International Building Code

2006 Building Code

Whenever a fire barrier is violated, law requires that it be restored to its original rating.
When various trades break through fire barriers to run cables and pipes, they must be held accountable

Section 109.3.6

Protection of joints and penetrations in fire resistant rated assemblies shall not be concealed from view until inspected and approved.

712.3.1.2 Through-penetration firestop system.

Through penetrations shall be protected by an approved penetration firestop system installed as tested in accordance with ASTM E 814 or UL 1479, with a minimum positive pressure differential of 0.01 inch (2.49 Pa) of water and shall have an F rating of not less than the required fire-resistance rating of the wall penetrated

712.4 Horizontal assemblies.

Penetrations of a floor, floor/ceiling assembly or the ceiling membrane of a roof/ceiling assembly

712.4.1.2 Through-penetration firestop system.

Through penetrations shall be protected by an approved through-penetration firestop system installed and tested in accordance with ASTME 814 or UL1479, with a minimum positive pressure differential of 0.01 inch (2.49 Pa) of water. The system shall have an F rating and a T rating of not less than 1 hour but not less than the required rating of the floor penetrated.

SECTION 713 FIRE-RESISTANT JOINT SYSTEMS

713.1 General.

Joints installed in or between fire-resistance rated walls, floor or floor/ceiling assemblies and roofs or roof/ceiling assemblies shall be protected by an approved fire-resistant joint system designed to resist the passage of fire for a time period not less than the required fire-resistance rating of the wall, floor or roof in or between which it is installed.

Fire-resistant joint systems shall be tested in accordance with Section 713.3.

The void created at the intersection of a floor/ceiling assembly and an exterior curtain wall assembly shall be
protected in accordance with Section 713.4.

713.3 Fire test criteria.

Fire-resistant joint systems shall be tested in accordance with the requirements of either ASTM E1966 or UL 2079. Nonsymmetrical wall joint systems shall be tested with both faces exposed to the furnace, and the assigned fire-resistance rating shall be the shortest duration obtained from the two tests. When evidence is furnished to show that the wall was tested with the least fire-resistant side exposed to the furnace, subject to acceptance of the building official, the wall need not be subjected to tests from the opposite side.

713.4 Exterior curtain wall/floor intersection.

Where fire resistance-rated floor or floor/ceiling assemblies are required, voids created at the intersection of the exterior curtain wall assemblies and such floor assemblies shall be sealed with an approved material or system to prevent the interior spread of fire. Such material or systems shall be securely installed and capable of preventing the passage of flame and hot gases sufficient to ignite cotton waste where subjected to ASTM E 119 time-temperature fire conditions under a minimum positive pressure differential of 0.01 inch (0.254 mm) of water column (2.5 Pa) for the time period at least equal to the fire-resistance rating of the floor assembly. Height and fire-resistance requirements for curtain wall spandrels shall comply with Section 704.9.

703.6 Marking and identification.

Fire walls, fire barriers, fire partitions, smoke barriers and smoke partitions or
any other wall required to have protected openings or penetrations shall be effectively and permanently
identified
with signs or stenciling
. Such identification shall:

1. Be located in accessible concealed floor, floor-ceiling or attic spaces;
2. Be repeated at intervals not exceeding 30 feet (914 mm) measured horizontally along the wall or partition; and
3. Include lettering not less than 0.5 inch (12.7 mm) in height, incorporating the suggested wording: “FIRE AND/OR SMOKE BARRIER—PROTECT ALL OPENINGS,” or other wording.

Exception: Walls in Group R-2 occupancies that do not have a removable decorative ceiling allowing access to the concealed space.

ASTM E 2174 & ASTM E 2393 were proposed by FCIA to the Fire Safety Committee, as special inspections, in Chapter 17 of the building code, at the Baltimore ICC Code Hearings. The ICC Fire Safety Committee Approved the proposal.

If there is no public comment to challenge the decision, it becomes part of the consent agenda, to be approved by the assembly at the ICC Final Action Hearings in May, 2010.
