compartment or its equivalent.
(e) A cylinder containing medical-use
compressed oxygen, owned or leased by
an aircraft operator or offered for
transportation by a passenger needing
it for personal medical use at destina-
tion, may be carried in the cabin of a
passenger-carrying aircraft in accord-
ance with the following provisions:
(1) No more than six cylinders be-
longing to the aircraft operator and, in
addition, no more than one cylinder
per passenger needing the oxygen at
destination, may be transported in the

inder may not exceed 1,000 L (34 cubic
feet);
(3) Each cylinder must conform to

tion 300 for a Category I Shipping Con-
tainer; or
(ii) A metal, plastic or wood outer
packaging that conforms to a UN
standard at the Packing Group I or II
performance level.
(4) The aircraft operator shall se-
curely stow the cylinder in its over-
pack or outer packaging in the cabin of
the aircraft and shall notify the pilot-
in-command as specified in § 175.33 of
this part; and
(5) Shipments under this paragraph
(e) are not subject to—

§ 175.630
Special requirements for Di-
vision 6.1 (poisonous) material and
Division 6.2 (infectious substances)
materials.
(a) [Reserved]
(b) No person may operate an aircraft
that has been used to transport any
package required to bear a POISON or
POISON INHALATION HAZARD label
unless, upon removal of such package,
the area in the aircraft in which it was
carried is visually inspected for evi-
dence of leakage, spillage, or other
contamination. All contamination dis-
covered must be either isolated or re-
moved from the aircraft.
(c) When unloaded from the aircraft,
each package, overpack, pallet, or unit
load device containing a Division 6.2
material must be inspected for signs of
leakage. If evidence of leakage is
found, the cargo compartment in which
the package, overpack, or unit load de-
vice was transported must be dis-
infected. Disinfection may be by any
means that will make the material re-
leased ineffective at transmitting dis-
ease.

§ 175.700
Special limitations and re-
quirements for Class 7 materials.
(a) Except as provided in §§ 173.4a,
173.422 and 173.423 of this subchapter,
no person may carry any Class 7 mate-
rials aboard a passenger-carrying air-
craft unless that material is intended
for use in, or incident to research (See
§ 171.8 of this subchapter), medical diag-
nosis or treatment. Regardless of its
intended use, no person may carry a
Type B(M) package aboard a passenger-
carrying aircraft, a vented Type B(M)
package aboard any aircraft, or a liq-
uid pyrophoric Class 7 material aboard
any aircraft.
(b)
Limits for transport index and criti-
cality safety index.
A person may carry
the following Class 7 (radioactive) ma-
terials aboard an aircraft only when—
(1) On a passenger-carrying aircraft—
(i) Each single package on the air-
craft has a transport index no greater
than 3.0;
(ii) The combined transport index
and the combined criticality index of
871
Pipeline and Haz. Matls. Safety Admin., DOT
§ 175.701
all the packages on the aircraft are
each no greater than 50.
(2) On a cargo aircraft—
(i) Each single package on the air-
craft has a transport index no greater
than 10.0.
(ii) The combined transport index of
all the packages on the aircraft is no
greater than 200, and the combined
criticality index of all the packages on
the aircraft is no greater than—
(A) 50 on a non-exclusive use cargo
aircraft, or
(B) 100 on an aircraft assigned for the
exclusive use of the shipper [offeror]
for the specific shipment of fissile
Class 7 material. Instructions for the
exclusive use must be developed by the
shipper [offeror] and carrier, and the
instructions must accompany the ship-
ping papers.
(3) The combined transport index and
combined criticality index are deter-
mined by adding together the transport
index and criticality index numbers,
respectively, shown on the labels of the
individual packages.
(c) No person may carry in a pas-
senger-carrying aircraft any package
required to be labeled RADIOACTIVE
YELLOW–II or RADIOACTIVE YEL-
LOW–III label unless the package is
carried on the floor of the cargo com-
partment or freight container.

minimum separation distances that
must be maintained in a passenger-car-
rying aircraft between Class 7 (radio-
active) materials labeled RADIO-

(b) When transported aboard pas-
senger-carrying aircraft packages,
overpacks or freight containers labeled
Radioactive Yellow–II or Radioactive
Yellow–III must be separated from live
animals by a distance of at least 0.5 m
(20 inches) for journeys not exceeding
24 hours, and by a distance of at least
1.0 m (39 inches) for journeys longer
than 24 hours.
(c) Except as provided in paragraph
(d) of this section, the minimum sepa-
ration distances prescribed in para-
graphs (a) and (b) of this section are de-
termined by measuring the shortest
distance between the surfaces of the
Class 7 (radioactive) materials package
and the surfaces bounding the space oc-
cupied by passengers or animals. If
more than one package of Class 7 (ra-
dioactive) materials is placed in a pas-
senger-carrying aircraft, the minimum
separation distance for these packages
shall be determined in accordance with
paragraphs (a) and (b) of this section
on the basis of the sum of the transport
index numbers of the individual pack-
ages or overpacks.
(d)
Predesignated areas.
A package la-
beled RADIOACTIVE YELLOW–II or
RADIOACTIVE YELLOW–III may be
carried in a passenger-carrying aircraft
in accordance with a system of
predesignated areas established by the
aircraft operator. Each aircraft oper-
ator that elects to use a system of
predesignated areas shall submit a de-
tailed description of the proposed sys-
tem to the Associate Administrator for
approval prior to implementation of
the system. A proposed system of
predesignated areas is approved if the
