In eliminating the components of the triangle, you break the cycle of the reaction.

  • When you eliminate heat (ember, sparks and flame) there will be no further reaction with the fuel.
  • When you eliminate the fuel, the reaction ‘combustion’ doesn’t occur, combustibility is the major property of a fuel, this is simply the ability to burn well.
  • When you eliminate oxygen, by reducing the oxygen level you will end the reaction between the other two. Oxygen feeds the flame so in its absence combustion cannot occur. Fire requires about a minimum of 16% of oxygen.
