What is a sign to look for during overhaul when assessing fire damage?

During overhaul, assessing fire damage involves looking for key indicators that signify the presence of hidden fire or smoldering materials. Smoke seeping from cracks is a critical sign to observe. It suggests that there may still be combustion occurring in hidden areas, which can lead to reignition or further damage if not addressed.

Identifying smoke is crucial because it aids firefighters in determining the extent of the damage and the effectiveness of their extinguishment efforts. When smoke is present, it indicates that there is likely still heat and potentially hazardous materials nearby, necessitating further investigation and action to ensure the area is fully extinguished and safe.

In contrast, intense rain, bright sunlight, and strong winds are environmental factors that do not provide direct insight into fire damage or the presence of residual heat and smoke after extinguishment has occurred. These elements do not indicate potential hazards in the aftermath of a fire and therefore are not reliable signs to assess fire damage during overhaul.
