The current OSHA permissible exposure limit (PEL) for nuisance dust is 15 mg/m3 as an 8-hour time-weighted average (TWA) exposure. The ACGIH has published a threshold limit value (TLV) for inhalable dust of 10 mg/m3. OSHA is required to consider economic and feasibility influences as well as health impacts for establishing or updating PELs. The ACGIH can consider only the health impacts when establishing TLVs. Imagine you are a safety officer having to establish an occupational exposure limit (OEL). Discuss how you would come to this exposure limit. Part 1 needs to be on a separate sheet from Part 2. Part 2 has to be 2 pages not counting Part 1. Your journal entry must be at least 200 words. No references or citations are necessary.
