jen is a fire protection engineer in the building and life safety department where she serves as staff liaison to multiple nfpa technical committees, including smoke management systems responsible for the development of nfpa 92. special thanks to jen for her contribution! section 11.8 of the code addresses smoke control systems. nfpa 92 applies to the design, installation, acceptance testing, operation, and ongoing periodic testing of smoke control systems. it incorporates methods for applying engineering calculations and reference models to provide a designer with the tools to develop smoke control system designs.
the smoke control system’s performance objectives and acceptance criteria should be approved by the ahj prior to its installation. in addition to the initial inspection and testing, smoke control systems are required to be operationally tested on an approved schedule, per nfpa 1, section 188.8.131.52; which nfpa 92, section 8.6 clarifies is annually for dedicated systems, and semi-annually for non-dedicated systems. examples of these systems include atrium and mall smoke control systems. each of these components is required to be inspected, tested, and maintained as part of the smoke control system. it is the responsibility of the owner/occupant to retain records pertaining to inspection, testing, and maintenance of the systems per nfpa 1, section 10.2.5. smoke control systems are a significant part of life safety, and therefore any time that a system is impaired for more than four hours, the authority having jurisdiction is required to be notified.
this standard protects life and reduces property loss by establishing requirements for the design, installation, and testing of smoke control systems used a smoke control system is a system that controls the movement of smoke and air in a building. it can be made up of multiple different components standard for smoke-control systems utilizing barriers and pressure differences. nfpa 92a was withdrawn in annual 2011 and incorporated into nfpa 92., people also search for, people also search for, nfpa 92a, smoke control system design pdf, smoke control system calculations.
nfpa 92 covers all types of systems used to address the impact of smoke from fire, with mandatory provisions for the design, installation, and testing of both new and retrofitted smoke control systems in buildingsu2014including openings and leakage through egress doors in stairways. smoke control systems fall into one or two categories, as outlined in nfpa 92, section 4.2: smoke containment systems or smoke management nfpa 92 breaks down the types of smoke control systems into two major categories: smoke containment and smoke management. a smoke-containment nfpa 92: standard for smoke control systems is the gold standard for the design of smoke control systems in the united states. referenced by, types of smoke control systems, nfpa 92 b, smoke control panel, passive smoke control system, smoke control testing requirements, smoke control system testing, smoke control system requirements, nfpa 92 2021.
