The Workplace Hazardous Materials Information System, or WHMIS, is a comprehensive system for providing health and safety information on the safe use of hazardous products in Canadian workplaces. In 2015, the Government of Canada amended the Hazardous Products Act and the Hazardous Products Regulations to align WHMIS with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). WHMIS 2015 sets forth the roles and responsibilities of suppliers, employers and employees. It also includes new harmonized criteria for hazard classification, and updated requirements for hazard labels and safety data sheets. In this course, you will learn about WHMIS, including the roles and responsibilities of suppliers, employers and employees; physical and health hazards encountered in the workplace; required elements and standards of WHMIS-compliant labels and safety data sheets; and controls for eliminating or minimizing exposure to hazardous materials in the workplace. This course was developed with subject matter support provided by Pinchin Ltd., an environmental, health and safety consulting firm with offices across Canada. Please note, the course materials and content were current with the laws and regulations at the time of the last expert review, however, they may not reflect the most current legal developments. Nothing herein, or in the course materials, shall be construed as professional advice as to any particular situation with respect to compliance with legal statutes or requirements.
