Workplace Hazardous Material Information System

WHMIS (or Workplace Hazardous Materials Information System) - pronounced "WHIM-ISS" - is Canada's national hazard communication program for hazardous workplace chemicals. Established in 1988, WHMIS was developed (and continues to evolve) through a well-established consensus process in partnership between Canada's federal, provincial and territorial (F/P/T) governments, as well as with individuals representative of Canadian industry (i.e., suppliers and employers) and organized labour.
