Starvation & Cooling

Starvation 

                                      Limitation or removal of fuel from the scene of fire is known as starvation. The extinction of fire by  starvation is applied in three ways.By removing combustible materiel from the neighbor hood of the fire. By removing the  fire from the neighbor hood of combustible material By subdividing the burning material.The smallest fire produced may be left to burnout easily rather than extinguishing

.Cooling

                                      limitation or removal of heat from the scene of fire is known as cooling. If the rate at which heat is generated by combustion  is less than the rate at which  it is dispersed  through  various agencies, the combustion cannot survive. There for the first step in cooling is to accelerate the speed with which heat is removed fro the fire. When the temperature of the burning mass  is reduced, the production of heat is also reduced.As heat flows from a hot body  to a cold body ,the cooling medium absorbs the heat from the fire.While pouring water on to the fire some of the water is converted to steam.The steam has produced helps to smothering.
