What is a potential hazard associated with high-rise structures for firefighting personnel?

Low visibility due to smoke is indeed a significant hazard for firefighting personnel in high-rise structures. When a fire breaks out, smoke can rapidly fill the corridors, stairwells, and areas of the building, reducing visibility to near zero. This poses a serious challenge for firefighters who must navigate through these conditions to locate and extinguish the fire, as well as to perform rescues.

The lack of visibility can lead to disorientation, making it difficult to find exits or assess the situation, which not only jeopardizes the safety of firefighters but also complicates rescue operations for any occupants trapped within the building. Successful firefighting and evacuation efforts in high rises often hinge on the ability to see clearly and move safely through smoke-filled environments.
