At least one exit door shall be available from every attached seat or standee space in an assembly space, or from the most remote point in the space when movable seats are provided or, when no seats are provided, within the primary travel distance limitation listed in Table 1029.7. In addition, an alternate exit door shall be available from every attached seat or standee space, or from the most remote point when attached seats are not provided within the secondary travel distance limitation listed in Table 1029.7. Such alternate exit door may serve to satisfy the requirements for primary travel distance for other seats or locations. Exit door satisfying the primary and secondary travel distance requirements for any one seat or location shall be separated in accordance with Section 1007.1. Where aisles are provided for seating, the distance shall be measured along the aisles and aisle accessway without travel over or on the seats.\n\nExceptions: For the purposes of this section, travel distances may be measured in accordance with the following exceptions:\n\n1. \n\t\t\t\t\t\t\t\t\t\t\t\t\tSmoke-protected assembly seating: The primary travel distance shall be permitted to be measured from each seat or standee space to the nearest entrance to a vomitory or concourse, and shall not exceed 200 feet (60 960 mm). The secondary travel distance shall be permitted to be measured from each such seat or standee space to an alternate entrance to the vomitory or concourse, and shall not exceed 300 feet (91 440 mm). The travel distance from any such entrances to the vomitory or concourse to a stairway, ramp or walk on the exterior of the building shall not exceed 200 feet (60 960 mm).\n\n2. \n\t\t\t\t\t\t\t\t\t\t\t\t\tOpen-air seating served by exit access stairways and ramps: The primary travel distance shall be permitted to be measured from each seat or standee space to the closest riser of an exit access stairway or the closest slope of an exit access ramp that are outside the assembly space. The secondary travel distance shall be permitted to be measured to the closest riser of an alternate exit access stairway or the closest slope of an alternate exit access ramp that are outside the assembly space.\n\n3. \n\t\t\t\t\t\t\t\t\t\t\t\t\tAssembly with safe areas: Where an assembly space is provided with an exit access doorway that opens directly to a safe area in accordance with Section 1029.19, the primary travel distance shall be permitted to be measured to such an exit access doorway. The secondary travel distances shall also be permitted to be measured to an alternate exit access doorway that opens directly to a safe area. The travel distance within safe areas shall be in accordance with Section 1017 based on the occupancy classification of the main occupancy of the building or portion thereof to which the assembly space is ancillary. Where a safe area contains other occupancies, travel distances within such safe area shall comply with Section 1017.\n\n4. \n\t\t\t\t\t\t\t\t\t\t\t\t\tAssembly with open exterior spaces: Where an

Exterior exit passageways, ramps, or steps leading from open exterior spaces shall be not less in width than required for the occupant load of all exits discharging into the open exterior space. The width of such exit passageways shall be based on the capacities listed in Section 1005.1, but in no case less than 10 feet (3048 mm).\n\n5. \n\t\t\t\t\t\t\t\t\t\t\t\t\tOpen exterior spaces.
