April 1: ACGIH Published New or Revised TLVs for Certain Substances


The American Conference of Governmental Industrial Hygienists (ACGIH) published the 2014 new or revised Threshold Limit Values (TLVs). WorkSafeBC added various substances to the Table of Occupational Exposure Limits (OELs) for Excluded Substances in Prevention Policy R5.48-1, including argon, helium, hydrogen, neon and nitrogen. If the Board approves the adoption of the ACGIH TLVs as BC OELs, the substances will be removed from the Table and the ACGIH TLVs will then apply.
