Basics of WHMIS

WHMIS is made up of three main parts. The two most important physical parts of WHMIS are labels and safety data sheets (SDSs).

Hazardous Material Container Labels supply basic information about the product, along with pictograms that highlight the potential dangers. All containers of hazardous materials must be properly labelled. There are specific requirements for both supplier labels and workplace labels.

Safety Data Sheets contain comprehensive information about hazardous materials, including their content/ingredients, directions for proper use, correct cleanup and first-aid procedures. A Safety Data Sheet (SDS) must be available to employees (“workers”) for every hazardous product that is used.

Education/training to ensure anyone working with hazardous materials knows the potential dangers and the correct handling methods for these products. Under WHMIS regulation, you have a right to know about the hazardous materials in your workplace. Your employer is responsible to train you and those who work in proximity to hazardous materials.
