The Workplace Hazardous Materials Information System (WHMIS) is a crucial framework for ensuring workplace safety in Canada. It focuses on three key components: labels that provide clear warnings on hazardous products, Material Safety Data Sheets (MSDSs) that offer detailed safety information, and training programs that educate workers on handling these materials safely.

Implemented through federal, provincial, and territorial laws, WHMIS establishes guidelines for identifying and managing hazardous materials. Employers must ensure that all controlled products are properly labeled, that MSDSs are accessible, and that staff receive adequate training. This system helps protect workers’ right to know about workplace hazards while also maintaining the confidentiality of sensitive business information.
