CLASSIFICATION

WHMIS requires the manufacturer of a hazardous material to classify the material according to its inherent physical properties into one or more of 6 hazard classes.



17

CLASS A: COMPRESSED GAS

A compressed gas is a material that is normally in the gaseous form at room temperatures.

Hazards:• Explosion, Projectile• Frost BitePrecautions:• Store securely, upright

and away from sources of heat

• Do not puncture• Protect valves



18

CLASS B: FLAMMABLE & COMBUSTIBLE

Class B is sub-divided into 6 divisions:

1. Flammable Gases

2. Flammable Liquids

3. Combustible Liquids

4. Flammable Solids

5. Flammable Aerosols

6. Reactive Flammable Materials



19

CLASS C: OXIDIZING MATERIALS

Oxidizing materials cause/contribute to the combustion of other materials. Hazards:• Fire• Fire burns more

vigorouslyPrecautions:• Keep away from

incompatible materials and flammable or combustible materials



20

Hazards:• Thermal burns Respiratory

irritation or damage

Precautions:• Use appropriate ppe• Avoid incompatible materials

or conditions
