Workplace Hazardous Materials Information System (WHMIS)
The Workplace Hazardous Materials Information System (WHMIS), Canada's hazard communication standard, came into effect on October 31, 1988. The key elements of the system are hazard classification, cautionary labelling of containers, the provision of (material) safety data sheets ((M)SDSs), and worker education programs.
