Methods of Extinguishing Fire OSHMS360
To stop a combustion reaction, one of the three elements of the fire triangle must be removed. Without sufficient heat, a fire cannot begin, and it cannot continue. Heat can be removed by the application of a substance which reduces the amount of heat available to the fire reaction. This is often water, which absorbs … See more The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent See more The oxidizer is the other reactant of the chemical reaction. In most cases, it is the ambient air, and in particular one of its components, oxygen (O2). By depriving a fire of air the fire can be extinguished, such as when covering the flame of a small candle with an … See more In the context of wildland fire, the fire triangle can be scaled up to apply to fire spread over landscapes (scales of days and several kilometres) and recurrence of fire over time (scales of decades and hundreds of kilometres). Thus, while heat is important to ignite … See more The fire tetrahedron represents the addition of a component in the chemical chain reaction, to the three already present in the fire triangle.
