WHMIS 2015 Labels

Canada has aligned the Workplace Hazardous Materials Information System (WHMIS) with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), resulting in new standardized classification criteria; label requirements; and safety data sheet (SDS) requirements.

The product label is the worker's first source of information about the hazards of a product and how to use it safely. In WHMIS 2015, supplier labels for hazardous workplace products must display the product identifier and supplier identifier, as well as hazard pictogram(s); signal words (new); hazard statement(s); and precautionary statement(s) assigned based on the hazard classification.

Workplace labels must display the product identifier, safe handling precautions, and reference to the SDS, if available.


❶  Product Identifier
The name of the product is printed exactly as it is appears on the Safety Data Sheet SDS and the container.
❷  Hazard Pictograms
WHMIS 2015 Hazard pictograms are prominently displayed. These pictograms are determined by the hazard classification of the product. No pictogram is required in specific cases.
❸  Signal Words
Use of only one signal word. Either, "Danger" or "Warning" emphasize the hazard and the severity of it.
❹  Hazard Statements
A succinct standardized phrase based on the hazard classification of the product that describes the hazard the product poses to the users.
❺  Precautionary Statements
A standardized description of measures recommended to minimize or prevent adverse effects resulting from exposure to the product. Information includes protective equipment and emergency measures.
❻  Supplier Identifier
Information for the company that manufactured, packed, imported and/or sold the product. The company is also responsible for the WHMIS label.


❼  Safe Handling Precautions
Information for safe use of the product which may include pictograms or other supplier label information and reference to SDS if available.
