**CHAPTER 14** **FIRESTOP PROTECTION** **1401.0 General.** **1401.1 Applicability.** Piping penetrations of required fire resistance-rated walls, partitions, floors, floor/ceiling assemblies, roof/ceiling assemblies, or shaft enclosures shall be protected in accordance with the requirements of the building code, and this chapter. **1402.0 Construction Documents.** **1402.1 Penetrations.** Construction documents shall indicate with sufficient detail how penetrations of fire-resistance rated assemblies shall be fire stopped prior to obtaining design approval. **1403.0 Installation.** **1403.1 Materials.** Firestop systems shall be installed in accordance with this chapter, the building code, and the manufacturer\'s installation instructions. **1404.0 Combustible Piping Installations.** **1404.1 General Requirements.** Combustible piping installations shall be protected in accordance with the appropriate fire resistance rating requirements in the building code that list the acceptable area, height, and type of construction for use in specific occupancies to assure compliance and integrity of the fire resistance rating prescribed. **1404.2 Fire-Resistance Rating.** Where penetrating a fire resistance-rated wall, partition, floor, floor-ceiling assembly, roof-ceiling assembly, or shaft enclosure, the fire-resistance rating of the assembly shall be restored to its original rating. **1404.3 Firestop Systems.** Penetrations shall be protected by an approved penetration firestop system installed as tested in accordance with ASTM E119, ASTM E814, UL 263, or UL 1479 with a positive pressure differential of not less than 0.01 of an inch of water (0.002 kPa). Systems shall have an F rating of not less than 1 hour but not less than the required fire resistance rating of the assembly being penetrated. Systems protecting floor penetrations shall have a T rating of not less than 1 hour but not less than the required fire-resistance rating of the floor being penetrated. Floor penetrations contained within the cavity of a wall at the location of the floor penetration do not require a T rating. No T rating shall be required for floor penetrations by piping that is not in direct contact with combustible material. **1404.4 Connections.** Where piping penetrates a rated assembly, the combustible piping shall not connect to noncombustible piping unless it is capable of being demonstrated that the transition is in accordance with Section 1404.3. **1404.5 Insulation and Coverings.** Insulation and coverings on or in the penetrating item shall not be permitted unless the specific insulating or covering material has been tested as part of the penetrating firestop system. **1404.6 Sleeves.** Where sleeves are used, the sleeves shall be securely fastened to the fire-resistance-rated assembly. The (inside) annular space between the sleeve and the penetrating item and the (outside) annular space between the sleeve and the fire-resistance-rated assembly shall be fire stopped in accordance with this chapter. **1405.0 Noncombustible Piping Installations.** **1405.1 General Requirements.** Noncombustible piping installations shall be protected in accordance with the appropriate fire resistance rating requirements in the building code that list the acceptable area, height, and type of construction for use in specific occupancies to ensure compliance and integrity of the fire-resistance rating prescribed. **1405.2 Fire-Resistance Rating.** Where penetrating a fire resistance-rated wall, partition, floor, floor-ceiling assembly, roof-ceiling assembly, or shaft enclosure, the fire-resistance rating of the assembly shall be restored to its original rating. **Exceptions:** \(1) Concrete, mortar, or grout shall be permitted to be used to fill the annular spaces around cast-iron, copper, copper alloy, or steel piping that penetrates concrete or masonry fire-resistant-rated assemblies. The nominal diameter of the penetrating item shall not exceed 6 inches (150 mm), and the opening size shall not exceed 144 square inches (0.093 m2). The thickness of concrete, mortar, or grout shall be the full thickness of the assembly or the thickness necessary to provide a fire-resistance rating not less than the required fire-resistance rating of the assembly penetrated. \(2) The material used to fill the annular space shall prevent the passage of flame and hot gases capable of igniting cotton waste for the time period equivalent to the fire resistance rating of the assembly, where tested to standard(s) referenced in Section 1405.3. **1405.3 Firestop Systems.** Penetrations shall be protected by an approved penetration firestop system installed as tested in accordance with ASTM E119, ASTM E814, UL 263, or UL 1479 with a positive pressure differential of not less than 0.01 of an inch of water (0.002 kPa). Systems shall have an F rating of not less than 1 hour but not less than the required fire-resistance rating of the assembly being penetrated. Systems protecting floor penetrations shall have a T rating of not less than 1 hour but not less than the required fire-resistance rating of the floor being penetrated. Floor penetrations contained within the cavity of a wall at the location of the floor penetration do not require a T rating. No T rating shall be required for floor penetrations by piping that is not in direct contact with combustible material. **1405.4 Connections.** Where piping penetrates a rated assembly, the combustible piping shall not connect to noncombustible piping unless it is capable of being demonstrated **1405.5 Unshielded Couplings.** Unshielded couplings shall not be used to connect noncombustible piping unless it is capable of being demonstrated that the fire-resistive integrity of the penetration is maintained. **1405.6 Sleeves.** Where sleeves are used, the sleeves shall be securely fastened to the fire-resistance-rated assembly. The (inside) annular space between the sleeve and the penetrating item and the (outside) annular space between the sleeve and the fire-resistance-rated assembly shall be fire stopped in accordance with this chapter. **1405.7 Insulation and Coverings.** Insulation and coverings on or in the penetrating item shall not be permitted unless the specific insulating or covering material has been tested as part of the penetrating firestop system. **1406.0 Required Inspection.** **1406.1 General.** Prior to being concealed, piping penetrations shall be inspected by the Building Official to verify compliance with the fire-resistance rating prescribed in the building code. **1406.2 Examination.** The Building Official shall conduct a thorough examination of sufficient representative installations, including destructive inspection, to provide verification of satisfactory compliance with this chapter, the appropriate manufacturer\'s installation instructions applied by the installer, construction documents, specifications, and applicable manufacturer\'s product information. **1406.3 Penetrations.** The Building Official shall determine the type, size, and quantity of penetrations to be inspected. **1406.4 Field Installations.** The Building Official shall compare the field installations with the documentation supplied by the installer to determine the following: \(1) The required F ratings (1 hour, 2 hour, 3 hour, or 4 hour) and T ratings (0 hour, 1 hour, 2 hour, 3 hour, or 4 hour) of the penetration firestop systems are at least the same as the hourly rating of the assembly being penetrated. \(2) The penetrating firestop system includes the penetrating item as documented through testing of the systems conducted by an independent testing agency. \(3) The penetrating firestop system is installed as tested.
