Workplace Hazardous Materials

Workplace Hazardous Materials Information System (WHMIS)

All sites must complete an annual hazardous substances safety review. This review includes confirming that hazardous products are properly labelled, Safety Data Sheets (SDS) are readily accessible, and that staff who use hazardous substances are trained and certified in accordance with WHMIS (2015) requirements.
