WHMIS stands for the Workplace Hazardous Materials Information System, and it is a Canadian system for providing information on the safe use of hazardous products in the workplace. It is a comprehensive program that includes labels and material safety data sheets (MSDSs) for hazardous products, as well as education and training for workers on how to handle and use these products safely.

The WHMIS training is mandatory for workers who handle, store, use or dispose of hazardous products in the workplace. Employers are responsible for providing WHMIS training to their employees, and the workers must complete the training before they begin working with hazardous products. The training is designed to ensure that workers are aware of the potential hazards of the products they are working with, and that they have the necessary knowledge and skills to handle these products safely.
