What is the importance of a 'hot zone' time-lapse during overhaul?

Monitoring the hot zone with a time-lapse is essential because it captures how heat behaves after the fire is knocked down and helps detect rekindling before it becomes a bigger problem. Rekindling can hide in pockets of embedded embers, voids, or concealed fuels, and a continuous thermal record shows any hotspots that persist or reappear as the area cools. This information guides safe decision-making about when to proceed with salvage and overhaul, ensures that no hotspots remain before re-entry, and helps maintain air quality by confirming that heat, smoke, and combustion gases are diminishing and being vented properly. The other choices miss the safety-focused purpose or imply temperature data is irrelevant or only for paperwork, which isn’t accurate in overhaul work.
