RESPONSIBILITIES UNDER WHMIS
The purpose of WHMIS Regulations is to protect all workers who could potentially be exposed to hazardous products during work.
The supplier, the employer and the worker share responsibility in achieving the key outcome of a safe workplace, free from safety or health hazards. This section will also discuss exemptions not regulated by WHMIS. The responsibility of achieving the key outcome of a safe workplace is shared by the supplier, the employer and the worker and begin at the Supplier.
EXEMPTIONS
- Although WHMIS applies to all workplaces where hazardous products are used, there are many products which are not regulated under the Hazardous Products Act and Regulations. In most cases, these products must conform to other, more strict regulations.
- For example, radioactive material is not regulated by WHMIS, but it must conform to the requirements of the Atomic Energies Act.
- Products exempt from WHMIS are not exempt from the requirement of training or labelling. Maintaining the workers’ Right to Know remains constant.

Exempt Product List
The following products are exempt from WHMIS:
The Globally Harmonized System of Classification and Labelling of Chemicals (GHS)
In February 2015, Canada amended the Hazardous Products Act and published the Hazardous Products Regulations to align WHMIS with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The goal of GHS is to have:
- a common set of rules for classifying hazardous products, common rules for labels, and
- a standard format for Safety Data Sheets (SDSs) that is adopted around the world.
The combined system is identified as WHMIS 2015.
The GHS Divisions of Hazardous Materials
The GHS system segregates hazardous materials into the following divisions:
- Physical Hazards
- Health Hazards
- Environmental Hazards
