In Ontario, the Workplace Hazardous Materials Information System (WHMIS) is a crucial component of workplace safety. WHMIS training is mandatory for all workers who handle hazardous materials, and employers are required by law to ensure that their workers are adequately trained to understand the hazards and safety precautions associated with the hazardous materials they work with.

What is WHMIS in Ontario?

WHMIS has three key components: labels, safety data sheets (SDSs), and worker education and training. Labels on hazardous materials containers provide information about the hazards associated with the material, as well as instructions for safe handling, storage, and disposal. SDSs provide more detailed information about the hazards and safety precautions associated with the material, including information on first aid, fire fighting, and spill response. Worker education and training is designed to ensure that workers understand the hazards associated with the materials they work with, and are able to take the necessary safety precautions to protect themselves and their colleagues.

WHMIS is a comprehensive system designed to ensure that workers are informed about the hazardous materials they work with, and the safety precautions they need to take to avoid injury or illness. The system is based on the United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS), which provides a standardized approach to identifying and communicating the hazards associated with chemicals.

Who in Ontario Needs WHMIS Training?

All workers who handle hazardous materials are required to receive WHMIS training, including full-time, part-time, and temporary workers, as well as contractors and self-employed individuals. This includes workers in a wide range of industries, including manufacturing, construction, healthcare, and retail.

Employers are responsible for ensuring that their workers receive the necessary training, and for keeping records of their workers’ training. Workers are also required to participate in refresher training on a regular basis, to ensure that their knowledge is up-to-date and that they understand any new hazards or safety precautions associated with the materials they work with.

How is WHMIS Training Delivered?

WHMIS training can be delivered in a variety of formats, including classroom instruction, online courses, and self-directed study. The training must cover the following topics:

• The hazards associated with the materials workers will be working with
• How to read and understand labels and SDSs
• Safe handling, storage, and disposal of hazardous materials
• Emergency procedures, including spill response and first aid

Employers in Ontario may choose to develop their own training programs, or they may use pre-existing training materials developed by third-party organizations. In either case, the training must meet the requirements set out by the Ontario Ministry of Labour, Training and Skills Development.
