What is the purpose of a "hot spot" during firefighting?

The term "hot spot" in firefighting specifically refers to an area where the fire is still burning or smoldering. These zones can be critical to monitor and address, as they indicate the potential for reignition of flames or the spread of the fire. Identifying hot spots is essential for firefighters as it allows them to focus their efforts on extinguishing lingering embers or residual heat that could reignite a controlled area. Safety and control of a fire situation depend on effectively addressing these hot spots to prevent further fire growth.
