All About WHMIS Labels

The label is the worker’s first source of information about the product’s hazards. Before using a hazardous product, workers should review its label to ensure they are handling the product safely.

There are two different types of labels: supplier labels and workplace labels.

Supplier Labels


A sample supplier label.

Suppliers are responsible for labelling the hazardous products that they provide to customers. Supplier labels must be written in English and French. The classification of the product will require that some of the following information be displayed on a label.

  1. Product Identifier
    The brand name, chemical name, common name, generic name or trade name of the hazardous product.
  2. Supplier identifier
    The name, address and telephone number of either the Canadian manufacturer or the Canadian importer.
  3. Pictograms
    Some products require the display of a symbol to indicate a hazard classification.
  4. Signal Word
    Some hazard classes require the use of either “Danger” or “Warning” as a signal word to alert the reader to potential hazard of a material and to indicate the severity of the hazard.
  5. Hazard Statements
    Brief standardized phrases that describe the nature of the hazard posed by a hazardous product.
  6. Precautionary Statements
    Standardized phrases that describe measures to be taken to minimize or prevent adverse effects resulting from exposure to a hazardous product or resulting from improper handling or storage of a hazardous product. This should include information about protective equipment, emergency measures and first aid treatment.

Workplace Labels

Employers are responsible labelling hazardous products in the workplace if:

  • a hazardous product is produced (made) at the workplace and used in that workplace,
  • a hazardous product is decanted (e.g., transferred or poured) into another container, or
  • a supplier label becomes lost or illegible (unreadable).

It is recommended that workplace labels include all of the following information:

  1. Product Identifier
    The product name exactly as it appears on the original container from the supplier and on the Safety Data Sheet.
  2. Pictograms
    Some products require the display of a symbol to indicate a hazard classification. The pictograms displayed on a workplace label should be the same that were displayed on the supplier label.
  3. Precautionary Statements
    Standardized phrases that describe measures to be taken to minimize or prevent adverse effects resulting from exposure to a hazardous product or resulting from improper handling or storage of a hazardous product. This should include information about protective equipment, emergency measures and first aid treatment.
  4. Safety Data Sheet Reference
    Make note that a Safety Data Sheet is available with more information.
