It is essential to take safety measures, including storing combustible materials in a secure area and keeping paper and fabric stacks away from possible heat sources. Decay: once you stop feeding the fire with fuel, the fire will enter the decay stage and start to burn down. We hope that brushing up on your school knowledge of the fire triangle and the three elements of fire has helped you understand fires, fire prevention and fire extinguishing better. Combustion is defined as rapid oxidation producing light and heat flames. It occurs when matter conveys heat without visible movement of the matter itself. It is lower than the material's autoignition temperature. The fire triangle, also known as the combustion triangle, is a model designed to provide a simple, visual way to remember the main factors needed for the chemical reaction we call fire (yes, fire is a chemical reaction, not a thing) to take place. Scraping embers from a burning structure also removes the heat source. The fire triangle is a simple way of understanding the elements of fire. before ignition and combustion can take place---Heat, Oxygen and Fuel. How hot is fire? Do You Get Charged When The Fire Department Comes? This process is halted by the application of water, since water is more easily evaporated than the fuel is pyrolyzed.
