Classification is the process of determining which hazard class or classes apply to each product. The classification criteria that will be used by suppliers after GHS will be different than the current WHMIS criteria. Some classes may be even more extensive or comprehensive. WHMIS 2015 after GHS, hazards are arranged into three general groups containing hazards classes:

  • Physical hazards: 16 classes
  • Health hazards: 10 classes
  • Environmental hazards: 2 classes

The implementation of GHS will change WHMIS in many ways. It is very important that you start to get ready. You will need time to:

  • Understand the new requirements and assess the impact on your company’s operations.
  • Make plans to comply with the new WHMIS 2015 rules and obtain the required resources.
