1) Cooling Method:
The method, in which Heat of burning material/substance is
removed, generally by using water, is known as cooling method. Water brought
the heat of substance under Fire below the ignition temperature of materials.
This method is normally applied in extinguishing Fire of solid combustible
materials.
This method must not be adopted for fighting live
electrical Fire. This method is applied for extinguishing electrical originated
Fire only after ensuring the cut off of power supply.
2) Smothering Method:
The method in which Oxygen is removed from burning
materials is known as smothering method. In this method oxygen is restricted to
Fire by using layers of Foam or inert gases like CO2, Nitrogen, Chlorofluoro
carbon or Dry Chemical Powder or Dry sand. Sometimes this is achieved by proper
blanketing of Fire using Fire blanket or Aluminum blanket
or other available non-combustible materials. This method is normally used for
extinguishing Fire in Flammable liquids.
3) Starvation Method:
The method in which Fuel or combustible material is
removed from Fire is known as starvation method. This is achieved by removing
burning substance from the scene of Fire. Fire in pipe lines, cylinders,
Tankers containing flammable liquid or gas is controlled by closing the valves.
By closing valves the Fuel or combustible materials are isolated from Fire and
thus starvation is achieved. This method is best used for extinguishing Fire in
pipelines, cylinders containing flammable liquid or gas.
