Each year, the American Conference of Governmental Industrial Hygienists (“ACGIH”) publishes a list of substances for which they have set new or revised threshold limit values (“TLVs”).

In accordance with section 5.48 of the Occupational Health and Safety Regulation, these new or revised TLVs were automatically adopted as WorkSafeBC occupational exposure limits (“OELs”) unless otherwise determined by the Board.

WorkSafeBC requested stakeholder feedback on the new or revised 2009 OELs.

Consultation closed November 30, 2009.
