What does the term “overhaul” specifically refer to in firefighting operations?

Overhaul in firefighting operations specifically refers to the process of extinguishing a fire completely and ensuring that all hot spots are dealt with. This is a critical stage in firefighting because it involves searching for hidden fires that may not be visible but could potentially reignite, threatening both the safety of firefighters and the integrity of the structure involved. During overhaul, firefighters typically inspect the area, cool down any remaining embers, and use tools to dismantle structures as needed to reach potential hidden sources of fire. Proper execution of overhaul is essential to confirm that the fire is fully extinguished and to prevent fire re-flash or resurgence, thereby ensuring that the scene is safe.
