Each, of the three classes above, will have many categories within that class.

Hazard Symbols and Pictograms:

  • There are many Pictograms that are associated with Hazards.
  • Hazard class names are changing
  • Some products that were not controlled under WHMIS may now be controlled.
  • WHMIS after GHS will not be less protective.

Supplier Label requirements:

  • Product Identifier
  • Signal words (NEW)
  • Hazard Pictograms
  • Hazard Statements
  • Precautionary Statements
  • Supplier Identifier

These supplier labels are still required to be in both French/English, Easy to read, and must be re labeled if the supplier label is not readable. The Hatched border previously used by WHMIS is no longer required.
