WebMar 31, 2024 · A tetrahedron is a 3D fire triangle. The extra point in the tetrahedron is the ‘chemical reaction’ ( combustion) that occurs when the three elements of the fire triangle are present in enough quantity. A chemical reaction (precisely an “exothermic” reaction) constantly occurs during a fire. WebAir contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. 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. The fire tetrahedron represents the addition of a component in the chemical chain reaction, to the three already present in the fire triangle. Once a fire has started, the resulting exothermic chain reaction sustains the fire and allows it to continue until or unless at least one of the elements of the fire is blocked.
