If you have hazardous materials in your workplace, you may have noticed changes to how they are labelled and the documentation that accompanies them. Have you seen new pictograms indicating hazard classes that didn’t previously exist, or have you received a Safety Data Sheet (SDS) rather than a Material Safety Data Sheet (MSDS) from a supplier or distributor? If so, you have hazardous materials in your workplace that conform to the new Workplace Hazardous Materials Information System (WHMIS) standards. If not, you will likely start to notice changes in the near future. The new labelling and documentation are part of the move to align Canada’s legislation with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The changes started with updates to federal WHMIS legislation, specifically the Hazardous Products Act and the new Hazardous Products Regulations. Provincial and territorial legislative updates are based on the model set out in the federal legislation. This is to ensure uniformity between jurisdictions.
