How does PBCFR define "fire suppression"?

The definition of "fire suppression" as the act of stopping a fire from spreading and causing further damage reflects the primary goal of firefighting efforts. This process encompasses various tactical methods employed by firefighters to control and extinguish fires to prevent them from escalating and inflicting greater destruction. Fire suppression involves techniques such as directly applying water or other extinguishing agents to the flames, creating firebreaks, and employing controlled burns to eliminate fuel sources.

In contrast to other options, evacuating residents pertains more to rescue and safety procedures rather than suppression. Investigating fire causes is crucial for understanding fire safety and prevention, but it does not directly involve extinguishing fires. Coordination of emergency response encompasses a broader range of activities, including communication and logistics but does not specifically define the act of fire suppression itself. Thus, option B accurately captures the essence of fire suppression in the context of firefighting activities.
