The fire triangle represents the fuel, oxygen and a source of ignition, heat or ignition source/energy-that must be present for combustion to occur.
For the fire to occur, all these sides are to be complete, otherwise the fire will not occur. so to extinguish fire any of the three viz. fuel, oxygen or the heat source should be removed or isolated.
Cooling: Removing the heat from fire to extinguish it ; eg : water type fire extinguisher does cooling.
Smothering: Cutting off the oxygen supply to fire or sealing off the oxygen not to reach the fire to extinguish fire; foam type fire extinguisher forms a blanket/film of foam layer disallowing air to reach thus extinguishes fire.
Starving: The fire and fuel; in this process all the adjacent burning material are removed from the scene of fire (or) the fuel supply value /knob is shut off or closed to avoid any further fuel available to continue / sustain burning, thus the fire does not have burning material to spread further, thus extinguishes due to starvation.
