The Workplace Hazardous Materials Information System commonly referred to as WHMIS is a four-part plan for providing information on the safe use of hazardous materials used in Canadian workplaces. WHMIS consists of hazard identification and product classification, labeling, material safety data sheets, and worker training and education. WHMIS was legislated in Canada in 1988 and the majority of the "information" requirements (and exemptions) of WHMIS legislation were incorporated into the Hazardous Products Act and the Hazardous Materials Information Review Acts. The occupational health and safety components of WHMIS that apply to federal employees and others covered by the Canada Labour Code (CLC) are specified in the CLC and the Canadian Occupational Health and Safety Regulations (Part X).
