- Why: Ensure exposure limits are aligned with best practices and available science
- Key topics: Threshold limit values, chemicals, industrial hygiene
Summary
Exposure limits are upper limits on the acceptable concentration of a chemical substance or class of substances in workplace air. WorkSafeBC has a committee dedicated to ensuring exposure limits in B.C.’s workplaces adhere to best practices and are updated in alignment with advances in the underlying science.
A key source of this information is the American Conference of Governmental Industrial Hygienists (ACGIH). WorkSafeBC’s committee has reviewed recent changes published by ACGIH and has proposed changes to the exposure limits for 22 substances found in B.C. workplaces.
Results
With the exception of benzene, the proposed exposure limits were sent to the Board of Directors for decision and have been adopted.
The benzene EL continues to be under study, and a call for consultation will be posted prior to Board submission.
