What is the process of extinguishment?

• A. The act of putting out a fire using various methods and resources.
• B. A report of fire origin.
• C. A plan for evacuations.
• D. A method of securing utilities.

Answer: (A)

Extinguishment is the deliberate act of putting out a fire by removing one or more sides of the fire triangle—heat, fuel, or oxygen—through cooling, starving, or smothering the flames. In practice, firefighters apply the right methods and resources, such as water or extinguishing agents, and use tactics like direct cooling with hose streams or smothering and ventilating as needed, to achieve a safe, complete extinguishment. The other actions describe different stages or tasks at an incident (investigating origin, planning evacuations, or securing utilities) and are not the act of putting the fire out.
