The WorkSafeBC Board of Directors approved the adoption of the 2012 new and revised American Conference of Governmental Industrial Hygienists Threshold Limit Values (ACGIH TLVs) as BC Occupational Exposure Limits (OELs) for carbonyl sulfide, diacetyl, ethyl formate, and nonane. It also adopted the revised ACGIH TLVs for beryllium and compounds, vanadium pentoxide, alpha-methyl styrene and Portland cement. Effective Feb. 1, 2015, these substances will be removed from the Table of OELs for Excluded Substances in Policy R5.48-1 and the ACGIH TLVs will be assigned as BC OELs.
