The Workplace Hazardous Materials Information System (WHMIS) is Canada’s national hazard communication standard. The key elements of the system are cautionary labeling of containers of WHMIS “controlled products”, the provision of safety data sheets (SDS) and worker education and training.
As of July 1, 2015 WHMIS has been replaced with GHS, the Globally Harmonized System, also known as WHMIS 2015.
