Tentative Interim Amendment NFPA 5000 Building Construction and Safety Code 2006 Edition Reference A.16.3.4.3.4 TIA 06-1 NFPA 5000 SC 06-7-27/Log No. 844 Pursuant to Section 5 of the NFPA Regulations Governing Committee Projects, the National Fire Protection Association has issued the following Tentative Interim Amendment to NFPA 5000 Building Construction and Safety Code, 2006 edition. The TIA was processed by the Building Code Committee and was issued by the Standards Council on July 28, 2006, with an effective date of August 19, 2006. A Tentative Interim Amendment is tentative because it has not been processed through the entire standards-making procedures. It is interim because it is effective only between editions of the standard. A TIA automatically becomes a proposal of the proponent for the next edition of the standard; as such, it then is subject to all of the procedures of the standards-making process. Add an asterisk to 16.3.4.3.4 and add new annex text to chapter 16 for assembly occupancies as follows A.16.3.4.3.4 Automatic occupant notification in assembly occupancies with occupant load sufficient to require a fire alarm system is problematic. The physical configuration including large-volume spaces of assembly venues and the human behavior characteristics of the occupants including elevated levels of occupant-generated noise present challenges to effective occupant notification by a voice communication system in compliance with NFPA 72, National Fire Alarm Code. The technical committee responsible for the assembly occupancy chapters of this Code seriously deliberated the subject of mandating occupant notification strictly in accordance with NFPA 72 during recent revision cycles, in particular during the processing of the 2006 edition when public proposals and comments were received on the subject. The deliberations resulted in the committee action of retaining the requirements in place which permit the occupant notification voice announcement to be made per 16.3.4.3.4 via an approved voice communication or public address system, provided with emergency power, that is audible above the ambient noise level of the assembly occupancy. The technical committee acted to maintain the occupant notification provisions that have been in the Code for numerous editions for the following reasons 1 The effective day-to-day operation of assembly occupancy venues is highly reliant on the functionality of the public address system, thus ensuring reliability comparable to that found in a typical NFPA 72 notification system.

It was issued by the Standards Council on July 29, 2005, with an effective date of August 18, 2005, and supersedes all previous editions. This edition of NFPA 5000 was approved as an American National Standard on August 18, 2005. Origin and Development of NFPA 5000 The inaugural edition of NFPA 5000, Building Construction and Safety Code, was issued in 2002 and was the first model building code developed using the full open consensus–based procedures accredited by the American National Standards Institute. The first edition marked the culmination of NFPA’s more than 100 years of experience in developing volun- tary consensus-based codes and standards related to the built environment. From the Life Safety Codeto the National Electrical Code, sprinkler installation, fuel gas, and myriad other occupancy-specific and installation standards, NFPAcodes and standards, as well as the codes and standards of other consensus-based standards development organizations, have ad- dressed almost every aspect of the built environment. The significant gap in the code regime for the built environment, however, had been the lack of an open consensus–based model building code. NFPA’s Building Code endeavors to be responsive to the needs of the enforcement, user, and design communities and to be consistent with the other principles of code development that NFPAadheres to. NFPA5000 has also established a set of goals and objectives that work to deliver a safe, usable, and functional building at the end of the design process. In addition to fire, a design hazard that has always been, and will always be, a major component of any building code, NFPA’s other codes and standards address many of the subject areas and hazards that comprise a building code. NFPA5000 applies NFPA’s collection of consensus codes and standards and adds requirements for other design provisions. Related natural hazards and building interior environmental issues that must be addressed are also included in the code. The provisions of NFPA 101, Life Safety Code, as they relate to new construction were a fundamental starting point for the content as well as the at and arrangement of NFPA 5000 for the first edition. Consistent with NFPA’s perance-based code initiative, NFPA5000 establishes a clear set of goals and objectives for specifying the expected outcome for occupant safety and building perance based upon the Code requirements. These goals and objectives also extend to the expected outcome for a building, its contents, and its mission, when applicable. These goals and objectives are critical in allowing those affected by codes to rcise the perance-based design approach. In addition, they can be used as a tool for uating equivalency provisions on project-specific jobs or designs. When appropriate, additional criteria were derived from numerous sources, including the American Society of Civil Engineers ASCE, the Federal Emergency Management Agency FEMA,andtheAccessBoard,amongothers.Theall-hazarddesignprovisionsforNFPA5000 are rounded out with the use of criteria that include elements for a range of design loads and natural hazards. This edition of NFPA 5000 has revised several sections based on recent events, changes to federal regulations, and incorporation of new technologies among others. The 2006 edition has introduced an optional design approach for selection of allowable building and heights and areas that is based on construction type and enhanced fire compartments.
