What does 'overhaul' involve in firefighting terms?

In firefighting, 'overhaul' refers specifically to the process of searching for and extinguishing hidden fires after the main fire has been knocked down. This phase of firefighting is crucial because fires can often smolder or hide within walls, ceilings, or other structures, posing a risk of rekindling. During overhaul, firefighters systematically check for hot spots and ensure that the area is completely safe by using tools to break apart materials that might be concealing embers or flames. This comprehensive approach prevents re-ignition and ensures that the fire is fully extinguished, which is essential for the safety of both firefighters and the affected property.

Other options do not align with the technical definition of 'overhaul' in firefighting. Introducing new firefighters pertains to staffing and personnel management rather than the extinguishment phase. Reassessing the incident command is about the organizational structure during a response, and maintaining equipment post-incident is related to operational readiness, neither of which directly supports the definition of overhaul.
