In firefighting, what does "overhaul" refer to?

The term "overhaul" in firefighting specifically refers to the practice of searching for hidden fire embers and ensuring that all smoldering materials are completely extinguished. This important step occurs after the main fire has been brought under control and is critical to prevent re-ignition. During overhaul, firefighters meticulously check the areas surrounding the fire scene, using tools and thermal imaging to locate any remaining hot spots or embers that could reignite a fire.

While extinguishing a fire completely is a part of firefighting, overhaul goes beyond this initial stage by focusing on the thorough inspection of the scene. Assessing property damage and preparing incident reports are also crucial but are related to the aftermath of the firefighting process rather than the active firefighting and overhaul stage itself. Therefore, option B accurately captures the essence of what overhaul entails in the context of firefighting.
