Understanding WHMIS Labels

In Canada, the Workplace Hazardous Materials Information System (WHMIS) mandates that hazardous products in the workplace be properly labelled to ensure the safety of workers. Labels serve as a first line of defense by providing essential information about the hazards associated with a product, recommended precautions, and first-aid measures.

Types of Labels

There are two main types of labels: supplier labels and workplace labels. These labels are key tools in ensuring safe handling of hazardous materials.

Supplier Labels

Supplier labels provide crucial hazard-related information directly from the supplier and are required for all hazardous products. These labels must display several key elements to ensure safety in handling and response.

Important Information

Product Identifier: The name of the product (brand name, chemical name, etc.)
Hazard Pictograms: Symbols that visually represent the hazard
Signal Word: A word indicating the severity of the hazard (either “Danger” or “Warning”)
Hazard Statements: Descriptions of the specific dangers posed by the product (e.g., “May cause cancer”)
Precautionary Statements: Safety measures to minimize or avoid exposure (e.g., “Wear protective gloves”)
Supplier Identifier: The name and contact information of the supplier

The label must also include bilingual information in both English and French, as per Canadian regulations. It’s important to confirm that the hazard pictograms, signal word, and hazard statements align with the information on the Safety Data Sheet (SDS).

Signal Words

Danger: Used for more severe hazards.
Warning: Used for less severe hazards.

When Supplier Labels are Required

A supplier label must be applied to hazardous products provided by the supplier. If the hazardous product is used in its original container, no additional label is required. However, a new label is needed in these situations:

The hazardous product is decanted (transferred) into a different container.
A product is made in the workplace and does not have a pre-existing supplier label.
A supplier label becomes damaged or unreadable.

Workplace Labels

Workplace labels are a simplified version of supplier labels and are used in specific circumstances. Employers are responsible for ensuring that these labels are applied when necessary.

When are Workplace Labels Required?

For products produced onsite and used within the workplace.
When a product is transferred from one container to another.
When the supplier label is lost or damaged.

What Information Needs to be Included on a Workplace Label?

Workplace labels must contain the following key information:

Product Identifier (the product name).
Safe Handling Instructions (such as precautionary statements or pictograms).
A statement indicating that the SDS is available.

The system is built around three key rights for workers:

The right to know about hazards in the workplace.
The right to participate in health and safety decisions.
The right to refuse unsafe work.

Updating Labels

Labels must be updated when new information comes to light regarding the hazardous nature of the product. This update must occur within 180 days of the supplier becoming aware of the new data. Employers must then update workplace labels with this new information.

Final Safety Considerations

Always verify that labels are present and readable.
Read and follow all instructions on the labels and SDS.
Contact your supervisor if a label is missing, damaged, or unreadable.

By adhering to the labelling requirements outlined by WHMIS, both suppliers and employers can help ensure a safer working environment, reducing the risks associated with hazardous materials.
