Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction. A fire can be prevented or extinguished by removing any one of the elements in the fire triangle. There must be Heat (ignition temperature) to start and continue the combustion process. Going back to the fire triangle theory, fuel relates to heat in the way that different materials burn at different temperature, so some will require more and others less heat to ignite. When a wildfire rages out of control, firefighters can often put it out. there is a chemical combination of the oxygen in the air with woody material, Remove heat, oxygen or fuel and the fire goes out. Heat Heat is the first and most essential element that a fire needs. In certain cases such as some explosives, the oxidizer and combustible are the same (e.g., nitroglycerin, an unstable molecule that has oxidizing parts in the same molecule as the oxidizeable parts). The fire triangle, or combustion triangle, is the three components needed to ignite and sustain a fire. How hot is fire? Over time, combustible materials such as smoldering embers can reach their ignition temperature. There must be Fuel to burn. Wood is the typical kind of fuel for a fire. Grease fires may cause catastrophic injuries and extensive property loss. This cookie is set by GDPR Cookie Consent plugin. Three things are required in proper combination before ignition and combustion can take placeHeat, Oxygen and Fuel. Lets take a look at each of the 3 components. Extension cords should not be used with space heaters, since they generate an excessive amount of electricity and might potentially start a fire. For a fire to start, the three components must be combined in the correct proportions. without adult supervision. the combustion process itself), the ignition of additional fuel will continue as endobj What used to be taught was that the fire "triangle" consisted of 1 - Fuel, 2 - Oxygen, and 3 - Heat. Several examples include friction, as in the case of matches, heating an electrical wire, a flame (propagation of fire), or a spark (from a lighter or from any starting electrical device).
