chemical chain reaction fire tetrahedron

chemical chain reaction fire tetrahedron

However, it does not explain the nature of the fire. The uninhibited chemical chain reaction portion of the tetrahedron is a complex set of chemical reactions that result in the rapid oxidation of a fuel, producing heat, light, and a variety of chemical by-products. Fire needs three things to burn (actually 4, but we will talk about that in a minute). Difference Between the Fire Triangle and Fire Tetrahedron. By removing the fuel, oxygen, or heat, or inhibiting the chemical chain reactions, a fire can be extinguished. Briefly describe the stages of fire from the ignition phase through decay. The fuels can exist in three types of matter: solid, liquid, and gas. Discuss heat, fuel, oxygen, and a chemical chain reaction (fire tetrahedron) and how it produces flaming (visible fire). Three elements must be present for for the fire to occur: heat, oxygen, fuel, and the chemical chain reaction. It includes the three components covered in the fire triangle, with the addition of a chemical chain reaction. The fire triangle is a simple means of illustrating the three requirements for the existence of fire. The fire tetrahedron is a slightly more complex model to describe the components needed to ignite and sustain a fire. Only gases burn. For a fire to take place, these four aspects must be brought together. Eventually, fire triangle has been updated to fire tetrahedron on addition of fourth element to the fire triangle i.e. Oxygen is in abundant supply for wildland fires. chain reaction. Further fire research determined that a fourth element, a chemical chain reaction, was a necessary component of fire. Summarize the benefits of fire protection systems in different types of structures based on fire behavior. It is often referred to as the "fire tetrahedron'. the fire tetrahedron is a four-sided geometric representation of the four factors necessary for fire: fuel (any substance that can undergo combustion), heat (heat energy sufficient to release vapor from the fuel and cause ignition), oxidizing agent (air containing oxygen), and uninhibited chemical chain reaction (sufficient exothermic reaction energy to produce ignition). The concept of fire was symbolized by the Triangle of Combustion and repres­ented, fuel, heat, and oxygen. This chemical reaction must produce sufficient exothermic energy to commence ignition. In particular, it does not include the chain reaction that results from chemical reactions among the fuel, oxygen, and heat. (the fourth is a chemical chain reaction and makes up the fourth side of the more advanced fire tetrahedron). The fire triangle was changed to a fire … The fire triangle was changed to a fire tetrahedron (pyramid) … The only difference is that the uninterrupted chemical chain reaction between the combustible, oxidizer, and thermal energy is represented as a distinct component, whereas it simply is implied in the overall construction of the fire triangle. These three things are oxygen, heat, and fuel. These make up the three sides of the fire triangle. Fire extinguishment is done by eliminating one of the variables of the fire tetrahedron. Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction. Further research discovered that a fourth element is required to sustain a fire – an uninhibited chemical chain reaction. This phenomenon is well known to hay farmers. Removal of any one of these essential elements will result in the fire being extinguished. A tetrahedron can be described as a pyramid which is a solid having four plane faces. The fire triangle was changed to a fire tetrahedron to reflect this fourth element. In particular, it does not explain the nature of the fire tetrahedron energy to commence ignition commence.
