  1. The Science of Fire

  2. What we will learn today • We will talk about how the heat, fuel and oxygen, working together, cause a chemical chain reaction.

  3. We have already learned that: • It takes three things to cause a fire • Heat - something that is hot • Fuel - something that will burn • Oxygen - the air all around us • If we take any one of these things away, the fire cannot survive

  4. Webster’s dictionary • the active principal of burning, characterized by the heat and light of combustion • You or me • flames, heat and smoke • Fire Fighter • fast chemical reaction in which heat and light are produced and in which changes to oxygen take place. • What is the definition of fire?

  5. Fire results from a chemical reaction between two or more materials • changes the materials, which produces heat, flames and toxic smoke

  6. FIRE TRIANGLE Air Heat Fuel

  7. Oxygen - or the air all around us Fuel - or something that will burn • If you remove any one element, you prevent the chemical chain reaction that results from fire

  8. Removing Fuel • Education messages • good housekeeping practices • storage of flammable liquids • in approved containers • away from heat sources

  9. Removing Heat • Control of • smoking materials • matches and lighters • heating appliances • candles • Suppression • water cools a fire

  10. Removing Oxygen • Stop, drop and roll • Smothering action
