§ 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. 

(c) No person may place aboard an 

aircraft a package, baggage or cargo 
that is contaminated with a hazardous 
material or appears to be leaking. 

(d) If a package containing a mate-

rial in Division 6.2 (infectious sub-
stance) is found to be damaged or leak-
ing, the person finding the package 
must: 

(1) Avoid handling the package or 

keep handling to a minimum; 

(2) Inspect packages adjacent to the 

leaking package for contamination and 
withhold from further transportation 
any contaminated packages until it is 
ascertained that they can be safely 
transported; 

(3) Comply with the reporting re-

quirement of §§ 171.15 and 175.31 of this 
subchapter; and 

(4) Notify the consignor or consignee.
