Another way to extinguish a fire is fuel removal. When it comes into contact with a fuel, it provides the energy necessary for ignition, causes the continuous production and ignition of fuel vapors or gases so that the combustion reaction can continue, and causes the vaporization of solid and liquid fuels. For this reason, the strategy is sometimes called a two-dimensional or 2D attack.
There are a of comparably serious heat-related risks, such as burns from hot gases e. The resulting self-sustained chemical chain reaction is complex and requires fuel, an oxidizer, and heat energy to come together in a very specific way.
