What are the requirements for exit access travel distance in areas open to an atrium according to the 2018 International Building Code?

The exit access travel distance in areas open to an atrium must comply with Section 1017. At the level of exit discharge, the travel distance is determined by Section 1017. For paths not at the level of exit discharge, the portion within the atrium cannot exceed 200 feet.

The 2018 International Building Code specifies that exit access travel distance for areas open to an atrium must adhere to certain requirements. If the egress path does not pass through the atrium, the travel distance must comply with Section 1017. When the egress path is through the atrium at the level of exit discharge, the travel distance is also determined by Section 1017. However, if the path is not at the level of exit discharge, the part of the travel distance within the atrium cannot exceed 200 feet.
