What is the primary function of searching for hidden fires during overhaul?

The primary function of searching for hidden fires during overhaul is critical for ensuring that no embers, hotspots, or smoldering materials are left behind that could reignite and cause a resurgence of the fire. This process is known as overhaul, which involves thoroughly checking the affected area to identify hidden sources of combustion.

During overhaul, firefighters systematically check and ensure that all pockets of heat or fire are fully extinguished. This is paramount because any remaining heat source can lead to harmful fire relapses, risking not only the safety of personnel but also the potential for property loss and extension of the incident. Understanding the thoroughness required in this stage helps to cement the idea that ensuring everything is cool to the touch is a protective measure beyond just managing the immediate aftermath.

While functions like rescuing victims, preventing fire spread, and ensuring structural integrity are important aspects in the progression of firefighting operations, they are not the central focus during the overhaul phase. The emphasis during overhaul remains on completely eliminating the threat of fire re-ignition, which is why this choice aptly describes the function of searching for hidden fires.
