Classification of Controlled Products
After completing this section, trainers will
understand the 6 classes of controlled products and relate the 8 hazard symbols to the correct
classes,
be able to describe the groups of exemptions, and
be able to explain responsibilities for classification.
WHAT ARE CONTROLLED PRODUCTS?
Controlled products are defined as those materials which meet the criteria for inclusion in 1 or more of
the 6 hazard classes. The 6 classes of controlled hazards are:
1. Compressed Gas
2. Flammable and Combustible Material
3. Oxidizing Material
4. Poisonous and Infectious Material
5. Corrosive Material
6. Dangerously Reactive Material
Controlled products include a wide range of chemical substances, as well as some biohazardous
materials. Some may be pure substances (such as chlorine gas) while others may be mixtures of
chemicals.
For example
ABC solvent could contain a blend of toluene, acetone,
kerosene and butyl cellusolve.
The federal legislation establishes the criteria and describes tests taken to determine if a substance
meets the criteria for a controlled product. If a material meets the criteria for 1 or more of the 6 hazard
classes, WHMIS requirements apply. If a material does not meet any of the criteria, the WHMIS
requirements do not apply.
There is no list of controlled products. The only way of knowing if a material is a controlled product is to
compare the properties of the material to the criteria. See Ingredient Disclosure List on page 9.
