El Paso Fire Department (EPFD) Volume 3 Practice Exam

Extinguishment is the process of stopping a fire from continuing to burn. It involves cooling the fuel, removing heat, or removing the fuel or oxygen source, and applying the appropriate extinguishing agent to actually put the flames out. In practice, firefighters choose methods and resources—water, foam, dry chemical, etc.—to suppress the fire and prevent reignition. This is about ending the fire itself, not about evacuating occupants, reporting damages, or investigating the fire’s cause, which are separate activities. So the best definition is the act of putting out a fire using various methods and resources.
