EXTINGUISHING FIRE
Fire can be controlled and extinguished by an interruption in the supply of one or more of the three elements of the fire triangle. By removing or eliminating one side of the triangle (fuel, Oxygen or Heat ), you can extinguish the fire.
Cool the burning material ( remove heat).
Remove the fuel ( stave the fire).
Exclude oxygen (smother the fire).
Break the chemical reaction.
COOLING
The most effective way to reduce the temperature of a fire is to apply water to it.
CAUTION: Never apply water to fires involving flammable liquids or energized electrical types of equipment.
REMOVE FUEL
Removing the fuel source effectively extinguishes the fire.
EXCLUDE OXYGEN
In its simplest form, this method is used to extinguish range top fires, A cover is placed on a pan of burning grease, starving the fire of oxygen and thus extinguishing it.
BREAK THE CHEMICAL REACTION
Certain fire extinguishers expel an agent that interrupts the chemical chain reaction, thus extinguishing the fire.
