Hazardous Materials: Shipping Description and Packaging of Oxygen
Generators; Delay of Effective Date, Technical Amendments and
Corrections
AGENCY: Research and Special Programs Administration (RSPA), DOT.
ACTION: Final rule; delay of effective date, technical amendments and
corrections.
-----------------------------------------------------------------------
SUMMARY: On June 5, 1997, RSPA published a final rule which amended the
Hazardous Materials Regulations by adding a specific shipping
description to the Hazardous Materials Table for chemical oxygen
generators. In this revision to the final rule, RSPA is delaying the
effective date of the final rule for one month, authorizing permissive
compliance immediately, correcting the identification number for
chemical oxygen generators and a typographic error in the Hazardous
Materials Table entry for them, and revising Special provision 60 for
clarity and to provide additional time to conform to additional
approval procedures.
DATES: Effective dates: The effective date for the final rule published
at 62 FR 30767 under Docket HM-224A on June 5, 1997, is delayed from
July 7, 1997 to August 7, 1997. The amendments and corrections in this
final rule are effective August 7, 1997.
Applicability: The provisions of Sec. 172.101(l)(1)(ii), which
otherwise would allow up to one year after a change in the Hazardous
Materials Table to use up stocks of preprinted shipping papers and to
ship packages that were marked prior to the change, do not apply to
these amendments and corrections.
Permissive compliance date: Compliance with the requirements
adopted in this final rule and in the final rule published at 62 FR
30767 is authorized immediately.

SUPPLEMENTARY INFORMATION: A final rule was published in the Federal
Register on June 5, 1997 (62 FR 30767) under Docket HM-224A. In the
final rule, RSPA amended the Hazardous Materials Regulations (49 CFR
parts 171-180; HMR) by adding a specific shipping description to the
Hazardous Materials Table in Sec. 172.101 for chemical oxygen
generators and requiring approval of a chemical oxygen generator,
including its packaging, when it is to be transported with its means of
initiation attached. In this document, RSPA is making editorial and
technical revisions which it believes necessary to correct or clarify
the final rule and facilitate compliance with its provisions. The
changes respond to telephone and written comments RSPA has received
concerning the June 5, 1997 final rule.
Effective Date and Permissive Compliance Date
The effective date for compliance with the June 5, 1997 final rule
is delayed from July 7, 1997 to August 7, 1997 and the amendments in
this final rule also are made effective August 7, 1997. RSPA believes
that this one month delay of the effective date is necessary to provide
adequate time for shippers to identify and mark previously packaged
chemical oxygen generators and to implement the marking requirement for
current production.
RSPA is authorizing permissive compliance immediately and strongly
encourages shippers of chemical oxygen generators to comply immediately
with the new shipping description requirements. The Federal Aviation
Administration has advised RSPA that lack of a shipping description in
the HMR is contributing to confusion in the transportation of chemical
oxygen generators and has resulted in their unauthorized transportation
in certain instances.
Shipping Description
The identification number for oxygen generator, chemical, in the
Hazardous Materials Table in Sec. 172.101 was incorrectly identified in
the final rule as ``UN3353''. Therefore, RSPA is correcting the
identification number to read ``UN3356'' consistent with the United
Nations Recommendations on the Transport of Dangerous Goods.
RSPA is removing the Packing Group I entry for ``Oxygen generators,
chemical''. Although some of the oxidizing materials used in oxygen
generators may be in Packing Group I, RSPA believes the Packing Group
II designation adequately identifies the level of risk posed by these
devices and is desirable for consistency with provisions adopted for
inclusion in the Technical Instructions for the Safe Transport of
Dangerous Goods by Air of the International Civil Aviation Organization
(ICAO Technical Instructions). In addition, the table entry under
column 10A is corrected to read ``D.''
Special Provision 60
RSPA is providing for a delay, until October 1, 1997, in mandatory
compliance with Special Provision 60 so that persons who offer
generators (including company materials) may obtain any new or revised
approvals needed to comply with the requirements of the special
provision. RSPA is revising the special provision to clarify that a
copy of an approval must be maintained at each facility where a
chemical oxygen generator is packaged, rather than where it is
``prepared for shipment''. Also, RSPA is clarifying that the approval
requirements apply to any chemical oxygen generator that is shipped
with its means of initiation attached and that, if the means of
initiation involve use of an explosive (e.g., a primer or an electric
match), the approval procedures of Sec. 173.56 must be followed.
Historically, all new explosives, including devices such as
chemical oxygen generators which contain an explosive means of ignition
(e.g., a primer or an electric match), must be examined by an agency
designated by the Associate Administrator for Hazardous Materials
Safety (Associate Administrator) and classed and approved by the
Associate Administrator before being offered for transportation (see
Sec. 173.56). Otherwise the explosive device is a ``Forbidden
explosive'' and may not be offered for transportation or transported,
as specified in Secs. 173.21 and 173.54. RSPA is aware that some of
these past approvals for chemical oxygen generators may not have
included a requirement for at least two positive means of preventing
unintentional activation as required by the June 5, 1997 final rule,
and that some older approvals which were issued by the Bureau of
Explosives may not have approval numbers assigned to them. There also
may be chemical oxygen generators which are initiated with other than
an explosive means, and these generators would not have needed an
approval prior to the June 5, 1997 final rule. For these reasons, RSPA
believes a delay in the implementation date for the new approval
procedures is warranted.
RSPA emphasizes that if the original approval for a chemical oxygen
generator specifies a specific packaging configuration as a condition
of the approval, any change in the packaging configuration requires a
separate approval. RSPA expects strict conformance with the
requirements stated above, but also recognizes the burden involved in a
complete reexamination each time a generator containing an explosive
substance is modified. Accordingly, in administering Special Provision
60, the Associate Administrator will not require a complete
reexamination when a modification to an approved device or its
packaging is unrelated to the risk being addressed by the regulation
(e.g., a change in an oxygen outlet at the end opposite the initiating
device).
The reader is referred to the preamble discussion in the June 5,
1997, final rule under Docket HM-224A addressing approval requirements,
62 FR 30768-69.
ICAO Technical Instructions
Recently, provisions for chemical oxygen generators were adopted
for inclusion into the ICAO Technical Instructions. These provisions
include: (1) adding a shipping description; (2) forbidding the
transportation on passenger-carrying aircraft of chemical oxygen
generators; (3) forbidding the transportation on any aircraft of
chemical oxygen generators which have passed their expiration date or
which have been used; and, (4) adding a packing instruction for
chemical oxygen generators intended for transportation on cargo
aircraft. The major provisions of the packing instruction are as
follows:
Oxygen generator, chemical containing oxidizing substances must
meet all the following conditions:
(a) The generator, without its packaging, must be capable of
withstanding a 1.8m drop test on to a rigid, non-resilient, flat and
horizontal surface, in the position most likely to cause damage,
without loss of its contents and without actuation;
(b) When a generator is equipped with an actuating device, it must
have at least two positive means of preventing unintentional actuation;
(c) The generator(s) must be transported in a package which will
meet the following requirements when one generator in the package is
actuated:
(1) Other generators in the package will not be actuated;
(2) Packaging material will not ignite; and
(3) The outside surface temperature of the completed package must
not exceed 100 deg.C
[[Page 34669]]
(d) The generator(s) must be tightly packed in steel drums (1A2),
aluminum drums (1B2), plywood drums 1(D), fibre drums (1G), plastic
drums (1H2), steel jerricans (3A2), plastic jerricans (3H2), metal
boxes (4A, 4B), wooden boxes (4C1, 4C2), plywood boxes (4D),
reconstituted wood boxes (4F), fibreboard boxes (4G) or solid plastic
boxes (4H2).
RSPA expects that this packing instruction will become effective in
the ICAO Technical Instructions in the near future. RSPA anticipates
that any approval it issues under new Special Provision 60 for a
chemical oxygen generator intended for transportation aboard cargo
aircraft will require the chemical oxygen generator to be packaged in
accordance with the ICAO provisions.
