The three elements of fire are fuel, heat, and oxygen. All of these elements must be present before it will thrive and spread out. Without any of these elements, for sure, fire will not materialize.
1. FUEL
Any kind of combustible material (wood, clothing, paper, chemical) characterized by its moisture content, size, shape, and its arrangement.
Once the fuel is removed, the fire will starve and be easily extinguished.
2. OXYGEN
Our atmosphere contains 21% oxygen. Most fire require only 16 % oxygen for the oxidation process to occur. When fuel burns, it reacts with oxygen from the surrounding atmosphere releasing heat and generating combustion products.
When oxygen is removed, the fire will be suffocated and out.
3. HEAT
This is responsible for the ignition of fire. It is needed to maintain the fire and spread it out by removing the moisture from fuel, warming the surrounding air, preheating the fuel path enabling it to travel fast.
Removal of heat is the most common type of suppression. In most cases, water is used to soak up heat generated by fire.
The interaction of each side of the fire triangle is required for the creation of fire. When not enough heat is generated, not enough fuel is available, and no oxygen is present, then no fire will be created. Fire can be prevented when each elements is properly isolated.
No one knows when fire will happen, yet it can be prevented by not allowing the three elements react with each other. Proper housekeeping is very important.
