Section 175.10

49 CFR Ch. I (10-1-18 Edition)

(11) A single self-inflating personal
safety device such as a life jacket or
vest fitted with no more than two
small gas cartridges (containing no
hazardous material other than a Div.
2.2 gas) for inflation purposes plus no
more than two spare cartridges. The
personal safety device and spare cartridges may be carried in carry-on or
checked baggage, with the approval of
the aircraft operator, and must be
packed in such a manner that it cannot
be accidently activated.
(12) Small compressed gas cylinders
of Division 2.2 (containing no hazardous material other than a Division
2.2 gas) worn by the passenger for the
operation of mechanical limbs and, in
carry-on and checked baggage, spare
cylinders of a similar size for the same
purpose in sufficient quantities to ensure an adequate supply for the duration of the journey.
(13) A mercury barometer or thermometer carried as carry-on baggage,
by a representative of a government
weather bureau or similar official
agency, provided that individual advises the operator of the presence of
the barometer or thermometer in his
baggage. The barometer or thermometer must be packaged in a strong
packaging having a sealed inner liner
or bag of strong, leak proof and puncture-resistant material impervious to
mercury, which will prevent the escape
of mercury from the package in any position.
(14) Electrically powered heat-producing articles (e.g., battery-operated
equipment such as diving lamps and
soldering equipment) as checked or
carry-on baggage only and with the approval of the operator of the aircraft.
The heat-producing component, the energy source, or other component (e.g.,
fuse) must be removed to prevent unintentional functioning during transport.
Any battery that is removed must be
protected against short circuit by
placement in original retail packaging
or by otherwise insulating terminals
(e.g., by taping over exposed terminals
or placing each battery in a separate
plastic bag or protective pouch).
(15) A wheelchair or other batterypowered mobility aid equipped with a
nonspillable battery or a dry sealed

battery when carried as checked baggage, provided - 
(i) The battery conforms to the requirements of Section 173.159a(d) of this subchapter for non-spillable batteries;
(ii) The battery conforms to the requirements of Section 172.102(c)(1), Special
provision 130 of this subchapter for dry
sealed batteries, as applicable;
(iii) Visual inspection including removal of the battery, where necessary,
reveals no obvious defects (removal of
the battery from the housing should be
performed by qualified airline personnel only);
(iv) The battery is disconnected and
the battery terminals are protected to
prevent short circuits, unless the
wheelchair or mobility aid design provides an effective means of preventing
unintentional activation, and
(v) The battery is - 
(A) Securely attached to the wheelchair or mobility aid;
(B) Is removed and placed in a strong,
rigid packaging marked  - NONSPILLABLE BATTERY -  (unless fully enclosed in a rigid housing that is properly marked);

spillable battery, when carried as
checked baggage, provided - 
(i) Visual inspection including removal of the battery, where necessary,
reveals no obvious defects (however, removal of the battery from the housing
should be performed by qualified airline personnel only);
(ii) The battery is disconnected and
terminals are insulated to prevent
short circuits;
(iii) The pilot-in-command is advised,
either orally or in writing, prior to departure, as to the location of the battery aboard the aircraft; and
