¨      Chemicals and hazardous substances that can easily ignite and burn rapidly ¨      It may be in any form – solids, gases and liquids. ¨      Liquids and gases acts as combustible materials. ¨      Solids may catch fire when it is nearby with heat, heat acts as an ignition sources. ¨      Oxygen is an important requisite to ignite flame ¨      Flammable gases such as carbon monoxide and hydrogen sulphide are toxic at very low concentrations. ¨      Most vapours from flammable liquids are heavier than air and will accumulate near the ground. They can displace the air.
