Part 4 Chemical Hazards, Biological Hazards and Harmful Substances

Section 22 Worker exposure

This section describes what needs to be done in the event that a worker is exposed to a substance in excess of its OEL. Steps must be taken immediately to prevent further exposure of the affected worker to airborne concentrations in excess of the OEL. The employer must also inform the affected worker of the nature and extent of the exposure. This information should include the identity of the substance, its concentration, the duration of the exposure, the toxicological properties of the substance and its potential health effects. The source of emission causing the excessive exposure must be identified and controlled before work can resume.

If the work site has been required by Ministerial Order to have a joint work site health and safety committee, the employer must inform the committee of the incident and the steps taken to control the excess exposure. If there is a voluntary committee, then the employer should provide this information to it. If there is no committee, the employer should provide this information to workers at the work site.
