unit load devices must be separated by
other cargo with a minimum separa-
tion of 2 m (6.5 feet). When not loaded
in unit load devices, Division 1.4B and
Division 1.3 explosives must be loaded
into different, non-adjacent loading po-
sitions and separated by other cargo
with a minimum separation of 2 m (6.5
feet).

tion of a row and column means that
other than explosives of Division 1.4,
Compatibility Group S, explosives may
not be stowed together with that class.

(6) Packages containing hazardous

materials with multiple hazards in the
class or divisions, which require seg-
regation in accordance with the Seg-
regation Table, need not be segregated

with a package of special fireworks or
railway torpedoes.

§ 175.88

Inspection, orientation and se-

curing packages of hazardous mate-
rials.

(a) A unit load device may not be

loaded on an aircraft unless the device
has been inspected and found to be free
from any evidence of leakage from, or
damage to, any package containing
hazardous materials.

(b) A package containing hazardous

materials marked ‘‘THIS SIDE UP’’ or
‘‘THIS END UP’’, or with arrows to in-
dicate the proper orientation of the
package, must be stored and loaded
aboard an aircraft in accordance with
such markings. A package without ori-
entation markings containing liquid
hazardous materials must be stored
and loaded with top closure facing up-
ward.

materials must be secured in an air-
craft in a manner that will prevent any
shifting or any change in the orienta-
tion of the packages. Packages con-
taining Class 7 (radioactive) materials
must be secured in a manner that en-
sures that the separation requirements

of §§ 175.701 and 175.702 will be main-
tained at all times during flight.

§ 175.90

Damaged shipments.

(a) Packages or overpacks containing

hazardous materials must be inspected
for damage or leakage after being un-
loaded from an aircraft. When pack-
ages or overpacks containing haz-
ardous materials have been transported
in a unit load device, the area where
the unit load device was stowed must
be inspected for evidence of leakage or
contamination immediately upon re-
moval of the unit load device from the
aircraft, and the packages or overpacks
must be inspected for evidence of dam-
age or leakage when the unit load de-
vice is unloaded. In the event of leak-
age or suspected leakage, the compart-
ment in which the package, overpack,
or unit load device was carried must be
inspected for contamination and decon-
taminated, if applicable.

(b) Except as provided in § 175.700, the

operator of an aircraft must remove
from the aircraft any package, baggage
or cargo that appears to be leaking or
contaminated by a hazardous material.
In the case of a package, baggage or
cargo that appears to be leaking, the
operator must ensure that other pack-
ages, baggage or cargo in the same
shipment are in proper condition for
transport aboard the aircraft and that
no other package, baggage or cargo has
been contaminated or is leaking. If an
operator becomes aware that a pack-
age, baggage or cargo not identified as
containing a hazardous material has
been contaminated, or the operator has
cause to believe that a hazardous mate-
rial may be the cause of the contami-
nation, the operator must take reason-
able steps to identify the nature and
source of contamination before pro-
ceeding with the loading of the con-
taminated baggage or cargo. If the con-
taminating substance is found or sus-
pected to be hazardous material, the
operator must isolate the package,
baggage or cargo and take appropriate
steps to eliminate any identified haz-
ard before continuing the transpor-
tation of the item by aircraft.
