3. 1. Workplace Hazardous Materials Information System (WHMIS)
Developed jointly by labor, industry, federal, provincial and
territorial governments.
A Canada-wide system designed to give employers and workers
information about hazardous materials in the workplace.
It applies to hazardous materials known as controlled products:
(Class A, B, C, D, E and F).
It does not apply to domestic products such as WD-40, for
example.

4. 1.1 OH&S Act and Regulation
Set out in detail employer duties respecting:
Labels
Material safety data sheet, and
Workers training
(all provinces and territories based their WHMIS on the same model to promote consistency across Canada)
WHMIS TRAINING REV.3

5. 1.2 Purpose of WHMIS
To provide information on hazardous materials used
in the workplace.
To facilitate the process of hazard identification in the
workplace.
To ensure consistency of hazard information in all
Canadian workplaces.

9. 2.1 Symbols Class A : Compressed Gas
Any material which is a gas at normal temperature (20 degrees) and pressure, but is packaged as pressurized gas, dissolved gas or gas liquefied by compression or refrigeration, e.g. oxygen, chlorine, acetylene, etc.
WHMIS TRAINING REV.3
15/06/01

10. 2.1 Symbols Class B: Flammable and Combustible Material
Class B: Flammable and Combustible Material solids, liquids and gases capable of catching fire or exploding in the presence of a source of ignition.
Examples: white phosphorus, acetone and butane. Flammable liquids such as acetone are more easily ignited than combustible liquids such as kerosene.
WHMIS TRAINING REV.3

11. 2.1 Symbols Class C: Oxidizing Material
Materials which provide oxygen or similar substances and which increase the risk of fire if they come into contact with flammable or combustible materials.
Examples: sodium hypochlorite, perchloric acid, inorganic peroxides.

12. 2.1 Symbols Class D: Poisonous & Infectious Materials
Class D, Division 1
Materials causing immediate and serious toxic effects. This division covers materials which can cause the death of a person exposed to small amounts.
Examples: sodium cyanide, hydrogen sulphide.
WHMIS TRAINING REV.3

13. 2.1 Symbols Class D: Poisonous & Infectious Materials
Class D, Division 2
Materials causing other toxic effects. This division covers materials which cause immediate eye or skin irritation as well as those which can cause long-term effects in a person repeatedly exposed to small amounts.
Examples: acetone (irritant), asbestos (carcinogen), toluene diisocyanate (sensitizer).
WHMIS TRAINING REV.3

14. 2.1 Symbols Class D: Poisonous & Infectious Materials
Class D, Division 3
Biohazardous infectious material.
This division applies to materials which
contain harmful microorganisms.
Examples: cultures or diagnostic specimens containing salmonella bacteria or the hepatitis B virus.
WHMIS TRAINING REV.3

15. 2.1 Symbols Class E: Corrosive Material
Acid or caustic materials which can destroy the skin or eat through metals.
Examples: muriatic aid, lye.
WHMIS TRAINING REV.3
15/06/01

16. 2.1 Symbols Class F: Dangerously Reactive Material
Products which can undergo dangerous reaction if subjected to heat, pressure, shock or allowed to contact water. Examples: plastic monomers such as butadiene and some cyanides.

17. 3. Supplier Labels
Supplier labels must be affixed to the original containers of controlled products.
If labels are missing or illegible, they should be replaced by workplace labels.
Eight (8) information in English & French: 1. Product Name (common/chemical name) 2. Hazard Symbol(s) 3. Hazards(s) 4. First Aid Measures 5. Suppliers Information (name, address, etc.) 6. Reference to MSDS 7. Precautionary Measures 8. Edge – must be distinctive & different from background of container.
Workplace labels must be affixed to controlled products that have been transferred from the original container into another container.

19. 4. MATERIAL SAFETY DATA SHEET (MSDS)
Material Safety Data Sheets (MSDS) must be obtained for all controlled products and available to all – All MSDS shall be dated less than 3 years old.
(Nine or more categories of information: (MSDS handout)
Product Identification and Use
The product identifier, use, manufacturer’s name, address
PIN number (product identification number)
Hazardous Ingredients
The terms 'hazardous Ingredient' refer to an ingredient that can cause harm to workers and other people, property or the environment through fire, explosion, reaction or release. These ingredients will be part of the product composition.

20. 4. MATERIAL SAFETY DATA SHEET (MSDS)
Physical Data State of the product - gas, solid, liquid, indicates how the substance may enter the body (inhalation, skin absorption, ingestion), the appearance, color, odor threshold, vapor pressure, vapor density, evaporation rate, boiling point, freezing point pH, specific gravity, coefficient of water/oil distribution. Fire and Explosion Data Conditions under which material may be flammable (ignite and burn readily), means of extinction, explosion data (explode as a result of being dropped or subjected to impact), sensitivity to static discharge, safe handling methods, flash point, auto ignition temperature, Upper Explosive Limit/Lower Explosive Limit.
