Workplace Hazardous Materials Information System (WHMIS) is
an inclusive system for providing health and safety information on the safe use
of hazardous products used in Canadian workplaces. WHMIS has aligned with the
worldwide hazard communication system known as GHS - the Globally Harmonized
System of Classification and Labelling of Chemicals. Aligning with GHS provides
many benefits, including:-
- Hazard classification criteria are more comprehensive which improves ability to indicate severity of hazards.
- New hazard classes are included.
- Physical hazard criteria are consistent with the Transport of Dangerous Goods Act.
- Standardized language (hazard and precautionary statements).
- Standardized Safety Data Sheets (SDS) format and more comprehensive requirements.
- Educate and
train workers on the hazards and safe use of products.
- Ensure that
hazardous products are properly labelled.
- Prepare
workplace labels, as needed.
- Prepare SDSs,
as necessary (e.g., if an employer manufactures a hazardous product that
is used on-site).
- Provide access
to up-to-date SDSs to workers.
- Ensure
appropriate control measures are in place to protect the health and safety
of workers.
