Fire is a form of ignition. Fires start when a fuel is subjected to heat or another energy source, such as a match or a lighter. Fires are sustained by the further release of heat energy until all the combustible fuel is consumed. A fire is one of the most dangerous tools that one can come across. If ignited properly, it can consume anything and everything that comes in its way, including humans. Yet, fire on its own can be used to accomplish a great many tasks. A lot of inventions have been devised for the purpose of dealing with the incidence of fire. One of the most commonly used ones is the fire blanket. A Fire blanket are fire resistant sheets of material that are used incase of an emergency.
