K. ADD SECTION 920 POST-FIRE SMOKE PURGE SYSTEMS
920.1 Scope and purpose. The purpose of this section is to establish minimum requirements for the design and installation of post-fire smoke purge systems, which are intended for the timely restoration of operations and overhaul activities once a fire is extinguished. Post-fire smoke purge systems are not intended or designed as life safety systems and are not required to meet the provisions of Section 909. Post-fire smoke purge systems shall be required in:
1. High-rise buildings subject to Section 403.
2. Unlimited area buildings subject to Section 507.
3. Buildings with any story exceeding 50,000 square feet (4645 m2) in floor area.
4. Building with spaces exceeding 100 feet (30 480 mm) from natural ventilation openings. Natural ventilation openings shall consist of operable windows and doors of at least 5 percent of the floor area or roof vents per Section 910.
5. High-piled stock or rack storage in accordance with the International Fire Code.
Exceptions: A post-fire smoke purge system is not required in R-2 occupancies where either of the following conditions exists:
1. Openable windows. A post-fire smoke purge system is not required where every habitable room located in dwelling units is provided with windows complying with Chapter 12 and all of the following:
1.1. Minimum window area. Each required window shall provide at least 12 square feet (1.1 m2) of glazed area. The total area of all such windows shall not be less than 10 percent of the floor area of the room or space served.
1.2. Minimum openable area. Each required window shall provide a minimum of 6 square feet (0.56 m2) of openable area. The total area of all such openings shall not be less than 5 percent of the floor area of the room or space served. In addition, each required openable area shall be:
1.2.1. Located wholly at least 30 inches (762 mm) above the finished floor; and
1.2.2. Fully openable to the minimum 6 square feet (0.56 m2), at all times and without limiting stops or devices. Such openings may be achieved through the use of double-hung, sliding, or similar types of windows. However, in the event of the use of casement, hopper, pivot, or awning-type windows, such windows shall satisfy the requirements of this section only when they open to at least 75 degrees.
2. Smoke-proof enclosures. A post-fire smoke purge system is not required where all exits are constructed as smoke-proof enclosures in accordance with Section 1019.1.8.
920.2 Post-fire smoke purge systems in occupancy groups other than R-2.
920.2.1 General design requirements. Post-fire smoke purge systems are permitted to use dedicated equipment, the normal building HVAC system or other openings and shall have the capability to exhaust smoke from occupied spaces. Smoke removal may be by either mechanical or natural ventilation but shall be capable of removing cold smoke. Smoke removed from a space must be discharged to a safe location outside the building and shall not be recirculated into the building in accordance with the Mechanical Code.
920.2.2 Exhaust capability. The system shall have an air supply and smoke exhaust capability in accordance with Table 920.2.2.1. The system need not exhaust from all areas at the same time, but is permitted to be zoned, based on the largest fire area served. For the purpose of calculating system size, the height of a compartment shall be considered to run from slab to slab and include the volume above suspended ceilings. Provisions shall be made for sufficient make-up air. The provisions may include operable windows, doors, building leakage, or mechanical systems. In buildings having occupied floors located less than 55 feet above the lowest level of Fire Department vehicle access, breakable windows may be utilized.
TABLE 920.2.2.1
CAPACITY REQUIREMENTS FOR POST-FIRE SMOKE PURGE SYSTEM (other than R2)
Building Volume (Cubic Feet) | Number of Air Changes per Hour required capacity |
Less than 600,000 | 6 |
600,000-5,000,000 | 4 |
More than 5,000,000 | 2 |
920.2.3 Operation. The post-fire smoke purge system shall be operated by manual controls that are part of the fire command center, in accordance with Section 911, or fire alarm panel when a fire command center is not required. Such control center or panel shall display a graphic indicating the portions of the building served by each post-fire smoke purge system. When a system is zoned into areas of operation less than the entire building, each zone shall have an individual control. Fire Department manual controls of post-fire smoke purge systems shall not override the manual or automatic operation of the smoke control system. Such Fire Department manual controls shall override the fire shutdown signal from the fire alarm system.
920.3 Post-fire smoke purge systems in occupancy Group R-2. Post-fire smoke purge systems in R-2 occupancies shall comply with either Section 912.3.1 or 912.3.2. Smoke removed must be discharged to a safe location outside the building and shall not be recirculated into the building in accordance with the International Mechanical Code.
920.3.1 Stair ventilation. The top of all enclosed exit stairs shall be provided with a reversible fan system capable of introducing fresh air or exhausting air at a rate of 6 air changes per hour or 1 cubic foot per minute per square foot (cfm/ft2) [0.00508 m3/(s.m2)], whichever is greater, based on the area of the largest floor. Such system shall be operated by manual controls that are part of the fire command center, as per Section 911, or fire alarm panel when a fire command center is not required. Such control center or panel shall display a graphic indicating the portions of the building served by each post-fire smoke purge system. The operation of such system shall be controlled by Fire Department personnel by manually opening stair doors at the appropriate story.
920.3.2 Corridor ventilation. The ducts and fans that provide fresh air supply to the public corridors in accordance with the Mechanical Code shall be provided with reversible fans and duct sizes capable of introducing fresh air to or exhausting air from the corridor at a rate of 6 air changes per hour or 1 cubic foot per minute per square foot (cfm/ft2) [0.00508 m3/(s.m2)], whichever is greater, based on the area of the largest apartment plus the area of the public corridor. Such system shall be operated by manual controls that are part of the fire command center, as per Section 911, or fire alarm panel location when a fire command center is not required. Each floor to be ventilated shall be by individual controls. Such control center or panel shall display a graphic indicating the portions of the building served by each post-fire smoke purge system.
920.4 Maintenance. The building owner shall maintain post-fire smoke exhaust systems in good operational condition. Records of annual testing shall be maintained on the premises for inspection by the department and Fire Department personnel.
