1114B.2 Egress and Areas for Evacuation Assistance 1114B.2.1 [For SFM] General. In buildings or portions of buildings required to be accessible, accessible means of egress shall be provided in the same number as required for exits by Chapter 10. When an exit required by Chapter 10 is not accessible, an area for evacuation assistance shall be provided. Areas for evacuation assistance shall comply with the requirements of this code and shall adjoin an accessible route of travel complying with this code. EXCEPTIONS: 1. Areas of evacuation assistance are not required in buildings or facilities having a supervised automatic sprinkler system. 2. In alterations of existing buildings, areas of evacuation assistance are not required. 1114B.2.2 [For SFM] Areas for evacuation assistance. 1114B.2.2.1 [For SFM] Location and construction. An area for evacuation assistance shall be one of the following: 1. [For SFM] A portion of a stairway landing within a smokeproof enclosure, complying with Section 1005.3.3. 2. [For SFM] A portion of an exterior exit balcony located immediately adjacent to an exit stairway when the exterior exit balcony complies with Section 1006.3. Openings to the exterior of the building located within 20 feet (6096 mm) of the area for evacuation assistance shall be protected with fire assemblies having a three-fourths-hour fire-protection rating. 3. [For SFM] A portion of a one-hour fire-resistive corridor complying with Section 1004.3.4 located immediately adjacent to an exit enclosure. 4. [For SFM] A vestibule located immediately adjacent to an exit enclosure and constructed to the same fire-resistive standards as required by Section 1004.3.4. 5. [For SFM] A portion of a stairway landing within an exit enclosure which is vented to the exterior and is separated from the interior of the building by not less than one-hour fire-resistive door assemblies. 6. [For SFM] When approved by the building official, an area or room which is separated from other portions of the building by a smoke barrier. Smoke barriers shall have a fire-resistive rating of not less than one hour and shall completely enclose the area or room. Doors in the smoke barrier shall be tightfitting smoke- and draft-control assemblies having a fire-protection rating of not less than 20 minutes and shall be self-closing or automatic closing. The area or room shall be provided with an exit directly to an exit enclosure. When the room or area exits into an exit enclosure which is required to be of more than one-hour fire-resistive construction, the room or area shall have the same fire-resistive construction, including the same opening protection, as required for the adjacent exit enclosure. 7. [For SFM] An elevator lobby complying with Section 1114B.2.3. 1114B.2.2.2 [For SFM] Size. Each area for evacuation assistance shall provide at least two accessible areas that are not less than 30 inches by 48 inches (762 mm by 1219 mm).

The total number of such 30-inch by 48-inch (762 mm by 1219 mm) areas per story shall not be less than one for every 200 persons of calculated occupant load served by the area for evacuation assistance. EXCEPTION: The building official may reduce the minimum number of 30-inch by 48-inch (762 mm by 1219 mm) areas to one for each area for evacuation assistance on floors where the occupant load is less than 200. 1114B.2.2.3 [For SFM] Adjacent stairway width. Each stairway adjacent to an area for evacuation assistance shall have a minimum clear width of 48 inches (1219 mm) between handrails. 1114B.2.2.4 [For SFM] Two-way communication. 1114B.2.2.4.1 [For SFM] A telephone with controlled access to a public telephone system or another method of two-way communication shall be provided between each area of refuge and the primary entry.

Elevator shafts and adjacent lobbies are pressurized as required for smoke-proof enclosures in Section 1005.3.3. Such pressurization system shall be activated by smoke detectors on each floor located in a manner approved by the building official. Pressurization equipment and its ductwork within the building shall be separated from other portions of the building by a minimum two- hour fire-resistive construction. 1114B.2.4 [For SFM] Alarms/emergency warning systems/accessibility.
