In general, oxygen is necessary for combustion (the chemical process that produces fire). Yet, how fire works and how to extinguish a fire are things youve probably learnt a long time ago when you were preparing for your GCSEs it all comes down to the principle of the fire triangle. A fire can be prevented or extinguished by removing any one of the elements in the fire triangle. If you have fuel and fresh air for example, but not enough heat to ignite and sustain it, your fire will go out. These elements constitute the fire triangle. All these three - fuel, Oxygen, and heat are required for combustion to take place. Combustion; fuel; oxygen. That iswhy one recommendation for extinguishing a small fire is to smother it with a non-flammable blanket, sand or dirt. Three Elements of the Fire Triangle Oxygen Oxygen is usually required for combustion (the fires chemical reaction) to occur. Once the fire is ignited, the process of oxidation continues and it happens so fast that it produces enough energy (heat) to sustain and spread the fire until all sources of fuel have been consumed by the flames. If all sides are connected then fire occurs. Oxygen can be denied to a fire using a carbon dioxide fire extinguisher, a fire blanket or water. Most of us will be aware of the fire triangle from those school science lessons. They reduce heat as well as supply of oxygen to the fuel.
