Permissible Exposure Limits (PELs)

OSHA sets enforceable permissible exposure limits (PELs) to protect workers against the health effects of exposure to hazardous substances. PELs are regulatory limits on the amount or concentration of a substance in the air. They may also contain a skin designation.

OSHA PELs are based on an 8-hour time weighted average (TWA) exposure.
