Building and fire codes require the construction of some interior walls and floor-ceiling assemblies to resist the passage of fire for a certain length of time, usually expressed in hours. These rated assemblies usually separate rooms, apartments, means of egress including exit corridors and stairways , and the different levels floors of the building. The method of preventing the passage of fire and products of combustion around and through pipes, electrical conduits, ducts, and cables is usually determined in new construction and remodeling by the architect and fire protection engineer, based on building, fire, and NFPA Life Safety Code requirements. During repairs and building and systems maintenance, the Authorities Having Jurisdiction AHJ expect that the same level of protection will be maintained as in the original construction. In most types of construction and occupancies, these penetrations of non-rated partitions and floor-ceiling assemblies require no special procedures; although some occupancies and AHJ will require smoke seal or fire caulk around each pipe, conduit, duct, and cable on both sides of the penetration. The methods and materials used to seal around these penetrations may vary between listings in the Certifications Directory.
