For any fire to occur, there must be combustible substance to keep the fire continuously alive. This substance is called fuel. When the fuel becomes depleted, the fire dies a silent death. However, if the fuel is left alone, undisturbed, it cannot start burning. Something must change the stable condition of the fuel which results in a chemical reaction called fire. That thing is heat which is called the source of ignition. Everything has its comfortable operating environment, including fire. The above two conditions availability of fuel and source of ignition cannot result in fire unless there is an environment with sufficient air (oxygen). Fire is a chemical reaction, and for it to occur, the three conditions stated must be present and in required quantities. This course intends to enhance the knowledge of the participants to methods of reducing any of the three conditions thereby preventing the occurrence of fire in buildings or factories.
