When equipped with the Validator option, Ruskin ﬁre/smoke dampers eq are smart enough to test themselves! T The Ruskin Validator automates and simpliﬁes code required ﬁre/smoke damper testing for s signiﬁcant cost savings over the life of the building. More importantly, the Ruskin Validator h helps ensure that your HVAC life-safety systems will function properly when needed. And now, the Ruskin Validator comes mounted on the ﬁre/smoke damper to further An simp simp installation. simplify “This standard shall prescribe minimum requirements for safety to life and property from fire. These requirements shall be intended to accomplish the following: • Restrict the spread of smoke through air duct systems within a building or into a building from the outside. • Restrict the spread of fire through air duct systems from the area of fire origin, whether located within the building or outside. • Maintain the fire-resistive integrity of building components and elements such as floors, partitions, roofs, walls, and floor- or roof-ceiling assemblies affected by the installation of air duct systems. • Minimize the ignition sources and combustibility of the elements of the air duct systems. • Permit the air duct systems in a building to be used for the additional purpose of emergency smoke control.6 It is also important to understand the damper terms as published in NFPA 90A: w w w. esmag a zin e. c o m ESM11084Ruskin.indd 1 43 10/15/08 3:51:00 PM Input 60 at www.esmagazine.com/instantproductinfo Smart 3900 Dr. Greaves Rd., Kansas City, MO 64030 (816) 761-7476 Fax (816) 765-8955 www.ruskin.com R Air & Sound Control Validator SPEAKING IN CODE Every building owner and person responsible for design, specification, installation and inspection, testing, and maintenance must be thoroughly familiar with the applicable codes and standards that apply to a particular building and occupancy. While this article is not all inclusive of the provisions relative to dampers, it is important to understand the purpose of NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems, 2002 edition: Building owners, managers, and industry professionals must be familiar with the codes and standards legally adopted in the jurisdiction. As an example, some of the requirements of NFPA 101®, Life Safety Code®, 2006 edition mandate that, “Air-conditioning, heating, ventilating ductwork, and related equipment, including smoke dampers and combination fire and smoke dampers, shall be installed in accordance with NFPA 90A, Standard for the Installation of AirConditioning and Ventilating Systems.”8 NFPA 90A also provides for exceptions to installation requirements for dampers. An example is described in section 5.3.5.1.5., “Smoke dampers shall not be required in health care occupancies where exempted by NFPA 101, Life Safety Code.”9 This exception for health care occupancies include dampers in duct penetrations of smoke barriers in fully ducted HVAC systems where an approved, supervised automatic sprinkler system has been provided for smoke compartments adjacent to the smoke barrier. The 2006 edition of the International Building Code® mandates that fire dampers shall comply with the requirements of UL 555 Standard for Fire Dampers. Smoke dampers shall comply with the requirements of UL 555S Standard for Smoke Dampers. Combination fire/smoke dampers shall comply with the requirements of both UL 555 and UL 555S.10 For a better understanding of dampers relative to Underwriters Laboratories obtain a copy of UL Marking Guide for Dampers for Fire Barrier and Smoke Applications and Ceiling Dampers Marking and Application Guide.11 As mentioned earlier, building owners, managers, and industry professionals should apply the maintenance provisions of NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems, 2002 edition.

While the value was based on practices of that time, it creates a much larger difference from the 1997 value of a statistical life than would be inferred from inflation alone.4 An article in Variety, the weekly entertainment business magazine, reported that total funds awarded to victims (e.g., injured survivors and families of fatal victims) of the 1980 MGM Grand Hotel fire had reached $113 million and were expected to reach $152 to $160 million once all claims were settled.5 While contributing factors related to dampers at the MGM Grand were not solely responsible for the loss of life and injuries, the NFPA confirms that building owners, managers, and industry professionals must take proactive measures to ensure compliance to minimize the risks and liability. • Fire damper. A device, installed in an air distribution system, designed to close automatically upon detection of heat, to interrupt migratory airflow, and to restrict the passage of flame. • Smoke damper. A device within the air distribution system to control the movement of smoke. • Combination fire and smoke damper. A device that meets both the fire damper and smoke damper requirements.”7 YEARS of EXCELLENCE R http://www.ruskin.com http://www.esmagazine.com/instantproductinfo http://www.ruskin.com http://www.esmagazine.com
