In a highrise fire situation, which individuals are typically the most endangered?

In a high-rise fire situation, individuals who are immediately above the fire floor are typically the most endangered. This is because heat, smoke, and toxic gases tend to rise, accumulating on the floors directly above the fire. These individuals often face the greatest risk as they are in close proximity to the source of heat and harmful gases but may have limited escape options due to the effects of the fire spreading.

People on the upper floors, while in danger, may have more time to evacuate as fires can take time to reach those levels. Individuals on the roof might be at risk depending on the fire's spread, but their elevated position can sometimes provide a safer vantage point. Those evacuating from the lobby, while also at risk during a chaotic exit, are generally not as immediately endangered compared to those directly above the fire floor where conditions can rapidly deteriorate.
