WHMIS, or the Workplace Hazardous Materials Information System, is a Canadian system that provides important information about hazardous materials used in the workplace. This information includes information about the dangers of these materials, such as the health effects of exposure, as well as information about safe handling, storage, and disposal.

WHMIS is required in many different types of jobs where workers may come into contact with hazardous materials. Some examples of jobs that may need WHMIS include:

1. Healthcare professionals: Doctors, nurses, and other healthcare workers may come into contact with hazardous materials such as chemicals used in medical treatments, disinfectants, and other hazardous substances.
2. Construction workers: Construction workers may come into contact with hazardous materials such as solvents, adhesives, and paints.
3. Manufacturing workers: Workers in manufacturing industries may work with hazardous chemicals, such as solvents, acids, and other toxic substances.
4. Laboratory workers: Scientists and laboratory technicians may work with hazardous materials such as chemicals, biological agents, and radioactive materials.
5. Cleaning and maintenance workers: Cleaning and maintenance workers may come into contact with hazardous materials such as cleaning agents, solvents, and pesticides.

These are just a few examples of the many different types of jobs that may require knowledge of WHMIS. If you work with hazardous materials or in an environment where hazardous materials are present, it’s important to understand the requirements of WHMIS and how to stay safe.
