What happens when you remove oxygen from a fire?

When you remove oxygen from a fire, you are effectively smothering the fire. This is based on the fundamental fire triangle, which consists of heat, fuel, and oxygen. A fire requires all three components to sustain combustion. By removing or reducing the availability of oxygen, you disrupt this chemical reaction, thereby preventing the fire from burning.

In practical terms, smothering a fire can be accomplished using blankets, foam, or other materials that deprive the flames of air. This is a common technique used in firefighting and is very effective, especially for small fires. The concept is crucial for anyone involved in fire safety as it highlights the importance of managing oxygen levels in controlling and extinguishing fires.
