I would laugh at him except my own checkered past has frightening tales of playing with gasoline and matches. Fortunately, God looks out for fools and little children and we escaped with only slightly singed eyebrows. When I look back on some of the unsafe adventures I have had with fire I am truly thankful for my good luck. Fire can be very dangerous if not handled properly and in the blink of an eye, something tragic can occur. That's why it's best to understand the nature of fire so you can use it safely.
Fire is actually a chemical reaction called the combustion chain reaction.
In this reaction, oxygen in the air binds with carbon and hydrogen found in fuel. The products that result are carbon monoxide gas, a small amount of water, and a whole lot of heat energy. All fire extinguishers or fire suppressing systems work by affecting these 3 elements of a fire. Once the water is squirted, it stops the fire by reducing the fire's heat and depriving it of oxygen. This class of extinguisher should only be used on ordinary fires which use wood or paper as fuel.
