FLAMMABLE LABORATORY MATERIALS AND ITS HANDLING
¨ 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. When there is not enough air or oxygen, there is a hazard of asphyxiation (suffocation). ¨ Autoignition temperature – the flammable material which ignite on its own at a lowest temperature. ¨ Flashpoint — The low...
