What best describes the purpose of overhaul?

• A. To thoroughly search for and extinguish hidden fires and to prevent rekindle
• B. To ventilate the space only
• C. To initialize the incident command
• D. To inspect for safety hazards outside the building

Answer: (A)

Overhaul is about finishing the fire attack by finding and extinguishing hidden fires and smoldering materials to prevent rekindle. After the main flames are out, heat can hide in walls, ceilings, attics, and other void spaces or among burned debris. Firefighters perform a thorough search of these areas, open up structure components as needed, and directly cool or extinguish hotspots to ensure nothing remains that could reignite. They may remove burned contents to access hidden fires or use thermal imaging to spot heat behind surfaces. The aim is to eliminate all heat sources and fuel that could cause the fire to restart. This step is not primarily about ventilating the space, initializing incident command, or inspecting outside hazards, which are addressed in other parts of the incident.
