Class B: Flammable and Combustible Material
Class C: Oxidizing Material
Class D: Poisonous and Infectious Material

Class E: Corrosive Material
Class F: Dangerously Reactive Material Division 1 – Materials causing immediate and serious effect
Division 2 – Material causing other toxic effects
Division 3 – Biohazardous infectious materials WHMIS Labels All WHMIS controlled products must be labelled.

There are 2 types of WHMIS Labels: Other Means of Identification include: Supplier Labels

Supplier Label Content (for containers less than 100 ml)

For small containers of 100 ml or less in size, supplier labels need only display four categories: the product identifier, supplier identifier, a reference to the MSDS, and hazard symbols. Workplace Label Other Means of Identification In certain cases, workplace labels need not be used. Other means of visual identification will do, such as product names, colour or number codes, placards, and even piping diagrams. These other means must be used in combination with worker education to ensure that workers are able to identify contents.

Other means of identification may be used to identify: Locations where workplace hazardous waste produced in the workplace are stored

Controlled product transfer systems such as pipes or conveyor belts

The contents of reaction or process vessels

The contents of portable containers that are filled directly from a labelled container and will be under the control of the worker who transferred the product to the new container for use on the same shift. a)
