MODUL 6 FIRE Most workplaces provide fire training for a certain number of employees. An untrained should not try to put out a serious fire. When there is a fire, most people are frightened. Workers must know the correct fire drill, or what they should do, if there is a fire. Most workplaces have written fire instructions. These instructions should be on the wall beside the fire extinguishers and fire exits. Solid materials Solid materials like wood, rags and paper can burn easily. If the fire is small, it may be extinguished with water or with sand. Water lowers the temperature of the burning material. Sand stops air from reaching the fire. Nothing can burn without oxygen. Air contain oxygen. The main danger of most small fires is that they can quickly spread. Small fires can sometimes be contained, kept under control, by: 1. shutting doors (cutting off oxygen supply to the fire); 2. removing nearby materials such as paints, timber, gas cylinders, oil drums, petrol, etc. A fire needs fuel, heat and oxygen. Remove any one of these, and the fire will be controlled. Liquid materials http://www.mercubuana.ac.id

Most fires can be prevented Most fires can be prevented. The following rules will help to prevent fires: 1. Do not leave rubbish lying around. The safest place for rubbish is in a metal bin with a lid. If there are bins, use them. 2. Do not leave upon tins or drums of oil, solvent or paints standing around. Many industrial liquids are volatile. Their vapour can be inflammable or explosive. 3. Matches, cigarette ends, hot ashes and hot metal can all cause fires among paper, rag or wood shavings. 4. Leave electrical repairs to the specialist. If a fuse has to be repaired or replaced, never use thicker wire. http://www.mercubuana.ac.id
