In firefighting, what does the term "overhaul" specifically refer to?

The term "overhaul" in firefighting specifically refers to the process of ensuring that no remaining hotspots exist after the main body of the fire has been extinguished. This is a critical phase of firefighting because it involves searching for hidden embers or smoldering materials that could reignite the fire. During overhaul, firefighters may dismantle certain structures or remove materials to check thoroughly for any remaining heat, which ensures that the fire is completely out and prevents the possibility of flare-ups.

In this context, the focus is on safety and preventing future incidents before leaving the scene. While analyzing fire origin and cause, clearing debris, and assessing structural integrity are important tasks in the firefighting process, they do not specifically capture the essence of what "overhaul" entails. Overhaul is concentrated on the post-extinguishment phase to guarantee that all potential dangers are addressed before the crew concludes their operation at the scene.
