What critical action must firefighters take after extinguishing a fire?

After extinguishing a fire, conducting overhaul to find hidden hotspots is a critical action that firefighters must take. This process involves carefully inspecting the area where the fire occurred to ensure that all embers and potential ignition sources are fully extinguished. Hidden hotspots can reignite a fire, posing risks not only to property but also to firefighters and the public.

During the overhaul phase, firefighters search for smoldering materials that may not be immediately visible. This includes checking behind walls, under floors, and in other concealed spaces where heat could linger undetected. By thoroughly carrying out this procedure, firefighters help ensure that the threat of re-ignition is eliminated, significantly improving safety for everyone involved.

Other actions listed, such as riding back to the station, leaving the scene, or seeking feedback from the public, do not address the critical need to ensure that the area is completely safe after a fire has been extinguished. These alternatives do not contribute to the necessary follow-up efforts required to protect property and lives.
