502.7.2 Prescriptive methods.

Penetrations of floor/ceiling and wall assemblies required to have a fire-resistance rating by steel, ferrous or copper conduits, pipes, tubes, or vents no greater than 6 inches (152 mm) in diameter with a total cross-sectional area of opening of 144 square inches (92 903 mm

2

) or less shall be permitted to be sealed by 1 of the following methods without certification by a manufacturer of those performing the installation:

1.

Concrete or masonry walls or floors. The annular space around penetrations in a single concrete or masonry wall/floor by steel, ferrous or copper conduits, pipes, tubes or vents shall be sealed with concrete, grout or mortar installed through the full thickness of the floor or the thickness required to maintain the fire-resistance rating.

2.

For walls and floors in prior code buildings. In prior code buildings, the annular space around penetrations through walls and floors shall be permitted to be of materials and thickness matching the adjacent existing construction in a manner in which they can be shaped, tightly fitted, and permanently secured in position, provided, however, that any firestopping sealant used in conjunction with such penetrations shall be noncombustible.

The system shall have an F rating of 2 hours minimum for walls/horizontal penetrations. For horizontal penetration, the system shall have a T rating of 2 hours minimum where penetration is not contained and located inside rated wall cavities. The required ratings for both F and T rating shall not be less than the required rating of the floor/horizontal assemblies penetrated. Such installers shall be certified by the manufacturer of the firestopping assembly for the specific assembly.

502.7.3.1 Manufacturer certification.

The licensee responsible for the penetration shall obtain certification for the installation of the approved through-penetration fire stop system from the manufacturer of such fire stop system and provide proof of the certification in a form and manner acceptable to the department.
