Workplace Hazardous Materials
Information System (WHMIS) Policy
Appendix B – WHMIS Training Standard
The Workplace Hazardous Materials Information System (O. Reg 860), requires employers to ensure
that workers who work with or in proximity to a controlled product are informed about all hazard
information received from the supplier and all other hazard information of which the employer is or
ought to be aware concerning the use, storage and handling of the controlled product.
The regulation also requires employers to ensure that every worker who works with or in proximity to
a controlled product is instructed in:




The contents required on a supplier label and workplace label, and the purpose and
significance of the information contained on the labels;
The contents required on a material safety data sheet and the purpose and significance of
the information contained on a material safety data sheet;
Procedures for the safe use, storage, handling and disposal of a controlled product;
Procedures for the safe use, storage, handling and disposal of a controlled product when it
is contained or transferred in,
 A pipe,
 A piping system including valves,
 A process vessel,
 A reaction vessel, or
 A tank car, a tank truck, an ore car, a conveyor belt or similar conveyance;
 Procedures to be followed when fugitive emissions are present, and
 Procedures to be followed in case of an emergency involving a controlled product.

Evaluation
An evaluation must be conducted to ensure the employee understands the material covered in the
course. Assistance will be provided to address gaps identified through this evaluation until the
employee understands course content and successfully completes the evaluation.
Note: A generic power point presentation including participant workbook, sample MSDS, glossary of
terms, copy of the WHMIS regulation and a test is available to Human Resources Health &
Safety staff on HR Backstage. The material is available to others by contacting Evelyn Lao,
Program Assistant, Occupational Health, Safety and Workers’ Compensation Unit at
elao@toronto.ca or 392-3919.
Product-Specific Training Standards
Employees shall be given product-specific training for all1 products they may work with or be exposed
to. Product-specific training shall cover the following minimum topics:


1
What hazardous products are used at the workplace
The location of material safety data sheets (they must be readily accessible to employees at all
times)
It may not be necessary to provide training on every product in the workplace. Training may be conducted on groups or
families of chemicals with similar properties/hazards.
