The fire tetrahedron represents the addition of the chemical chain reaction to the three already present in the fire triangle. Combustion is a chemical reaction that feeds a fire more heat and allows it to continue. Once a fire has started, the resulting exothermic chain reaction sustains the fire and allows it to continue until or unless at ...
Each component represents a property necessary to sustain fire: fuel, oxygen, heat, and chemical chain reaction. Extinguishment is based upon removing or hindering any one of these properties. Fire triangle: An outdated model for understanding the major
The Fire Triangle Fire Triangle. Main article: Fire Triangle. A simple model that illustrates the three necessary ingredients needed to ignite most fires: heat, fuel, and an oxidizing agent (usually oxygen). [12] A fire naturally occurs when all of these elements are present and combined in the right mixture, [13] meaning that fire is actually ...
A fire burns due to the presence of three elements: fuel, oxygen and heat. This is often referred to as the fire triangle. Sometimes it is known as the fire tetrahedron if a fourth element is added: a chemical chain reaction which can help sustain certain types of fire. The aim of firefighting is to deprive the fire of at least one of those ...
Fire control is the practice of reducing the heat output of a fire, reducing the area over which the fire exists, or suppressing or extinguishing the fire by depriving it of fuel, oxygen, or heat (see fire triangle). Fire prevention and control is the prevention, detection, and extinguishment of fires, including such secondary activities as ...

The problem in coming up with any kind of accurate consensus reaction, he says, is that “during the electric set, the microphones were turned way down because the amps were so loud on stage, so ...
