What materials does WHMIS cover in the workplace?

WHMIS, which stands for the Workplace Hazardous Materials Information System, is a comprehensive communication system designed to ensure that workers understand the hazards associated with the materials they may encounter in the workplace. The system encompasses all hazardous materials, specifically those that may pose a risk to human health and safety when handled improperly.

This includes a broad range of chemical materials, which can range from industrial chemicals and cleaning agents to flammable materials and toxic substances. The aim of WHMIS is to provide information through labeling, safety data sheets (SDS), and worker education, enabling employees to use these substances safely and effectively.

In contrast, the other choices are limited in their scope. For example, only focusing on pesticides or hazardous substances excludes many other chemical materials that are also regulated under WHMIS. By covering all chemical materials, WHMIS ensures a more comprehensive approach to workplace safety, promoting awareness and understanding of a wider array of potential hazards.
