What is the definition of overhaul in firefighting?

The process of overhaul in firefighting refers to the actions taken after the main body of a fire has been controlled or extinguished. During this phase, firefighters conduct a thorough examination of the fire scene to ensure that all remnants of the fire have been fully extinguished and that there are no hidden hotspots that could reignite. This process is critical because even after the visible flames are out, there may still be smoldering materials that can lead to a resurgence of the fire if not properly addressed.

Overhaul involves the removal of materials, checking for structural stability, and sometimes using thermal imaging tools to detect any remaining heat within walls or other concealed spaces. This step ensures the safety of both firefighters and any occupants returning to the premises, preventing further damage and ensuring that the fire does not restart.

In contrast to the options that discuss the initial attack on the fire, hazards checking, or restoration of the scene, overhaul specifically focuses on the meticulous process of ensuring complete extinguishment and securing the area once it is deemed safe from the dangers of rekindling.
