What does "overhaul" mean in firefighting terminology?

In firefighting terminology, "overhaul" refers specifically to the process of checking for hidden fires and ensuring complete extinguishment. This crucial step comes after the main body of fire has been extinguished. Firefighters conduct overhaul to uncover any potential hotspots or smoldering materials that could reignite the fire.

During this phase, firefighters may displace furniture, open walls, or check void spaces where flames might have spread unnoticed. The goal is to prevent reignition and ensure that the scene is completely safe, which is vital for protecting property and lives.

Understanding overhaul is essential for ensuring comprehensive fire control and safeguarding structures after the initial response, making it a critical aspect of fire suppression operations. Other options do not capture the full scope and importance of this phase, focusing instead on actions that do not directly relate to the thorough follow-up needed to confirm that all fire risks are eliminated.
