Fire can be compared to a triangle. Three sides are necessary to make a triangle and three ingredients are necessary to cause a fire. These are heat, air, and fuel. If any one of these three sides is missing, there can be no fire.

Fuel

Fuel, the second side of the fire triangle, may be liquid, such as gasoline or solvents; a solid, such as paper or wood scraps; or a gas, such as propane.

Air

Air, the third side of the fire triangle, contains oxygen which is necessary to sustain a fire. Heat, fuel, and air must be in the proper proportion for fire to occur. Read more
