Under the WHMIS system, which of the following is not a responsibility of suppliers?

Under the Workplace Hazardous Materials Information System (WHMIS), suppliers have specific responsibilities to ensure that hazardous products are properly classified, labelled, and accompanied by appropriate Material Safety Data Sheets (MSDS). These responsibilities are essential for ensuring that users of the products are informed about the hazards and can take necessary precautions.

The classification of the product is a key duty of suppliers as it involves determining the hazards that are presented by the chemical or material. After classification, suppliers must provide comprehensive Material Safety Data Sheets, which serve as critical resources that detail the properties of the substances, safety measures, and emergency procedures. Furthermore, suppliers must ensure that products are labelled correctly in accordance with WHMIS standards, so that users can easily identify hazards and adhere to safety requirements.

While training workers is an important aspect of workplace safety, it is primarily the responsibility of employers. Employers must ensure that their workers receive adequate training and are informed on how to read labels and understand the information provided in Material Safety Data Sheets. Thus, the responsibility for training is not on suppliers, which makes it the correct distinction in this context.
