A good chemical management program will require implementation of the Workplace Hazardous Materials Information System (WHMIS). The WHMIS requirements in Ontario are identified in Regulation 860 made under the Occupational Health & Safety Act (OHSA).

A WHMIS program consists of three basic elements: supplier & workplace labels, Material/Safety Safety Data Sheets (MSDS/SDS) and employee training.

  1. Labels are required on containers of WHMIS controlled products.
    • Suppliers must attach a a Supplier Label to any WHMIS controlled product.
    • If a chemical is poured off into an unlabeled container, you must place a workplace label to the container. A workplace label has to include the name of the chemical, a reference to the MSDS and Safe Handling information specific for the chemical.
  2. Material Safety Data Sheets (MSDS) are required in a workplace for each WHMIS controlled product. The employer is responsible to ensure they are available to employees and are less than three years old.
  3. WHMIS training is required for each employee within the FHS. WHMIS 2015 training is offered through the MOSAIC system. The course code is WHMS15.

The Ministry of Labour administers the WHMIS Regulation and they offer a Guide to the WHMIS Legislation.
