Fire Tetrahedron

The fire tetrahedron is a model that explains how fires start and sustain. It shows four essential elements: heat (enough energy to ignite), fuel (material that burns), oxygen (needed for combustion), and a chemical chain reaction (the ongoing process of fire). Removing any one of these elements can stop a fire. For example, cooling removes heat, smothering cuts off oxygen, and removing fuel extinguishes its source. Understanding this helps in fire prevention and control by targeting the necessary components to extinguish or prevent fires effectively.
