✍️ Sample WHMIS Questions & Answers

1. Under WHMIS, which of the following is NOT required on a supplier label?

Supplier labels must include the product identifier, hazard symbols, risk and precautionary statements, and supplier information — not individual worker names.

2. A lab technician decants a corrosive acid into a smaller beaker for a procedure that will take two hours. What labeling is required?

Unless the immediate-use exemption applies, a workplace label identifying the product and safe handling information is required on the decanted container.

✓ Gas cylinder

The gas cylinder pictogram applies to compressed, liquefied, dissolved, and refrigerated liquefied gases stored under pressure.

4. A worker receives a drum labeled with both the skull and crossbones and the corrosion pictogram. This combination means:

5. What should a comprehensive workplace emergency response plan for hazardous materials include according to WHMIS best practices?

✓ Procedures for spill containment, evacuation, first aid, and notification of authorities

A complete emergency response plan must address spill containment, worker evacuation, first aid measures, and how and when to notify regulatory authorities and emergency services.
