WHMIS is the "Workplace Hazardous Material Information System"
Class B: Flammable and Combustible Material
This class includes solids, liquids and gases capable of catching fire or exploding
in the presence of a source of ignition.
Class B materials:
will burn and are therefore potential fire hazards.
may burn at relatively low tempertaues; flammable materials catch fire at lower temperatures than combustible materials.
may burst into flame spontaneouly in air or may release a flammable gas on contact with water;
may cause a fire when exposed to heat, sparks, or flames or as a result of friction;
When handling Class B materials you should:
keep the material away from heat sources and other combustible materials;
never smoke when working with or near the material;
store the containers in designated areas.
Examples: white phosphorus, acetone and butane. Flammable liquids such as acetone are more easily ignited than combustible liquids such as kerosene.
