What is WHMIS Training?

WHMIS means Workplace Hazardous Materials Information System. The system was designed to guarantee worker and employer safety in a work environment.

Since 1988, WHMIS symbols must be available at workplaces where hazardous materials are used or stored.

Participants who receive WHMIS training receive complete safety information on hazardous materials used in their workplace.


Why is WHMIS Training Important?

WHMIS training is essential for several reasons. Specification of responsibilities is a major reason why WHMIS training is essential for employees working in hazardous environments.

Suppliers must:whmis hazardous material symbols

  • Determine whether a product is a ‘controlled’ substance in line with WHMIS laws,
  • Label such products appropriately with corresponding WHMIS symbols, and
  • Provide material safety data sheets (MSDS) to consumers (the employer in most cases)

Employers must:

  • Establish training programs for employees tasked with handling hazardous material while at work,
  • Ensure products are labeled correctly, and
  • Check that MSDS documents are available for every product and are easily accessible by workers

Workers must:

  • Participate in training programs and use information gathered for safe handling of hazardous material,
  • Inform employers when labels are not available or unreadable on containers holding hazardous goods.

Suppliers, workers and employers had no specified responsibilities around hazardous materials before WHMIS regulation. But after its passing into law, everyone now has a role to play.

Requirements for WHMIS Training

The four (4) vital requirements for effective WHMIS training include:


Different levels of hazardous products exist and each one receives a classification with other materials within its range.

Trainees must receive extensive information on how hazardous materials should get their classification. The classification phase is vital for suppliers, employers, and workers tasked to handle such hazardous material.


Correct information must always be available to suppliers, workers, and employers to know what product receives what label. Mixing up labels could lead to damaging consequences, especially in industries where highly-reactive chemicals are used.

Material Safety Data Sheet (MSDS)

The Material Safety Data Sheet informs suppliers, workers, and employers about specific products. The products’ chemical composition, properties, precautions, etc. must be available in detail across these sheets.


Worker education is a vital reason why WHMIS training remains relevant. In this aspect of WHMIS training, workers undergo tests to determine if they can apply safety knowledge passed down while on duty.warehouse workers completing whmis safety training online
