Canada British Columbia exposure limits for chemical and biological substances

Canada British Columbia exposure limits for chemical and biological substances established by WorkSafeBC under the Occupational Health and Safety Regulation, primarily adopt the Threshold Limit Values (TLVs®) from the ACGIH, covering occupational exposure limits (OELs) for over 1,000 substances including 8-hour TWAs, 15-minute STELs, and ceiling limits (C). WorkSafeBC retains the authority to set exception limits for specific substances; employers must ensure workplace exposures do not exceed the statutory OELs of British Columbia.
