Methods of extinguishing fires

Theory is based on the dimensions of fire one or more of the three elements mentioned above for the updated fire, that is based on the theory of fire break by removing a triangle ignition ribs or all of the ribs and therefore are subject to fire three methods are: -

First, cooling the fire
And is intended to reduce the temperature of burning, using water which is thrown on the fire and adopt this method mainly on the ability of water absorption to the heat of material burning fire, and find water when it is used for cooling purposes two types of changes, it gets hot until it reaches its boiling point and turn to vapor above the surface of the fire, and serve to mute the fire of oxygen decrease the proportion of air.


Second, choke the fire
Stifle the fire is covered barrier prevents access to air and oxygen by the following means: -

 close ports and vents the fire place to reduce the proportion of oxygen in the air to the percentage that do not permit the continuation of ignition

 - cover burning Article Foams chemical.

 - replace oxygen with water vapor or carbon dioxide or dry chemical powders or vapors of halogens.

 - fire extinguishers can separate the flame from burning material on fire, by blowing up the fire place with explosives Caldinamet, this method is usually used to extinguish fires, oil wells.


Third:  starve the fire
Starve the fire is to reduce the amount of flammable materials in the following ways: -
 the transfer of goods and materials available place the fire away from the influence of heat and flame, such as the withdrawal of flammable liquids from tanks located by the fire, or transportation of goods from within the stores at risk and the heat of the fire, or remove plants and trees, agricultural land to stop the flow and the spread of the fire.


 - remove and remove flammable materials into flames away from flammable neighborhoods at risk of flame and heat such as the withdrawal bales of cotton in which the fire burning from within the storage place to another place does not display risk neighborhoods

 - close valves flammable gases.

 - the division of the burning materials into small pieces to be set small fires can be controlled such as roads for wood burning to fragment into small pieces or particles of the water surface mixing flammable liquids.
