WHMIS: Workplace Hazardous Materials Information System

In order to ensure the health and safety of companies, the Workplace Hazardous Materials Information System (WHMIS) aims to facilitate access to information on hazardous materials used in the workplace. WHMIS is administered by the Canadian Center for Occupational Health and Safety (CCOHS) and is governed by law. WHMIS includes the classification of hazardous products, labeling requirements, safety data sheets and worker training.

A shared responsibility:

  • Through federal laws, WHMIS targets suppliers of hazardous products under the Hazardous Products Act (HPA) and the Hazardous Products Regulations (HPR).
  • Provincial laws particularly concern workplaces, employers and workers are therefore concerned.
  • In Quebec, the CNESST is responsible for ensuring compliance and application of WHMIS standards according to the Regulation respecting information concerning hazardous products and the Act respecting occupational health and safety (LSST).

Consequence: the worker was fatally struck on the head when the barrel exploded.

Causes: 1) Staff training is insufficient on hazardous products. 2) There are gaps in the planning of tank maintenance work. “
