What is one common hazard firefighters face during structure fires?

During structure fires, one significant hazard that firefighters face is the possibility of structural collapse. This risk arises due to the intense heat generated by the fire, which can weaken the integrity of building materials, such as wood and steel. Firefighters must be aware that as they combat the flames inside a structure, the stability of the walls, roof, and floors can be compromised, leading to dangerous situations where parts of the structure may suddenly give way.

While exposure to smoke is certainly a concern, it's only one aspect of the broader environmental hazards present at a fire scene. Heat exhaustion from weather conditions is also a factor, but it doesn't specifically arise from the structural elements involved in firefighting operations. Likewise, a lack of available water supply can create challenges but is not a direct hazard of the structure itself during a fire. In contrast, structural collapse can occur unexpectedly and poses a direct and immediate threat to firefighters' safety, making it a critical hazard to consider.
