These rules are included as an aid to the user in identifying changes from the previous edition. A reference in brackets [ ] following a section or paragraph indicates material that has been extracted from another NFPA document. As an aid to the user, the complete title and edition of the source documents for extracts in mandatory sections of the document are given in Chapter 2 and those for extracts in informational sections are given in Annex C.
Requests for interpretations or revisions of extracted text shall be sent to the technical committee responsible for the source document. Information on referenced publications can be found in Chapter 2 and Annex C. Chapter 1 Administration 1. This standard shall cover construction, installation, operation, and maintenance of systems for air conditioning and ventilating, including filters, ducts, and related equipment, to protect life and property from fire, smoke, and gases resulting from fire or from conditions having manifestations similar to fire.
This standard shall prescribe minimum requirements for safety to life and property from fire. These requirements shall be intended to accomplish the following: 1 Restrict the spread of smoke through air duct systems within a building or into a building from the outside 2 Restrict the spread of fire through air duct systems from the area of fire origin, whether located within the building or outside 3 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 4 Minimize the ignition sources and combustibility of the elements of the air duct systems 5 Permit the air duct systems in a building to be used for the additional purpose of emergency smoke control 1.
The provisions of this standard shall not be intended to be applied retroactively. Where a system is being altered, extended, or renovated, the requirements of this standard shall apply only to the work being undertaken. Nothing in this standard shall be intended to prevent the use of new methods or devices, provided that sufficient technical data are submitted to the authority having jurisdiction to demonstrate that the proposed method or device is equivalent in quality, strength, durability, and safety to that prescribed by this standard.

A device used to reduce or remove airborne solids from heating, ventilating, and air-conditioning systems by electrostatic means. A continuous passageway for the transmission of air that, in addition to air ducts, can include air connectors, air duct fittings, dampers, plenums, fans, and accessory air-handling equipment but that does not include conditioned spaces.
A conduit or passageway for conveying air to or from heating, cooling, air conditioning, or ventilating equipment, but not including the plenum. A material such as an adhesive, insulation, banding, a coating s , film, or a jacket used to cover the outside surface of an air duct, fan casing, or duct plenum. A material such as an adhesive, insulation, a coating s , or film used to line the inside surface of an air duct, fan casing, or duct plenum.
A device used to reduce or remove airborne solids from heating, ventilating, and air conditioning. Any opening through which air is removed from a space and returned to an air distribution system. Any opening through which air is delivered to a space from an air distribution system. An appliance receiving, conditioning, and delivering air supplied through an air distribution system.
An opening designed to allow the movement of environmental air between two contiguous spaces. A device installed to limit radiant heat transfer through an air outlet or air inlet opening in the ceiling of a floor- or roof-ceiling assembly having not less than a 1-hour fire resistance rating. Such a device is described in the construction details for some tested floor- or roof-ceiling assemblies. A device that meets both the fire damper and smoke damper requirements. 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.
A device within an air-distribution system to control the movement of smoke. Air that is supplied, returned, recirculated, or exhausted from spaces for the purpose of modifying the existing atmosphere within the building. The time, in minutes or hours, that materials or assemblies have withstood a fire exposure as established in accordance with the test procedures of NFPA , Standard Methods of Tests of Fire Resistance of Building Construction and Materials.
A wall separating buildings or subdividing a building to prevent the spread of fire and having a fire resistance rating and structural stability. A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors when subjected to fire or heat. A compartment or chamber to which one or more air ducts are connected and that forms part of the air distribution system.
An individual room containing an air-handling unit s used to gather air from various sources and combine the air within the room for returning to the air-handling unit. The space between the top of the finished ceiling and the underside of the floor or roof above where used to supply air to the occupied area, or to return or exhaust air from the occupied area.
The space between the top of the finished floor and the underside of a raised floor where used to supply air to the occupied area, or to return or exhaust air from the occupied area. The airborne solid and liquid particulates and gases evolved when a material undergoes pyrolysis or combustion, together with the quantity of air that is entrained or otherwise mixed into the mass.
