3. Properties of a Fire
 Fire safety, at its most basic, is based upon the principle of keeping fuel sources and ignition sources separate. 
Three things must be present at the same time to produce fire which is a Chemical chain reaction :
1. Enough oxygen to sustain combustion.
2. Enough heat to reach ignition temperature.
3. Some fuel or combustible material.
12/07/2006 Rev B

4. Properties of a Fire continued
These three elements form the fire triangle that is necessary for a fire to burn. Together, they produce the chemical reaction that is fire. Take away any of these things and the fire will be extinguished.
