What does 'overhaul' mean in firefighting?

In firefighting, 'overhaul' refers specifically to the process of inspecting the scene after the main fire has been extinguished to ensure that all remaining hot spots and embers are fully extinguished. This step is critical because even after the visible flames are gone, smoldering materials can reignite and cause a flare-up if not properly addressed. During the overhaul process, firefighters typically go through the area methodically, often using tools to dismantle structures or move debris to check for hidden fires within walls, ceilings, or other concealed spaces.

This detailed inspection helps to ensure the safety of both firefighters and the public by preventing the possibility of rekindling. It is an essential aspect of wildfire and building fire suppression, emphasizing the importance of thoroughness and vigilance in fire prevention and safety protocols.
