A fire extinguisher is an operation to extinguish and control a fire. The purpose of this is to protect the health of people and prevent damage to their property. During a fire, the most important thing is to prevent the fire from spreading and how to extinguish it. The pyramid of fire is composed of flammable substances or chain reactions, oxygen and heat, which, if one of these factors can be controlled or controlled, will suppress the fire. General methods of fire control include chilling and strangulation, eliminating or obstructing flammable substances and controlling chain reactions.
Cool the fire
It is one of the oldest and most effective methods for controlling fire and cooling fires. Carbon dioxide water and gas are used for this purpose, and the amount and method of their use plays an effective role in the control of fire.
Choke the fire
Fire suppression means covering the surface of the fire with special materials to prevent oxygen from reaching the fire area. Although not effective for controlling all fires, it is a good method for most fires. The materials used to suppress the fire must be covered and heavier than air.
Eliminate and create a barrier to flammable materials
At the beginning of the fire, the material can be prevented by spreading the material, removing the non-flammable materials, creating a retaining wall, or diluting the flammable liquid.
Controlling Chain Reactions
Chain reactions can be controlled by using halo compounds and some solid compounds such as baking soda. This method is more expensive and costly than other methods, but it can be considered a complement to valuable materials.
