  • 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

 

It applies to all systems for the movement of environmental air in structures that serve the following:

  • Spaces over 708 m3 (25,000 ft3) in volume

  • Buildings and spaces not covered by other applicable NFPA standards
  • Occupants or processes not covered by other applicable NFPA standards
