Fire fighting

Firefighting is the act of extinguishing destructive fires.

A firefighter fights these fires and prevents destruction of life, property and the environment.

Firefighting is a highly technical profession which requires years of training and education to become proficient in.

Historically, physicists created a graphical representation detailing the three elements of fire (fire triangle).

In recent years, one more point has been added, creating the fire tetrahedron.

The four elements needed to sustain combustion are: fuel, oxygen, heat and a chemical chain reaction.

To extinguish a fire, it is necessary to remove one or more of the four components of combustion.

Removing any of these components of the fire tetrahedron will stop the other elements from interacting and not allow combustion to continue.

Firefighters work on limiting exposures (fuel that is in jeopardy of being ignited by nearby flame or from radiant heat), containing and extinguishing fire and then overhauling charred and burned debris from the affected areas as well as extinguishing all hidden fires to prevent a rekindle.
