The fire triangle is composed of
1) heat
2) fuel
3) oxidizing agent (oxygen)
Types of fire extinguishers:
1) Water and Foam - extinguish the fire by taking away the heat element of the fire triangle. Foam agents separate the oxygen element from the other elements.
2) Carbon dioxide - extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge.
3) Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
4) Wet Chemical - extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements
5) Clean Agent - extinguish the fire by interrupting the chemical reaction of the fire triangle
6) Dry Powder - extinguish the fire by separating thefuel from the oxygen element or by removing the heat element of the fire triangle
7) Water Mist - extinguish the fire by taking away the heatelement of the fire triangle
8) Cartridge Operated Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle
