Fire Chemistry:
To your knowledge, fire chemistry is a sequence of Earlier in this series of exothermic chemical reactions between a fuel and an oxidant accompanied by the by-products of combustion being; heat, smoke & electromagnetic radiation (light). Normally, there are four kinds of elements that are contributed to offering the right and précised environment for a fire to begin. The four major elements are-
· Fuel,
· Heat,
· Oxidant,
· and the Chemical Reaction (Oxidation).
The impactful elimination of any of these crucial components will result in the extinguishing of the fire. To put it simply, a portable fire extinguisher works by influencing, eliminating, or the ongoing effect of one or more of these four elements.
Classification of fires:
When it comes to the classification of the fire, it can be classified according to the type of fuel and whether electrical equipment is present there or not.
