quires recharging must be filled in ac-
cordance with § 173.301(l).
c. Every installed inflation cylinder, as as-
sociated equipment of the life-saving ap-
pliance, must be packed within the pro-
tective packaging of the life raft and the
life raft itself must otherwise be in com-
pliance with § 173.219.
d. The serial number for each cylinder
must be recorded as part of the life-sav-
ing appliance service record by the U.S.
Coast Guard-approved servicing facility.

This entry applies only to the vessel
transportation of nickel-metal hydride
batteries as cargo. Nickel-metal hydride
button cells or nickel-metal hydride cells
or batteries packed with or contained in
battery-powered devices transported by
vessel are not subject to the requirements
of this special provision.
See
‘‘Batteries,
dry, sealed, n.o.s.’’ in the § 172.101 Haz-
ardous Materials Table (HMT) of this part
for transportation requirements for nickel-
metal hydride batteries transported by
other modes and for nickel-metal hydride
button cells or nickel-metal hydride cells
or batteries packed with or contained in
battery-powered devices transported by
vessel. Nickel-metal hydride batteries sub-
ject to this special provision are subject
only to the following requirements: (1) The
batteries must be prepared and packaged
for transport in a manner to prevent a dan-
gerous evolution of heat, short circuits,
and damage to terminals; and are subject
to the incident reporting in accordance
with § 171.16 of this subchapter if a fire, vio-
lent rupture, explosion or dangerous evo-
lution of heat (
i.e.,
an amount of heat suffi-
cient to be dangerous to packaging or per-
sonal safety to include charring of pack-
aging, melting of packaging, scorching of
packaging, or other evidence) occurs as a
direct result of a nickel metal hydride bat-
tery; and (2) when loaded in a cargo trans-
port unit in a total quantity of 100 kg gross
mass or more, the shipping paper require-
ments of Subpart C of this part, the mani-
fest requirements of § 176.30 of this sub-
chapter, and the vessel stowage require-
ments assigned to this entry in Column
(10) of the § 172.101 Hazardous Materials
Table.
342 Glass inner packagings (such as ampoules
or capsules) intended only for use in steri-
lization devices, when containing less than
30 mL of ethylene oxide per inner pack-
aging with not more than 300 mL per outer
packaging, may be transported in accord-
ance with § 173.4a of this subchapter, irre-
spective of the restriction of § 173.4a(b) and
the indication of ‘‘forbidden’’ in columns
(9A) and (9B) of the § 172.101 table provided
that:
a. After filling, each glass inner packaging
must be determined to be leak-tight by
placing the glass inner packaging in a
hot water bath at a temperature and for
a period of time sufficient to ensure that
an internal pressure equal to the vapor
pressure of ethylene oxide at 55
°
C is
achieved. Any glass inner packaging
showing evidence of leakage, distortion
or other defect under this test must not
be transported under the terms of this
special provision;
b. In addition to the packaging required in
§ 173.4a, each glass inner packaging must
be placed in a sealed plastic bag compat-
ible with ethylene oxide and capable of
containing the contents in the event of
breakage or leakage of the glass inner
packaging; and
c. Each glass inner packaging is protected
by a means of preventing puncture of the
plastic bag (
e.g.,
sleeves or cushioning) in
the event of damage to the packaging
(
e.g.,
by crushing).
343
A bulk packaging that emits hydrogen
sulfide in sufficient concentration that va-
pors evolved from the crude oil can present
an inhalation hazard must be marked as
specified in § 172.327of this part.

‘‘Nitrogen, refrigerated liquid (
cryogenic
liquid
), UN1977’’ transported in open cryo-
genic receptacles with a maximum capac-
ity of 1 L are not subject to the require-
ments of this subchapter. The receptacles
must be constructed with glass double
walls having the space between the walls
vacuum insulated and each receptacle
must be transported in an outer packaging
with sufficient cushioning and absorbent
materials to protect the receptacle from
damage.
346
‘‘Nitrogen, refrigerated liquid (
cryogenic
liquid
), UN1977’’ transported in accordance
with the requirements for open cryogenic
receptacles in § 173.320 and this special pro-
vision are not subject to any other require-
ments of this subchapter. The receptacle
must contain no hazardous materials other
than the liquid nitrogen which must be
fully absorbed in a porous material in the
receptacle.

Effective July 1, 2011, for transportation
by aircraft, this entry may only be used if
the results of Test series 6(d) of Part I of
the UN Manual of Tests and Criteria (IBR,
see
§ 171.7 of this subchapter) have dem-
onstrated that any hazardous effects from
accidental functioning are confined to
within the package. Effective January 1,
2012, for transportation by vessel, this
entry may only be used if the results of
Test Series 6(d) of Part I of the UN Manual
of Tests and Criteria (IBR,
