A. Statutory/Legal Authority for This
Rulemaking
This final rule is published under
authority of Federal Hazardous
Materials Transportation Law (Federal
Hazmat Law; 49 U.S.C. 5101 et seq.).
Section 5103(b) of Federal Hazmat Law
authorizes the Secretary of
Transportation to prescribe regulations
for the safe transportation, including
security, of hazardous materials in
intrastate, interstate, and foreign
commerce. This final rule corrects errors
in a final rule published in the Federal
Register on May 3, 2007.
B. Executive Order 12866 and DOT
Regulatory Policies and Procedures
This final rule is not considered a
significant regulatory action under
section 3(f) of Executive Order 12866

Office of Management and Budget. This
rule is not significant under the
Regulatory Policies and Procedures of
the Department of Transportation (44 FR
11034). There are no cost impacts
associated with this final rule.
C. Executive Order 13132
This final rule has been analyzed in
accordance with the principles and
criteria in Executive Order 13132
(‘‘Federalism’’). This final rule does not
adopt any regulation that: (1) Has
substantial direct effects on the States,
the relationship between the national
government and the States, or the
distribution of power and
responsibilities among the various
levels of government; (2) imposes
substantial direct compliance costs on
State and local governments; or (3)
preempts state law. Therefore,
preparation of a federalism assessment
is not warranted.

gases and chemical oxygen generators
(72 FR 4442). Specifically, the January
31 final rule:
(1) Requires cylinders of compressed
oxygen and other oxidizing gases and
packages of chemical oxygen generators
to be placed in an outer packaging that
meets certain flame penetration and
thermal resistance requirements when
transported aboard an aircraft;
(2) Revises the pressure relief device
(PRD) setting limit on cylinders of
compressed oxygen and other oxidizing
gases transported aboard aircraft;
(3) Limits the types of cylinders
authorized for transporting compressed
oxygen aboard aircraft; and
(4) Converts most of the provisions of
an oxygen generator approval into
requirements in the HMR.
II. Appeals
The following organizations
submitted appeals to the January 31
final rule, in accordance with 49 CFR
part 106: Air Canada (AC); Barlen and
Associates, Inc. (Barlen); PSI Plus, Inc.
(PSI); and United Airlines, Inc. (United).
Delta Airlines (Delta) also submitted a
letter expressing its general support for
United’s formal appeal. The appellants
based their appeals on several aspects of
the January 31 final rule, most notably,
the effective date of certain
requirements in the rule, cost and
availability of the required outer
packaging, marking requirements, and
thermal resistance testing. We also
received requests for clarification of
certain requirements of the January 31
final rule. The Good View Trading
Company (GVT) also expressed
concerns about the impact the January
31 final rule will have on the current
exceptions for live fish transported
aboard aircraft.
In this final rule, we are granting the
request to delay the mandatory effective
date from October 1, 2007 until October
1, 2008 to require a new limit on the
pressure relief device (PRD) settings on
cylinders containing compressed
oxygen or other oxidizing gases when
transported aboard aircraft. We are
clarifying the thermal resistance test
methods for packagings for oxygen
cylinders and oxygen generators in
Appendix D to part 178. We are granting
the request to include DOT specification
3E and 39 cylinders among the types of
cylinders authorized for the
transportation of compressed oxygen
and other oxidizing gases aboard
aircraft. In addition, we are providing a
marking option to ensure easier
identification of cylinders equipped
with the new PRD and outer packagings
meeting the flame penetration and
thermal resistance requirements. The
PO 00000
Frm 00082
Fmt 4700
Sfmt 4700
appeals and issues of the appellants and
other concerned parties are discussed in
detail below.
A. Outer Packaging That Meets Certain
Flame Penetration and Thermal
Resistance Requirements When
Transported Aboard Aircraft
The January 31 final rule amended the
HMR to require cylinders of compressed
oxygen and other oxidizing gases and
chemical oxygen generators to be
transported in an outer packaging that:
(1) Meets the same flame penetration
resistance standards as required for
cargo compartment sidewalls and
ceiling panels in transport category
airplanes; and (2) provides certain
thermal protection capabilities so as to
retain its contents during an otherwise
controllable cargo compartment fire.
The outer packaging standard adopted
in the January 31 final rule addresses
two safety concerns: (1) Protecting a
cylinder and an oxygen generator that
could be exposed directly to flames
from a fire; and (2) protecting a cylinder
and an oxygen generator that could be
exposed indirectly to heat from a fire.
These performance requirements must
remain in effect for the entire service
life of the outer packaging.
Under the January 31 final rule, an
outer packaging for a cylinder
containing compressed oxygen or
another oxidizing gas and a package
containing an oxygen generator must
meet the standards in Part III of
Appendix F to 14 CFR part 25, Test
Method to Determine Flame Penetration
Resistance of Cargo Compartment
Liners. An outer packaging’s materials
of construction must prevent
penetration by a flame of 1,700 °F for
five minutes, in accordance with Part III
of Appendix F, paragraphs (a)(3) and
(f)(5) of 14 CFR part 25. A method for
thermal resistance testing of packagings
for oxygen cylinders and oxygen
generators was added by the January 31
final rule under a new Appendix D to
part 178 of the HMR. To ease
understanding of and compliance with
the flame penetration test requirements,
in this final rule we are adding a new
Appendix E to part 178, which will
include the entire test procedure. This
will eliminate the necessity for persons
performing the flame penetration test to
refer to the requirements in Appendix F
to 14 CFR part 25.
In its appeal, United expresses
concern about several aspects of these
provisions, including international
repercussions, risk assessment and
analysis, effects of this rulemaking on
travelers requiring medical oxygen, and
the cost basis for the packaging required
by the January 31 final rule.

rwilkins on PROD1PC63 with RULES
Federal Register / Vol. 72, No. 188 / Friday, September 28, 2007 / Rules and Regulations
Specifically, United contends that no
test data or other substantiation of
compliance with requirements for outer
packaging by any packaging
manufacturer was placed in the public
docket. United also states that although
the January 31 final rule indicates at
least one packaging manufacturer
appears to have addressed the flame
penetration and thermal penetration
standard and is able to produce the
required packaging, neither this
company nor any other has actually
produced it. In addition, United
contends that because the packaging
required by the January 31 final rule
does not yet exist, the cost estimates
made by the agency are unreliable.
We are not persuaded that the
required packagings will be unavailable
or that we have underestimated the cost
of bringing them to market. PHMSA
issued the January 31 final rule only
after reviewing test data and other
materials substantiating the
development of packagings meeting the
performance standard. Based on
consultation with companies that are
able to produce similar packaging and
reviewing their packaging prototypes,
supporting test documentation and cost
estimates, we believe the required
packaging will be available in sufficient
time for the affected parties to comply
with this requirement. (Because of its
confidential proprietary nature, we did
not post this documentation in the
public docket for this rulemaking.)
PHMSA and FAA intend to closely
monitor the availability of the required
packaging as the effective date of this
provision approaches and will consider
an extension of the compliance date for
this requirement if it is determined that
a sufficient supply of the required outer
packaging is not available.
Likewise, the fact that the required
packaging is not yet commercially
available does not make the cost
estimates for this rulemaking
unreasonable. As referenced in the
January 31 final rule, packaging
manufacturers provided estimates of
costs for the existing ATA specification
300 packagings and the new outer
packaging. We utilized these estimates,
in addition to our own research, in the
regulatory evaluation (available for
review in the public docket for this
rulemaking). Although some of the
figures provided by the commenters
were slightly higher than ours, the
differences were not significant.
Accordingly, we believe that our
estimate of a total cost of $10.8 million
($7.6 million discounted to present
value) over 15 years, for the transport of
oxygen cylinders, and $27.0 million
($16.9 million discounted to present
VerDate Aug<31>2005
18:21 Sep 27, 2007
Jkt 211001
value) over 15 years, for the costs
associated with the transport of
chemical oxygen generators, are
reasonable estimates of the costs of this
rulemaking despite the current lack of
an available outer packaging in an aftermarket condition.
United also refers to the statement in
the January 31 final rule that DOT
intends to submit a paper to the
International Civil Aviation
Organization (ICAO) Dangerous Goods
Panel to propose that the ICAO
Technical Instructions be amended
consistent with the requirements of the
packaging required by the January 31
rulemaking. United requests that a copy
of such a U.S. proposal be placed in the
public docket for HM–224B, and that
the views of other air carriers in the
international community be considered.
United states that PHMSA should
collect input from the international
community before concluding
rulemaking action in this docket
because of the international aviation
environment and PHMSA’s expressed
stance on the benefits of global
harmonization. United also
recommends that if the new
requirements are adopted
internationally through ICAO, the
compliance dates for affected carriers
should coincide to avoid unnecessary
compliance complexity in the aviation
industry.
We agree that the international
community should be considered when
initiating any regulatory change that
could potentially affect international
commerce. As indicated in the January
31 final rule, it was PHMSA’s intention
to submit a working paper pertaining to
this rulemaking for discussion at the
meeting of the ICAO Dangerous Goods
Panel (DGP). PHMSA submitted a paper
to the DGP Working Group of the Whole
(held April 30 to May 4, 2007) which
provided information relative to the
amendments to the HMR to enhance the
requirements for the transportation of
compressed oxygen, other oxidizing
gases and chemical oxygen generators
on aircraft. The working paper can be
viewed on the public ICAO Web site at:
https://www.icao.int/anb/FLS/
DangerousGoods/FLSDG.cfm. A copy of
this working paper has also been placed
in the public docket for this rulemaking.
However, we are not prepared to defer
this rulemaking while changes to
international standards are considered.
As we explained in the January 31 final
rule, the risk of an unintentional
actuation of an oxygen generator or a
cylinder containing oxygen or another
oxidizing gas during an aircraft fire is a
serious safety risk that we believe must
be immediately addressed, without
PO 00000
Frm 00083
Fmt 4700
Sfmt 4700
55093
waiting for the outcome of international
deliberations.
United also contends that the final
rule is inconsistent with PHMSA’s
expressed commitment to promote riskbased, data-driven, and cost-effective
standards. United asserts that PHMSA
justified the January 31 rulemaking on
a worst-case scenario that was not
supported by actual data in the record
and that affected parties therefore
should be given time to review and
comment on such data. As explained in
the January 31 final rule, we have
utilized a risk-based approach to the air
transportation of compressed oxygen
cylinders and oxygen generators since
the tragic events of the ValuJet Airlines
crash in 1996. FAA has established
through testing that cylinders of
compressed oxygen release their
contents at temperatures well below
those that aircraft cargo compartment
liners and structures are designed to
withstand. When the surface
temperature of a cylinder of compressed
oxygen reaches approximately 300 °F,
the increase in internal pressure causes
the cylinder’s pressure relief device to
open and release oxygen. The risk that
such a release could vent directly into
a fire significantly increases the risks
posed by aircraft fires. FAA also found
that use of an outer packaging
specifically designed to provide both
thermal protection and flame
penetration may significantly lengthen
the time a cylinder will retain its
contents when exposed to fire or heat.
Therefore, our rationale for this January
31 final rule is a continuation of our
ongoing risk-based approach and is
centered on the conclusions drawn from
the ‘‘Evaluation of Oxygen Cylinder
Overpacks Exposed to Elevated
Temperatures’’ conducted by FAA
(available for review in the public
docket for this rulemaking).
United also contends that PHMSA did
not adequately address the potential of
the new packaging requirements to
restrict air travel by individuals who
need compressed oxygen to travel. It
states that additional packaging cost and
other related costs could dissuade air
carriers from providing this service. The
commenter also states that although
PHMSA requested information on this
scenario in the January 31 final rule, the
impact could not be considered
sufficiently without adequate and
reliable information on the cost of the
required packaging.
PHMSA is acutely aware of the
specific needs of individuals who
require compressed oxygen to travel,
and has maintained ongoing dialogue
with FAA and other agencies in an
attempt to minimize requirements that
E:\FR\FM\28SER1.SGM
28SER1
55094
Federal Register / Vol. 72, No. 188 / Friday, September 28, 2007 / Rules and Regulations
rwilkins on PROD1PC63 with RULES
may restrict their travel. For example,
PHMSA and FAA have partnered with
the Office of the Secretary of
Transportation to develop a rulemaking
that proposes to provide greater
accommodations for persons with
respiratory disabilities, and provide
passengers free in-flight medical oxygen
in accordance with applicable safety
rules. See ‘‘Nondiscrimination on the
Basis of Disability in Air Travel—
Medical Oxygen and Portable
Respiration Assistive Devices,’’ Docket
No. OST–2005–22298, 70 FR 53108
(September 7, 2005), 70 FR 61241
(October 21, 2005).
The January 31 final rule
complements the goal of providing a
safer environment for people with
disabilities by requiring cylinders of
compressed oxygen and other oxidizing
gases and packages of chemical oxygen
generators to be placed in an outer
packaging that meets certain flame
penetration and thermal resistance
requirements when transported aboard
an aircraft. We note that the current
regulations specified in § 175.501 of the
HMR allow for the use of oxygen by
passengers in the aircraft cabin and
provide for the stowage of a combined
total of six cylinders of compressed
oxygen, which, under the conditions
specified in this section, do not require
that they be placed in the new outer
packaging.
For the reasons cited above, the
appeal to the requirement that an outer
packaging for a cylinder containing
compressed oxygen or another oxidizing
gas and a package containing an oxygen
generator must meet the standards
adopted in the January 31 final rule is
denied.
B. Test Method in Appendix D to Part
178 and Test Protocol for Outer
Packaging
The January 31 final rule amended the
HMR by adding a thermal resistance test
for packagings for oxygen cylinders and
oxygen generators in a new appendix
(Appendix D) to part 178. United
recommends that PHMSA clarify the
test method described in Paragraph 4.1
of this appendix, which states, ‘‘It is
recommended that the cylinder be
closed at ambient temperature and
configured as when filled with a valve
and pressure relief device. The oxygen
generator must be filled and may be
tested with or without packaging.’’
United indicates that it understands
from discussions that took place with
PHMSA and its trade association after
publication of the January 31 final rule
that PHMSA did not intend to require
testing of the outer packaging with inner
receptacles containing hazardous
VerDate Aug<31>2005
18:21 Sep 27, 2007
Jkt 211001
materials. If an alternative filling
material was intended, the commenter
requests PHMSA clarify this portion of
the appendix as applicable. United
suggests that ‘‘any alternate material
should exhibit comparable heatabsorbing properties of compressed
oxygen in the cylinder, or oxidizing
solid in the generator.’’ If, however,
oven testing with packagings containing
hazardous materials is required, the
commenter is uncertain there is a testing
facility capable of performing such a
test.
In publishing the January 31 final
rule, it was our intention to permit the
thermal resistance test to be conducted
on an oxygen cylinder that is either
empty or filled with nitrogen. It was
also our intention that an oxygen
generator must be tested completely
filled with its oxidizing agent.
Therefore, in this final rule, we are
granting United’s request to clarify the
test method described in Appendix D to
Part 178. In addition, we are also
providing an alternative to the use of
thermocouples specified in the test
methods of Appendix D to part 178.
United also expresses concern that the
test protocol for outer packaging
required by the January 31 final rule
will change in the near future. For
example, the commenter points out the
footnote in the preamble at page 4444 of
the January 31 final rule:
The FAA is currently evaluating other nonozone-depleting suppression agents that
could eventually be used in cargo
compartments. Some of these agents can
maintain an adequate level of safety in the
compartment, but the mean temperature may
be slightly higher than 400 °F, which is the
level found during typical halon-suppressed
fires. If an alternative agent is used, the oven
soak temperature level may need to be
adjusted accordingly.
United states that the investment by
itself and other air carriers in the newly
required outer packaging is too
substantial for the test performance
temperature to be addressed in such
vague terms. The commenter requests
clarification of this statement and an
assessment of the probability that it will
result in a revision to the performance
standard for outer packaging by, or
relatively soon after, the October 1, 2007
mandatory compliance date.
We understand the commenter’s
concern regarding the footnote on page
4444 of the January 31 final rule which
references FAA’s ongoing evaluation of
other non-ozone-depleting suppression
agents that could eventually be used in
cargo compartments. By including the
footnote, our intention was to provide
additional information about testing
agents currently under consideration
PO 00000
Frm 00084
Fmt 4700
Sfmt 4700
which may affect test performance
temperatures. For clarification, FAA’s
halon replacement program was
designed to develop minimum
performance standards (MPS) for the
various extinguishing systems used
aboard aircraft. These MPS would
establish a baseline test for new agents
to demonstrate that the agent had
comparable fire-fighting effectiveness to
that of Halon 1211 and 1301. FAA has
developed the MPS for hand-held fire
extinguishers, waste bins, and cargo
compartments. In addition, three
halocarbon agents have been approved
for use in hand-held fire extinguishers.
While alternative agents are currently
being evaluated, none have been
approved for use on aircraft. Further,
the FAA informs us that it has no plans
at present to mandate the use of halon
replacements. Therefore, we do not
anticipate that a revision to the test
protocol for outer packaging required by
the January 31 final rule will occur in
the near future.
C. Effective Date for Pressure Relief
Device Settings on Cylinders of
Compressed Oxygen and Other
Oxidizing Gases
The January 31 final rule revised the
HMR to require a new limit on the
pressure relief device (PRD) settings on
cylinders containing compressed
oxygen or other oxidizing gases when
transported aboard aircraft. To ensure
the cylinder contents are not released
into an aircraft cargo compartment in
the event of a fire, we amended the
HMR to limit the PRD to a setting that
will prevent it from releasing at
temperatures the cylinder will
experience while protected by the outer
packaging. We also amended the HMR
to require cylinders containing
oxidizing gases, including oxygen, be
equipped with PRDs that have a set
pressure equal to the cylinder test
pressure with allowable tolerances of
¥10 to plus zero percent. The effective
date of this requirement for cylinders
containing compressed oxygen and
oxidizing gases was established in the
January 31 final rule as the first
requalification test due after October 1,
2007.
United requests that PHMSA delay
the mandatory effective date from
October 1, 2007 until October 1, 2008 in
order to allow it and other air carriers
to come into compliance with this
requirement of the January 31 final rule.
United states that ‘‘after cylinder
manufacturers develop and implement
new designs, conduct any required
testing, complete the detailed approval
process, and [sic] manufacture and
distribute the new PRDs, it then will be

necessary to transport these cylinders as
air cargo to assure global distribution to
all of United’s facilities where
replacements might need to be installed,
and to accommodate breathing-oxygen
needs for impaired passengers as part of
United’s current effort to serve such
customers.’’ In addition, United states
that procedures for oxygen cylinder
maintenance and quality assurance
programs must be revised, prompting
additional training, testing and
certification of both employees and their
supervisors, and that ‘‘in addition to all
the cylinders that may come due for
periodic retest as early as October 1,
2007, it is assumed that any new oxygen
cylinders purchased as replacement
parts will need to be equipped with the
new PRD as of that date.’’ United states
the demand for PRDs will likely peak
around the October 1, 2007 effective
date specified in the January 31 final
rule, and it foresees an inadequate
supply of PRDs. The commenter further
states that it has over 6,500 cylinders
affected by this rule and, after
discussions with the manufacturers of
these cylinders and external repair
facilities, it is concerned that bringing
its cylinders into compliance with this
requirement by the January 31 final rule
effective date will not be achievable.
We accept the likelihood that more
time may be necessary to allow for the
testing, approval, distribution, and
training associated with this
requirement of the January 31 final rule.
Therefore, we are extending the
effective date for this provision from
October 1, 2007 until October 1, 2008.
By this revised date, the HMR requires
a new limit on the PRD settings on
cylinders containing compressed
oxygen or other oxidizing gases when
transported aboard aircraft. The
effective date of this requirement for
cylinders containing compressed
oxygen and oxidizing gases is
established as the first requalification
test due after October 1, 2008.
In the January 31 final rule, we added
a new § 173.168 that would: (1) Specify
the means to be incorporated into an
oxygen generator to prevent inadvertent
actuation; (2) require the oxygen
generator to be capable of withstanding
a 1.8 meter drop with no loss of
contents or actuation; and (3) specify
packaging, shipping paper, and marking
requirements for those oxygen
generators that are installed in a piece
of equipment sealed or otherwise
packaged so it is difficult to determine
if an oxygen generator is present. The
effective date of these new requirements
is October 1, 2007, except for the
packaging requirement in paragraph (d)
of § 173.168, which becomes effective
VerDate Aug<31>2005

on September 30, 2009. We received a
request for clarification regarding these
effective dates. One commenter requests
clarification as to whether the
requirements prior to the January 31
final rule pertaining to chemical oxygen
generators, particularly approvals, were
intended to remain in effect until the
effective date of the January 31 final
rule. For clarification, our intention in
the January 31 final rule was for the
current requirements concerning
chemical oxygen generators, including
approvals, to remain in effect until the
overall effective date of the January 31
final rule. A similar issue was raised by
the same commenter concerning the
additional requirements for shipment of
nonliquefied (permanent) and liquefied
compressed gases in specification
cylinders found in §§ 173.302a and
173.304a, respectively. The commenter
asks whether it was PHMSA’s intention
to continue current outer packaging
requirements for non-liquefied
(permanent) and liquefied compressed
gases in specification cylinders until the
effective dates specified in these revised
sections.
The answer is yes. It was also our
intention in the January 31 final rule
that the current requirements for the
shipment of nonliquefied and liquefied
compressed gases in specification
cylinders remain in effect until the
effective dates specified under these
revised sections. In this final rule, we
are revising the amendments to
§§ 173.302a and 173.304a to clarify
these effective dates and are redesignating them under new paragraph
(f) of § 173.302—‘‘Filling of cylinders
with non-liquefied (permanent)
compressed gases—’’ and new
paragraph (f) of § 173.304—‘‘Filling of
cylinders with liquefied compressed
gases—’’ respectively, to provide a more
logical, user-friendly format. We are also
revising § 173.301 to direct the user to
these new paragraphs.
D. Marking Requirements
United also urges PHMSA to take
further steps to ensure easier
identification of cylinders equipped
with the new PRD and outer packagings
meeting the flame penetration and
thermal resistance requirements. In its
appeal, the commenter requests that
PHMSA require manufacturers to
distinguish between the modified
cylinders, as well as the modified outer
packaging, through the use of a uniform
marking requirement. United asserts
that such a marking requirement would
have the benefit of clarifying DOT’s
jurisdiction over the manufacturers,
specifically with respect to compliance
with testing, hazmat employee training,
PO 00000
Frm 00085
Fmt 4700
Sfmt 4700
55095
and record-keeping provisions. In
addition, United states that a consistent
visible mechanism will allow its
employees and DOT enforcement
officials to determine whether a UN or
ATA Specification 300 outer packaging
meets the new rule versus prior
requirements, and to identify with
reliable ease and certainty which DOT
and UN cylinders are authorized to
transport specific hazardous materials
by air. United stresses the importance of
such a provision because of the common
airline industry practice of conducting
code share operations and participating
in loaned parts programs.
PHMSA acknowledges the
commenters’ concerns that current
labeling and marking requirements may
not fully identify cylinders equipped
with the new PRD and outer packagings
meeting the flame penetration and
thermal resistance requirements of the
January 31 final rule. However, because
we did not propose any additional
marking or labeling requirements in the
NPRM, we cannot formally adopt a
uniform marking or labeling
requirement in this final rule. Any new
marking or labeling requirement must
be proposed in a future rulemaking to
allow for public comment. Instead,
PHMSA and FAA have developed a
voluntary marking that may be affixed
to an outer packaging meeting the flame
penetration and thermal resistance
requirements of the January 31 final rule
to indicate compliance with these
provisions of the regulations. The
marking is as follows:
DOT31FP
We emphasize that this marking is not
a requirement. We will consider
proposing this marking as a uniform
marking requirement in a future
rulemaking, and, if this or some other
marking is adopted, it would be
incorporated into the HMR as an
acceptable indication that the outer
packaging meets the flame penetration
and thermal resistance requirements
and is in compliance with the
requirements of the January 31 final
rule.
E. Authorized Cylinders for Compressed
Oxygen and Other Oxidizing Gases
The January 31 final rule revised the
HMR to limit cylinders authorized for
the transportation of compressed oxygen
and other oxidizing gases aboard aircraft
to DOT specifications 3A, 3AA, 3AL,
and 3HT in order to minimize numerous
PRD setting requirements for oxygen
cylinders aboard aircraft.
Barlen comments that DOT 39 and
DOT 3E cylinders are safer than 3AL
cylinders and questions why these

Federal Register / Vol. 72, No. 188 / Friday, September 28, 2007 / Rules and Regulations
rwilkins on PROD1PC63 with RULES
cylinders were eliminated in the
January 31 final rule. PSI, a
manufacturer of high-pressure steel
DOT 39 and DOT 3E cylinders, requests
reconsideration of the requirement to
limit cylinders authorized for the
transportation of compressed oxygen
aboard aircraft and a delay in
implementation of the requirements of
the January 31 final rule. This
commenter states the majority of the
cylinders it manufactures are sold to
companies producing gas mixtures used
for gas calibration equipment and
medical devices, such as blood gas
analyzers. PSI notes that although DOT
3A and DOT 3AA cylinders are allowed
in the January 31 final rule, these
cylinders are not used for calibration gas
mixtures because of their excessive
weight. The commenter asserts that the
requirements in the January 31 final rule
would effectively ban the use of the
only cylinders it manufactures. PSI adds
that testing has shown steel DOT 39 and
DOT 3E cylinders will survive fires for
longer periods of time and be more
resistant to higher failure temperatures
than aluminum 3AL cylinders, and,
along with Barlen, requests DOT to
consider permitting the use of these
cylinder types in addition to the DOT
3AL cylinders specified in the January
31 final rule. In addition, PSI requests
DOT to allow limited quantities of
oxygen-rich calibration gas mixtures to
be transported on non-passenger aircraft
such as those operated by Federal
Express and UPS. Finally, PSI requests
a delay in the implementation of this
rule to allow for presentation of
additional information.
We agree with the commenters that
including DOT 39 and DOT 3E
cylinders as cylinders authorized for the
transportation of compressed oxygen
and other oxidizing gases aboard aircraft
does not pose an additional safety
hazard and will provide carriers more
flexibility when transporting these
materials aboard aircraft. Therefore, we
are revising the HMR to limit cylinders
authorized for the transportation of
compressed oxygen and other oxidizing
gases aboard aircraft to DOT
specifications 39, 3A, 3AA, 3AL, 3E,
and 3HT, and UN pressure receptacles
ISO 9809–1, ISO 9809–2, ISO 9809–3
and ISO 7866 cylinders, including a
new limit on the PRD settings.
about the impact that the new outer
packaging requirement in the January 31
final rule will have on the current
exceptions for live fish transported
aboard aircraft. In publishing the
January 31 final rule, our intention was
not to eliminate this exception.
Therefore, for clarification, we are
revising this section to specifically
except it from the new outer packaging
requirements.
In addition, on May 3, 2007, PHMSA
published a final rule under Docket No.
PHMSA–2005–23141 (HM–215F) in the
Federal Register (72 FR 25161). The
HM–215F final rule amended the HMR
to revise and consolidate the
requirements applicable to the use of
the International Civil Aviation
Organization’s Technical Instructions
for the Safe Transport of Dangerous
Goods by Air, the International
Maritime Dangerous Goods Code,
Transport Canada’s Transportation of
Dangerous Goods Regulations, and the
International Atomic Energy Agency’s
Safety Standards Series: Regulations for
the Safe Transport of Radioactive
Material. The revisions and reformatting
provide a user-friendly format to
promote understanding of the
conditions and limitations on the use of
international standards and regulations.
In the HM–215F final rule, the ICAO
Technical Instructions (formerly
§ 171.11) were re-designated as new
§ 171.24. As a result of this designation,
the revisions adopted in this section
under the January 31 final rule were
inadvertently omitted. Therefore, we are
republishing new § 171.24 as amended
in the January 31 final rule for
clarification.
F. Miscellaneous Issues
Currently, § 173.302(c) specifies that
an authorized cylinder containing
oxygen continuously fed to tanks
containing live fish may be offered for
transportation and transported. One
commenter, the Good View Trading

authority of Federal hazardous materials
transportation law (Federal hazmat law;
49 U.S.C. 5101 et seq.). Section 5103(b)
of Federal hazmat law authorizes the
Secretary of Transportation to prescribe
regulations for the safe transportation,

in this final rule do not alter the costbenefit analysis and conclusions
contained in the Regulatory Evaluation
prepared for the January 31, 2007 final
rule. The Regulatory Evaluation is
available for review in the public docket
for this rulemaking.
C. Executive Order 13132
This final rule has been analyzed in
accordance with the principles and
criteria contained in Executive Order
13132 (‘‘Federalism’’). This final rule
preempts State, local and Indian tribe
requirements, but does not amend any
regulation that has direct effects on the
States, the relationship between the
national government and the States, or
the distribution of power and
responsibilities among the various
levels of government. Therefore, the
consultation and funding requirements
of Executive Order 13132 do not apply.
The Federal hazardous materials
transportation law, 49 U.S.C. 5101–
5127, contains an express preemption
provision (49 U.S.C. 5125(b)) that
preempts State, local, and Indian tribe
requirements on the following subjects:
(1) The designation, description, and
classification of hazardous material;
(2) The packing, repacking, handling,
labeling, marking, and placarding of
hazardous material;
(3) The preparation, execution, and
use of shipping documents related to
hazardous material and requirements
related to the number, contents, and
placement of those documents;
(4) The written notification,
recording, and reporting of the
unintentional release in transportation
of hazardous material; and
(5) The design, manufacture,
fabrication, marking, maintenance,
recondition, repair, or testing of a
packaging or container represented,
marked, certified, or sold as qualified
for use in transporting hazardous
material.
This final rule addresses items 2 and
5 above and preempts any State, local,
or Indian tribe requirements not meeting
the ‘‘substantially the same’’ standard.
Federal hazardous materials
transportation law provides at
§ 5125(b)(2) that, if DOT issues a
regulation concerning any of the
covered subjects, DOT must determine
and publish in the Federal Register the
effective date of Federal preemption.
The effective date may not be earlier
than the 90th day following the date of
issuance of the final rule and not later
than two years after the date of issuance.
This effective date of preemption is 90
days after the publication of this final
rule in the Federal Register.

D. Executive Order 13175
This final rule has been analyzed in
accordance with the principles and
criteria contained in Executive order
13175 (‘‘Consultation and Coordination
with Indian Tribal Governments’’).
Because this final rule will not have
tribal implications, does not impose
substantial direct compliance costs on
Indian tribal governments, and does not
preempt tribal law, the funding and
consultation requirements of Executive
Order 13175 do not apply, and a tribal
summary impact statement is not
required.

E. Regulatory Flexibility Act, Executive
Order 13272, and DOT Procedures and
Policies
The Regulatory Flexibility Act of 1980
requires an agency to review regulations
to assess their impact on small entities
unless the agency determines that a rule
is not expected to have a significant
impact on a substantial number of small
entities. This final rule will not impose
increased compliance costs on the
regulated industry. The revisions,
clarifications, and corrections we are
making to the January 31, 2007 final
rule will provide regulatory relief to
persons transporting compressed
oxygen, other oxidizing gases and
chemical oxygen generators on aircraft
by: Delaying the mandatory effective
date from October 1, 2007 until October
1, 2008 to require a new limit on the
pressure relief device (PRD) settings on
cylinders containing compressed
oxygen or other oxidizing gases when
transported aboard aircraft; clarifying
the thermal resistance test methods for
packagings for oxygen cylinders and
oxygen generators in Appendix D to Part
178, including DOT specification 3E
and 39 cylinders to the types of
cylinders authorized for the
transportation of compressed oxygen
and other oxidizing gases aboard
aircraft; and providing a marking option
to ensure easier identification of
cylinders equipped with the new PRD
and outer packagings meeting the flame
penetration and thermal resistance
requirements. Thus, DOT has
determined that this final rule will not
have a significant impact on a
substantial number of small entities.
Accordingly, pursuant to the Regulatory
Flexibility Act, 5 U.S.C. 605(b), DOT
certifies that this rule will not have a
significant economic impact on a
substantial number of small entities.
Therefore, I certify that this rule will not
have a significant economic impact on
a substantial number of small entities.

F. Unfunded Mandates Reform Act of
1995
The Unfunded Mandates Reform Act
of 1995 (the Act) is intended, among
other things, to curb the practice of
imposing unfunded Federal mandates
on State, local, and tribal governments.
Title II of the Act requires each Federal
agency to prepare a written statement
assessing the effects of any Federal
mandate in a proposed or final agency
rule that may result in an expenditure
of $100 million or more (adjusted
annually for inflation) in any one year
by State, local, and tribal governments,
in the aggregate, or by the private sector;
such a mandate is deemed to be a
‘‘significant regulatory action.’’ The
FAA currently uses an inflationadjusted value of $128.1 million in lieu
of $100 million.
This final rule does not contain such
a mandate. The requirements of Title II
do not apply.
G. Paperwork Reduction Act
PHMSA currently has approved
information collections under OMB
Control Number 2137–0572, ‘‘Testing
Requirements for Non-Bulk Packaging’’
with an expiration date of March 31,
2010, and OMB Control Number 2137–

Materials’’ with an expiration date of
March 31, 2008. This final rule imposes
no new information collection and
recordkeeping requirements.
H. Regulation Identifier Number (RIN)
A regulation identifier number (RIN)
is assigned to each regulatory action
listed in the Unified Agenda of Federal
Regulations. The Regulatory Information
Service Center publishes the Unified

materials must be tested;
(2) Each test must be conducted on a flat
16 inch x 24 inch test specimen mounted in
the horizontal ceiling position of the test
apparatus to represent the outer packaging
design;
PO 00000
Frm 00089
Fmt 4700
Sfmt 4700
55099
(3) Testing must be conducted on all
design features (latches, seams, hinges, etc.)
affecting the ability of the outer packaging to
safely prevent the passage of fire in the
horizontal ceiling position; and
(4) There must be no flame penetration of
any specimen within 5 minutes after
application of the flame source and the
maximum allowable temperature at a point 4
inches above the test specimen, centered over
the burner cone, must not exceed 205 °C (400
°F).
(b) Summary of Method. This method
provides a laboratory test procedure for
measuring the capability of cargo
compartment lining materials to resist flame
penetration with a 2 gallon per hour (GPH)
#2 Grade kerosene or equivalent burner fire
source. Ceiling and sidewall liner panels may
be tested individually provided a baffle is
used to simulate the missing panel. Any
specimen that passes the test as a ceiling
liner panel may be used as a sidewall liner
panel.
(c) Test Specimens. (1) The specimen to be
tested must measure 16 ±1⁄8 inches (406 ±3
mm) by 24+1⁄8 inches (610 ±3 mm).
(2) The specimens must be conditioned at
70 °F. ±5 °F. (21 °C. ±2 °C.) and 55% ±5%
humidity for at least 24 hours before testing.
(d) Test Apparatus. The arrangement of the
test apparatus must include the components
described in this section. Minor details of the
apparatus may vary, depending on the model
of the burner used.
(1) Specimen Mounting Stand. The
mounting stand for the test specimens
consists of steel angles.
(2) Test Burner. The burner to be used in
tesing must—
(i) Be a modified gun type.
(ii) Use a suitable nozzle and maintain fuel
pressure to yield a 2 GPH fuel flow. For
example: An 80 degree nozzle nominally
rated at 2.25 GPH and operated at 85 pounds
per square inch (PSI) gauge to deliver 2.03
GPH.
(iii) Have a 12 inch (305 mm) burner
extension installed at the end of the draft
tube with an opening 6 inches (152 mm) high
and 11 inches (280 mm) wide.
(iv) Have a burner fuel pressure regulator
that is adjusted to deliver a nominal 2.0 GPH
of #2 Grade kerosene or equivalent.
Burner models which have been used
successfully in testing are the Lenox Model
OB–32, Carlin Model 200 CRD and Park
Model DPL.
(3) Calorimeter. (i) The calorimeter to be
used in testing must be a total heat flux Foil
Type Gardon Gage of an appropriate range
(approximately 0 to 15.0 British thermal unit
(BTU) per ft.2 sec., 0–17.0 watts/cm2). The
calorimeter must be mounted in a 6 inch by
12 inch (152 by 305 mm) by 3⁄4 inch (19 mm)
thick insulating block which is attached to a
steel angle bracket for placement in the test
stand during burner calibration as shown in
Figure 2 of this part of this appendix.
(ii) The insulating block must be monitored
for deterioration and the mounting shimmed
as necessary to ensure that the calorimeter
face is parallel to the exit plane of the test
burner cone.
(4) Thermocouples. The seven
thermocouples to be used for testing must be
E:\FR\FM\28SER1.SGM
28SER1
55100
Federal Register / Vol. 72, No. 188 / Friday, September 28, 2007 / Rules and Regulations
⁄ inch ceramic sheathed, type K, grounded
thermocouples with a nominal 30 American
wire gage (AWG) size conductor. The seven
thermocouples must be attached to a steel
angle bracket to form a thermocouple rake for
placement in the test stand during burner
calibration.
(5) Apparatus Arrangement. The test
burner must be mounted on a suitable stand
to position the exit of the burner cone a
distance of 8 inches from the ceiling liner
panel and 2 inches from the sidewall liner
panel. The burner stand should have the
capability of allowing the burner to be swung
away from the test specimen during warm-up
periods.
(6) Instrumentation. A recording
potentiometer or other suitable instrument
with an appropriate range must be used to
measure and record the outputs of the
calorimeter and the thermocouples.
(7) Timing Device. A stopwatch or other
device must be used to measure the time of
flame application and the time of flame
penetration, if it occurs.
(e) Preparation of Apparatus. Before
calibration, all equipment must be turned on
and allowed to stabilize, and the burner fuel
flow must be adjusted as specified in
paragraph (d)(2).
(f) Calibration. To ensure the proper
thermal output of the burner the following
test must be made:
(1) Remove the burner extension from the
end of the draft tube. Turn on the blower
portion of the burner without turning the fuel
or igniters on. Measure the air velocity using
a hot wire anemometer in the center of the
draft tube across the face of the opening.
Adjust the damper such that the air velocity
is in the range of 1550 to 1800 ft./min. If tabs
are being used at the exit of the draft tube,
they must be removed prior to this
measurement. Reinstall the draft tube
extension cone.
(2) Place the calorimeter on the test stand
as shown in Figure 2 at a distance of 8 inches
(203 mm) from the exit of the burner cone to
simulate the position of the horizontal test
specimen.
(3) Turn on the burner, allow it to run for
2 minutes for warm-up, and adjust the
damper to produce a calorimeter reading of
8.0 ±0.5 BTU per ft.2 sec. (9.1 ±0.6 Watts/
cm2).
(4) Replace the calorimeter with the
thermocouple rake.
(5) Turn on the burner and ensure that
each of the seven thermocouples reads 1700
°F. ±100 °F. (927 °C. ±38 °C.) to ensure steady
state conditions have been achieved. If the
temperature is out of this range, repeat steps
2 through 5 until proper readings are
obtained.
(6) Turn off the burner and remove the
thermocouple rake.
(7) Repeat (1) to ensure that the burner is
in the correct range.
(g) Test Procedure. (1) Mount a
thermocouple of the same type as that used
for calibration at a distance of 4 inches (102
mm) above the horizontal (ceiling) test
specimen. The thermocouple should be
centered over the burner cone.
(2) Mount the test specimen on the test
stand shown in Figure 1 in either the
rwilkins on PROD1PC63 with RULES

horizontal or vertical position. Mount the
insulating material in the other position.
(3) Position the burner so that flames will
not impinge on the specimen, turn the burner
on, and allow it to run for 2 minutes. Rotate
the burner to apply the flame to the specimen
and simultaneously start the timing device.
(4) Expose the test specimen to the flame
for 5 minutes and then turn off the burner.
The test may be terminated earlier if flame
penetration is observed.
(5) When testing ceiling liner panels,
record the peak temperature measured 4
inches above the sample.
(6) Record the time at which flame
penetration occurs if applicable.
(h) Test Report. The test report must
include the following:
(1) A complete description of the materials
tested including type, manufacturer,
thickness, and other appropriate data.
(2) Observations of the behavior of the test
specimens during flame exposure such as
delamination, resin ignition, smoke, etc.,
including the time of such occurrence.
(3) The time at which flame penetration
occurs, if applicable, for each of the three
specimens tested.

I. Supplementary Background
On January 31, 2007, PHMSA, in cooperation with the Federal
Aviation Administration (FAA), issued a final rule under Docket No.
RSPA-04-17664 (HM-224B) enhancing the safety standards for
transportation by air of compressed oxygen, other oxidizing gases and
chemical oxygen generators (72 FR 4442). Specifically, the January 31
final rule:
(1) Requires cylinders of compressed oxygen and other oxidizing
gases and packages of chemical oxygen generators to be placed in an
outer packaging that meets certain flame penetration and thermal
resistance requirements when transported aboard an aircraft;
(2) Revises the pressure relief device (PRD) setting limit on
cylinders of compressed oxygen and other oxidizing gases transported
aboard aircraft;
(3) Limits the types of cylinders authorized for transporting
compressed oxygen aboard aircraft; and
(4) Converts most of the provisions of an oxygen generator approval
into requirements in the HMR.
II. Appeals
The following organizations submitted appeals to the January 31
final rule, in accordance with 49 CFR part 106: Air Canada (AC); Barlen
and Associates, Inc. (Barlen); PSI Plus, Inc. (PSI); and United
Airlines, Inc. (United). Delta Airlines (Delta) also submitted a letter
expressing its general support for United's formal appeal. The
appellants based their appeals on several aspects of the January 31
final rule, most notably, the effective date of certain requirements in
the rule, cost and availability of the required outer packaging,
marking requirements, and thermal resistance testing. We also received
requests for clarification of certain requirements of the January 31
final rule. The Good View Trading Company (GVT) also expressed concerns
about the impact the January 31 final rule will have on the current
exceptions for live fish transported aboard aircraft.
In this final rule, we are granting the request to delay the
mandatory effective date from October 1, 2007 until October 1, 2008 to
require a new limit on the pressure relief device (PRD) settings on
cylinders containing compressed oxygen or other oxidizing gases when
transported aboard aircraft. We are clarifying the thermal resistance
test methods for packagings for oxygen cylinders and oxygen generators
in Appendix D to part 178. We are granting the request to include DOT
specification 3E and 39 cylinders among the types of cylinders
authorized for the transportation of compressed oxygen and other
oxidizing gases aboard aircraft. In addition, we are providing a
marking option to ensure easier identification of cylinders equipped
with the new PRD and outer packagings meeting the flame penetration and
thermal resistance requirements. The appeals and issues of the
appellants and other concerned parties are discussed in detail below.
A. Outer Packaging That Meets Certain Flame Penetration and Thermal
Resistance Requirements When Transported Aboard Aircraft
The January 31 final rule amended the HMR to require cylinders of
compressed oxygen and other oxidizing gases and chemical oxygen
generators to be transported in an outer packaging that: (1) Meets the
same flame penetration resistance standards as required for cargo
compartment sidewalls and ceiling panels in transport category
airplanes; and (2) provides certain thermal protection capabilities so
as to retain its contents during an otherwise controllable cargo
compartment fire. The outer packaging standard adopted in the January
31 final rule addresses two safety concerns: (1) Protecting a cylinder
and an oxygen generator that could be exposed directly to flames from a
fire; and (2) protecting a cylinder and an oxygen generator that could
be exposed indirectly to heat from a fire. These performance
requirements must remain in effect for the entire service life of the
outer packaging.
Under the January 31 final rule, an outer packaging for a cylinder
containing compressed oxygen or another oxidizing gas and a package
containing an oxygen generator must meet the standards in Part III of
Appendix F to 14 CFR part 25, Test Method to Determine Flame
Penetration Resistance of Cargo Compartment Liners. An outer
packaging's materials of construction must prevent penetration by a
flame of 1,700 [deg]F for five minutes, in accordance with Part III of
Appendix F, paragraphs (a)(3) and (f)(5) of 14 CFR part 25. A method
for thermal resistance testing of packagings for oxygen cylinders and
oxygen generators was added by the January 31 final rule under a new
Appendix D to part 178 of the HMR. To ease understanding of and
compliance with the flame penetration test requirements, in this final
rule we are adding a new Appendix E to part 178, which will include the
entire test procedure. This will eliminate the necessity for persons
performing the flame penetration test to refer to the requirements in
Appendix F to 14 CFR part 25.
In its appeal, United expresses concern about several aspects of
these provisions, including international repercussions, risk
assessment and analysis, effects of this rulemaking on travelers
requiring medical oxygen, and the cost basis for the packaging required
by the January 31 final rule.
[[Page 55093]]
Specifically, United contends that no test data or other substantiation
of compliance with requirements for outer packaging by any packaging
manufacturer was placed in the public docket. United also states that
although the January 31 final rule indicates at least one packaging
manufacturer appears to have addressed the flame penetration and
thermal penetration standard and is able to produce the required
packaging, neither this company nor any other has actually produced it.
In addition, United contends that because the packaging required by the
January 31 final rule does not yet exist, the cost estimates made by
the agency are unreliable.
We are not persuaded that the required packagings will be
unavailable or that we have underestimated the cost of bringing them to
market. PHMSA issued the January 31 final rule only after reviewing
test data and other materials substantiating the development of
packagings meeting the performance standard. Based on consultation with
companies that are able to produce similar packaging and reviewing
their packaging prototypes, supporting test documentation and cost
estimates, we believe the required packaging will be available in
sufficient time for the affected parties to comply with this
requirement. (Because of its confidential proprietary nature, we did
not post this documentation in the public docket for this rulemaking.)
PHMSA and FAA intend to closely monitor the availability of the
required packaging as the effective date of this provision approaches
and will consider an extension of the compliance date for this
requirement if it is determined that a sufficient supply of the
required outer packaging is not available.
Likewise, the fact that the required packaging is not yet
commercially available does not make the cost estimates for this
rulemaking unreasonable. As referenced in the January 31 final rule,
packaging manufacturers provided estimates of costs for the existing
ATA specification 300 packagings and the new outer packaging. We
utilized these estimates, in addition to our own research, in the
regulatory evaluation (available for review in the public docket for
this rulemaking). Although some of the figures provided by the
commenters were slightly higher than ours, the differences were not
significant. Accordingly, we believe that our estimate of a total cost
of $10.8 million ($7.6 million discounted to present value) over 15
years, for the transport of oxygen cylinders, and $27.0 million ($16.9
million discounted to present value) over 15 years, for the costs
associated with the transport of chemical oxygen generators, are
reasonable estimates of the costs of this rulemaking despite the
current lack of an available outer packaging in an after-market
condition.
United also refers to the statement in the January 31 final rule
that DOT intends to submit a paper to the International Civil Aviation
Organization (ICAO) Dangerous Goods Panel to propose that the ICAO
Technical Instructions be amended consistent with the requirements of
the packaging required by the January 31 rulemaking. United requests
that a copy of such a U.S. proposal be placed in the public docket for
HM-224B, and that the views of other air carriers in the international
community be considered. United states that PHMSA should collect input
from the international community before concluding rulemaking action in
this docket because of the international aviation environment and
PHMSA's expressed stance on the benefits of global harmonization.
United also recommends that if the new requirements are adopted
internationally through ICAO, the compliance dates for affected
carriers should coincide to avoid unnecessary compliance complexity in
the aviation industry.
We agree that the international community should be considered when
initiating any regulatory change that could potentially affect
international commerce. As indicated in the January 31 final rule, it
was PHMSA's intention to submit a working paper pertaining to this
rulemaking for discussion at the meeting of the ICAO Dangerous Goods
Panel (DGP). PHMSA submitted a paper to the DGP Working Group of the
Whole (held April 30 to May 4, 2007) which provided information
relative to the amendments to the HMR to enhance the requirements for
the transportation of compressed oxygen, other oxidizing gases and
chemical oxygen generators on aircraft. The working paper can be viewed
on the public ICAO Web site at: https://www.icao.int/anb/FLS/
DangerousGoods/FLSDG.cfm. A copy of this working paper has also been
placed in the public docket for this rulemaking. However, we are not
prepared to defer this rulemaking while changes to international
standards are considered. As we explained in the January 31 final rule,
the risk of an unintentional actuation of an oxygen generator or a
cylinder containing oxygen or another oxidizing gas during an aircraft
fire is a serious safety risk that we believe must be immediately
addressed, without waiting for the outcome of international
deliberations.
United also contends that the final rule is inconsistent with
PHMSA's expressed commitment to promote risk-based, data-driven, and
cost-effective standards. United asserts that PHMSA justified the
January 31 rulemaking on a worst-case scenario that was not supported
by actual data in the record and that affected parties therefore should
be given time to review and comment on such data. As explained in the
January 31 final rule, we have utilized a risk-based approach to the
air transportation of compressed oxygen cylinders and oxygen generators
since the tragic events of the ValuJet Airlines crash in 1996. FAA has
established through testing that cylinders of compressed oxygen release
their contents at temperatures well below those that aircraft cargo
compartment liners and structures are designed to withstand. When the
surface temperature of a cylinder of compressed oxygen reaches
approximately 300 [deg]F, the increase in internal pressure causes the
cylinder's pressure relief device to open and release oxygen. The risk
that such a release could vent directly into a fire significantly
increases the risks posed by aircraft fires. FAA also found that use of
an outer packaging specifically designed to provide both thermal
protection and flame penetration may significantly lengthen the time a
cylinder will retain its contents when exposed to fire or heat.
Therefore, our rationale for this January 31 final rule is a
continuation of our ongoing risk-based approach and is centered on the
conclusions drawn from the ``Evaluation of Oxygen Cylinder Overpacks
Exposed to Elevated Temperatures'' conducted by FAA (available for
review in the public docket for this rulemaking).
United also contends that PHMSA did not adequately address the
potential of the new packaging requirements to restrict air travel by
individuals who need compressed oxygen to travel. It states that
additional packaging cost and other related costs could dissuade air
carriers from providing this service. The commenter also states that
although PHMSA requested information on this scenario in the January 31
final rule, the impact could not be considered sufficiently without
adequate and reliable information on the cost of the required
packaging.
PHMSA is acutely aware of the specific needs of individuals who
require compressed oxygen to travel, and has maintained ongoing
dialogue with FAA and other agencies in an attempt to minimize
requirements that
[[Page 55094]]
may restrict their travel. For example, PHMSA and FAA have partnered
with the Office of the Secretary of Transportation to develop a
rulemaking that proposes to provide greater accommodations for persons
with respiratory disabilities, and provide passengers free in-flight
medical oxygen in accordance with applicable safety rules. See
``Nondiscrimination on the Basis of Disability in Air Travel--Medical
Oxygen and Portable Respiration Assistive Devices,'' Docket No. OST-
2005-22298, 70 FR 53108 (September 7, 2005), 70 FR 61241 (October 21,
2005).
The January 31 final rule complements the goal of providing a safer
environment for people with disabilities by requiring cylinders of
compressed oxygen and other oxidizing gases and packages of chemical
oxygen generators to be placed in an outer packaging that meets certain
flame penetration and thermal resistance requirements when transported
aboard an aircraft. We note that the current regulations specified in
Sec. 175.501 of the HMR allow for the use of oxygen by passengers in
the aircraft cabin and provide for the stowage of a combined total of
six cylinders of compressed oxygen, which, under the conditions
specified in this section, do not require that they be placed in the
new outer packaging.
For the reasons cited above, the appeal to the requirement that an
outer packaging for a cylinder containing compressed oxygen or another
oxidizing gas and a package containing an oxygen generator must meet
the standards adopted in the January 31 final rule is denied.
B. Test Method in Appendix D to Part 178 and Test Protocol for Outer
Packaging
The January 31 final rule amended the HMR by adding a thermal
resistance test for packagings for oxygen cylinders and oxygen
generators in a new appendix (Appendix D) to part 178. United
recommends that PHMSA clarify the test method described in Paragraph
4.1 of this appendix, which states, ``It is recommended that the
cylinder be closed at ambient temperature and configured as when filled
with a valve and pressure relief device. The oxygen generator must be
filled and may be tested with or without packaging.'' United indicates
that it understands from discussions that took place with PHMSA and its
trade association after publication of the January 31 final rule that
PHMSA did not intend to require testing of the outer packaging with
inner receptacles containing hazardous materials. If an alternative
filling material was intended, the commenter requests PHMSA clarify
this portion of the appendix as applicable. United suggests that ``any
alternate material should exhibit comparable heat-absorbing properties
of compressed oxygen in the cylinder, or oxidizing solid in the
generator.'' If, however, oven testing with packagings containing
hazardous materials is required, the commenter is uncertain there is a
testing facility capable of performing such a test.
In publishing the January 31 final rule, it was our intention to
permit the thermal resistance test to be conducted on an oxygen
cylinder that is either empty or filled with nitrogen. It was also our
intention that an oxygen generator must be tested completely filled
with its oxidizing agent. Therefore, in this final rule, we are
granting United's request to clarify the test method described in
Appendix D to Part 178. In addition, we are also providing an
alternative to the use of thermocouples specified in the test methods
of Appendix D to part 178.
United also expresses concern that the test protocol for outer
packaging required by the January 31 final rule will change in the near
future. For example, the commenter points out the footnote in the
preamble at page 4444 of the January 31 final rule:
The FAA is currently evaluating other non-ozone-depleting
suppression agents that could eventually be used in cargo
compartments. Some of these agents can maintain an adequate level of
safety in the compartment, but the mean temperature may be slightly
higher than 400 [deg]F, which is the level found during typical
halon-suppressed fires. If an alternative agent is used, the oven
soak temperature level may need to be adjusted accordingly.
United states that the investment by itself and other air carriers
in the newly required outer packaging is too substantial for the test
performance temperature to be addressed in such vague terms. The
commenter requests clarification of this statement and an assessment of
the probability that it will result in a revision to the performance
standard for outer packaging by, or relatively soon after, the October
1, 2007 mandatory compliance date.
We understand the commenter's concern regarding the footnote on
page 4444 of the January 31 final rule which references FAA's ongoing
evaluation of other non-ozone-depleting suppression agents that could
eventually be used in cargo compartments. By including the footnote,
our intention was to provide additional information about testing
agents currently under consideration which may affect test performance
temperatures. For clarification, FAA's halon replacement program was
designed to develop minimum performance standards (MPS) for the various
extinguishing systems used aboard aircraft. These MPS would establish a
baseline test for new agents to demonstrate that the agent had
comparable fire-fighting effectiveness to that of Halon 1211 and 1301.
FAA has developed the MPS for hand-held fire extinguishers, waste bins,
and cargo compartments. In addition, three halocarbon agents have been
approved for use in hand-held fire extinguishers. While alternative
agents are currently being evaluated, none have been approved for use
on aircraft. Further, the FAA informs us that it has no plans at
present to mandate the use of halon replacements. Therefore, we do not
anticipate that a revision to the test protocol for outer packaging
required by the January 31 final rule will occur in the near future.
C. Effective Date for Pressure Relief Device Settings on Cylinders of
Compressed Oxygen and Other Oxidizing Gases
The January 31 final rule revised the HMR to require a new limit on
the pressure relief device (PRD) settings on cylinders containing
compressed oxygen or other oxidizing gases when transported aboard
aircraft. To ensure the cylinder contents are not released into an
aircraft cargo compartment in the event of a fire, we amended the HMR
to limit the PRD to a setting that will prevent it from releasing at
temperatures the cylinder will experience while protected by the outer
packaging. We also amended the HMR to require cylinders containing
oxidizing gases, including oxygen, be equipped with PRDs that have a
set pressure equal to the cylinder test pressure with allowable
tolerances of -10 to plus zero percent. The effective date of this
requirement for cylinders containing compressed oxygen and oxidizing
gases was established in the January 31 final rule as the first
requalification test due after October 1, 2007.
United requests that PHMSA delay the mandatory effective date from
October 1, 2007 until October 1, 2008 in order to allow it and other
air carriers to come into compliance with this requirement of the
January 31 final rule. United states that ``after cylinder
manufacturers develop and implement new designs, conduct any required
testing, complete the detailed approval process, and [sic] manufacture
and distribute the new PRDs, it then will be
[[Page 55095]]
necessary to transport these cylinders as air cargo to assure global
distribution to all of United's facilities where replacements might
need to be installed, and to accommodate breathing-oxygen needs for
impaired passengers as part of United's current effort to serve such
customers.'' In addition, United states that procedures for oxygen
cylinder maintenance and quality assurance programs must be revised,
prompting additional training, testing and certification of both
employees and their supervisors, and that ``in addition to all the
cylinders that may come due for periodic retest as early as October 1,
2007, it is assumed that any new oxygen cylinders purchased as
replacement parts will need to be equipped with the new PRD as of that
date.'' United states the demand for PRDs will likely peak around the
October 1, 2007 effective date specified in the January 31 final rule,
and it foresees an inadequate supply of PRDs. The commenter further
states that it has over 6,500 cylinders affected by this rule and,
after discussions with the manufacturers of these cylinders and
external repair facilities, it is concerned that bringing its cylinders
into compliance with this requirement by the January 31 final rule
effective date will not be achievable.
We accept the likelihood that more time may be necessary to allow
for the testing, approval, distribution, and training associated with
this requirement of the January 31 final rule. Therefore, we are
extending the effective date for this provision from October 1, 2007
until October 1, 2008. By this revised date, the HMR requires a new
limit on the PRD settings on cylinders containing compressed oxygen or
other oxidizing gases when transported aboard aircraft. The effective
date of this requirement for cylinders containing compressed oxygen and
oxidizing gases is established as the first requalification test due
after October 1, 2008.
In the January 31 final rule, we added a new Sec. 173.168 that
would: (1) Specify the means to be incorporated into an oxygen
generator to prevent inadvertent actuation; (2) require the oxygen
generator to be capable of withstanding a 1.8 meter drop with no loss
of contents or actuation; and (3) specify packaging, shipping paper,
and marking requirements for those oxygen generators that are installed
in a piece of equipment sealed or otherwise packaged so it is difficult
to determine if an oxygen generator is present. The effective date of
these new requirements is October 1, 2007, except for the packaging
requirement in paragraph (d) of Sec. 173.168, which becomes effective
on September 30, 2009. We received a request for clarification
regarding these effective dates. One commenter requests clarification
as to whether the requirements prior to the January 31 final rule
pertaining to chemical oxygen generators, particularly approvals, were
intended to remain in effect until the effective date of the January 31
final rule. For clarification, our intention in the January 31 final
rule was for the current requirements concerning chemical oxygen
generators, including approvals, to remain in effect until the overall
effective date of the January 31 final rule. A similar issue was raised
by the same commenter concerning the additional requirements for
shipment of nonliquefied (permanent) and liquefied compressed gases in
specification cylinders found in Sec. Sec. 173.302a and 173.304a,
respectively. The commenter asks whether it was PHMSA's intention to
continue current outer packaging requirements for non-liquefied
(permanent) and liquefied compressed gases in specification cylinders
until the effective dates specified in these revised sections.
The answer is yes. It was also our intention in the January 31
final rule that the current requirements for the shipment of
nonliquefied and liquefied compressed gases in specification cylinders
remain in effect until the effective dates specified under these
revised sections. In this final rule, we are revising the amendments to
Sec. Sec. 173.302a and 173.304a to clarify these effective dates and
are re-designating them under new paragraph (f) of Sec. 173.302--
``Filling of cylinders with non-liquefied (permanent) compressed
gases--'' and new paragraph (f) of Sec. 173.304--``Filling of
cylinders with liquefied compressed gases--'' respectively, to provide
a more logical, user-friendly format. We are also revising Sec.
173.301 to direct the user to these new paragraphs.
D. Marking Requirements
United also urges PHMSA to take further steps to ensure easier
identification of cylinders equipped with the new PRD and outer
packagings meeting the flame penetration and thermal resistance
requirements. In its appeal, the commenter requests that PHMSA require
manufacturers to distinguish between the modified cylinders, as well as
the modified outer packaging, through the use of a uniform marking
requirement. United asserts that such a marking requirement would have
the benefit of clarifying DOT's jurisdiction over the manufacturers,
specifically with respect to compliance with testing, hazmat employee
training, and record-keeping provisions. In addition, United states
that a consistent visible mechanism will allow its employees and DOT
enforcement officials to determine whether a UN or ATA Specification
300 outer packaging meets the new rule versus prior requirements, and
to identify with reliable ease and certainty which DOT and UN cylinders
are authorized to transport specific hazardous materials by air. United
stresses the importance of such a provision because of the common
airline industry practice of conducting code share operations and
participating in loaned parts programs.
PHMSA acknowledges the commenters' concerns that current labeling
and marking requirements may not fully identify cylinders equipped with
the new PRD and outer packagings meeting the flame penetration and
thermal resistance requirements of the January 31 final rule. However,
because we did not propose any additional marking or labeling
requirements in the NPRM, we cannot formally adopt a uniform marking or
labeling requirement in this final rule. Any new marking or labeling
requirement must be proposed in a future rulemaking to allow for public
comment. Instead, PHMSA and FAA have developed a voluntary marking that
may be affixed to an outer packaging meeting the flame penetration and
thermal resistance requirements of the January 31 final rule to
indicate compliance with these provisions of the regulations. The
marking is as follows:
DOT31FP
We emphasize that this marking is not a requirement. We will
consider proposing this marking as a uniform marking requirement in a
future rulemaking, and, if this or some other marking is adopted, it
would be incorporated into the HMR as an acceptable indication that the
outer packaging meets the flame penetration and thermal resistance
requirements and is in compliance with the requirements of the January
31 final rule.
E. Authorized Cylinders for Compressed Oxygen and Other Oxidizing Gases
The January 31 final rule revised the HMR to limit cylinders
authorized for the transportation of compressed oxygen and other
oxidizing gases aboard aircraft to DOT specifications 3A, 3AA, 3AL, and
3HT in order to minimize numerous PRD setting requirements for oxygen
cylinders aboard aircraft.
Barlen comments that DOT 39 and DOT 3E cylinders are safer than 3AL
cylinders and questions why these
[[Page 55096]]
cylinders were eliminated in the January 31 final rule. PSI, a
manufacturer of high-pressure steel DOT 39 and DOT 3E cylinders,
requests reconsideration of the requirement to limit cylinders
authorized for the transportation of compressed oxygen aboard aircraft
and a delay in implementation of the requirements of the January 31
final rule. This commenter states the majority of the cylinders it
manufactures are sold to companies producing gas mixtures used for gas
calibration equipment and medical devices, such as blood gas analyzers.
PSI notes that although DOT 3A and DOT 3AA cylinders are allowed in the
January 31 final rule, these cylinders are not used for calibration gas
mixtures because of their excessive weight. The commenter asserts that
the requirements in the January 31 final rule would effectively ban the
use of the only cylinders it manufactures. PSI adds that testing has
shown steel DOT 39 and DOT 3E cylinders will survive fires for longer
periods of time and be more resistant to higher failure temperatures
than aluminum 3AL cylinders, and, along with Barlen, requests DOT to
consider permitting the use of these cylinder types in addition to the
DOT 3AL cylinders specified in the January 31 final rule. In addition,
PSI requests DOT to allow limited quantities of oxygen-rich calibration
gas mixtures to be transported on non-passenger aircraft such as those
operated by Federal Express and UPS. Finally, PSI requests a delay in
the implementation of this rule to allow for presentation of additional
information.
We agree with the commenters that including DOT 39 and DOT 3E
cylinders as cylinders authorized for the transportation of compressed
oxygen and other oxidizing gases aboard aircraft does not pose an
additional safety hazard and will provide carriers more flexibility
when transporting these materials aboard aircraft. Therefore, we are
revising the HMR to limit cylinders authorized for the transportation
of compressed oxygen and other oxidizing gases aboard aircraft to DOT
specifications 39, 3A, 3AA, 3AL, 3E, and 3HT, and UN pressure
receptacles ISO 9809-1, ISO 9809-2, ISO 9809-3 and ISO 7866 cylinders,
including a new limit on the PRD settings.
F. Miscellaneous Issues
Currently, Sec. 173.302(c) specifies that an authorized cylinder
containing oxygen continuously fed to tanks containing live fish may be
offered for transportation and transported. One commenter, the Good
View Trading Company (GVT), expresses concern about the impact that the
new outer packaging requirement in the January 31 final rule will have
on the current exceptions for live fish transported aboard aircraft. In
publishing the January 31 final rule, our intention was not to
eliminate this exception. Therefore, for clarification, we are revising
this section to specifically except it from the new outer packaging
requirements.
In addition, on May 3, 2007, PHMSA published a final rule under
Docket No. PHMSA-2005-23141 (HM-215F) in the Federal Register (72 FR
25161). The HM-215F final rule amended the HMR to revise and
consolidate the requirements applicable to the use of the International
Civil Aviation Organization's Technical Instructions for the Safe
Transport of Dangerous Goods by Air, the International Maritime
Dangerous Goods Code, Transport Canada's Transportation of Dangerous
Goods Regulations, and the International Atomic Energy Agency's Safety
Standards Series: Regulations for the Safe Transport of Radioactive
Material. The revisions and reformatting provide a user-friendly format
to promote understanding of the conditions and limitations on the use
of international standards and regulations. In the HM-215F final rule,
the ICAO Technical Instructions (formerly Sec. 171.11) were re-
designated as new Sec. 171.24. As a result of this designation, the
revisions adopted in this section under the January 31 final rule were
inadvertently omitted. Therefore, we are republishing new Sec. 171.24
as amended in the January 31 final rule for clarification.
III. Regulatory Analyses and Notices
A. Statutory/Legal Authority for Rulemaking
This final rule is published under the authority of Federal
hazardous materials transportation law (Federal hazmat law; 49 U.S.C.
5101 et seq.). Section 5103(b) of Federal hazmat law authorizes the
Secretary of Transportation to prescribe regulations for the safe
transportation, including security, of hazardous material in
intrastate, interstate, and foreign commerce.
B. Executive Order 12866 and DOT Regulatory Policies and Procedures
This final rule is not a significant action under section 3(f) of
Executive Order 12866 and was not reviewed by the Office of Management
and Budget. This final rule is not a significant action under the
Regulatory Policies and Procedures of the Department of Transportation.
The revisions adopted in this final rule do not alter the cost-benefit
analysis and conclusions contained in the Regulatory Evaluation
prepared for the January 31, 2007 final rule. The Regulatory Evaluation
is available for review in the public docket for this rulemaking.
C. Executive Order 13132
This final rule has been analyzed in accordance with the principles
and criteria contained in Executive Order 13132 (``Federalism''). This
final rule preempts State, local and Indian tribe requirements, but
does not amend any regulation that has direct effects on the States,
the relationship between the national government and the States, or the
distribution of power and responsibilities among the various levels of
government. Therefore, the consultation and funding requirements of
Executive Order 13132 do not apply.
The Federal hazardous materials transportation law, 49 U.S.C. 5101-
5127, contains an express preemption provision (49 U.S.C. 5125(b)) that
preempts State, local, and Indian tribe requirements on the following
subjects:
(1) The designation, description, and classification of hazardous
material;
(2) The packing, repacking, handling, labeling, marking, and
placarding of hazardous material;
(3) The preparation, execution, and use of shipping documents
related to hazardous material and requirements related to the number,
contents, and placement of those documents;
(4) The written notification, recording, and reporting of the
unintentional release in transportation of hazardous material; and
(5) The design, manufacture, fabrication, marking, maintenance,
recondition, repair, or testing of a packaging or container
represented, marked, certified, or sold as qualified for use in
transporting hazardous material.
This final rule addresses items 2 and 5 above and preempts any
State, local, or Indian tribe requirements not meeting the
``substantially the same'' standard.
Federal hazardous materials transportation law provides at Sec.
5125(b)(2) that, if DOT issues a regulation concerning any of the
covered subjects, DOT must determine and publish in the Federal
Register the effective date of Federal preemption. The effective date
may not be earlier than the 90th day following the date of issuance of
the final rule and not later than two years after the date of issuance.
This effective date of preemption is 90 days after the publication of
this final rule in the Federal Register.
[[Page 55097]]
D. Executive Order 13175
This final rule has been analyzed in accordance with the principles
and criteria contained in Executive order 13175 (``Consultation and
Coordination with Indian Tribal Governments''). Because this final rule
will not have tribal implications, does not impose substantial direct
compliance costs on Indian tribal governments, and does not preempt
tribal law, the funding and consultation requirements of Executive
Order 13175 do not apply, and a tribal summary impact statement is not
required.
E. Regulatory Flexibility Act, Executive Order 13272, and DOT
Procedures and Policies
The Regulatory Flexibility Act of 1980 requires an agency to review
regulations to assess their impact on small entities unless the agency
determines that a rule is not expected to have a significant impact on
a substantial number of small entities. This final rule will not impose
increased compliance costs on the regulated industry. The revisions,
clarifications, and corrections we are making to the January 31, 2007
final rule will provide regulatory relief to persons transporting
compressed oxygen, other oxidizing gases and chemical oxygen generators
on aircraft by: Delaying the mandatory effective date from October 1,
2007 until October 1, 2008 to require a new limit on the pressure
relief device (PRD) settings on cylinders containing compressed oxygen
or other oxidizing gases when transported aboard aircraft; clarifying
the thermal resistance test methods for packagings for oxygen cylinders
and oxygen generators in Appendix D to Part 178, including DOT
specification 3E and 39 cylinders to the types of cylinders authorized
for the transportation of compressed oxygen and other oxidizing gases
aboard aircraft; and providing a marking option to ensure easier
identification of cylinders equipped with the new PRD and outer
packagings meeting the flame penetration and thermal resistance
requirements. Thus, DOT has determined that this final rule will not
have a significant impact on a substantial number of small entities.
Accordingly, pursuant to the Regulatory Flexibility Act, 5 U.S.C.
605(b), DOT certifies that this rule will not have a significant
economic impact on a substantial number of small entities. Therefore, I
certify that this rule will not have a significant economic impact on a
substantial number of small entities.
This final rule has been developed in accordance with Executive
Order 13272 (``Proper Consideration of Small Entities in Agency
Rulemaking'') and DOT's procedures and policies to promote compliance
with the Regulatory Flexibility Act to ensure that potential impacts of
draft rules on small entities are properly considered.
F. Unfunded Mandates Reform Act of 1995
The Unfunded Mandates Reform Act of 1995 (the Act) is intended,
among other things, to curb the practice of imposing unfunded Federal
mandates on State, local, and tribal governments. Title II of the Act
requires each Federal agency to prepare a written statement assessing
the effects of any Federal mandate in a proposed or final agency rule
that may result in an expenditure of $100 million or more (adjusted
annually for inflation) in any one year by State, local, and tribal
governments, in the aggregate, or by the private sector; such a mandate
is deemed to be a ``significant regulatory action.'' The FAA currently
uses an inflation-adjusted value of $128.1 million in lieu of $100
million.
This final rule does not contain such a mandate. The requirements
of Title II do not apply.
G. Paperwork Reduction Act
PHMSA currently has approved information collections under OMB
Control Number 2137-0572, ``Testing Requirements for Non-Bulk
Packaging'' with an expiration date of March 31, 2010, and OMB Control
Number 2137-0557, ``Approvals for Hazardous Materials'' with an
expiration date of March 31, 2008. This final rule imposes no new
information collection and recordkeeping requirements.
H. Regulation Identifier Number (RIN)
A regulation identifier number (RIN) is assigned to each regulatory
action listed in the Unified Agenda of Federal Regulations. The
Regulatory Information Service Center publishes the Unified Agenda in
April and October of each year. The RIN number contained in the heading
of this document can be used to cross-reference this action with the
Unified Agenda.

2.2 Thermocouples. At least three thermocouples must be used to
monitor the temperature inside the oven and an additional three
thermocouples must be used to monitor the temperature of the
cylinder. The thermocouples must be \1/16\ inch, ceramic packed,
metal sheathed, type K (Chromel-Alumel), grounded junction with a
nominal 30 American wire gauge (AWG) size conductor. The
thermocouples measuring the temperature inside the oven must be
placed at varying heights to ensure even temperature and proper
heat-soak conditions. For the thermocouples measuring the
temperature of the cylinder: (1) Two of them must be placed on the
outer cylinder side wall at approximately 2 inches (5 cm) from the
top and bottom shoulders of the cylinder; and (2) one must be placed
on the cylinder valve body near the pressure relief device.
Alternatively, the thermocouples may be replaced with other devices
such as a remote temperature sensor, metal fuse on the valve, or
coated wax, provided the device is tested and the test report is
retained for verification. Under this alternative, it is permissible
to record the highest temperature to which the cylinder is subjected
instead of temperature measurements in intervals of not more than
five (5) minutes.

14. A new Appendix E to part 178 is added to read as follows:
Appendix E to Part 178--Flame Penetration Resistance Test
(a) Criteria for Acceptance. (1) At least three specimens of the
outer packaging materials must be tested;
(2) Each test must be conducted on a flat 16 inch x 24 inch test
specimen mounted in the horizontal ceiling position of the test
apparatus to represent the outer packaging design;
(3) Testing must be conducted on all design features (latches,
seams, hinges, etc.) affecting the ability of the outer packaging to
safely prevent the passage of fire in the horizontal ceiling
position; and
(4) There must be no flame penetration of any specimen within 5
minutes after application of the flame source and the maximum
allowable temperature at a point 4 inches above the test specimen,
centered over the burner cone, must not exceed 205 [deg]C (400
[deg]F).
(b) Summary of Method. This method provides a laboratory test
procedure for measuring the capability of cargo compartment lining
materials to resist flame penetration with a 2 gallon per hour (GPH)
2 Grade kerosene or equivalent burner fire source. Ceiling
and sidewall liner panels may be tested individually provided a
baffle is used to simulate the missing panel. Any specimen that
passes the test as a ceiling liner panel may be used as a sidewall
liner panel.
(c) Test Specimens. (1) The specimen to be tested must measure
16 \1/8\ inches (406 3 mm) by 24+\1/8\
inches (610 3 mm).
(2) The specimens must be conditioned at 70 [deg]F. 5 [deg]F. (21 [deg]C. 2 [deg]C.) and 55% 5% humidity for at least 24 hours before testing.
(d) Test Apparatus. The arrangement of the test apparatus must
include the components described in this section. Minor details of
the apparatus may vary, depending on the model of the burner used.
(1) Specimen Mounting Stand. The mounting stand for the test
specimens consists of steel angles.
(2) Test Burner. The burner to be used in tesing must--
(i) Be a modified gun type.
(ii) Use a suitable nozzle and maintain fuel pressure to yield a
2 GPH fuel flow. For example: An 80 degree nozzle nominally rated at
2.25 GPH and operated at 85 pounds per square inch (PSI) gauge to
deliver 2.03 GPH.
(iii) Have a 12 inch (305 mm) burner extension installed at the
end of the draft tube with an opening 6 inches (152 mm) high and 11
inches (280 mm) wide.
(iv) Have a burner fuel pressure regulator that is adjusted to
deliver a nominal 2.0 GPH of 2 Grade kerosene or
equivalent.
Burner models which have been used successfully in testing are
the Lenox Model OB-32, Carlin Model 200 CRD and Park Model DPL.
(3) Calorimeter. (i) The calorimeter to be used in testing must
be a total heat flux Foil Type Gardon Gage of an appropriate range
(approximately 0 to 15.0 British thermal unit (BTU) per ft.\2\ sec.,
0-17.0 watts/cm\2\). The calorimeter must be mounted in a 6 inch by
12 inch (152 by 305 mm) by \3/4\ inch (19 mm) thick insulating block
which is attached to a steel angle bracket for placement in the test
stand during burner calibration as shown in Figure 2 of this part of
this appendix.
(ii) The insulating block must be monitored for deterioration
and the mounting shimmed as necessary to ensure that the calorimeter
face is parallel to the exit plane of the test burner cone.
(4) Thermocouples. The seven thermocouples to be used for
testing must be
[[Page 55100]]
\1/16\ inch ceramic sheathed, type K, grounded thermocouples with a
nominal 30 American wire gage (AWG) size conductor. The seven
thermocouples must be attached to a steel angle bracket to form a
thermocouple rake for placement in the test stand during burner
calibration.
(5) Apparatus Arrangement. The test burner must be mounted on a
suitable stand to position the exit of the burner cone a distance of
8 inches from the ceiling liner panel and 2 inches from the sidewall
liner panel. The burner stand should have the capability of allowing
the burner to be swung away from the test specimen during warm-up
periods.
(6) Instrumentation. A recording potentiometer or other suitable
instrument with an appropriate range must be used to measure and
record the outputs of the calorimeter and the thermocouples.
(7) Timing Device. A stopwatch or other device must be used to
measure the time of flame application and the time of flame
penetration, if it occurs.
(e) Preparation of Apparatus. Before calibration, all equipment
must be turned on and allowed to stabilize, and the burner fuel flow
must be adjusted as specified in paragraph (d)(2).
(f) Calibration. To ensure the proper thermal output of the
burner the following test must be made:
(1) Remove the burner extension from the end of the draft tube.
Turn on the blower portion of the burner without turning the fuel or
igniters on. Measure the air velocity using a hot wire anemometer in
the center of the draft tube across the face of the opening. Adjust
the damper such that the air velocity is in the range of 1550 to
1800 ft./min. If tabs are being used at the exit of the draft tube,
they must be removed prior to this measurement. Reinstall the draft
tube extension cone.
(2) Place the calorimeter on the test stand as shown in Figure 2
at a distance of 8 inches (203 mm) from the exit of the burner cone
to simulate the position of the horizontal test specimen.
(3) Turn on the burner, allow it to run for 2 minutes for warm-
up, and adjust the damper to produce a calorimeter reading of 8.0
0.5 BTU per ft.\2\ sec. (9.1 0.6 Watts/
cm\2\).
(4) Replace the calorimeter with the thermocouple rake.
(5) Turn on the burner and ensure that each of the seven
thermocouples reads 1700 [deg]F. 100 [deg]F. (927
[deg]C. 38 [deg]C.) to ensure steady state conditions
have been achieved. If the temperature is out of this range, repeat
steps 2 through 5 until proper readings are obtained.
(6) Turn off the burner and remove the thermocouple rake.
(7) Repeat (1) to ensure that the burner is in the correct
range.
(g) Test Procedure. (1) Mount a thermocouple of the same type as
that used for calibration at a distance of 4 inches (102 mm) above
the horizontal (ceiling) test specimen. The thermocouple should be
centered over the burner cone.
(2) Mount the test specimen on the test stand shown in Figure 1
in either the horizontal or vertical position. Mount the insulating
material in the other position.
(3) Position the burner so that flames will not impinge on the
specimen, turn the burner on, and allow it to run for 2 minutes.
Rotate the burner to apply the flame to the specimen and
simultaneously start the timing device.
(4) Expose the test specimen to the flame for 5 minutes and then
turn off the burner. The test may be terminated earlier if flame
penetration is observed.
(5) When testing ceiling liner panels, record the peak
temperature measured 4 inches above the sample.
(6) Record the time at which flame penetration occurs if
applicable.
(h) Test Report. The test report must include the following:
(1) A complete description of the materials tested including
type, manufacturer, thickness, and other appropriate data.
(2) Observations of the behavior of the test specimens during
flame exposure such as delamination, resin ignition, smoke, etc.,
including the time of such occurrence.
(3) The time at which flame penetration occurs, if applicable,
for each of the three specimens tested.
