The Fire Tetrahedron is a model that illustrates the four essential elements needed for a fire to ignite and sustain. These elements are heat, fuel, oxygen, and a chemical reaction. Removing any one of these components will extinguish the fire, making the tetrahedron a useful tool for understanding fire prevention and safety. In fire safety, controlling these elements is crucial. For instance, using a fire extinguisher can eliminate heat or oxygen, while removing fuel can prevent a fire from spreading. Understanding the Fire Tetrahedron helps individuals and organizations develop effective fire safety plans and training.
