The Fire Triangle


    The fire triangle is a model for expressing the components of a fire. The three sides of the triangle show the three components needed to ignite and sustain a fire: heat, fuel, and oxygen.

    1. Heat

    This is perhaps the most essential of the fire elements. A fire cannot ignite unless it has a certain amount of heat, and it cannot grow without heat.

    1. Fuel

    A fire cannot begin if there is no material to burn. The fuel source can be anything that is flammable, such as wood, paper, fabric, or chemicals. Once the fuel element of the fire triangle is removed, the fire will go out.

    1. Oxygen

    The final element of the fire triangle is oxygen, which is also an essential component of fire. A fire needs oxygen to start and continue.

    If just one of these three components is removed, the fire triangle will collapse, and the fire will be extinguished.  It is worth remembering that essentially, fire extinguishers put out the fire by taking away one or more elements of the fire triangle, so it is well worth being prepared should the worst happen by having a fire extinguisher to hand!
