What is the maximum distance within an atrium for egress travel if it does not occur at the level of exit discharge?

In a commercial building, the maximum distance for egress travel within an atrium, when not occurring at the level of exit discharge, is set to ensure that occupants can safely and quickly access an exit in case of an emergency. The International Building Code (IBC) typically specifies that the maximum travel distance for egress should not exceed 200 feet for areas that are not considered to be at the level of exit discharge.

This limit is important because it accounts for the potential complexities of navigating through an atrium, including the vertical component of travel and potential obstacles that may hinder rapid evacuation. Thus, maintaining a maximum distance of 200 feet allows for a balance between safety, accessibility, and practicality in design.

While the other options reflect longer distances, they do not align with recognized safety standards for egress in atrium spaces specifically. Therefore, adhering to the 200 feet limit helps to ensure that buildings provide a safe environment and comply with code requirements, which is crucial for the protection of occupants in emergency situations.
