Class A: Compressed Gas

Back 9

Class A materials:
-pose an explosion danger because the gas is being held in a container under pressure;
-may cause its container to explode if heated (such as what would happen in a fire);
-may also cause its container to explode if dropped.

When handling Class A materials you should:
-handle with care, do not drop container;
-keep container away from potential souces of ignition;
-store the container in designated areas.

Examples of Class A materials: gas cylinders for oxyacetylene welding or water disinfection.

Class B: Flammable and Combustible Material

Back 10

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.
