesced, helping prevent inconsistent standards. The process gave the firms influence over both the substances included and the levels set — influence they would find much harder to exercise over government regulatory bodies. ACGIH thus played a larger part than the Baptists (to large firms' "Bootleggers") in a "Bootleggers and Baptists" regulatory coalition.[291] It was a priestly caste in a theocracy.
Moreover, the eventual expansion of the federal role in occupational health and safety was foreseeable long before 1970.[292] The role of the ACGIH TLVs was also foreseeable. One ACGIH member and government agency employee described the use of TLVs by OSHA to a researcher as follows:

I don't think it was accidental. There had been several attempts over the preceding years to promulgate an OSHAct… and it was just a question of time as to when there would be a national occupational health and safety program. The language of the OSHAct specifically provided for the Secretary of Labor to promulgate as interim or start‐up standards, national consensus standards, that had already been promulgated under certain Acts including the Walsh‐Healy Act. Now the people in the Bureau of Labor Standards who were responsible for promulgating those standards were the same people who were going to be responsible under OSHA for setting the interim standards. Many of these people were ACGIH members but that doesn't make it an ACGIH decision. These people knew what was coming down the road and that they would have a job to do. If you had that responsibility, what would you use?[293] Another factor in the expanding federal role may have been the Nixon Administration's distrust of bureaucrats relative to private enterprise. Nixon supported initiatives like environmental legislation, at least in part, for political advantage, but he also wanted to keep these initiatives carefully constrained to avoid incurring economic penalties or alienating his business supporters.[294] Adopting the consensus standards, already in use at many large businesses, both satisfied his political need to appear to be doing something and minimized the economic effects and potential decline in support from business. The expansion of ACGIH's TLVs during the 1960s, and their "inappropriate" use in state, and eventually federal, regulations, thus served the interests of the members, the organization, the large firms, and politicians.
Several factors explain the disappearance of silicosis and industrial hygiene generally from the legislative agenda until the late 1960s. First, the improvements in ventilation and other safety measures had greatly reduced dust exposures, especially outside mining. Followup studies on Vermont granite cutters in the 1950s and 1960s, for example, concluded that improved ventilation had solved the silicosis problem there. [295] The optimism expressed at the silicosis conference seemed to have been borne out.[296] Second, although some mining unions continued to push for federal studies and silicosis benefits, many unions lost interest in the issue because of their success at winning health benefits from employers.[297] The 1950s brought a "period when the issue of work and health became synonymous with health insurance packages and thirdparty coverage for the American work force. Unions bargained for financial support of welfare funds and Blue Cross or private health insurance coverage rather than for prevention of disease at the workplace."[298] Third, there were no Gauley Bridgelike figures to focus public attention on the issue. [299] The anticommunism of the 1950s and the growth of the civil rights movement in the 1960s focused public attention elsewhere.[300] Due to a lack of scientific breakthrough, vigorous efforts by interest groups, or a salient public event, little changed in regulation. When action did come with the 1970 passage of the OSH Act, it came as part of the contest between the Nixon Administration and the Democratic Party for blue collar voters.[301] Nixon had an "acute political sensitivity" and followed virtually every policy discussion with "a presidential expatiation which be[gan]: 'Now let me talk about the politics of this thing; how it will rum out in October and November; how it will translate into votes.'"[302] Labor votes were central to Nixon's plan, even if he could not completely win over its leadership.[303] Charles Colson, a key political advisor, told Nixon in 1970 that they "need[ed] to identify with labor on a major substantive issue other than national security,"[304] and OSHA provided such an issue. Nixon's view of the conservativism

of the voters he sought to woo included recognition that these voters opposed social engineering, not government programs they thought benefited them.[305] The strategy paid off in the 1970 midterm elections, with large gains in areas that had supported Wallace in 1968.[306] Senate committee hearings in 1968 and 1970 were critical in both getting issues before the public and building support for the OSH Act.[307] The creation of OSHA and NIOSH in 1970 is thus consistent with the interest group perspective.
D. Regulation Under OSHA The passage of the OSH Act dramatically changed the institutional environment, creating new incentives and interest groups and altering existing ones.
I. OSHA and Incentives There are three key features to the regulatory regime created by the OSH Act. First, the statute separated standardsetting and enforcement from the development of technical knowledge about workplace hazards, locating the former in OSHA and the latter in NIOSH.[308] This separation of standard setting and enforcement from research "has its roots in the history of earlier occupational safety and health activities and conflicts between the Department of Labor and the Public Health Service."[309] The ACGIH had to be careful in disputes over agency location in setting up OSHA because it had members in both public health and labor agencies.[310] Protecting the interests of existing bureaucracies thus explains the split between OSHA and NIOSH, a split that may have hindered OSHA's ability to set standards.[311]
Second, the statute required the agencies to act quickly to create a base of federal standards.[312] OSHA had only two years to convert existing consensus standards into legally binding ones unless the agency found that doing so would not improve safety and health.[313] This provision led to OSHA's wholesale adoption of things like the ACGIH TLVs as standards. Shortly after Congress established OSHA in 1971, the agency issued more than 4,000 general industry standards, based on national consensus standards of the American National Standards Institute and the National Fire Protection Association, as well as existing federal maritime safety standards.[314] In just four months, OSHA took more than 400 pages of standards from a variety of prior programs and voluntary organizations and converted them into regulations.[315] This change had the effect of converting a set of largely discretionary industry guidelines into mandatory workplace design standards[316] and, as noted below, changed the role of other agents in the market for health and safety.[317]
Some have criticized OSHA for not attempting to "sort through the existing standards to weed out those that were obviously silly and outdated."[318] Salter's study and Corn's institutional biography both suggest, however, that because ACGIH members in their capacity as bureaucrats were involved in the process the explanation may not lie in a lack of knowledge about whether particular provisions were "silly or outdated" but rather in a wholesale acceptance of a broader role for TLVs than had ever been officially acknowledged as a goal by ACGIH. Reinforcing this interpretation is the recollection of an ACGIH member, who described the situation to Professor Salter as follows:
At the time of OSHA's creation, there was a lot of soul searching at ACGIH. We wondered whether we should just fold up our tent and go home. There was a lot of encouragement in that direction coming from NIOSH. NIOSH felt that now it had legal responsibility for establishing criteria for standards, that ACGIH's TLV committee had done its job well, but that now we were in a new era and NIOSH superseded us. There were a lot of people at

NIOSH who felt that way and weren't afraid to express it to the TLV committee and ACGIH itself. I was on the Board of Directors, but I think even more discussion was taking place in the TLV committees. It ended up with a wait and see attitude for a couple of years. By the mid‐1970s, there was a realization that the new system was not going to be responsive to current problems.[319] Converting the TLVs into standards served the interests of the ACGIH by giving it a rationale for continuing its work and served the interests of OSHA in getting regulations on the book quickly.
Moreover, OSHA standards did not come into existence in a vacuum. Before OSHA, there were state and local regulatory efforts as well as voluntary standards like the ACGIH TLVs. Large firms operating across jurisdictions benefited from nationalizing regulations, getting rid of conflicting local standards, and shifting the regulatory focus to Washington where they could afford to maintain lobbyists and lawyers. Indeed, the threat of conflicting state and local regulation remains a potent one. When the new Reagan Administration stopped work on a Carter Administration proposal for "right to know" rules, for example, unions began lobbying for state and local versions.[320] Worried about a patchwork of inconsistent rules, industries then sought federal rules that would preempt local standards.[321] Adopting the ACGIH TLVs, with which they were already familiar, gave larger firms an advantage and forced their smaller competitors to incur additional costs.
Third, after the initial wave of standards copied from elsewhere, OSHA had to use its rulemaking powers to adopt new standards or modify existing ones. The "adversarylike process" of standardsetting gives those involved an incentive to produce all available evidence in support of a desired outcome.[322] "It is precisely this process that confirms the degree of uncertainty regarding the question of what is a 'safe' level of exposure"[323] in the context of hazardous substances. Unlike the relatively informal development of ACGIH TLVs, the process of OSHA standardsetting produced more vigorous participation by unions, which had largely ignored the ACGIH process, and by OSHA employees, a new interest group established by the creation of the agency. The subsequent history of OSHA and its workplace health standards is thus consistent with the interest group analysis.
2. OSHA and Interest Groups Industrial hygienists as a group were the first major beneficiaries of the creation of OSHA and NIOSH. Passage of the OSH Act "created an intense interest in setting standards,"[324] "[j]ust as state and local industrial hygiene programs reached a low point and the profession seemed to be splintering, the federal government broadened its role in occupational safety and health."[325] The creation of NIOSH and OSHA led to "an enormous growth of professionals" in industrial hygiene: ACGIH membership boomed, and for the first time, a majority of ACGIH employees came from federal agencies.[326] Membership soared from approximately 1,000 in 1968, to over 1,500 in 1973, to almost 2,500 in 1983.[327] An organization that began in 1938 primarily consisting of 76 employees, almost all state and local agency employees, grew to 3,720 members, with a substantial federal contingent, by 1988.[328]
Creating OSHA brought an additional interest group into existence: OSHA's employees. OSHA's initial loose organizational structure gave the staff a great deal of autonomy, if not an overabundance of resources.[329]
As a result, when the Reagan Administration attempted to implement (de)regulatory agendas that were not those of the agency staff by exercising greater White House control (via the Office of Management and

Budget (OMB)) over the agency, the agency staff found itself frustrated and turned to allies on Capitol Hill. For example, at congressional hearings in 1988, OSHA staff testified about the frustration of working on standards that were ultimately rejected by the agency or when they felt professional pressures as a result of agency positions. Working at the agency was, as one scientist put it, "extremely frustrating, and you ask yourself the question why are you doing this."[330] As McGarity and Shapiro conclude from their analysis of OSHA in the 1980s,
Like any professional, an OSHA health scientist would like to believe that he or she is accomplishing something. But it is very hard to feel a sense of accomplishment when a regulation for which you are responsible sits on the desk of an upper‐level manager or an OMB desk officer for years.[331] Additional evidence of OSHA staff acting as an interest group comes from its practice in the 1970s of funding activist groups "that sought to educate workers about actions they could take in public forums to bring about safer workplaces,"[332] funding which created a demand for OSHA's services. (This funding stopped under President Reagan.)[333]
Not only was OSHA's staff now an interest group, but outside interest groups now had a potential ally. Unions in particular found OSHA — except during the Reagan and George H. W. Bush Administrations — to be a useful ally in some situations. For example, unions opposed Reagan Administration efforts to achieve voluntary compliance rather than to use large fines to motivate employers: "Workers preferred OSHA to be the 'tough cop' rather than a 'helpful consultant.'"[334]
The creation of OSHA dramatically changed the environment under which standards were created. As one observer noted,
A rule of thumb would suffice in the 1950s; it could easily be dislodged by industry and other criticism in the 1970s [under OSHA]. The expectations of the scientific basis for standards had increased considerably in the interim. More important, the relationship of industry to the standards themselves was changed by the introduction of regulatory standards and litigation arising from them.[335] In short, "[o]nce a coherent (albeit not necessarily adequate) body of regulatory standards existed, as they did after 1970, the environment for standardsetting changed. ACGIH, other standardsetting bodies and regulatory agencies were in competition."[336]
OSHA also changed the standards environment by allowing those dissatisfied with the results to seek relief from the courts and political process. This affected how OSHA created standards. Professors McGarity and Shapiro, for example, concluded that judicial review was "a primary cause" of OSHA's slowness in issuing standards: "The impact of having to dot every i and cross every t for fear of a judicial remand has had a dramatic effect on OSHA."[337] The history of OSHA's efforts to regulate "ergonomics" injuries illustrates the impact of the political process. OSHA issued its first directive on the subject of ergonomics in 1986[338] and began the rulemaking process to draft an ergonomics standard in 1992. The final Ergonomics Program Standard was not issued until November 4, 2000.[339] Despite years of development, the standard was still controversial, and Congress passed a Joint Resolution, signed by President George W. Bush, repealing it on March 20, 2001.[340] Concurrent with the rule development process, OSHA was bringing enforcement actions against employers under the "general duty" clause of the OSH Act, which imposes a general obligation on employers to protect workers from "recognized

hazards" in the workplace. Yet, in the three cases OSHA litigated to judgment, it was unable to convince the courts that (1) a recognized hazard existed, (2) workplace activity caused the injuries, or (3) OSHA offered solutions to the hazard.[341]
3. The Silica Standards How did silica fare under the new regime? OSHA's regulation of silica began with OSHA's adoption of the ACGIH consensus standard in 1970, which set maximum exposure levels at 0.10 mg/m .[342] Unfortunately that standard was obsolete by the time it was adopted. In 1968, there was a major change in how individuals estimated quartz exposures based on dust samples. This change led to the adoption of arbitrary conversion factors to account for differences between the old and new measurement standards. [343]
Also in 1970, the newly created NIOSH began a study of lower levels to understand the impact of this methodological change. The study concluded that there was a significant loss of lung function and perhaps radiographic changes at the current dust levels. This finding led NIOSH in 1974 to recommend a change to an exposure level of 0.05 mg/m . Because the epidemiological studies on which NIOSH relied were "called into question because of technical and procedural problems," the recommended exposure limit has not been accepted by the Department of Labor.[344]
In the 1980s, new studies found crystalline silica to be a potential carcinogen, triggering OSHA's Hazard Communication Standard (HCS or HazCom standards).[345] Under the HCS, OSHAregulated businesses using materials with 0.1 percent or more crystalline silica must follow federal guidelines on hazard communications and worker training.[346] HCS coverage did not immediately trigger new exposure regulations, but it did get the attention of the mining industry (which involves a great deal of silica exposure), mining regulators, and state legislatures.[347] The Mine Safety and Health Administration (MSHA) issued its own HazCom standards in 2002.[348] OSHA has issued several interpretive letters clarifying the standard with respect to silica and denying petitions for exclusions of certain silica applications from the HCS requirements.[349]
In the private sector, both the American Society for Testing and Materials (ASTM) and the Building Construction Trades Department of the AFLCIO have also developed recommended practices for protecting workers who may be exposed to quartz dust.[350]
Recently, OSHA has moved the regulation of crystalline silica to the top of its regulatory agenda. It is one of four "high priority regulations" listed in the December 2004 Regulatory Plan.[351] In October 2003, OSHA provided for review by a Small Business Advocacy Review panel a draft rule to address exposure to crystalline silica.[352] The draft included three alternative "permissible exposure limits" (PELs): the current 0.10 mg/m , 0.075 mg/m , or 0.050 mg/m , all measured as an 8hour timeweighted average (TWA) concentration of respirable crystalline silica.[353] In December 2003, the small business panel submitted a report to OSHA, commenting on OSHA's evaluation of the costs and riskreduction potential of compliance with different standards.[354] OSHA plans to complete a peer review of its health effects and risk assessment by December 2005 and to issue a proposed regulation by April 2006.[355] The MSHA has also listed silica on its regulatory calendar.[356] Noting that "the Secretary of Labor's Advisory Committee on the Elimination of Pneumoconiosis Among Coal Mine Workers made several recommendations related to reducing exposure to silica" and that "NIOSH and ACGIH recommend a 50µg/m exposure limit for respirable crystalline silica," MSHA states it "is considering several options to reduce miners' exposure to crystalline silica."[357] In its Spring 2005 agenda, MSHA proposed as its next action a "request for information" but did not establish a time table for action.[358]

The measures necessary to stop silica dust from harming people are conceptually simple[359]: reduce exposure to the dust. There are four main methods of reducing exposure to dust. First, jobs might be redesigned to eliminate exposure to dust. For example, a silica product might be replaced with a different substance in a grinding application.[360] This method has limited capacity because silica is both so common and so useful. Moreover, restructuring the workplace is exactly the situation in which Hayekian local knowledge will be most needed — making it all but impossible to impose through a centralized regulatory regime without imposing unacceptable losses. Such welfare losses from a centralized approach might be borne with respect to an infrequently used substance, both because the range of uses might be small enough to reduce the losses' magnitude and because the amount of use is small enough to reduce the total loss to a bearable level. Where a substance is used as widely as silica, however, it is not possible.
Second, engineering steps might be taken to reduce exposure.[361] For example, dust suppression equipment might be deployed[362] or increased ventilation might reduce dust concentrations.[363] These engineering steps are the primary approach taken by OSHA, both with respect to silica and other hazardous air contaminants. They have the regulatory virtue of allowing OSHA to specify a level of contamination in the air that gives the impression of precision.[364] As noted earlier, however, OSHA's current standard (in effect since 1970) is based on outdated measurement technology.[365] Most importantly, such standards provide no incentive for increasing knowledge about the regulated workplace hazard; indeed, they may even discourage it by focusing attention on compliance with the standard rather than on harm reduction. Given the costs of changing an OSHA regulation, they certainly do not encourage investigations by private parties into categorization issues.
Third, vulnerable employees may be removed from the workplace.[366] Unions have traditionally resisted this approach,[367] and OSHA has followed their lead and generally not included such provisions in its regulations. As medical knowledge increases, however, genetic links between individuals and vulnerability to particular substances are likely to emerge.[368]
Finally, workers at risk of exposure could wear personal protective equipment, but OSHA generally prefers not to use this method of controlling occupational exposure to hazardous substances. As one reference work on the subject firmly concluded: "Personal protective equipment, and in the case of dust exposure, specifically respiratory protection, should only be considered for operations where it is not possible to control exposure by other means. They should never be considered as an alternative to engineering controls."[369] Why not? Occupational disease control specialists have three main objections: (1) the gear is not "foolproof;" (2) it depends on workers' "voluntary compliance" with the program for their use, and workers will not follow instructions on using personal equipment; and (3) it requires an ongoing maintenance program.[370] The first and third of these are not serious objections — no method of exposure control is foolproof, and all equipment requires maintenance.[371] The problematic objection is thus that workers will not properly use the equipment intended to protect them. This objection has a long history.[372] In essence, it amounts to a claim that workers make inappropriate tradeoffs of immediate comfort and longterm health (by removing uncomfortable respirators) and/or do not properly understand the risks posed by the substances from which the respirators are intended to protect them.[373]
So long as occupational health regulations forbid reliance on respirators, of course, the incentive to develop more effective, lower cost, and more comfortable equipment is eliminated. We observe a quite different rate of technical progress in other, similar areas of equipment. Scuba gear, for example, has progressed from heavy, relatively failureprone, surplus military gear to lightweight, ergonomic, comfortable, failsafe, consumerfriendly gear. As a result, scuba gear is in widespread use in environments where the potential for immediate injury and death from equipment failure is more severe

than that found in most workplaces. Again, we see the influence of regulation distorting the development of new knowledge that could provide superior protection for employees because of institutional biases.
E. Explaining Regulations There are a number of reasons why regulating silica ought to be a reasonably easy matter. A hazardous substance, visible to the naked eye, with a documented history of causing occupational disease problems should be a straightforward case for regulators. Indeed, some optimistic sources have even suggested that silicosis can be prevented entirely by proper regulation.[374] When the IARC identified silica as a "probable human carcinogen," regulating it should have been straightforward — standards needed to be tightened in light of the newly recognized risk. What to do to prevent silica exposure also ought to be clear. The general principle in occupational disease prevention is to prevent exposure.[375] Preventing dust exposure is neither difficult nor novel; prevention requires a combination of ventilation and dust reduction or removal.[376]
Unfortunately, regulating silica is not straightforward.[377] Relatively obvious problems include the presence of other minerals in dusts, which make interpreting data about exposures more difficult.[378] Equipment and techniques may not be competent to undertake the task of measuring at levels required by regulations.[379] Health and exposure records are incomplete, causing difficulties in linking individuals' conditions with workplace exposures and thereby complicating efforts at setting exposure levels.[380] There are also more complex problems related to the particular form of silica dust to which individuals are exposed.[381]
Moreover, there are serious problems in identifying the cause of lung damage from silica exposure. The successful effort to reduce exposures itself complicates attempts to identify the remaining harms by eliminating the most obvious evidence of exposure and making the health effects harder to spot.[382] Indeed, even with asbestos, where lung damage was (at least theoretically) more readily identifiable, there have been serious problems linking harm to the inhaled dust. For example, as part of the Manville Trust's distribution of funds to asbestos claimants, the Trust implemented an audit program. Using only personnel selected in consultation with the plaintiffs' bar, none of whom had ever testified on behalf of a defendant in an asbestos case, and a liberal rule for inclusion of claims,[383] the audit nonetheless discovered that approximately half of the claimants' radiographs had no indication of "even lowlevel, subdiagnostic Xray evidence of interstitial fibrosis."[384]
Because of the difficulties in developing adequate exposure and health records, data availability often drives regulations. In the case of silica, for example, the two primary sets of health data come from a series of studies of Vermont granite workers[385] and white South African gold miners.[386] Indeed, the history of medical knowledge about silicosis comes primarily from studies of individuals who had extraordinarily high levels of exposure, such as Nevada mill workers, Vermont granite cutters, and the workers at the Gauley Bridge, West Virginia tunnel incident.[387]
The highest quality medical evidence, therefore, comes from extremely limited sources. Given the variability in types of silica, we therefore confront the problem of how to account for this limitation. Consider, for example, the Vermont granite cutters. The Vermont studies came about because of an increase in silicadustrelated tuberculosis in Vermont after the introduction in 1900 of pneumatic chisels and surfacing machines.[388] The high degree of variance in exposure across job categories enabled creation of a doseresponse relationship for granite dust.[389] The state then conducted followup studies through 1965, which "determined that no cases of silicosis had appeared in workers first employed after 1938."[390]

There are not only the usual doseresponse questions about extrapolating from highexposure studies to low exposures, but the granite workers were exposed to silica of particular types, which may or may not be representative of silica found elsewhere.[391] To use the language of our earlier hypothetical, we thus do not know whether the Vermont studies concerned αkryptonite or βkryptonite. Moreover, the Vermont granite cutters were exposed to freshly cut silica, and some silica exposures today are to aged silica. Again, turning to our earlier hypothetical's language, we must decide if the distinction between αkryptonite and α'kryptonite is relevant as well.
But, these are not merely hypothetical discussions. Scientists working for the Sorptive Minerals Institute have obtained samples of the ore used in the study of South African miners and examined the form of silica present.[392] They determined that there is a difference between it and the aged silica present in many absorbent products manufactured with mined silica and related minerals. What are regulators to make of such evidence? If the South African studies are the basis for a new regulatory effort, are firms using noncomparable forms of silica to be exempted from the new regulation? Or must they undertake the far more complex and likely impossible task of proving that the distinction renders their materials "safe"?
In addition to the chemical, biological, mineral, or other characterization of the regulated substance, technological change also plays a critical role in regulation by providing more sophisticated measurement techniques. Our ability to measure dust levels today, for example, is far more sophisticated than even thirty years ago. Further, our ability to diagnose health effects has taken a major step forward with the development of CT scan technology, which reveal even smaller impacts on lungs, raising important questions about a number of aspects of regulation:
The large increase in sensitivity afforded by CT scans raises the question of whether tiny opacities, hitherto not discernible on plain chest radiographs, will become the standard for making the diagnosis of work‐related lung disease. The implications are manifold, including the question of whether future radiographie surveys of industries should include CT, whether the more sensitive detection of abnormalities will be important in litigation or disability evaluations, and whether arguments can be made that at least part of the responsibility for these changes rests with the general exposure to environmental particles, and is not therefore strictly related to employment.[393] The future development of institutions dealing with occupational hazards such as silica exposure need to take into account these uncertainties and technologies. These developments will increase both the fineness with which we can distinguish one form of a potentially harmful substance from another and advance the point at which we can identify small changes in human health from exposures. It is also virtually certain that these advances will occur faster than we can link the distinctions to the health effects, increasing the problem of categorization for future regulators.
Because individuals staff OSHA, its regulations reflect their motives and selfinterest. Being selfinterested does not mean that bureaucrats do not have altruistic goals; rather, it means that even publicspirited OSHA staff are motivated by a desire to maximize what they think is the public good. This innate bias may not always coincide with others' views of the public good. In addition, they may have other motives:

Bureaucrats normally have several private motives. One is, of course, simply not to work too hard…. Another is to expand the size of one's own department and in the process of so doing, being willing to go along with the expansion of all the rest. A third is to improve the "perks" that accompany the particular position….[394] In general, bureaucrats have incentives to call for additional regulations and spending in support of the interests that justify their programs' existences.[395]
OSHA has had less success at expanding its authority and resources compared to many other regulatory agencies. Although staffing and spending to develop, administer, and enforce OSHA regulations have generally been increasing in real terms since Congress established the agency in 1970,[396] OSHA's growth has been less rapid than the growth of other agencies, particularly the Environmental Protection Agency (EPA) and, more recently, the Department of Homeland Security.[397] OSHA also lags behind other agencies in regulatory volume: OSHA generally issues far fewer regulations than does the EPA. In 2004, for example, OSHA issued (in proposed or final form) nine regulations, only one of which was considered economically significant,[398] compared to the EPA's 65 proposed or final regulations, 11 of which were economically significant.[399] In the first four years of the Bush Administration, OSHA issued three final economically significant regulations. Similarly, during the previous eight years of the Clinton Administration, OSHA issued only seven economically significant rules — less than one per year.[400]
Despite its relative inactivity, OSHA promulgates regulations that are costly for the economy. According to recent estimates, OSH Act regulations constitute nearly onehalf of the total direct cost of workplace regulations — around $41 billion per year in 2000.[401] MSHA regulations cost another $7.4 billion.[402] It is unclear whether these costs produce commensurate benefits. Econometric studies have generally failed to find evidence that OSHA regulations have had a significant impact on job safety.[403]
What explains OSHA's relative lack of success at gaining resources and authority? Three important factors stand out. First, the primary outside interest group behind OSHA regulation is organized labor. Unions generally support OSHA regulations for three reasons: (1) the regulations raise costs for both union and nonunion employers, evening the playing field; (2) the regulations give unions a tool to use in negotiations (OSHA complaints by union members can reduce productivity); and (3) the regulations, through their participation in the regulatory process, give organized employees a comparatively greater voice in workplace organization than unorganized employees, thus providing a benefit to employees who join unions.[404] Others interested in expanding state power also find the issue attractive.[405] Since 1970, union political power has declined, as union membership has fallen from 24 percent of the private labor force in 1973 to less than eight percent in 2004.[406] Moreover, since 1970, Republicans, generally unsympathetic to unions, have controlled the executive branch for 24 of the past 36 years. Even the 12 years of Democratic control came under Presidents Carter and Clinton, both of whom may be described as less than sympathetic to unions and arose from the more conservative wing of the Democratic Party. OSHA thus has lacked an effective outside ally in seeking to expand its authority and resources.
Second, OSHA lacks the political capital of other regulatory agencies. Early missteps, particularly connected to its transformation of voluntary consensus standards into mandatory regulatory standards, gave the agency a bad reputation both on Capitol Hill and among the public. The lack of highly publicized events that spur public demand for regulation also hampers the agency's quest for additional resources and authority. Compare OSHA's record to the creation of state and federal programs for black lung, a disease among coal miners similar to silicosis. Like silicosis, diagnosis of black lung was highly controversial. Miners pointed to the high levels of dust visible in mines; mine owners and many medical

professionals insisted on objectively verifiable diagnoses, such as radiographie evidence.[407] Not until the combination of several unrelated historical events — industry conditions that weakened the union Welfare and Retirement Fund's finances, the rise of a dissident United Mine Workers group that seized on the black lung issue as a vehicle for challenging the established union leadership, and a disastrous mine explosion attributed to high dust levels — however, did a coalition capable of obtaining regulatory action coalesce.[408] The result was both state and federal legislation. As two prominent commentators have noted, "What appeared to be radical demands of a vocal minority [of miners] became Federal policy because members of Congress coalesced around their interest in reelection and their need to ally with colleagues."[409]
Third, OSHA regulations greatly affect the industries it regulates. The threat of OSHA regulation spurs these firms to organize collective resistance to OSHA activity. As a result, OSHA is a relatively weak institutional actor compared to other federal regulatory agencies. OSHA has been unable to expand its authority and resources as rapidly as other agencies have been able to do, in part because it has been hampered by a lack of political capital, opposed by highlymotivated interest groups, and lacking in effective outside interest group allies.[410]
Silica virtually disappeared as a subject of regulatory interest in the period between World War II and the creation of OSHA. The combination of voluntary efforts through the ACGIH TLVs and workers' compensation coverage "solved" the silicosis problem by creating a mechanism to compensate those injured that, in turn, provided employers with an incentive to improve workplace conditions (to lower premiums). The TLVs provided a benchmark, allowing employees to compare their employer's practices with an industry standard and facilitating market pressures for improving health and safety. That exposures did not continue to fall during this period may reflect the preferences of employees and employers to maintain silica dust exposure at a level above zero because the marginal cost of the reductions to zero were too high for either group to accept.
This regime appears to have been successful enough that we could drop the quotation marks from the word solved in the preceding paragraph. Silicosis declined in the United States after World War II, as best we can tell, and remained a problem primarily in a few high exposure industries.[411] The primary flaw was not employers ignoring health effects, but the flaw rested instead with unions deciding not to engage in the ACGIH process, which left it to the interests of large firms and bureaucrats. Union participation would have introduced an interest group to challenge their data and conclusions, thus improving the ACGIH process. Unions, however, had other fish to fry.
Knowledge of silica's health effects grew after World War II, largely through a combination of public and private investment. NIOSH and IARC both pulled together a great deal of research on silica, but that research came from a mixture of private, nonprofit, and publicsectorfunded researchers.[412] Postwar problems with silica stem largely from OSHA's involvement. By ossifying the ACGIH standard, OSHA eliminated the flexibility of the ACGIH process without adding any compensating benefits (such as more comprehensive analysis) to the near universal acceptance of the TLV. OSHA's failure to respond to NIOSH and IARC since NIOSH first warned of the existing standard in 1974 is a textbook example of government failure.
The inability of regulators to keep pace with the growing knowledge of silica exposure risks created an opportunity for the issue to be addressed through another venue: the courts. The role of the courts and interest groups that participate in the resulting litigation are discussed in the next Section.
III. REGULATION BY LITIGATION

In addition to the regulatory interest groups described above, there is an additional interest group that can play, and already has played, a major role in regulatory debates: the plaintiffs' bar. Suits over silicarelated diseases have a long history.[413] While workers' compensation covers occupational exposure to silica, silica's use is so widespread that suits against product manufacturers are not implausible.[414] In this Section, we consider the history of asbestos litigation as a potential model for predicting how tort law might implicitly regulate silica.
The mass ton litigation over asbestos dates to the Fifth Circuit's 1973 decision in Borel v. Fibreboard Corp. [415] In that case, the court recognized a products liability theory that enabled injured employees to avoid the exclusive remedy provisions of workers' compensation schemes and sue the manufacturers of asbestos products used in the workplace.[416] Workers' compensation systems had trouble handling occupational disease claims for diseases with long latency periods and whose cause lay in employees' exposures to multiple sources of asbestos at a variety of employers over decades.[417] Thus, allowing suits against the manufacturers of the product was an important doctrinal innovation in compensating individuals who had suffered serious harms,[418] such as mesothelioma, a form of lung cancer closely linked to asbestos exposure.[419] As one commentator noted, "Modem asbestos litigation was born when courts, having lost confidence in workers' compensation schemes, developed doctrines of products liability to provide tort remedies to injured workers as a substitute for workers' compensation benefits."[420]
Asbestos litigation soon became something quite different than what the early commentators anticipated. It is now "the longest running mass tort in U.S. history."[421] Some have compared it to "a massive, unending river,"[422] or "a malignant enterprise."[423] It has spread far beyond the original suits against the manufacturers of asbestos products to "virtually all parts of the U.S. economy,"[424] involving defendants in 75 of the 83 twodigit Standard Industrial Classification codes.[425] Its scale dwarfs even major regulatory impacts, natural disasters, and terrorist attacks; former Attorney General Griffin Bell contends that asbestos litigation's estimated costs to the economy are greater than the estimated costs of "all Superfund cleanup sites combined, Hurricane Andrew, or the September 11 terrorist attacks."[426]
Asbestos litigation's evolution is relevant because it illustrates how an interest group comes into being and influences subsequent events.[427] Indeed, some have argued that the asbestos bar is attempting to expand into silica suits, and the goal of the asbestos plaintiffs' bar is "to keep the asbestoslitigation gravy train alive."[428] The scale of asbestos litigation and the amount of money involved has continued to grow at a pace even the most pessimistic analysts did not anticipate. A RAND Corporation study of the litigation in 1983 made the "shocking" prediction that the litigation and subsequent compensation expenses would total $1 billion through 2001, with more than 21,000 lawsuits and three major corporations in Chapter 11 bankruptcy.[429] Other analysts predicted that the total costs could ultimately reach as much as $38 billion. [430]
These estimates proved wildly off the mark. By 2000, more than 600,000 people had filed claims, generally against multiple defendants,[431] over 6,000 entities had been sued,[432] and $54 billion had been spent on compensation and litigation costs.[433] Another measure of the unexpected size of awards for asbestos is the rapid exhaustion of the $5 billion Manville Trust, set up to fund payments to claimants against the Johns Manville Company; less than two years after it was created in 1988, the trust was effectively insolvent.[434] Reasonable estimates of total costs now range from $200 to $265 billion, an over fivefold increase in twenty years.[435]
Asbestos litigation has changed markedly in character as well. The litigation has spread from suits by plaintiffs who had contracted a rare form of cancer closely linked to asbestos exposure against the manufacturers of asbestos products to now "touch almost every type of economic activity in the U.S."[436]

and include plaintiffs without any symptoms. Plaintiffs with cancer no longer bring most of the claims: 65 percent of compensation has gone to nonmalignant claimants.[437] The number of defendants sued by each plaintiff soared from 20 in the 1980s to between 60 and 70 in the 1990s.[438] Asbestos litigation has grown from a problem of large asbestos manufacturers into a problem for even firms "with as few as 20 employees and just a few million dollars in annual revenues."[439] By the 1990s, "nontraditional" defendants accounted for over 60 percent of asbestos expenditures.[440] Some of these developments may have been the result of a courtimposed expansion of insurance policies to provide unlimited coverage for asbestos claims, which had the effect of making "allies" of the plaintiffs' bar and the asbestos defendants: To avoid bankruptcy, asbestos defendants agreed to mass settlements and default judgments and then made insurance claims, without subjecting the claims to a great deal of scrutiny, resulting in some meritless claims.[441]
Relatively few asbestos cases actually went to trial.[442] In the 1980s and 1990s, the litigation "matured" into quasiadministrative proceedings that handled claims in bulk.[443] As one observer has described the flood of litigation,
The leading asbestos manufacturers had been sued in tens of thousands or hundreds of thousands of cases and had evolved strategies for managing the litigation. A large fraction of the cases were being filed by a small number of plaintiff law firms. Over time, the litigation became more and more concentrated in a small number of firms. By 1992, ten firms represented half the annual filings against the defendants who provided data to us. By 1995, ten firms (many, but not all, of the same firms that had been in the 1992 'top ten') represented three‐quarters of the annual filings against these defendants, which had themselves grown by a third. The leading firms had standing settlement agreements with the major defendants. Virtually all the cases settled.[444] This process generated enormous gains for the law firms involved: The Dallas law firm Baron & Budd had reportedly grossed more than $800 million from asbestos cases by 1998.[445] Transactions costs have consumed more than half of the spending on asbestos claims, with the majority going to plaintiffs' law firms.[446] In a sign of their power, the share of spending going to plaintiffs' firms held steady, while defense firms' share fell over time (with the savings going to the plaintiffs).[447] In the case of the Manville Trust, in which the claims "were paid out under a bankruptcy plan which was largely designed by plaintiff lawyers," plaintiffs' claims "generated approximately $250 million in fees at an effective hourly rate of $5,000 per hour for largely administrative claiming."[448]
The process created a powerful economic interest: the asbestos plaintiffs' bar.[449] Ralph Nader, lauding their efforts, noted, "Personal injury lawyers must know that they could soon be defeated as a group precisely because of the corporate reaction to their judicial successes as individuals. Defeated, that is, unless they organize as a group to preserve and expand the emerging legal order regarding the area of toxic tragedies."[450] These firms, which invested considerable sums in developing expertise in asbestos related matters, will naturally seek to increase the return on their investment by expanding the range of claims, claimants, and defendants.[451] This dynamic can be seen in the expansion of claims to include nonmalignancy and asymptomatic claims,[452] the aggressive search for claimants,[453] and the extraordinary expansion of defendants in asbestos litigation.[454]

Viewing the history of asbestos litigation in retrospect, it becomes clear that the plaintiffs' bar had an incentive to invest in developing evidence[455] and legal theories,[456] since both could be used in multiple cases. They had the incentive to search for the most favorable jurisdictions for asbestos suits[457] and for jurisdictions with rules that eased procedural problems[458] — exactly what we have observed. During the 1990s, asbestos cases migrated to Mississippi, New York, West Virginia, Ohio, and Texas from California, New Jersey, Pennsylvania, and Illinois, where the majority of claims had been filed in the 1970s and early 1980s. The latter group of states' market share fell from 60 percent of all cases in the period between 1970 and 1987, to seven percent between 1998 and 2000, while the former group's market share rose from nine percent to 66 percent during the same periods.[459]
The sheer volume of asbestos litigation gives the plaintiffs' bar several significant advantages. First, by overwhelming the courts, plaintiffs' attorneys are freed from the close supervision of their fees and settlement practices, which are normally available to courts to control potentially abusive practices.[460] As Seventh Circuit Judge Richard Posner noted, the volume "exert[ed] a wellnigh irresistible pressure to bend the normal rules."[461] Second, the volume creates a demand by the courts for innovative means of processing cases to reduce costs. The lower "price" of litigation, in turn, attracts additional cases.[462] Third, the defense bar is unable to adopt vigorous defense strategies because it is overwhelmed. Fourth, the small number of major asbestos firms on the plaintiffs' side of the litigation have acquired an enormous amount of resources, which can be deployed to influence courts and legislators to protect the gravy train. [463] Fifth, because of the massive numbers and indefinite nature of many of the claims, individual plaintiffs have little control over their attorneys.[464]Finally, "[i]n practice … mass tort litigation is reduced to battles between repeat players who have litigated and negotiated settlements in similar cases many times in the past."[465] Converting the process into a repeat player game weakened the check on plaintiffs' counsel provided by the adversarial system.[466]
The asbestos bar turned to silica cases, using some of the same techniques.[467] Perhaps because they learned from the asbestos experience, silica defendants have proven more resistant.[468] In early 2005, the asbestoslike approach of several prominent plaintiffs' firms ran into trouble in a multidistrict litigation proceeding in front of a medically sophisticated federal district court judge, Judge Janis Graham Jack.[469]
In the course of resolving pretrial motions, Judge Jack uncovered a pattern of improper diagnoses of silicosis based on inadequate medical evidence. Among the problems were multiple plaintiffs diagnosed with both silicosis and asbestosis (sometimes by the same physician, in different cases),[470] rapid diagnosis (measured in minutes) and radiograph readings,[471] failure to follow the doctor's own procedures as documented in academic writings authored by the doctor,[472] and improper financial incentives (doctors and screening companies paid only for positive diagnoses).[473] Moreover, as Judge Jack noted, the pattern of silicosis claims in the 111 cases with more than 10,000 individual plaintiffs[474] before her was anomalous when population and regional variations in silica exposure were considered. [475] Moreover, the astonishing rate of silicosis in Mississippi represented by these cases attracted no press or regulatory attention.[476] The court concluded that
the clear motivation for [plaintiff's attorney, the O'Quinn firm's] micromanagement of the diagnostic process was to inflate the number of Plaintiffs and claims in order to overwhelm the Defendants and the judicial system. This is apparently done in hopes of extracting mass nuisance‐value settlements because the Defendants and the judicial system are financially incapable of examining the merits of each individual claim in the usual manner. The Court finds that filing and then persisting in the prosecution of

silicosis claims while recklessly disregarding the fact that there is no reliable basis for believing that every Plaintiff has silicosis constitutes an unreasonable multiplication of the proceedings. When factoring in the obvious motivation‐overwhelming the system to prevent examination of each individual claim and to extract mass settlements‐the behavior becomes vexatious as well. Judge Jack's opinion caught the attention of members of the House Energy and Commerce Subcommittee on Oversight and Investigations, who sent letters and subpoenas to physicians and medical screening companies identified in her opinion, asking for records and information about their roles in diagnosing patients with silicosis.[478] At a March 2005 hearing, three doctors who were responsible for almost 2,000 diagnosed silicosis claims invoked their constitutional right against selfincrimination and refused to answer the Committee's questions.[479]
Although not part of the court's analysis of the validity of the expert testimony, the court did note that
[i]f searching for an explanation in the legal field, one might focus on the fact that most of the cases were filed just prior to the effective dates of a series of recent legislative "tort reform" measures in Mississippi. One might also focus on the decline in asbestosis lawsuits, leaving a network of plaintiffs' lawyers and screening companies scouting for a new means of support.[480] Seeking additional information from state health officers in 13 states with "litigation hot spots," the Congressmen expressed concern that the health benefits of screening for silicosis are undermined
when the screening process identifies serious medical conditions but the medical professionals involved disavow responsibility for informing the patient of the finding, explaining its significance, and discussing follow‐up and treatment options. It is hard to imagine circumstances where leaving such tasks to lawyers could be considered acceptable medical practice or serving the interests of public health. The health benefit of even a competent screening may well be negated by the lack of medical follow‐up.[481] Thus, while a common law approach to problems like silica or asbestos exposure, when injured parties can claim compensation from responsible parties, might appear to provide incentives for optimal efforts to reduce exposures, the history of asbestos litigation and this initial foray into silica litigation suggest otherwise. The court system does not appear to be the best way to ensure that silica exposure is neither over nor underregulated.
IV. WHAT TO Do? If we step back and take a long view of the history of silica in the workplace and workplace hazards more generally, we can see a pattern emerge. Governments pay attention only when events facilitate the formation of a coalition seeking action. At the turn of the twentieth century, the growth of tort suits spurred both employers and employees to seek a compromise in the form of workers' compensation legislation, initially dealing only with accidents — the issue of greatest public appeal. Although the same technological change that increased accident rates also increased silica exposures, silica and dust diseases did not become an issue until the liability crisis of the 1930s. Even accounting for the lag due to silicosis's long latency period, the timing of that crisis appears more related to the onset of the Depression than to any actual increase in silicosis. Again, employers and employees compromised, extending the workers' compensation system to cover at least some industrial diseases, including silicosis. The issue again

slipped off the regulatory radar screen, emerging again only with the beginnings of the postasbestos wave of silicosis suits in this century.
The regulatory history of silica teaches three important lessons. First, the most compelling account of the cycle of action and inaction on the part of regulators is the one based on interest groups. Second, knowledge about hazards is endogenous — it arises in response to outside events, regulations, and interest groups. Accepting particular states of knowledge as definitive is thus a mistake, as is failing to consider the incentives for knowledge production created by regulatory measures. Third, the rise of the trial bar as an interest group and the asbestos litigation experience means that the problems of silica exposure and similar occupational hazards cannot simply be left to the current legal system for resolution through individual action.
Many OSHAreform proposals focus on unblocking OSHA's regulatory process and speeding up the issuance of new standards.[482] Our account suggests that regulatory speed and volume are not the only problems that need to be addressed. A faster OSHA that did not accurately identify the substances that cause harm would simply be imposing costs more quickly.
We suggest a threepronged approach to silica and occupational health issues generally. First, before issuing new regulations, OSHA should clearly define what market failures, if any, impede efficient solutions to address health risks. Both employers and employees have incentives to protect health and safety in the workplace.[483] The lack of information, particularly due to the long latency period for silicosis and lung cancer, may dampen these incentives. If the problem is a lack of information on risks and remedies, OSHA and its research counterpart NIOSH should focus on generating and dispersing better information. Although occupational health is not a field in which market forces are trusted,[484] the serious problems with the current system cannot be solved without recognition of the important role played by the Hayekian knowledge problem.
The federal government can play two important roles in this information market place. It can be a supplier. Through entities like NIOSH, the government can sponsor and conduct research that will influence standards. It can also be a consumer. Just as it did under the WalshHealey Act before OSHA's creation in 1970,[485] the government can demand that its information suppliers meet standards the government believes are effective.
Second, any regulatory action must recognize the diversity in exposure and response across the varied workplaces. Given the varying forms of silica to which workers may be exposed, and the problems of characterizing those forms and their associated health risk, a uniform national standard would unlikely be optimal in all situations. Heeding the lessons we have learned from the history of silica in the workplace, it is important to contrast the interest group incentives provided by a regulatory effort aimed at developing a uniform standard with those of a policy aimed at generating and disseminating information. The uniform standard provides incentives to interest groups to invest resources in influencing the standard to suit private goals (for example, gain advantage over competitors). In contrast, a focus on information provides incentives for interest groups to compete to develop and provide better information in support of their views of the risks and remedies.
The "market" for standards that existed before OSHA consisted of groups like the ACGIH, unions, trade associations, and others.[486] NIOSH's entry into this market changed the dynamics, primarily because of the influence of NIOSH criteria documents in initiating OSHA standards. Encouraging the development of competing standards for occupational health would create market pressure for increasing knowledge about harms. If a standardsetting organization could identify a distinction like the α / β kryptonite example discussed earlier and show that the distinction mattered, it could issue a more effective and less costly

standard. Competitive standards have operated successfully in a number of areas, including organic food certification and kosher labeling,[487] and have successfully improved quality in a number of areas.[488]
In contrast to flexible standards that respond to different information, a uniform standard proves hard to adjust as new information becomes available, as is evidenced by the current OSHA exposure limit of 0.10 mg/m³.[489] Knowledge is dynamic, and uniform standards necessarily lock in expectations based on the level of knowledge available at a given time. In particular, regulations that specify which remedies are acceptable or unacceptable discourage innovation into better solutions.[490]
Finally, the tort system needs to be controlled. Judge Jack's efforts are a good start, but adequate legal process must depend on more than the fortunate accident of the judge in charge of mass tort litigation having a medical background. We do not pretend to know the answers to the many questions raised by tort reform, from federalism to feeshifting, but we contend that the asbestos experience makes clear the inadequacy of modern tort law to the task of providing appropriate incentives for industrial health. Defining what to regulate is critical to avoiding both over and underregulation. If the history of silica in the workplace teaches anything, it is that our knowledge of even obvious hazards is highly dependent on medical knowledge, available technology, and a host of other factors. Increasing that knowledge depends on the incentives for knowledge creation. Unfortunately, locking current knowledge into a regulation does not provide adequate incentives for improving understanding of workplace hazards. Marketbased methods create superior incentives to develop knowledge about what is regulated, a powerful tool for improving the quality of regulatory efforts.

Graham notes that people who experience "dusty non occupational exposures, as in villages in the high Himalayas or in desert communities," also show abnormal chest radiographs and other indications of silica exposure and that even workers in very low exposure jobs also show abnormalities in cells and proteins: Whether these findings represent the presence of a disease process (alveolitis) is almost a subject for philosophical discussion, akin to asking whether tanning of the skin is a pathologic process or a normal response to an imposed stimulus. This analogy is not too far‐fetched, since exposure to both quartz and sunlight have been constant companions in the evolution of biologic systems. Id.; see also Meilin Wang & Daniel E. Banks, Airways Obstruction and Occupational Inorganic Dust Exposure, in OCCUPATIONAL LUNG DISEASE, supra note 5, at 69, 69 (noting that "Chronic obstructive pulmonary disease (COPD)" is a "physiologic parameter rather than an etiologically defined disease" and so "the cause explaining these abnormal pulmonary parameters in any single individual cannot be made without a clinical evaluation").

The crystallinity of silica from different deposits, even from slightly different locations within the same deposits is not necessarily the same. This raises two problems. First, a single standard (that is, the reference material to which the silica in the sample is compared) may not be appropriate. Using a standard that matches the particle size and crystallinity of the silica in the sample is essential for an accurate analysis. Second, obtaining a representative sample, when the sample size is so small and the deposit is so large, is nearly impossible. Id.; see also John E. Craighead, Inorganic Mineral Particulates in the Lung, in HANDBOOK OF HAZARDOUS MATERIALS, supra note 5, at 399, 405 ("[T]he SiO cristobalite is far more toxic and pathogenic than the mineralogically similar alpha quartz…. Since different dusts cause disease by differing pathogenetic mechanisms, the issues are exceptionally complex."); Absher, supra note 13, at 663 ("Factors which determine whether an exposed individual develops pulmonary pathology include the dose and duration of exposure, the nature of the dust (quartz, cristobalite, or a variety of silicates and silica bearing minerals) and the content of crystalline silica in the exposure material.").

The general nature of the problem can be seen by examining the attempts to define the term "hedge fund," about which one author recently commented, "[t]o oversimplify slightly, a hedge fund is like a mutual fund that has been designed to avoid four federal laws that generally require investment funds and their advisers to identify fund officers and holdings and to submit to Securities and Exchange Commission oversight."

If αkryptonite is uniformly distributed in kryptonite, a regulation that does not distinguish the two forms may not overregulate since the amount of αkryptonite is simply a fixed percentage of the amount of the total kryptonite. So long as the regulation takes into account that the exposures should be based on the impact of the proportion that is αkryptonite, a regulation that docs not distinguish between the two forms will not overregulate. 22. Remember, we specified that we do not know if βkryptonite is harmful. We nonetheless call regulation of βkryptonite overregulation because the justification of regulation rests on the studies linking the harm to αkryptonite. 23.

disagree with their analysis of the regulatory incentive structure, their arguments are compatible with ours in some respects. Most importantly, even under Bagley and Revesz's analysis, it will be important to define the subject of regulation, and agency decisions on that point will be subject to political pressures. 69. See generally McGARITY & SHAPIRO, supra note 50 (providing an example of this lack of consideration of interest groups in a thorough account of OSHA's development through 1990). Although Professors McGarity and Shapiro are keenly attuned to the interests of businesses seeking particular actions from OSHA, they generally do not consider any motivation beyond disinterested concern for the best interests of the public for nonprofit actors. Thus, for example, in their account of OSHA's regulation of ethylene oxide, they accept at face value the participation of the Nader organization, Public Citizen Health Research Group. See id. at 8387 (mentioning briefly the organization's petition but moving quickly to the promulgation of the ethylene oxide rule). Yet the Public Citizen Health Research Group had interests beyond seeking to implement its vision of the public good. For example, the group needed to be able to raise money to support its activities. Similarly, McGarity and Shapiro accept the claims of OSHA employees who resigned during the Reagan Administration that they resigned because political interference from the Administration was keeping the agency from sound science. Id. at 9293. An alternative hypothesis is that these OSHA employees disagreed with the changes in policy instituted by the Reagan Administration and sought to use their departures to embarrass the Administration.

years). General knowledge of dusts as a source of occupational disease was also prevalent. For example, a 1902 address on "the Dust Problem" to a Sanitary Congress in Manchester, England by Sir James CrichtonBrowne included the statement that '"[t]he mortality of the principal dustproducing occupations, compared with that of agriculturalists, who live and work in what is practically dustless atmosphere, is excessive to a startling degree.'" Huffman, supra note 71, at 525 (quoting Sir CrichtonBrowne's address). Similarly, an 1879 article in "Buck's Hygiene and Public Health" by Dr. Roger S. Tracy considered dust issues at length, including noting problems of chronic and progressive disease. See id. at 52728 (quoting the article and noting its detailed discussion of the symptoms of the disease). 73.

Elizabeth Fee attributes some of the growth of medical knowledge to the increased crowding in urban areas that accompanied industrialization: The [prior] belief that epidemic diseases posed only occasional threats to an otherwise healthy social order was shaken by the industrial transformation of the late nineteenth century. The burgeoning social problems of the industrial cities could not be ignored: the overwhelming influx of immigrants crowded into narrow alleys and tenement housing, the terrifying death and disease rates of working‐class slums, the total inadequacy of water supplies and sewage systems for the rapidly growing population, the spread of

endemic and epidemic diseases from the slums to the homes of the wealthy, the escalating squalor and violence of the streets. ELIZABETH FEE, DISEASE AND DISCOVERY: A HISTORY OF THE JOHNS HOPKINS SCHOOL OF HYGIENE AND PUBLIC HEALTH 191639, at 12 (1987). Solving these social problems required understanding them, thus producing a demand for medical knowledge that spilled over into industrial contexts. This resulted in a transformation in public health agencies, shifting personnel from those hired due to "patronage or political considerations" to experts, part of the general Progressive Era trend toward expert agencies. Id. at 16. Public health and medicine had direct benefits for the military, among others, allowing the construction of the Panama Canal after the defeat of yellow fever and malaria. See id. at 16 17 (touting the triumph of improved public health over the high death toll that had previously hindered completion of the Canal). These lessons were brought home and applied in the public health and industrial contexts. Id. at 1718. The resulting agencies and projects demanded trained personnel, helping to spark professional schools in the field. See id. at 18 (noting the ncwfound stress on the need for fulltime health professionals). The emphasis remained on public health rather than industrial health, however. The 1915 Manual far Health Officers, the first handbook for public health officers, devoted only four pages to industrial concerns, compared to three hundred on contagious diseases. Id. at 21. Fee suggests that the profession took a wrong turn by focusing on individual diseasecausing agents rather than larger social contexts. See id. at 2122 (decrying the lack of majority commitment to study more than just the immediate physical impact of the various "diseasecausing organisms"). However, we believe that the marginal net value from addressing individual diseases was so large that the profession's direction was more the result of picking "low hanging fruit" than simply bad intellectual choices.

See id. at 11011, 11920 (confirming the rather infrequent use of X rays throughout the technology's early existence). As Howell notes, "The mere existence of a diagnostic technology did not dictate how or where it would be used; both hospital and machine had to change before the x ray or any other machine could significantly influence hospital care."

FEE, supra note 85, at 2. As Fee notes, Before the twentieth century, there were few formal requirements for public health positions, no established career structures, no job security for public health officials, and no formalized ways of producing new knowledge. Public health positions were usually part‐time appointments at nominal salary; those who devoted much effort to public health typically did so on a voluntary basis. Id. at 9. Since industrial medicine lagged behind public health, one may fairly attribute similar characteristics to those few interested in the relationship between work and illness.

Manufacturers in New York in 1925 supported a bill to stop the "hundreds" of common law suits over silicosis because "hundreds of thousands of dollars" had already been spent by then in settlements. Id. at 50. 168. See ROSNER & MARKOWITZ, supra note 79, at 3 (stating that in 1933 "newspapers, magazines, and professional journals were filled with stories about the threat of a new scourge — silicosis — that was crippling workers in a wide variety of industries"). For example, in New York State in 1934, there were $50 million in damages claimed in silicosis suits, prompting efforts to bring the condition into the workers' compensation system. DAVIS, supra note 167, at 30; see also ROSNER & MARKOWITZ, supra note 79, at 9196 (describing the crisis in New York). In Massachusetts, the costs of covering silicosis claims required $2 per $100 of payroll fee on top of the $2.70 per $100 occupational disease rate for foundries, almost doubling the cost of the insurance.

ROSNER & MARKOWITZ, supra note 79, at 81. 174. Rosner and Markowitz's study links the rise of silicosis to a combination of factors. First, they note that from the late 1800s until the early 1900s, medical understanding of dustrelated diseases focused on tuberculosis. See id. at 1521 (describing the early struggle of the scientific community to come to an understanding about the origins of the disease). Early in the twentieth century, evidence began to emerge, first in Britain and later in the United States, that cast doubt on the bacteriological model, but the medical consensus on the bacteriological model remained.

Vito Marcantonio: His Life and Milieu, http://users.rcn.com/redpost/life.html (last visited Mar. 29, 2006). The most comprehensive biography of Marcantonio described him as "frequently the sole spokesman in Congress for America's radical left" from 1936 to 1950.

note 113, at 163 (explaining that unions used health and safety issues as bases for "quickie" strikes during periods of relatively high labor demand in 1936 and 1937). The United Mine Workers, for example, fought long and hard for the inclusion of safety provisions in union contracts and finally gained their inclusion in the Appalachian Wage Agreement of 1941. Charles Anthony Morton, The United Mine Workers and the Establishment of Coal Mine Safety Regulations 8283 (1954) (unpublished M.A. thesis, Ohio State Univ.) (on file with the Ohio State University Library). 210. The primary issue for unions in the 1930s was gaining control over the workplace. See ZIEGER, supra note 122, at 28 ("Workers in the 1930s resolved to limit managerial authority and to safeguard their standards and status with clear contractual safeguards."). 211. As Rosner and Markowitz note, It became clear that it was in the interest of a broad range of groups to try to defuse the social crisis surrounding silicosis. The insurance industry took the lead, but state government, labor unions, and the professional community all saw the social crisis of silicosis suits as a threat. It was necessary to remove the disease from the political arena and return it to the stewardship of the professionals. ROSNER & MARKOWITZ, supra note 79, at 82. 212. Id. at 107. According to an interview with Warren A. Cook, unions at this time generally did not have industrial hygienists on staff. CORN, supra note 98, at 135. 213.

See ZIEGER, supra note 122, at 45, 55 (describing the conflict between the AFL and Congress of Industrial Organizations (CIO) as they competed over membership); KENNEDY, supra note 156, at 301 03. Brinkley notes that Roosevelt vacillated over appropriate policies at this point. See BRINKLEY, supra note 164, at 8687 (illustrating some of the criticism of the President over his lack of concrete planning). Within the Administration, the period was referred to as the "struggle for a program." Id. at 97. 215. BRINKLEY, supra note 164, at 3,23. 216. See ROSNER & MARKOWITZ, supra note 79, at 133 ("The National Silicosis Conference had not resolved the silicosis issue. Rather, it had spurred the contending groups to organize nationally."). 217. See Skinner, supra note 202, at 4 (addressing Rep. Marcantonio's call for federally imposed safety standards). The threat was probably seen as significant. Roosevelt's rhetoric had taken a hard turn left in 1935, and "he now brandished the mailed fist of open political warfare" at business. KENNEDY, supra note 156, at 278. Because the main threat to Roosevelt lay to the left in 1935, his shift leftward was aimed at Father Charles Coughlin and Gerald L.K.. Smith, the successor to the assassinated Huey Long's political program. Id. at 283. Roosevelt may not have meant it, as Kennedy concludes, but his rhetoric was undoubtedly alarming at the time.

President Promises Continued Uplift of Labor Standards, WALL ST. J., Nov. 10, 1936, at 8. The first conference's industrial health committee adopted a report advocating industrial disease coverage, periodic factory inspections, NRAstyle industrial codes at the state level, ventilation standards, and a host of other measures. See U.S. Dep't of Labor, Washington Conference on Labor Legislation, February 1934, 38 MONTHLY LAB. REV. 779, 78081 (1934) (listing the various implementations recommended by the committee).

REV. 1247, 125053 (1935) (describing the additional recommendations of the second conference). The third conference initially adopted a call for a constitutional amendment authorizing federal legislation on minimum wages and "other social legislation," although the latter phrase was later deleted at the request of Secretary of Labor Perkins, who argued that it was too broad.

There is little evidence of direct personal benefit to any members of the organization or the committees — committee members were paid only their travel expenses. Id. at 44, 47. 287. TLVs for about 400 substances were incorporated into OSHA consensus standards via their earlier use under the WalshHealey Act standards, although some were "based on inadequate documentation." See CORN, supra note 98, at 91 (describing OSHA's congressional authority to bypass rulemaking procedures and establish "startup" standards). ACGIH did not attempt to stop OSHA's inappropriate use of the TLVs. See id. at 92 (clarifying that the TLVs were not meant to be standards). According to Corn, "ACGIH seemed to have mixed emotions about use of the TLVs. They wanted to contribute to the new federal effort to bring about a healthy and safe workplace, and they were proud of the TLVs. Very little discussion can be found about this issue." Id. In the one discussion recorded in the minutes, ACGIH seems to have been resigned to OSHA's inappropriate use of the TLVs. See id. (elaborating that, although the ACGIH was displeased with the Labor Department for misusing the TLVs, it felt that if the Labor Department was going to use TLVs for that purpose it might as well use ACGIH's TLVs). The board responded to a question from the floor by saying: "There is nothing in my opinion, that ACGIH can do to prevent or stop anyone, any state or federal agency, from using our ACGIH TLVs in standards."

the legislation establishing OSHA required that only consensus standards be adopted." SALTER, supra note 223, at 42. As one informant [to the study] suggested, Section 5(a) of the OSHAct mandates the Secretary of Labor to adopt, without dealing with title 5 of the Administrative Procedures Act [sic], as soon as practicable, any of the consensus standards already established in federal regulations … Some argue that the Secretary had discussions (before adopting the standards). Others argue that the adoption was automatic because the big employers were already using these standards. Id. In addition, "There was some discussion in ACGIH about whether to adopt a consensus method, but ACGIH did not do so." Id. As one person described the situation,
Stokinger saw the legislation (OSHAct) required consensus standards from that point on (for the purpose of their being adopted as OSHA regulations). So he looked around and appointed industry and union representatives on the TLV committee for the first time. I don't think this is appreciated. Stokinger was wrong, but he thought he could make the TLV committee (into) a consensus body if there were industry and union representatives. Id.
288. SALTER, supra note 223, at 59. ACGIH and its members, however, deny that they are biased toward industry. Id. (explaining that many ACGIH members view the organization as an "industry watchdog"). 289. Id. at 46 (referring to the labor industry as a "reluctant participant" in the ACGIH). Unions refused to participate in ACGIH, believing the organization was "industry dominated." MCGARITY & SHAPIRO, supra note 50, at 124. 290. See SALTER, supra note 223, at 4748 (describing generally the informal process by which the ACGIH sets priorities and develops standards). 291. The Bootleggers and Baptists theory of regulation suggests that two different groups often work together to achieve political goals. See Bruce Yandle, Bootleggers and Baptists: The Education of a Regulatory Economist, AEI J. GOV'T & SOC'Y 13 (May/June 1983), available at http://www.mercatus.org/pdf/materials/560.pdf. Like the bootleggers in the early twentiethcentury South, who benefited from laws that banned the sale of liquor on Sundays, special interests need to justify their efforts to obtain special favors with public interest stories. The Baptists, who supported the Sunday ban on moral grounds, provided that public interest support. While the Baptists vocally endorsed the ban on Sunday sales, the bootleggers worked behind the scenes and quietly rewarded the politicians with a portion of their Sunday liquor sale profits. Id. 292.

effect over the last 30 years in steadily decreasing the number of cases of silicosis." Id. "Even silicosis, formerly a matter of major concern, has to a large extent been controlled" and that social security disability figures for silicosis claims reflect "exposures that occurred many years ago, particularly in coal mining, rather than current conditions."

See CORN, supra note 98, at 44 ("Americans in the 1950s were not very interested in occupational health. Other public health problems, for example, delivery of health care, and political issues dominated their thinking."). 301. McGARITY & SHAPIRO, supra note 50, at 34 (denouncing the compromise that the final version of the OSH Act struck between Republicans and Democrats, namely that while OSHA would have the authority to set the standards, another agency, the Occupational Safety and Health Review Commission, would be the adjudicatory body to determine whether the Act had been violated). Nixon sought an electoral realignment. See ROBHRT MASON, RICHARD NIXON AND THE QUEST FOR A NEW MAJORITY 3 (2004) (describing Nixon's immediate goal of securing a large majority for reelection in 1972). Nixon had beaten Hubert H. Humphrey in 1968 by only 500,000 votes out of 72 million votes cast, an election in which unions had worked vigorously for Humphrey. See ZIEGER, supra note 122, at 18283 (marking the 1968 presidential election as "the end of the New Deal dispensation"). Nixon was aware after the 1968 election that he "had not yet won over any majority" and that "he owed his election to the votes of a minority rallied in opposition to the mistakes of the Democrats rather than in support of his promise." MASON, supra note 301, at 37. The closeness of the election undoubtedly had turned in part on active union support for Humphrey. The AFLCIO "financed a strong operation to turn the labor vote from Wallace back to the Democrats." BLUM, supra note 294, at 314. Although Zieger terms Nixon "one of labor's chief nemeses, dating from his redbaiting campaigns for the U.S. Congress and Senate in 1946 and 1950," he also notes that Nixon had "cultivated some elements of the labor movement — hard core conservative construction unions, for example, and a huge Teamsters' union by now almost completely isolated from and disdainful of the AFLCIO." ZIEGER, supra note 122, at 191. The 1968 election results demonstrated two key facts. First, "[t]he Johnson coalition of 1964 splintered in 1968," with George Wallace's thirdparty candidacy pulling significant blue collar support in North central states (Ohio, Michigan, Indiana, and Illinois). BLUM, supra note 294, at 316. Looking to 1972, Nixon could thus hope to improve his margins among these voters. Second, Nixon had to find new support to win reelection. See MASON, supra note 301, at 6 (detailing Nixon's efforts to find this new support through refusing to oppose the notion of governmental activism, which was popular at the time, and through leaving intact a majority of the programs created by Democrats between the 1930s and the 1960s). There was no guarantee that the crisis within the Democratic Party, which played to Nixon's advantage in 1968, would continue into the 1970s. See id. at 36 (referring to Nixon's reliance on the crisis within the Democratic Party as a "fragile basis for political success"). 302. MASON, supra note 301, at 42 (quoting Elizabeth Drew). 303. See id. at 72, 9798 (noting how central the labor vote had been to the Democrats and how Nixon urged his staff to publicize his Administration as "proworkingman"). A memo by Pat Buchanan analyzing political strategy noted that the target constituency in 1970 would be "law and order Democrats, conservatives on the 'Social Issue,' but 'progressive' on domestic issues." Id. at 84. In pursuit of labor, Nixon "enthusiastically cultivated" union leaders, hosting a "highprofile" Labor Day dinner for union leaders in 1970.

labor was becoming increasingly dissociated from the Democrat Party). Nixon did persuade AFLCIO head George Meany to remain neutral in 1972. See id. at 173. 304. Id. at 97. The White House "avoided active conflict with unions on [economic issues] wherever possible." Id. at 134. 305. See id. at 49 (discussing how Nixon could reach the conservative "emerging majority"). When Nixon arrived in the White House it was "a time when mainstream political debate remained dominated by activist and not conservative proposals. … As Leonard Garment would note in 1971, in spite of their 'conservative philosophy,' Americans wanted 'liberal' benefits — complete health care, more social security, etc." Id. at 56. 306. See id. at 67 (observing that these gains were due largely to the Republicans' emphasis on the needs of the "silent majority"). It also paid off in 1972, with Nixon winning 57% of union household voters. See id. at 189 (noting that Nixon's efforts to generate support resulted in him receiving the greatest plurality in American history in the 1972 election). 307. See CORN, supra note 98, at 86 (asserting that, although the causal relationship between occupational disease and certain industries had been established, the available knowledge to remedy this problem had not been applied to preventing the problem). 308. Under the OSH Act, when NIOSH recommends that OSHA promulgate a health standard, the Secretary of Labor must, within 60 days after receipt thereof, refer such recommendation to an advisory committee pursuant to this paragraph, or publish such as a proposed rule pursuant to paragraph (2), or publish in the Federal Register his determination not to do so, and his reasons therefor. The Secretary shall be required to request the recommendations of an advisory committee appointed under section 812(c) of this title if the rule to be promulgated is, in the discretion of the Secretary which shall be final, new in effect or application and has significant economic impact. 30 U.S.C. § 811(a)(1)(2000). 309.

See, e.g., GAO, supra note 16, at 5660 (criticizing the lack of cooperation in 1970s). 312. This was supplemented by a general duty provision. The OSH Act established a general duty on the part of employers to "furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees; and [to] comply with occupational safety and health standards promulgated under this chapter." 29 U.S.C. § 654(a)(1)(2) (2000). 313.

McGarity and Shapiro describe the first decade as follows: In its early years [until 1981], OSHA had in fact been a very loosely run organization. Rulemaking initiatives were generated internally in an ad hoc fashion. The heads of the Health and Safety Directorates had traditionally controlled standard‐setting within their functional bailiwicks, with sporadic input from the assistant secretary. Loose internal work groups were assembled to draft rulemaking documents with substantial technical help from outside consultants. It was not uncommon for the head of a directorate to work directly on the rule, even to the point of typing the final version of the rule at 4 a.m. on the morning it was due. The entire agency tended to gear up for a single rulemaking effort, putting aside most other initiatives until they assumed front burner status. Id. 330. Id. at 133 (quoting Dr. Peter Infante, who discussed difficulties with OSHA administrators). 331. Id. at 134. 332. Id. at 79. 333. See id. (explaining the history of the program). 334. Id. at 143. Consider also the example of the "lockout" rule — the rule that specified procedures under which equipment is locked to prevent injury from accidental restarts during servicing — that McGarity and Shapiro use to illustrate the delays in OSHA's accomplishing even relatively straightforward rulemaking. Id. at 11214. OSHA promulgated consensus standards in 1971, but these "were not uniform in their coverage and contained significant inconsistencies between industries and between different types of equipment in the same industry." Id. at 112. The United Auto Workers repeatedly petitioned OSHA for a revised, more uniform rule, but internal debates within OSHA and between OSHA and the Office of Management and Budget (OMB) delayed a final rule until 1988, more than ten years after OSHA's initial publication of a notice in the Federal Register that it was considering revising the consensus standard. Id. at 11213. Unions did not like the final rule, primarily because it did not "incorporate the principle of 'one person, one lock, one key,' under which the worker servicing the machine must personally lock the

machine's switch in the off position before beginning the maintenance work and must personally remove the lock on the way out." Id. at 113. Unions also wanted a broader rule, applicable to more industries, and "employee participation in the formulation of lockout/tagout procedures and training programs." Id. The unions' interest in these three areas is straightforward. Both the "one person, one lock, one key" principle and the greater employee participation in creating training programs increased employee control over work procedures, enhancing union control when collective bargaining agreements existed. Expanding the application of a single rule across more industries, rather than taking OSHA's preferred industryby industry approach, favored unions, whose national office could analyze the single rule, at the expense of industries that might benefit from the casebycase approach. As this example suggests, OSHA became a political prize, since it could be used to assist or hinder union efforts in the workplace. 335. SALTER, supra note 223, at 6364. 336. Id. at 64. 337.

that would release the respirable fraction, the potential for exposure to respirable crystalline silica is remote, and the miners are not potentially exposed to a hazard. If you must remove the floor through grinding, cutting, or crushing, the potential for exposure is foreseeable and the concrete would become a hazardous chemical subject to HazCom.

(detailing the ability of local ventilation systems to trap a contaminant before it reaches the general air flow). 364. Corn details one of the key problems with using the TLVs as standards by using the following example: TLV standards were intended to be room air levels, but OSHA treated them as measurements "at the nose." See Interview with Leonard J. Goldwater, in CORN, supra note 98, at 14546. As Columbia Medical School Professor and longtime ACGIH member Dr. Leonard Goldwater explained in an interview, TLVs were based on room monitoring, not personal monitoring: Now we're doing almost entirely personal monitoring. And the values you get from personal monitoring, as you well know, have no connection whatsoever to general room air levels. I shouldn't say no connection, but they can be very far apart. In fact my experience with personal monitoring is that it gives higher levels than those in general room air. We've done some studies on this. Mercury in particular is two or three times higher at the nose than it is 6 feet away in the general room air. Now, as far as I'm aware, nothing has been done to point out the fact that these original correlations no longer hold. And that what the agencies are doing now is saying that you mustn't have more than, let's say, 10 parts per million at the nose when originally it was 10 parts per million in the general room air. You're dealing with a totally different system. And so they're insisting on the values of personal monitoring being the same as those of the general room air, which means that you have to reduce them by several‐fold. I wrote to Elkins and Stockinger about this at the time I became aware of it. And Elkins said 'You're right'; he was on the committee. And that's where that ended. Stockinger as usual giggled …. OSHA misapplied these things from day one. As far as I'm aware, ACGIH has done nothing to tell OSHA: "You're off‐base, you don't know what you are talking about. You're misapplying TLVs, you're misinterpreting them, you're doing everything wrong with them." To me this has done great mischief, to put it mildly. Id. 365.

370. See Philip Harber, Respirators, in ENVIRONMENTAL & OCCUPATIONAL MEDICINE 1757, 1757 (William N. Rom ed., 3d ed. 1998). Harber stated, Use of respirators is not the method of choice for controlling exposures. Respirators do not provide foolproof protection. Respirator‐based protection is completely dependent on voluntary compliance by the worker. Furthermore, protection by respirator use requires an ongoing multifaceted program to assure proper maintenance and utilization. The cost of the respirator itself is only a small part of the total cost of an effective program. Id.
371. The intent behind these objections may be to argue that respirators have a higher failure rate than engineering controls or that respirator maintenance is more costly or difficult than engineering control maintenance. If that were true, however, the claim would not be stated categorically, since it would have to be evaluated on a case by case basis. 372. See, e.g., ROSEN, supra note 71, at 422. Rosen offered an early historical example of the problem of worker interference with safety measures: It has been mentioned that several authors suggested the use of respirators to prevent the inhalation of dust. However, such devices did not come into common use and Federath writing in 1899 offers some illuminating information on this subject. "At the end of the seventies," he says, "I recommended the wearing of a respirator while at work as a prophylactic measure. The miners complained, however, that they could not work with it because it interfered with their breathing. I then suggested to them at least to tie a piece of cloth in front of the nose and mouth‐even in this way a large quantity of dust would be prevented from entering the lungs. I do not know whether they followed this advice — even this measure was probably too inconvenient for them. Unfortunately most of them are very indolent — the younger ones say 'we don't need that' and the older ones, 'that can't help us any more.'" Id.
373. See, e.g., Banks, supra note 71, at 4. Banks illuminated upon the difficulty in getting workers to comply with safety measures:
Conveying the public health perspective that dust‐related diseases are dangerous to a worker's respiratory health can be difficult, particularly when the period from first exposure to the development of disease may be 20 or more years. Furthermore, the frequently suggested solution of wearing personal respiratory protective devices throughout the workday is an unrealistic expectation. The increase in the work of breathing, the discomfort, the poor‐fit sometimes attributable to facial hair, and the inability to speak and adequately

communicate with one's fellow workers is almost too much too [sic] ask of any worker. Id.
374. See, e.g., Balaan & Banks, supra note 71, at 446. Balaan and Banks displayed their optimism in addressing the problem posed by silica:
Silicosis is preventable. The extent to which this can be realized depends on education of employers and employees, strict enforcement of industrial hygiene practices, and vigilance for circumstances where unacceptable exposures to respirable silica may happen. Further research on the mechanism of lung injury in silicosis and its modulation by pharmacologic agents will contribute to our therapeutic armamentarium for this disease. Id.; see also Gary R. Epler, Clinical Overview of Occupational Lung Disease, 30 THE RADIOLOGICAL CLINICS OF N. AM.: OCCUPATIONAL LUNG DISEASE 1121, 1127 (1992) (maintaining that "[v]igorous adherence to dust control regulations and dust count monitoring can eliminate this disorder [chronic silicosis]").

See Hoffman, supra note 71, at 536 (considering the dust safety techniques known in the early 1900s); CHERNIACK, supra note 71, at 38 (highlighting that "[t]he efficacy of preventative measures had also been documented" by 1915). 377.

Graham commented on the added complications caused by incomplete data: Setting [occupational exposure] guidelines is hardly a simple task, depending as they do on animal toxicology as well as epidemiological studies, either prospective or retrospective, of exposed occupational cohorts. Often, past exposures are uncertain because of fragmentary data and constantly changing work environments. Clinical data such as chest X‐rays may never have been taken systematically and maintained. Predicting a safe exposure for a working lifetime involves the conundrum of protecting workers but not establishing standards which unfairly burden the industry, although the necessary tendency is clearly to err on the side of worker health.

381. See, e.g., Hearl, supra note 377, at 35 (citation omitted). Hearl noted that the age of the dust further complicates the issue:
Some studies show that freshly generated dust containing crystalline silica will exhibit increased toxicity in lung cells compared with aged dust, due to the recent creation and presence of surface free radicals. Therefore, specific knowledge about the process that generated the dust and the interactions of the aerosol with the environment provide important information. Id. Hearl continued by explaining,
Dust measurement and dust hazard evaluation is complex because of the need to characterize properties beyond the intensity of exposure, i.e. the dust concentration. It may be necessary to describe the exposure in terms of the particle size distribution, and the often inhomogeneous chemical or morphological properties of the dust. For fibrous materials such as asbestos, particle shape may have a profound impact on the toxicity of the material. Several descriptors of the particles may be used to characterize the concentration including: the mass of the particles, the mass of one chemical species in the particles, the active surface area, the number of particles, or the crystalline properties of the particles. Id.
382. See Graham, supra note 5, at 19293. Graham discussed that success in eliminating high silica exposure has made it more difficult to find other damaging exposure to silica:
As dust levels have fallen as a result of environmental controls and governmental standards, the health effects have become more subtle: radiographic changes may be so slight that interpreting a film as "abnormal" or "normal" may be difficult and subject to disagreement, even by expert readers. Likewise, when conglomerate silicosis was often the outcome of extremely high dust exposures, pulmonary function changes were certain and inevitable. Now, however, whether quartz exposure has any effect in the absence of radiographie changes is very much in doubt. Id.

418. A classic example of this attitude toward Borel is provided by Professor Harold Southerland's essay, Law, Literature and History: Law is at its best, I think, when used to restrain the exertion of external power by one person over another, at its worst when used, as it so often is, to legitimize, to make possible, the exertion of such power. It is hard to think of a better example than Paul Brodeur's account of the long struggle of dying plaintiffs against the asbestos industry, in particular Ward Stephenson's Herculean labors on behalf of Clarence Borel, which culminated in the Fifth Circuit's ground‐breaking decision in Borel v. Fibreboard Paper Prods. Corp., the case which would effectively break the back of the asbestos industry. Harold P. Southerland, Law, Literature, and History, 28 VT. L. REV. 1, 82 n.255 (2003) (citation omitted). Southerland goes on to quote Paul Brodeur's account to support his point:
a society that cannot summon up the sense to protect the lungs and the lives of its workers cannot hope to protect the lungs and lives of its other citizens, including its children …. The health hazard posed by … [asbestos] has called into question the conduct of a huge cross‐section of the institutions that make up the private‐enterprise system, including many of its manufacturing corporations, insurance companies, investment houses, law firms, trade unions, and governmental regulatory agencies, as well as many members of the medical and legal professions, the scientific community, and Congress. Id. at 82 (quoting PAUL BRODEUR, OUTRAGEOUS MISCONDUCT 34849 (1985)). Southerland's comment, simply an illustration for an unrelated point in his essay, is representative of the academic legal literature's view of asbestos litigation. It is difficult to square this account with the economic devastation and fraud given in more modern accounts of asbestos litigation. See, e.g., CARROLL, supra note 383. Brickman offers an interestgroupbased explanation for the academy's uncritical attitude toward asbestos litigation. Brickman, supra note 383, at 16670.

See CARROLL, supra note 383, at vii. Other scholars have commentated on the motivation of the bar and the disproportionate amount of revenue attorneys generated through the settlement process. As one scholar wrote, The obstacle that plaintiff lawyers faced in the mid 1980s is that while they had crafted the proverbial sorcerer's stone that could turn base metal into gold, they could not yet conjure up enough claimants to take full advantage of the unique opportunities that beckoned. The need for masses of claimants that would enable attorneys to fully exploit the multi‐billion dollar asset pools was met by the initiation of attorney‐sponsored asbestos screenings in the mid‐1980s.

LcDuc and Ruane report that [o]ver the years, Angeles has used his amassed power to change laws that have benefited his law practice and helped ensure that his cases come out on top. At his request, more judges have been named to hear asbestos cases in Baltimore, and significant alterations in state law have made it easier to sue asbestos makers and tobacco companies. Id. Asbestos defendants (at least the solvent ones) also organized. See PUBLIC CITIZEN, FEDERAL ASBESTOS LEGISLATION: THE WINNERS ARE … (2005), available at http:// www.citizen.org/documents/master%20report.pdf (describing lobbying campaigns by defendants).

See Coffee, supra note 415, at 1360 ("Plaintiffs' firms specializing in the field also have a special incentive to search for claimants in order to realize continuing returns from their investment in human capital. The asbestos litigation illustrates this tendency."); Christopher F. Edley, Jr. & Paul C. Weiler, Asbestos: A MultiBillion Dollar Crisis, 30 HARV. J. ON LEGIS. 383, 384 (1993). Edley and Weiler argued that [l]awyers then cast the litigation net further to find corporate pockets deep enough to satisfy the vast numbers of pending and future tort claims. Judicial legerdemain helped fill that gap with doctrinal innovations that imposed liability on firms (or their insurers) whose "misdeed," for example, was buying asbestos‐related companies in the 1960s and early 1970s‐after the human tragedy but before the litigation disaster. Id.; see also CARROLL, supra note 383, at 4748 (discussing how there have recently been claims from "people who were exposed to asbestos while working at job sites where asbestos was present in the atmosphere but not to the degree typical of the traditional industries").

Birnbaum & Jerold Oshinsky eds., 1983) ("Plaintiffs bringing civil actions for occupational injury will consider suing a number of entities which may be alleged to have contributed to the harm."). Among those the plaintiff may choose to sue include "the employer, the owner and/or lessor of the premises, the general contractor, the manufacturer of a machine or other product involved in the injury, and other parties in the product's distributional chain." Id.
452. See CARROLL, supra note 383, at 45 ("Claims for nonmalignant injuries grew sharply through the last half of the decade. Almost all the growth in the asbestos caseload can be attributed to the growth in the number of these claims, which include claims from people with little or no current functional impairment."); see Brickman, supra note 383, at 5962 (describing the rise of unimpaired claimant claims and concluding that "[t]he weight of the evidence… [demonstrates] that asbestosis as diagnosed by attorneysponsored asbestos screenings exists primarily if not exclusively as a function of the compensation system"). 453. See Coffee, supra note 415, at 1359 ("[D]uring the 1980s … asbestos plaintiffs' attorneys arranged with labor unions for portable xray trucks to screen union workers for telltale lung scars suggesting asbestos."); see also Brickman, supra note 383, at 59 ("Plaintiff lawyers are able to maintain a near inexhaustible supply of such claimants by use of attorneysponsored mass screenings to identify thousands who are then diagnosed by the processes used in the screenings, to have asbestosrelated lung conditions."); id. at 62103 (describing screenings in detail); Biederman, supra note 445, at *49 (describing mass screenings and lax controls on identification of harm). 454. See CARROLL, supra note 383, at 49 ("Because most of the traditional defendants are in bankruptcy and are not making payments any more, the litigation has moved on to a wide variety of new defendants. The number of defendants typically named in claims is growing as well."); see also id. at 31 (discussing how, in the 1990s, plaintiffs' firms sought new defendants and more money from types of defendants which they had previously treated as peripheral); Biederman, supra note 445, at *3 ("Thanks to the bankrupting of the biggest asbestos companies, the targets of [the asbestos bar's] lawsuits are a host of smaller manufacturersamong them brake manufacturers, turbine manufacturers, paint manufacturers, even the makers of the first generation of respiratory equipment intended to protect workers from asbestos."). 455. A classic example is the investment by the asbestos plaintiffs' bar in locating 1930s JohnsManville General Counsel Vandiver Brown, who had retired to Scotland. Manville resisted the "introduction of damaging correspondence between Brown and Sumner Simpson, President of Raybestos Manhattan, as trial evidence by arguing that Brown was dead and therefore his signature could not be authenticated. However, this tactic proved futile after plaintiff's lawyers found Brown alive and well in Scotland." See Barbara Pfeffer Billauer, How To Survive Workplace Litigation, in HANDBOOK OF OCCUPATIONAL SAFETY AND HEALTH 687,691 n.† (Lawrence Slote ed., 1987). 456. See Coffee, supra note 415, at 1360 (discussing how the advice for potential defendants echoes this point and noting that liability theories "continue to grow in the hands of creative plaintiffs' lawyers"); see also Billauer, supra note 455, at 687. 457. See BARON, supra note 415, at 37 ("Forum shopping, however, takes on added significance in an occupational disease case because of the substantial variation in the law, from state to state…."). 458. For example, Mississippi allowed the joinder of outofstate plaintiffs to cases filed by instate plaintiffs, allowing firms to bring claims in the Mississippi courts for nonMississippi residents. CARROLL, supra note 383, at 34. Similarly, Texas passed a statute that gave asbestos cases special access to the Texas courts during the 1990s, a statute drafted in part by one of the leading asbestos lawyers. Biederman, supra note 445, at 7. A 1998 news report on the statute identified the problem:

This small exception quickly became a gaping hole. Between 1990 and 1992, after the Texas Supreme Court made it more difficult to get rid of nonresidents' suits, the number of nonresidents filing asbestos lawsuits in Texas grew rapidly, according to numbers compiled by the Texas Civil Justice League. There were 580 claims filed by nonresidents in 1990, and 3,121 in 1992. After the 1993 bill, the numbers multiplied even more rapidly. Between 1993 and the end of 1995, more than 35,000 nonresidents filed asbestos‐related claims in Texas, as lawyers in states with shorter limitations' statutes than Texas referred their cases here. Though the loophole was closed last year, there are nearly 42,000 asbestos claims filed in Texas by out‐of‐state plaintiffs awaiting resolution. Id. (discussing the loophole and asbestos lawsuit filings in detail); see also Dow Chem. Co. v. Castro Alfaro, 786 S.W.2d 674 (Tex. 1990); Act of February 23, 1993, S.B. 2, § 1, 73d Legis. 1st R.S. (codified at Tex. Civ. Prac. & Rem. Code Ann. § 71.051 (1993)). California had a special statute of limitations for asbestos claims that tolled the running of the limitations period until the plaintiffs ability to work at his or her ordinary occupation is impaired. See CAL. Civ. PROC. CODE. § 340.2(a) (2006) (creating a limitations period that does not begin until impairment occurs); CARROLL, supra note 383, at 24 (recognizing California's "relaxed" limitations program).

See Coffee, supra note 415, at 1346 (discussing how individual plaintiffs have little control over attorneys in mass tort cases, particularly when claims concern potential future medical problems rather than immediate concerns). 465. Id. at 1365. See generally Biederman, supra note 445 (holding out Baron & Budd as the epitomy of the repeat player). Biederman quotes a defense attorney, who claims, "'My client is a very small player,' explains one defense lawyer, who asked that his name not be used because, as he puts it, 'when you irritate [Baron & Budd], they have a tendency to retaliate.'" Id. 466. The RAND study of asbestos litigation found that the pooling of claims helped induce defendants to settle even weak claims: By the mid‐1980s, however, plaintiff law firms in areas of heavy asbestos exposure (such as jurisdictions with shipyards or petrochemical facilities) had learned that they could succeed against asbestos defendants by filing large numbers of claims,

grouping them together and negotiating with defendants on behalf of the entire group. Often defendants would agree to settle all of the claims that were so grouped, including those claims that were questionable, to reduce their overall costs of litigation. By agreeing to pay questionable smaller‐value claims in exchange for also settling stronger and larger‐value claims, defendants could also contain their financial risk. Some plaintiffs might receive lower values for claims that were settled as part of a group. But litigating claims en masse lowered the cost and risk per claim for plaintiff law firms. CARROLL, supra note 383, at 23; see also Coffee, supra note 415, at 137376 (discussing "new" collusion between parties' attorneys in mass tort litigation made possible by repeat player aspects).
467. See Hechler, supra note 428, at 18 (finding that the silica plaintiffs' bar was using the "[s]ame methodology, same screening companies, same Breaders," according to a defense attorney). One problem was that many silica plaintiffs were discovered to have been previously diagnosed with asbestosis by the same screening companies and doctors. Id. Approximately half of the 10,000 plaintiffs in the Texas MDL proceeding, for example, had prior asbestos claims. Id. 468. In response to discovering possible fraud, the defense firms in the Houston MDL proceeding filed a motion seeking $1.1 million in sanctions from the plaintiffs' lawyers, and some speculate that some defendants who previously paid claims based on diagnoses that are now suspect will seek to reopen the issue. See id. 469. Judge Janis Graham Jack has received training as a nurse. Id. 470. See In re Silica Prod. Liab. Litig., 398 F. Supp. 2d 563, 60709 (S.D. Tex. 2005). The court noted that the rate of reversal of diagnosis of one of the plaintiff's screening doctors "can only be explained as a product of bias — that is, of Dr. Harron finding evidence of the disease he was currently being paid to find." Id. at 638. The two diseases produce different patterns on radiographs. As the court noted, citing testimony from Senate hearings, "[b]ecause asbestosis and silicosis have such different appearances on an xray, in a clinical setting, 'confusion between silicosis and asbestosis does not occur.'" Id. at 595. 471. See id. at 612 (noting that one diagnosing doctor spent less than four minutes per case on average). A more objective expert estimated that "the entire process of determining whether an individual has silicosis takes between 6090 minutes." Id. at 594. 472. See id. at 61516. Another physician testified that one diagnosing doctor's procedures "came nowhere near meeting what his own methodology was that he spelled out. And I have both the Third and Fourth Edition of his textbooks. And in no way does it relate to that methodology." Id. at 616, 639. The doctor's opinion was excluded because "the result driven methodology… is rife with error and speculation." Id. 473. See id. at 601 ("Because of this fee structure, Mr. Mason [owner of the screening company] testified that the emphasis was on attracting as many people as possible to the screenings and creating as many positive diagnoses as possible; as he stated, '[f]rom a business standpoint of mine, you had to do large numbers.'"); see also Press Release, House Committee on Energy and Commerce, Doctors Refuse to Testify at Silicosis Hearing; Others Recount Diagnoses 'Manufactured for Money,' available at http:// energycommerce.house.gov/108/News/03092006_l810.htm (recounting the March 8, 2006 testimony of Heath Mason, coowner of N&M, Inc., before the House Energy and Commerce Committee that "… in the case of the Campbell Cherry law firm of Houston, his company was only paid for positive diagnoses"), available at http:// energycommerce.house.gov/108/News/03092006_1810.htm; Lester Brickman, Comments on NIOSH's Proposed 'BReader Code of Ethics,' (Dec. 2005) (unpublished manuscript), available at http://ssrn.com/abstract=871965 (discussing the problems of mass screenings). 474.

These letters are dated between February 17, 2006 and March 6, 2006 and are available at http://energycommerce.house.gov/108/letters/letters.htm. 479.

The letter expressed concern about the medical procedures employed by these doctors: Medical monitoring or surveillance — including mobile facilities — can play an important part in protecting and promoting public health. The practices described in the opinion of Judge Jack, however, raise concerns that the public health purposes of these screenings are lost in a push only to identify prospective plaintiffs for a law firm. We are particularly concerned with the apparent lack of medical supervision and follow‐through associated with the mass diagnostic screenings described in In Re: Silica. As such, we must fully understand the facts and legal frameworks involved in such practices. Id.

The authors note that Underwriters Laboratory, for example, faces competition from 12 other certification organizations and thus has strong incentives to maintain the quality and reliability of its testing methods and standards. 488. Probably the most wellknown private standards are set by the International Organization for Standardization (ISO), which describes itself as "a global network that identifies what International Standards are required by business, government and society, develops them in partnership with the sectors that will put them to use, adopts them by transparent procedures based on national input and delivers them to be implemented worldwide." See ISO, ISO IN BRIEF: INTERNATIONAL STANDARDS FOR A SUSTAINABLE WORLD (2005), available at http://www.iso.org/iso/en/prods services/otherpubs/pdf/ isoinbricf_2005en.pdf. ISO 9000 sets standards for product quality, and ISO 14000 sets standards for protecting environmental quality. Together, these two generic standards are implemented by 760,900 organizations in 154 countries.
