Qué debes saber antes del examen

Employers must educate and train workers on the hazards and safe use of hazardous products. Workers must take part in that training.
Each province or territory sets its own WHMIS education and training rules. Federally regulated workplaces follow federal rules.
Training is site-specific. If you change employers, your new workplace must train you on its own products and procedures.
Supplier labels and safety data sheets (SDSs) must be in both English and French.
An SDS has 16 sections. Suppliers must update an SDS within 90 days, and a label within 180 days, of learning significant new data.
WHMIS uses two signal words: "Danger" for more severe hazards and "Warning" for less severe hazards.
Amendments to the Hazardous Products Regulations came into force on December 15, 2022. The transition period ended on December 14, 2025.

Preguntas frecuentes

Is there an official national WHMIS exam?

No. Provincial, territorial and federal OHS laws require WHMIS education and training, but there is no single national exam. Your employer or training provider may check your knowledge with a written quiz or a practical demonstration.

Does WHMIS training expire?

There is no national expiry date. Employers should review their WHMIS program at least once a year and give refresher training when products, hazards or work conditions change. Check your province or territory for any extra rules.

What are the WHMIS pictograms?

WHMIS uses eight GHS pictograms with a red diamond border (flame, flame over circle, gas cylinder, corrosion, exploding bomb, skull and crossbones, health hazard, exclamation mark) plus the biohazardous infectious materials pictogram, which has a black circle border.

When is a workplace label needed?

When a product is poured into another container, when a hazardous product is made and used in the workplace, or when the supplier label is lost or cannot be read.

Do I need new WHMIS training if I change jobs?

Yes, at least the site-specific part. General WHMIS education may carry over, but each workplace must train you on its own products, procedures and emergencies.
