PREVENTION THROUGH DESIGN: SECTIONS 5.1.1 TO 5.1.4 OF 210 - This chapter, and ANSIIAIHA Z590.3-201 l, the Ameri~an National Standard titled Prevention through Design: Guidelines for Addressing Occupational Hazards and Risks in Design and Redesign Proce~ses, r~late to several provisions in ZlO: risk assessment, Section 5.1.1; hierarchy of controls, Section 5.1.2; design requirements, Section s: 1.3; and procurement, Section 5.1.4. lt 1 also pertains to the prevention of serious injuries and fatalities. ' , ' We said earlier that applying. prevention through design principles early 'in the design and redesign processes reduces the p<>lential for incidents resulting in serious harm or damage. In Chapter 3 "Inflovations in Serious Inj?ry and Fatality Prevention",

which gives prominence and Significance to preverition through Oesign. The following pnnctples are offered in support of the premise that prevention ·through design should have such importance. ·,
I. Hazards and nsks are most effectively and economically avoided, eliminated, or controlled in the clesign and redesign ·pro_cesses. .
2 · Hazard analysis i the most iinportant safety process in that, if it fails, all other
processes are likely to be ineffective (Johnson, p. 245). 3. Risk 885\'ssment should be the comerst~n~ of an operational risk management

HISTORY
In the early 1990s, several safety professionals recognized through _their studies of investigation reports for occupational injuries and illne.sses that design cau~al factors were not addressed adequately. For example, a study made by this author at that time indicated that although there were implications of workplace and work method design inadequacies in over 35% percent of the· investigation reports analyzed, the corrective actions proposed did not relate to the design implications. That study is supported by a later analysis made in Australia. · · ·
In Guidance On The Principles Of Safe Design For Work, issued in 2006, com- ments are made on the "contribution that the design of machinery and equipnienrhas on the incidence of fatalities and injuries 1.n Australia."
Of the· 210 identified workplace fatalities~ 77 (37%) definitely or probably ·had design-related issues involved. Design c'ontributes to a(least -30% of work- related serious nonfatal injuries·. (p. 6) • ·· i · · ·
To provide the necessary education for designers, safety professionals are encour- :~ to develop their own supportive data on incidents in which-design shortcomings
2 ; 1 identified. That initiative should be followed by a major effort to have Z590.3- I 1 be accepted as a design guide. · ·
eq t was also noted in the early l 990s that designing for safety was addressed inad- uately · a£ . . terns t . in s et_y-r~lated literature, and that the safety and health management s~s-

Note: Incidents that have the potential to result in occupational injuries and •u. nesses can also result in damag~ to prol":rty and .business i?te~ption, and darn~e to the environment. Reference 1s made m several places m this standard to those additional loss potentials which may require evaluation and resultant action . .

a Pre-operatiQnal stage:.in the initial planning, design, specification, prototYPing, and construction processes, where the opportunities are greatest and the costs are lowest for hazard and risk .avoidance, elimination, reduction; or control.
b. Operational stage: where •hazards and risks are identified and evaluated and mitigation actions are taken throµgh redesign initiatives or changes in work methods before incidents or exposures occur.
c. Post-incident stage: where investigations are made of incidents and exposures to determine the causal factors that will lead to appropriate interventions and acceptable risk levels.
d. Post-operational stage: where demolition, decommissioning, or reusing/retiuilding operations are undertaken:
The application goals of utilizing prevention , through design concepts in an occupational setting are to:
a. Achieve acceptable risk levels.
b. Prevent or reduce occupationally related injuries, illnesses, and fatalities. c. Reduce the cost of retrofitting necessary to mitigate hazards and risks

1. Leadership is a key and critical factor in successfully implementing and deploying the risk assessment process.
2. Integrating risk assessment in an organization is a process that generally follows a sequence of phases. (Three frameworks are discussed.)
3. Engineering design needs to change to include the risk assessment process to more effectively move safety into design. Only by changing the design process will risk assessment efforts succeed.
4. Introducing the risk assessment process will explicitly change the design pro- cess, allowing hazards 'to be identified and risk reduction methods to be incor- porated early in the design process. As with any new process or substantial change, people may resist.

Toe first PtD workshop was held in July-2007. Attenclees included representa- tives from industry, labor, government, and academia. Proceedings were published in 2008 in a dedicated· issue of the Journal of Safety Research. A PtD' Council was· formed to guide the new • initiative. Council members were specialists in occupational ·safety and health and arranged strategic goals around the themes of Research, Education, Practice, and , Policy; The Plan for the National Initiative (http://www.cdc:gov/niosh/docs/20H-12l/) was publishedin 2009.
In 2010/ the PtD t ole of the •designer/engineer was investigated by -bench- marking PtD regulations of designers in the• construction industry in the United Kingdom (UK) to further understand the potential impacts and opportunities for implementation of the PtD concept in the US. · The Education and Information Division of NIOSH coordinated a workshop, titled "Making Green Jobs Safe," ~hich developed 48 compelling activities· for including worker ·safety and health ~to green jobs and sustainable design.

In August 2012, PtD -and .. the NIOSH -Nanotechnology .Research Center (NTRC) collaboratecj with the State University New-York at Albany, College of Nanos.cale Science & Engineering, to hold a Safe NanQ-Design workshop. The purpose was to discuss the value pf. applying .PtD to safely synthesize engineered nanoparticles and safely .commercialize nano-enabled products, Applying PtD concepts in organizations handling engineered nanomaterials assures that worker health and safety is considered at each step in the supply chain, resulting in sustainable health and safety performance.
By the spring of 2013, two additional textbooks were published. A total of93 first generation publications were cited by 721 second generation public~tions, Fifteen consensus standards containing PtD concepts have been publish_ed. More than two dozen universities have expressed interest in the PtD Education Modules for existing undergraduate classes. The first to be published was tbe Architectural Design and Construction Instructor's Manual (http://www.cdc. gov/niosh/docs/2013-133). PtD

successful PtD practices. In addition to our continued dialog with USGBC and CURf, NIOSH is collaborating with industry to identify Best Practices so these can be front loaded into the Capital Design Process.
When a root cause analysis uncovers a design-related hazard, the design solution should be documented for future reference during the conceptual design phase of similar facilities or equipment.
Policy activities are focused on developing a PtD culture in industry. Including PtD into consensus standards is the first step in the development of a PtD culture.
CONCLUSION
: 1 :m~nt of safety professionals in the design processes is hugely more extensive
