- A general rule is that three elements of Fuel, Oxygen and Fuel need to be combined if a fire is to survive.
- By removing any one or more of these three elements than a fire will be extinguished.
- Some fire systems remove oxygen thus suffocating the fire. (C02)
- Others cool the heat so that the fire is dowsed. (Water, Halo-Carbons)
- Finally a fire will self extinguish if the fuel burns out.
