In the context of fire suppression, what does "overhaul" refer to?

In the context of fire suppression, "overhaul" specifically refers to the process of re-examining the area for hidden hot spots. This is a critical step that occurs after the main phase of firefighting is completed and the visible flames have been extinguished. During overhaul, firefighters utilize thermal imaging cameras and other tools to search for any remaining embers or areas that may reignite, ensuring that the fire is fully extinguished and that there are no hidden dangers left that could cause the fire to flare up again.

This phase is essential for preventing rekindling, which can not only endanger the safety of firefighting personnel but also jeopardize property. By thoroughly checking the affected area, firefighters can confirm that all parts of the fire have been addressed, which contributes to effective fire suppression and safety.
