Notice to Distribution:
NFPA 10 2007 Edition Notable Changes from the 2002 Edition
by Craig Voelkert
The entire document has been changed in accordance with a new
NFPA mandated
Manual of Style. As a result, Chapters have been renumbered and
paragraphs have
been moved from one Chapter to another as deemed appropriate
under the mandatedManual of Style. A direct comparison of a
numbered paragraph in the 2002 Edition
with the same numbered paragraph in the 2007 Edition will in
most cases be impossible.
No paragraph is allowed to have more than one sentence so many
paragraphs containing
multiple sentences in the 2002 Edition of NFPA 10 now have the
exact same wording but
are split into multiple paragraphs.
Any wording that was not considered enforceable has been either
changed to
enforceable language or has been moved to the Annex which is
meant for informationalpurposes only.
No exceptions are allowed and as such some of the paragraphs had
to be changed,
renumbered or expanded in order to comply with this mandate.
In the past, any new Edition of an NFPA Standard would have a
solid bar next to a
paragraph that was changed or if the paragraph was a new
requirement, making it easy tospot the differences between the
previous Standard and the new Edition. Since the entire
Standard has been changed, there are no solid bars indicating
new material in the 2007
Edition of NFPA 10.
AN IMPORTANT REMINDER:NFPA Standards such as NFPA 10,are just
that Standards, not enforceable Code. They must be adopted into the
applicable
Code, usually referencing the specific Edition, before they are
considered enforceable.
Be certain to check with your local or State authority regarding
which Edition of the
NFPA 10 Standard, if any, is referenced in the current fire code
before presenting any of
these changes as being required to meet code.

While the 2007 Edition will require careful reading and time to
gain a workingknowledge of the new sections and Chapters, there are
many positive changes that will
improve fire protection and the role of portable extinguishers.
The following list is by no
means all inclusive of the changes and those involved with the
selection, purchase, sale,inspection, maintenance and installation
of portable extinguishers should read the 2007
Edition of NFPA 10 very carefully.
Amerex Corporation cannot represent the NFPA 10 Committee, speak
for the Committee,give Formal Interpretations on the Standard or
represent the Committee in any way. Any
views or opinions expressed in some of our explanations are
strictly those of Amerex
Corporation
Chapter 3 Definitions:. A definition for Certified Person has
been added and is an
extremely important item later in the Standard. Definitions for
Maintenance,Inspection, Hanger, Cabinet and Bracket are now found
as ExtinguisherMaintenance, Extinguisher Inspection, etc. Other
definitions have also been moved
within this chapter as sub headings under broader definitions.
The definition forAutomatic Residential Fire Extinguisher Unit has
been dropped.
Chapter 4 General Requirements (New Chapter): Paragraph 4.4
(formerly
paragraph 1.5.4) Obsolete Extinguishers has added 5 new
categories of obsolete
extinguishers:
(9) Pressurized water fire extinguishers manufactured prior to
1971This will coincide with material specifications that became
mandated at the time.
(10) Any extinguisher that needs to be inverted to operateWhile
Soda-Acid/ Two Part Chemical Foam and Cartridge Operated Water
extinguishers
have been obsolete for some time, there were other types of
extinguishers that required
being inverted to operate. This addition will remove them from
service so that all
extinguishers in service will be operated upright.(11) Any
stored pressure extinguisher manufactured prior to 1955This will
take many extinguishers using the old UL rating System out of
service to avoidconfusion regarding the applicable ratings.
(12) Any extinguisher with 4B, 6B, 8B, 12B, and 16B fire
ratingsThis will have a similar effect as above.
(13) Stored pressure water extinguishers with fiberglass shells
(pre-1976).
Two new important paragraphs have also been added in this
Chapter:
4.4.1 Dry Chemical stored pressure extinguishers manufactured
prior to October1984 shall be removed from service at the next 6
year maintenance interval or the next
hydrotest interval, whichever comes first.This requirement
coincides with the date of changes to UL 299. For more information
onthe importance of UL 299 go to the FEMA (Fire Equipment
Manufacturers Association)
website www.femalifesafety.org . Once in the site, click on
educational materials then
scroll to portables and click on UL 299 brochure or guide. This
information may be
downloaded, printed or obtained from Amerex or the FEMA
offices.

4.4.2 Any extinguisher that can no longer be serviced in
accordance with themanufacturers maintenance manual is considered
obsolete and shall be removed from
service.If the extinguishing agent or parts either manufacturers
recommended replacementparts or parts specifically listed for use
in the fire extinguisher - are not available, then the
extinguisher cannot be serviced according to the manufacturers
manual.
A new requirement that was formerly only found buried in the
Scope and thereforeoften considered unenforceable has been added:
5.4.2 Selection by Occupancy. Fire
Extinguishers shall be provided for the protection of both the
building structure and
the occupancy hazards contained therein regardless of the
presence of any fixed firesuppression systems.Cooking areas have
been removed from the Extra High Hazard category and are
treated
as a separate special hazard as in the 2002 Edition of the
Standard.
Under Class B Fires, new wording has been added for Pressurized
Flammable
Liquids and Pressurized Gas Fires. 5.5.1.1.2 Large capacity dry
chemicalextinguishers of 10 lb. (4.54 kg) or greater and a
discharge rate of 1 lb. /sec.
(0.45/kg/sec) or more shall be used to protect these hazards.
This same requirement islisted for Three-Dimensional
Fires.Previously the only guidance was to consult the manufacturer
of this specialtyequipment, this wording gives much better
guidance. Several manufacturers, including
Amerex make fast flow or high flow extinguishers which are
needed for these and
other hazards.
A new section 5.5.4 Obstacle Fires - has been added requiring
the same flow rates
and capacity as above along with the options of multiple
extinguishers to be usedsimultaneously or foam extinguishers.
A new section 5.5.7 Areas Containing Oxidizers has been added
requiring only
water type extinguishers be used and specifically barring the
use of ABC dry chemicalin these hazards.This new requirement adds
greater safety. Many manufacturers, including Amerex, havepublished
warnings and Tech tips on this subject. This will help to guide
local
authorities towards proper selection of extinguishers under
these circumstances.
Chapter 6: Installation (formerly Chapter 5: Distribution of
Fire Extinguishers):
6.6.3 All solid fuel cooking appliances (whether or not under a
hood) with fire boxes
of 5 ft3 (0.14m3) volume or less shall at least have a listed
2-A water-type fireextinguisher or 1.6 gal (6 L) wet chemical
extinguisher listed for Class K fires.This brings NFPA 10 in
agreement with NFPA 96 for this particular hazard.
Chapter 7 Inspection, Maintenance, and Recharging of Portable
Extinguishers
(formerly Chapter 6):
Personnel performing service of portable extinguishers must now
be certified. Thedefinition for certified person in Chapter 3 is: A
person that has been certified by a
recognized organization through a formal certification program
or by an equipment
-
8/7/2019 NFPA2007Amx
5/8
manufacturer that has a certification program, that is
acceptable to the authorityhaving jurisdiction.
7.1.2.3 The certification of service personnel shall be required
after February 16,2008.
There are now 6 steps in the inspection procedures instead of 9.
The requirement for
checking the safety seals and tamper indicators; checking to see
if the HMIS label is inplace; examination for obvious physical
damage, corrosion, leakage or clogged nozzle
are all no longer included in the inspection procedures
(although these most of these
items remain in the procedures if certain circumstances are
present). Thoserequirements have been moved to the procedures for
annual maintenance. Also,
hefting or weighing extinguishers to determine fullness during
the inspection is
confined to only self expelling, cartridge operated
extinguishers and pump tanks.
An entire section on electronic monitoring, where it can
specifically be used and
requirements for its use has been added including 5
paragraphs.
Other paragraphs have been added specifying when electronic
monitoring may not beused in lieu of a physical inspection.
A new table has been added showing the frequency of internal
examination intervals,
including an annual internal examination and a paragraph has
been added that
requires ab annual internal examination for some extinguishers
that are exposed totemperatures in excess of their listing.
Annex Material: As in previous standards, the items in the
Standard marked with an
asterisk (*) will have supplementary material in the Annex. The
Annex is still for
informational purposes only and is not considered to be part of
the Standard
therefore the Annex material is not enforceable. Here are some
of the more significantchanges to the Annex:
The references and specifications for using dry ice converters
for recharging CO2
extinguishers have been removed. In another section it states
Dry ice converters
should not be used to recharge carbon dioxide extinguishers.
There is a new reference to Certified Persons which includes a
generic example of a
certification program.
Again, these are by no means all of the changes in the 2007
Edition of NFPA 10. We
strongly suggest that you obtain a copy of the Standard and read
it carefully and
thoroughly. Even if your current fire code is using a previous
Edition of the Standard,you will be prepared for the many changes
coming your way should the 2007 Edition
become adopted as part of your code.
