In a partial evacuation scenario for a high-rise, how far must occupants be evacuated from the building?

In a partial evacuation scenario for a high-rise, requiring occupants to be evacuated at least the height of the building ensures that they are moved to a safe distance, considering smoke, heat, and potential structural hazards. This safety distance is crucial because during a fire, especially in taller structures, smoke can rise and spread horizontally, impacting areas beyond the immediate vicinity of the fire. By evacuating to a distance equal to the building's height, occupants can be better protected from these dangers.

This standard reflects the understanding of how far smoke and other hazardous conditions can travel, ensuring occupants are in a significantly safer zone until the situation is under control. Evacuating to a distance that corresponds directly to the height of the structure is a precautionary measure that aligns with best practices in emergency management and fire safety protocols.
