In live fire operations, what is meant by 'overhaul'?

Overhaul in live fire operations refers specifically to the process of searching for and extinguishing hidden fires that may not have been initially controlled during the initial attack. This is an important phase in firefighting, as it involves checking for embers or hot spots that could reignite the fire, which can occur in structural fires where flames have traveled through walls or floors.

During overhaul, firefighters carefully inspect the area, often removing debris and materials to ensure that all sources of heat or potential fuel are addressed. This step is vital in preventing rekindling, safeguarding both the structure and the safety of the occupants and firefighters.

The other options, while relevant to firefighting and fire operations, do not accurately define 'overhaul' in this particular context. Evaluating the effectiveness of training pertains more to assessing educational outcomes. Training personnel on new techniques focuses on enhancing skills and knowledge, but does not relate to post-fire actions. Conducting post-incident reviews involves analyzing the response and effectiveness of the firefighting efforts but occurs after the overhaul process is complete. Each of these aspects contributes to the overall firefighting strategy but does not encapsulate the specific meaning of overhaul.
