What is WHMIS classification?

WHMIS 2015 classification sorts hazardous products into two major hazard groups: physical hazards (like flammables, gases under pressure, and explosives) and health hazards (like acute toxicity, carcinogenicity, and skin corrosion). Each group contains multiple hazard classes, and products are further divided into categories based on severity, with Category 1 being the most dangerous.

What is WHMIS stand for?

WHMIS stands for the Workplace Hazardous Materials Information System. It is Canada's national standard for communicating information about hazardous products used, handled, or stored in workplaces. The system was first introduced in 1988 and updated in 2015 to align with the Globally Harmonized System (GHS).

How many pictograms are used in WHMIS 2015?

WHMIS 2015 uses nine hazard pictograms, though only eight are mandatory in Canada (the environmental pictogram is optional). Each pictogram features a distinctive symbol inside a red square border set on a point, including the flame, exploding bomb, skull and crossbones, and health hazard symbols.

What are the main components of a WHMIS Safety Data Sheet?

A WHMIS 2015 Safety Data Sheet (SDS) contains 16 standardized sections, including identification, hazard identification, composition, first-aid measures, firefighting measures, accidental release measures, handling and storage, and toxicological information. This format matches the GHS standard used internationally for consistent hazard communication.

Who is responsible for WHMIS training in the workplace?

Employers are legally responsible for providing WHMIS education and training to workers who may be exposed to hazardous products. Training must cover label and SDS information, safe handling procedures, and emergency response. Workers must be retrained whenever new hazards are introduced or workplace conditions change significantly.

What information must appear on a WHMIS supplier label?

A WHMIS 2015 supplier label must include six elements: product identifier, initial supplier identifier, pictogram(s), signal word (Danger or Warning), hazard statements, and precautionary statements. Labels on containers holding 100 mL or less may omit some elements but must still show the product identifier and pictogram.

What is the difference between a supplier label and a workplace label?

Supplier labels are applied by manufacturers or importers and contain all six required WHMIS elements in both English and French. Workplace labels are created by employers when products are decanted into secondary containers, and require only three elements: product identifier, safe handling information, and reference to the SDS.

When was WHMIS updated to WHMIS 2015?

WHMIS was updated in February 2015 to incorporate the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The transition period ended December 1, 2018, after which all suppliers, importers, and employers in Canada were required to fully comply with the new WHMIS 2015 requirements.
