FIRE TRIANGLE |
In order to understand how fire extinguishers work, you first need to know a little
bit about fire. Four things must be present at the same time
in order to produce fire:
Enough oxygen to sustain combustion,
Enough heat to raise the material to its
ignition temperature,
Some sort of fuel or combustible
material, and
The chemical, exothermic reaction that
is fire.
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add
in the fourth element, the chemical reaction, and you actually have a fire
"tetrahedron." The important thing to remember is: take any of these four
things away, and you will not have a fire or the fire will be extinguished.
Essentially, fire extinguishers put out fire
by taking away one or more elements of the fire triangle/tetrahedron.
Fire safety, at its most basic, is based upon the principle of keeping fuel
sources and ignition sources separate.
