What is the process of overhauling in firefighting?

Overhauling in firefighting refers to the thorough search for fire hotspots and potential fire spread areas after the main body of the fire has been extinguished. This crucial process is essential to ensure that all embers, smoldering materials, or hidden combustion sources are identified and dealt with, preventing reignition of the fire. It involves removing debris, checking for hidden pockets of heat, and using tools such as thermal imaging cameras or hand tools to locate any remaining hotspots. By performing an effective overhaul, firefighters can help mitigate the risk of flare-ups and ensure the safety of both the fire scene and surrounding structures.

The other options describe different aspects of firefighting operations but do not pertain to the specific process of overhauling. For example, extinguishing flames at their onset focuses on immediate response tactics, transporting equipment pertains to logistics and preparation, and setting up hoses relates to establishing an initial attack strategy. Each of these actions is important, but they serve different purposes in the overall firefighting operations, whereas overhauling specifically targets the remnants of a fire that needs attention after the main threat has been eliminated.
