What potential hazard is indicated by the discovery of pitched or sagging doors during overhaul?

The discovery of pitched or sagging doors during the overhaul phase indicates a potential hazard of structural collapse. When doors are not hanging straight, it can suggest that the structural integrity of the building has been compromised, often due to fire damage impacting support elements like beams and frames. This compromise can lead to hazards such as the risk of the roof or walls failing, posing a significant danger to firefighters and personnel during operations.

Firefighters must be vigilant in assessing the stability of structures, particularly after a fire, as weakened conditions can lead to sudden and unexpected collapses. Recognizing signs like sagging doors helps crews to take appropriate precautions or make tactical decisions to ensure safety while conducting their duties in the fire scene.
