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
