If so, follow general safety requirements to evaluate airborne exposures to see if they exceed the applicable PEL. Additional requirements for specific chemicals could apply

Of the thousands of chemicals used in workplaces, only a few hundred have Permissible Exposure Limits (PELs).

PELs are regulated limits set to protect most workers from potential harm caused by exposures to airborne hazardous chemicals.

Before using PELs you'll need to evaluate exposures as detailed in WAC 296-841-20003 (3.17 MB PDF) and WAC 296-841-20005 (3.17 MB PDF).

Compare results from your exposure evaluation to the PELs in WAC 296-841-20025, Table 3 "Permissible Exposure Limits (PELs) for Airborne Contaminants" (3.17 MB PDF).

Follow all other applicable requirements in Airborne Contaminants, Chapter 296-841, WAC and other applicable rules.
