Discussion Post: OSHA Journals
• 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.
• Discuss a gas or vapor that you have dealt with in a workplace. Include information about how worker exposures were evaluated. If you have never had sampling for a gas or vapor performed in your workplace, review either the NIOSH Manual of Analytical Methods (NMAM) or the OSHA Sampling and Analytical Methods, and choose a vapor or gas that looks interesting to you.
The response should include a reference list. Using one-inch margins, Times New Roman 12 pnt font, double-space and APA style of writing and citations.
