The Fire Triangle & Sprinklers

The Fire Triangle

The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for a fire. 
The triangle illustrates the three elements a fire needs: heat, fuel, and an oxidizing agent usually the oxygen in the air. If a fire occurs then it will rapidly spreads when these elements are all present. A fire can be prevented or extinguished by removing any one of the elements in the fire triangle.

A fire sprinkler reduces the “oxygen” part of the triangle and also controls the heat and smoke. In a building this enables occupants to escape safely, stops the fire spreading and can often totally extinguish the fire.

How Fire Sprinklers Work

Fire sprinklers are triggered by the air around the sprinkler head in the room reaching a certain temperature. Usually the temperature to trigger a residential sprinkler is 56oC.  Heat of 63oC is required to trigger fire sprinklers in larger warehouses where lots of heat is generated and you wouldn’t wish the sprinkler to activate accidentally.

Inside each sprinkler head is a small frangible glass bulb containing a chemical liquid. When this liquid heats up it expands and pops the glass and this sets off the sprinkler.
