The fire triangle or combustion triangle is a simple model

for understanding the necessary ingredients for most fires.

The triangle illustrates the three elements a fire needs to

ignite: heat, fuel and an oxidizing agent (usually oxygen).

A fire naturally occurs when the elements are present and

combined in the right mixture,[2] and a fire can be

prevented or extinguished by removing any one of the

elements in the fire triangle.

For example, covering a fire with a fire blanket removes

the "oxygen" part of the triangle and can extinguish a fire.

Class A

Class A Fires consist of ordinary combustibles such as wood, paper, trash or anything

else that leaves an ash. Water works best to extinguish a Class A fire.

Class B

Class B Fires are fuel by flammable or combustible liquids, which include oil, gasoline,

and other similar materials. Smothering effects which deplete the oxygen supply workbest to extinguish Class B fires.

Class C

Class C Fires. Energized Electrical Fires are known as Class C fires. Always de-

energize the circuit then use a non-conductive extinguishing agent. Such as Carbon

dioxide.

Class D

Class D Fires are combustible metal fires. Magnesium and Titanium are the most

common types of metal fires. Once a metal ignites do not use water in an attempt to

extinguish it. Only use a Dry Powder extinguishing agent. Dry powder agents work by

smothering and heat absorption.

Class K

Class K Fires are fires that involve cooking oils, grease or animal fat and can beextinguished using Purple K, the typical agent found in kitchen or galley extinguishers.
