(Note to editor: Remove asterisk from 8.2 and relocate to ) 9

11 5000 FR413 BLD-FIR Final Action: (A ) A The intent of this provision is to permit the provisions of either ASCE/SFPE 29, Standard Calculation Methods for Structural Fire Protection, or ACI 216.1/TMS , Standard Method for Determining Fire Resistance of Concrete and Masonry Code Requirements for Determining Fire Resistance of Concrete and Masonry Construction Assemblies, to be used for the calculation of fire resistance of concrete or masonry elements or assemblies 5000 FR435 BLD-FIR Final Action: (A (New) ) Recommendation: Add new text to read as follows: A Where the construction meets the provisions of (1), (2) or (2), the required exterior wall fire resistance rating is for fire exposure from the inside only. [221, A.6.9.2] 5000 FR407 BLD-FIR Final Action: (A.8.8.2) Recommendation: Add new text to read as follows: A Firestop materials become systems when installed to the listed firestop system design from an accredited testing laboratory. Installation of firestop materials to the listed system should meet all limitations of the system. FM 4991, Standard for the Approval of Firestop Contractors and the UL Qualified Firestop Contractor Program both provide a quantified qualification of the firestop installer who understands the detailed installation requirements. Where the configuration of a penetrating item or group of items is such that a listed system is determined to be nonexistent and reconfiguration of the penetrations or fire resistance rated assembly is determined to be impractical or impossible, alternative methods for maintaining the integrity of the required fire resistance rating of the assembly should be permitted to be established using an engineering analysis based on a comparison of listed systems prepared by a manufacturer s technical representative of the systems specified, by the laboratory that conducted the original test, or by a professional engineer. ASTM E 2174, Standard Practice for On-Site Inspection of Installed Fire Stops, provides guidance for the inspection of through-penetration fire stop systems tested in accordance with ASTM E 814, Standard Test Method for Fire Tests of Through-Penetration Fire Stops, and ANSI/UL 1479, Standard for Fire Tests of Through-Penetration Firestops. 10

12 5000 FR408 BLD-FIR Final Action: (A ) Recommendation: A Materials used to protect joints become systems when installed to the listed joint system design from an accredited testing laboratory. Installation of joint materials to the listed system should meet all limitations of the system. FM 4991, Standard for the Approval of Firestop Contractors and the UL Qualified Firestop Contractor Program both provide a quantified qualification of the joint system installer who understands the detailed installation requirements. Where the configuration of a joint is such that a listed system is determined to be nonexistent and reconfiguration of the joint or fire resistance rated assembly is determined to be impractical or impossible, alternative methods for maintaining the integrity of the required fire resistance rating of the assembly should be permitted to be established using an engineering analysis based on a comparison of listed systems prepared by a manufacturer s technical representative of the systems specified, prepared by the laboratory that conducted the original test, or by a professional engineer. On-site inspection of firestopping is important in maintaining the integrity of any vertical or horizontal fire barrier. Two standard practice documents were developed with the ASTM process to allow inspections of through-penetration firestops, joints, and perimeter fire barrier systems. ASTM E 2393, Standard Practice for On-Site Inspection of Installed Fire Resistive Joint Systems and Perimeter Fire Barriers, provides guidance for the inspection of fire-resistive joints and perimeter fire barrier joint systems tested in accordance with the requirements of ASTM E 1966, Standard Test Method for Fire-Resistive Joint Systems, or with ANSI/UL 2079, Standard for Tests for Fire Resistance of Building Joint Systems. ASTM E 2393 contains a standardized report format, which would lead to greater consistency for inspections 5000 FR419 BLD-FIR Final Action: (A ) Recommendation: A Openings might include items such as stairways, hoistways for elevators, dumbwaiters, and inclined and vertical conveyors; and shaftways used for light, ventilation, or building services. A Openings might include items such as stairways; hoistways for elevators, dumbwaiters, and inclined and vertical conveyors; shaftways used for light, ventilation, or building services; or expansion joints and seismic joints used to allow structural movements FR423 BLD-FIR Final Action: (A ) Recommendation: A Where atriums are used, there is an added degree of safety to occupants because of the large volume of space into which smoke can be dissipated. However, there is a need to ensure that dangerous concentrations of smoke are promptly removed from the atrium, and the exhaust system needs careful design. For information about systems that can be used to provide smoke protection in these spaces, see the following: (1) NFPA 92, Standard for Smoke Control Systems (2) Design of Smoke Management Systems by J.H. Klote and J.A.Milke (2) Principles of Smoke Management 11

13 5000 FR402 BLD-FIR Final Action: (A (3)) Recommendation: Add text to read as follows: A (3) Draftstops defined in the requirements of NFPA 13, Standard for the Installation of Sprinkler Systems, are curtain style descending from the ceiling surface or ceiling plane 5000 FR428 BLD-FIR Final Action: (A (2)) Recommendation: Add new annex language as follows: A (2) See NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems FR406 BLD-FIR Final Action: (A and A ) Recommendation: Add a new section to read: A The total quantities of flammable liquids in any area should comply with the provisions of other recognized codes, including NFPA 1, Fire Code, and NFPA 30, Flammable and Combustible Liquids Code. In addition, special consideration should be given to the following: (1) Obstructions created by the installation of hand-rub solution dispensers (2) Location of dispensers with regard to adjacent combustible materials and potential sources of ignition, especially where dispensers are mounted on walls of combustible construction (3) Requirements for other fire protection features, including complete automatic sprinkler protection, to be installed throughout the compartment (4) Amount and location of the flammable solutions, both in use and in storage, particularly with respect to potential for leakage or failure of the dispenser 5000 FR436 BLD-FIR Final Action: (A ) Recommendation: Add new text to read as follows: A For details, see NFPA 68, Standard on Explosion Protection by Deflagration Venting. 12
