What is the act of extinguishing or controlling a fire known as?

The act of extinguishing or controlling a fire is known as fire suppression. This term specifically refers to the techniques, tools, and processes used by firefighters and first responders to manage and eliminate unwanted flames. Fire suppression includes a variety of strategies such as using water, foam, or other agents to reduce the heat or starve the fire of oxygen. It is a critical aspect of firefighting aimed at protecting life, property, and the environment from the destructive effects of fire.

In contrast, other choices relate to different aspects of fire management. Fire investigation involves the examination of a fire scene to determine the cause and origin of a fire, which is distinctly different from actively suppressing one. Fire ignition refers to the process by which a fire starts, focusing on the conditions that enable combustion to occur. Fire prevention encompasses practices designed to reduce the likelihood of fire starting in the first place, such as public education, regular maintenance, and compliance with fire codes. Each of these plays an essential role in overall fire safety, but they do not directly involve the act of extinguishing or controlling a fire.
