13.12 Atriums/Malls. Atriums and medical malls shall meet the requirements of
NFPA 101 (reference 13a) and shall be designed to comply with NFPA 92B
Protection From Hazards. Protection from hazards shall be in
accordance with MIL-HDBK-1008. Storage rooms shall be considered hazardous
areas and comply with appropriate occupancy chapter requirements of NFPA 101.
Flammable and Combustible Liquid Storage. Flammable and
combustible liquid storage must be in a fire resistance rated enclosure
complying with NFPA 30.
Gas Storage. Flammable gas storage must be in a fire
resistance rated enclosure complying with NFPA 99. Nonflammable medical gas
storage must be in a fire resistance rated enclosure complying with NFPA 99.
Oxygen Storage. Oxygen storage rooms must be located at least 50
feet from flammable storage rooms.
Integrated Building Systems (IBS). For a functional description
of the various elements of the Integrated Building System refer to Section 19.
Requirements. Fire safety requirements for facilities designed
using the Integrated Building System (IBS) shall be in accordance with the
same codes and standards applicable to any non-IBS facility. The following
IBS criteria is based upon a special study titled Fire Performance of
Interstitial Space Construction System (NBSIR 85-3158) (reference 13m),
conducted by the National Institute of Standards and Technology (NIST). The
IBS criteria herein is coordinated with the requirements of the referenced
codes and standards to accommodate the nontraditional characteristics of the
IBS approach. Where variations between this standard and other applicable
codes and standards occur, the fire safety design requirements for IBS
facilities indicated herein, shall govern.
Basic Concept. In IBS designs, as in traditional building
configurations, smoke compartments are separated by fire-rated smoke barriers.
The area of an IBS module, i.e. smoke compartment, can be no greater than
22,500 sq. ft. The IBS modular zones which require smoke barrier separation
Neither, the distribution zone, nor the utility pod is required to be
subdivided by smoke barriers. In addition to this section, refer to Section
19, Integrated Building System, for a description of the IBS configurations,
modules and zones.
NOTE 1: The integration of IBS facility building modules with NFPA smoke
of this non-traditional building concept. When applying NFPA 101, the modular
configuration of the IBS is a significant benefit because compartmentation
becomes a natural byproduct.
NOTE 2: Coordination of Systems. Supply services to any system module shall
serve an area that corresponds to the smoke compartment, including electrical
power, fire alarm zoning, automatic sprinkler zoning, and HVAC zoning. Supply
services are defined as utilities, i.e., water supply, electrical power and
medical gases that originate outside of the module, feeding utilities which
are centrally located in the utility pod of each system module and then
distributed to each functional zone via the distribution zone of each system
