Why does smothering the fire stop the reaction?

When a wildfire has started, we try to remove the oxygen side of the triangle by smothering the fire with a fire retardant, foam, dirt or water in a fine spray or fog. They will replace the oxygen around the fuel affecting one side of the fire triangle. They reduce heat as well as supply of oxygen to the fuel.

How does oxygen react to a flame?

Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.). This process is known as oxidation.

What happens to oxygen after burning?

Fire does use oxygen when it burns. But it also produces carbon dioxide. An oxygen molecule has two oxygen atoms in it. If you heat the air in the jam jar with a candle burning inside, the air expands and becomes less dense, and some air molecules leave the jar.

How does the fire triangle work?

The fire triangle, or combustion triangle, is the three components needed to ignite and sustain a fire. The three ingredients of a fire triangle are; heat, fuel and oxygen. If just one of these components is removed, the fire triangle will collapse and the fire will be extinguished.
