The fatalities, injuries and damage associated with fire can increase dramatically if smoke and flame are allowed to spread uncontrolled by way of a building's ventilation system. As a result, the fire protection community and many others have invested considerable energy and resources to restrict the spread of fire and smoke through air duct systems. Fire dampers are used to protect openings in heating, ventilating and air conditioning (HVAC) duct system passing through fire resistive walls, partitions or floors. Leakage rated dampers (or smoke dampers) are used to restrict or control the movement of smoke through opening in smoke barriers (either vertical or horizontal) or in engineered smoke control systems. In cooperation with the damper, HVAC and other related industries, Underwriters Laboratories Inc. (UL) certifies a variety of products and equipment for use in HVAC duct systems. This article describes the tests that fire and leakage rated dampers must pass to be certified.
