Permissible Exposure Limit OSHA implemented a permissible exposure limit (PEL) of 50 µg/M3 (micrograms per cubic meter). This is about half the current PEL for general industry and about one-fifth the current PEL for construction. This PEL is the maximum allowable exposure averaged over an eight-hour workday. OSHA is also updating the measurement method.
