OCRC Report: Occupational exposure limits for carcinogens in Ontario workplaces: Opportunities to prevent and control exposure

Occupational exposure limits are legal or recommended maximum allowable concentrations of a hazardous substance in a workplace. These values are usually set by national authorities or other institutions. To help prevent cancer and protect health, it is important that limits for carcinogens are rigorous, up-to-date, and reflect the best possible standards for workers.

The OCRC has surveyed occupational exposure limits in Ontario and compared them to values across Canada and in other jurisdictions. Based on the results, specific recommendations have been put forward for carcinogens that can have more rigorous limits in Ontario. More information on this initiative can also be found on our projects page.
