WHMIS training teaches workers how to handle hazardous products safely using the labels and safety data sheets used across Canada. Every worker who handles hazardous products must have it before starting that work.
Official website ↗WHMIS stands for Workplace Hazardous Materials Information System. It is Canada's system for sharing information about hazardous products in the workplace. The training covers how to read supplier labels, how to use safety data sheets, and how to store, handle and dispose of hazardous products safely.
Workers in construction, electrical work, maintenance and safety roles often come into contact with paints, solvents, adhesives, fuels, cleaners and other products that can cause harm. WHMIS gives you the knowledge to spot the hazards, protect yourself and your co-workers, and know what to do in an emergency.
WHMIS is not a licence that you earn once from a single national office. Training is given by your employer or by a trainer, and it is backed by federal rules from Health Canada and by the occupational health and safety regulators in each province and territory. Employers must make sure workers are trained, and they must also give site-specific instruction on the products used at their own workplace.
Most WHMIS courses finish with a short written or online quiz. It checks that you can read labels, understand safety data sheets and recognize common hazards. You can usually retake it if you do not pass the first time.
WHMIS training does not expire under one single national rule, but it should be kept current. Employers must make sure workers have up-to-date knowledge, and many require refresher training on a regular schedule. You will also need new instruction when products, labels or workplace procedures change. Keep your certificate or card, and ask your employer when your next refresher is due.
