Why was WHMIS introduced?

WHMIS, or the Workplace Hazardous Materials Information System, was introduced in Canada to ensure the safe handling, use, and storage of hazardous materials in the workplace. It aims to provide workers with essential information about hazardous substances through labels, safety data sheets, and worker education and training programs. By standardizing hazard communication, WHMIS enhances workplace safety and helps prevent accidents and health issues related to exposure to hazardous materials.
