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 Prote
ction 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 techn
ical 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. -

(2) The acoustical performance of the public address system is superior to the performance capabilities of listed fire alarm notification equipment as applied to large volume spaces.
(3) The public address system is designed, installed, and maintained to have the tremendous power to be heard over crowd noises and performances.
(4) The large assembly areas are characterized by the lack of fire separation.
(5) The public address system announcement, live or pre-defined, can adequately perform the inten
ded function of notifying occupants of an emergency condition and of what actions to take.
(6) The public address system with its required emergency power back-up has the reliability to provide effective occupant notification in these venues that are, in most cases, highly managed and supervised.
(7) Costs associated with providing an NFPA 72 notification system are not justified in that such a system would be redundant to the public address system that is equivalent, if not superior, from a technical and reliability standpoint.

NFPA5000®
远方有你Building Construction and Safety Code®
2006Edition
This edition of NFPA5000®,Building Construction and Safety Code®,was prepared by the Committees on the Building Code and acted on by NFPA at its June Association Technical Meeting held June6–10,2005,in Las Vegas,NV.It was issued by the Standards Council on July29,2005,with an effective date of August18,2005,and
supersedes all previous editions.
This edition of NFPA5000was approved as an American National Standard on August18,
2005.
Origin and Development of NFPA5000
The inaugural edition of NFPA5000®,Building Construction and Safety Code®,was issued in
2002and 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 than100years of experience in developing volun-
tary consensus-based codes and standards related to the built environment.From the Life
Safety Code®to the National Electrical Code®,sprinkler installation,fuel gas,and myriad other
occupancy-specific and installation standards,NFPA codes 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 NFPA adheres to.NFPA5000has 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.NFPA5000applies 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 NFPA101®,Life Safety Code®,as they relate to new construction were a
fundamental starting point for the content as well as the format and arrangement of
NFPA5000for the first edition.Consistent with NFPA’s performance-based code initiative,
NFPA5000establishes a clear set of goals and objectives for specifying the expected outcome
for occupant safety and building performance 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 exercise the performance-based design approach.In addition,they can be used as a
tool for evaluating 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),and the Access Board,among others.The all-hazard design provisions for NFPA5000
are rounded out with the use of criteria that include elements for a range of design loads and
natural hazards.
This edition of NFPA5000has revised several sections based on recent events,changes to
federal regulations,and incorporation of new technologies among others.The2006edition
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.Several
changes have been incorporated to address certain means of egress design features,including
an increase in stair width when large populations would be expected to utilize the stairs and a
mandate for stairway descent devices in certain multistory buildings.Chapter12was com-
pletely revised to be consistent with the recent changes to the Americans with Disabilities Act
Accessibility Guidelines(ADAAG)and the technical provisions of ICC/ANSI A117.1,Ameri-
can National Standard for Accessible and Usable Buildings and Facilities.Building rehabilitation
