What is a common hazard associated with roof operations?

Structural collapse or falling debris is a significant hazard associated with roof operations during firefighting. When firefighters are on the roof, they must be aware that the structure may already be compromised due to the fire, which can weaken support systems. This means the roof might not be able to bear the weight of personnel and equipment, leading to potential collapses. Additionally, during an active fire, roofs can have falling debris, such as burning materials or structural components, which pose a risk to anyone operating above. Understanding this danger is crucial for the safety of firefighters as they perform ventilation or other tasks on rooftops.
