In fire ground operations, overhaul is best described as

• A. The process of ensuring that a fire is completely extinguished and that no hidden fires remain.
• B. The rapid ventilation of a burning building
• C. The initial attack using a handline
• D. The securing of the scene for investigators

Answer: (A)

Overhaul is the phase after the main body of the fire has been brought under control, focused on locating and eradicating any remaining hidden fires. Fire can smolder in walls, ceilings, voids, and other concealed spaces, so crews perform a thorough search and remove debris or open structural areas to expose and extinguish these hotspots. The aim is to prevent rekindle and further damage by making sure nothing still smolders after the visible flames are out. This differs from rapid ventilation (which is used to clear smoke during the attack), the initial attack (which starts extinguishment with a handline), and scene securing for investigators (which happens once the fire is out and investigators arrive).
