Fire Fighting Flashcards
What are the 3 elements that form combustion?
- Heat
- Oxygen
- Fuel
What methods can be used to remove an element from the fire triangle?
- Starvation: Remove fuel source
- Boundary cooling: Stop temp rising, keep steel wet
- smothering: Reduce oxygen below 9%
- Cooling: Saturate with water to lower fuel temp below ignition temp
- Boundary starvation: Remove fuel from the surroundings
- Flame inhibition: Breaks the chain reaction between elements
