created to fulfill workplace obligations to let Canadian workers know
about potential safety and health hazards associated with the materials
or chemicals they use at work. Exposure to hazardous materials can cause
or contribute to serious health issues.
These issues can include effects on the nervous system, kidney or lung damage, and sterility, cancer, burns and rashes. Some hazardous materials can cause fires or explosions. WHMIS was created to help prevent injuries, illnesses, and deaths and associated medical costs, and property damage from explosions and fires caused by hazardous materials.
