How OELs are set and what to do when measurements approach the limit.

Sources of OELs

ACGIH TLVs, OSHA PELs, NIOSH RELs, and provincial regulations (e.g. Ontario Reg. 833). CASSEN reports all measurements with the relevant limit alongside, so the decision is on the page rather than in a separate document.
