The parts of the Occupational Health and Safety Act (OHSA) that deal with toxic substances have two purposes. One is to ensure that worker exposure to toxic substances is controlled. The other is to ensure that toxic substances in the workplace are clearly identified and that workers receive enough information about them to be able to handle them safely. As well, the Act gives the general public access to information about toxic substances used by regulated employers in their workplaces. http://www.labour.gov.on.ca/english/hs/pubs/ohsa/ohsag_part4.php The control of toxic substance
The Act enables the Lieutenant Governor in Council (LGIC) to prescribe a toxic substance as a “designated substance”, and to prohibit, regulate, restrict, limit or control its use, handling and removal in regulated workplaces. Regulation for Control of Exposure to Biological or Chemical Agents The Act enables the LGIC to regulate the atmospheric conditions to which a worker may be exposed in the workplace. The Regulation respecting Control of Exposure to Biological or Chemical Agents, Regulation 833, sets occupational exposure limits (OELs) for approximately 725 biological and chemical agents
