Current Vision of NFPA
Consensus Codes™ Set
• Energy Efficiency—ASHRAE 90.1 and
90.2
• Manufactured Housing—NFPA 501; HUD
Partnership
• Residential—Keep in NFPA 5000
– Extract document in future
NFPA Building Code
Committees
• Technical Correlating Committee
• 13 Committees with dual roles – LSC and
Building Code
• 3 New Technical Committees:
– Structures and Construction
– Building Materials
– Building Systems
Scope
TC on Fire Protection Features
• Responsible for documents on
construction compartmentation, including
the performance of:
– assemblies,
– openings, and
– penetrations
• as related to the protection of life and
property from fire and other circumstances.
Model Codes Form the Basis for
Local Regulations &

the Market For Building
Products

The Future is NOW!!!
Code Issues To Be Discussed
• Smoke leakage
• Quality assurance
• Perimeter fire barrier systems
Smoke Leakage
• Smoke Barriers – Subdivision of building
space intended to provide a temporary area
of refuge for building occupants
• Smoke Partition – Partition intended to
provide a minimal amount of time for
people to pass by an area
• Both use terms such as “limit”, “restrict”, or
“resist” smoke leakage
IBC
• Smoke Barrier – Penetrations shall comply
with Section 711 (general section on
penetrations)
• Smoke Partition (new to 2002 Supplement)
– Annular space shall be filled with an
approved material to resist the passage of
flame and products of combustion
IBC – 2002 Changes
• FS33-02 submitted by Hilti, Inc.
– Required penetrations of smoke partitions to be
protected with materials or systems that can
withstand 400oF and capable of withstanding
anticipated movement of the penetrating item
– Disapproved
IBC – 2002 Changes
• FS38-02 submitted by 3M Company
– Required penetrations of corridor walls and
smoke barriers to meet a leakage rate of 25 cfm
per sq ft as determined by UL 1479.
– Disapproved
– Public Comment submitted by the IFC but the
item was still disapproved.
NFPA 5000
• Where the penetrating item uses a sleeve to
penetrate the smoke barrier, …the space
between the item and the sleeve shall be be
filled with a material capable of resisting
the transfer of smoke, in accordance with
the air leakage requirements of section 6 of
UL 1479.
NFPA 5000
• All proposed changes attempting to
introduce an air leakage requirement failed
the written ballot of the Technical
Committee
Quality Assurance
• How to ensure that the selection and
installation of penetration firestopping has
been properly executed.
IBC – 2002 Changes
• FS110-02 submitted by the FCIA
– Installations shall be subjected to special
inspections conducted in accordance with
ASTM E2174
• Exception: Where the code official performs the
inspection
– Disapproved
NFPA 5000
• A quality assurance program shall be
prepared and monitored by the registered
design professional for firestop systems and
devices and systems installed to protect
joints.
• Text is in NFPA 5000
Any Questions?
IBC - 2000
• 712.2 Exterior curtain wall/floor
construction
– 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.
IBC - 2000
• 712.2 Exterior curtain wall/floor construction
– Such material shall be securely installed and capable of
preventing the passage of flame and hot gases sufficient
to ignite cotton waste where subjected to ASTME E119
time-temperature fire conditions under a minimum
positive pressure differential of 0.01 inch of water
column for the time period at least equal to the fireresistance rating of the floor assembly
2002 Changes to the IBC
• FS39-02 submitted by FCIA
– 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
system to prevent the interior spread of fire. Such
system…..
– Approved as Modified
• Similar change submitted to NFPA 5000 was
accepted by the Committee but failed ballot
2002 Changes to the IBC
• FS40-02 submitted by GICC
– Add a new sentence to read as follows
– Height and fire-resistance requirements for curtain wall
spandrels shall comply with Section 704.9.
– Approved although Public Comment by Thermafiber
requested disapproval
– Nothing in this change eliminates perimeter fire
barrier systems in sprinklered buildings!
• Similar change submitted to NFPA 5000 was
accepted
2002 Changes to the IBC
• FS41-02 submitted by Metal Construction
Association
– ..for the time period equal to the fire-resistance rating of
the exterior curtain wall assembly, or 30 minutes,
whichever is greater.
• Exception: Where the floor is less than the wall, the floor fire
resistance shall be the criteria
– Disapproved
• Similar change submitted to NFPA 5000 was
accepted by the Committee but failed ballot
NFPA 5000
• Where fire resistance-rated floor or floorceiling assemblies are required, voids
created at the intersection of the exterior
curtain wall assemblies and such floor
assemblies shall be sealed with approved
materials.
NFPA 5000
• Such materials shall be capable of
preventing the passage of flame and hot
gases sufficient to ignite cotton waste where
subjected to NFPA 251 time-temperature
fire conditions under a minimum positive
pressure differential of .01 in. of water
column for the time period at least equal to
the fire resistance rating of the floor
assembly.
NFPA 5000
• Annex note indicated that the intent is to
prevent the interior spread of fire through
the void space and not the exterior spread of
fire.
Issues To Be Addressed
• Clarify that the reduction in the spandrel
wall requirements for sprinklered buildings
does NOT eliminate requirement for
perimeter fire barrier systems
– Propose language to 704 to require compliance
with 712 in a paragraph separate from the
sprinkler exception for spandrel wall
protection.
Issues To Be Addressed
• Spandrel wall requirements
– Currently in exterior wall section
– Listing of perimeter fire barrier system could
influence height of spandrel wall
• Reason for GICC proposed language
– Are the existing requirements adequate?
– Is this an issue for the FCIA?
Spandrel Wall Issues
• Increase in height
– Opponents include BOMA, architects, curtain wall
industry, exterior wall panel and glazing industry
– Previous attempts in past 15 years have all failed
– Where is the loss experience, especially in sprinklered
buildings?
• IBC requires sprinkler protection in buildings of 55 ft.
– What about other non-rated exterior wall systems?
Spandrel Wall Issues
• Risk to FCIA
– If the perception is that the increased spandrel
wall is required due to perimeter fire barrier
system, requirements could be changed to
determine perimeter fire barrier performance
based on exterior wall requirements
