Which of the following best describes the purpose of WHMIS?

The purpose of the Workplace Hazardous Materials Information System (WHMIS) is fundamentally focused on ensuring that hazardous materials are properly classified and communicated. This system is designed to provide information about hazardous products that are used in the workplace, including details about their handling, storage, and potential hazards.

By classifying hazardous materials and clearly communicating their risks through labels, safety data sheets, and worker education, WHMIS aims to protect workers and ensure they have the knowledge necessary to work safely with these substances. This system plays a critical role in promoting safety in the workplace by fostering an informed environment where employees know how to manage hazardous materials effectively.

Other options might highlight various important aspects related to safety or cost, but they do not capture the main objective outlined in WHMIS. The focus on proper classification and communication distinguishes WHMIS as an essential framework within Canadian regulation for managing hazardous materials in the workplace.
