,1. A shipment of lithium ion batteries (UN3480, PI965) is being prepared for air
transport. The batteries exceed 20 Wh each but are packed in a strong outer
packaging with no more than 4 cells per package. Which of the following additional
requirements must be met?
A. The package must be marked with the lithium battery mark and a Class 9 hazard label.
B. The package must bear the Class 9 hazard label only if the net weight exceeds 5 kg.
C. The package must be accompanied by a Shipper's Declaration for Dangerous Goods.
D. The package must be marked with the lithium battery mark and the words 'OVER PACK'
if overpack is used.
Answer: A. The package must be marked with the lithium battery mark and a
Class 9 hazard label.
For UN3480 lithium ion batteries packed under PI965 Section IA or IB, the package
must display both the lithium battery mark and the Class 9 hazard label. Option B is
incorrect because the Class 9 label is required regardless of weight. Option C is not
always required for Section II shipments. Option D addresses overpack marking but is
not the primary requirement.
2. During pre-loading inspection of a consignment containing UN1263, Paint (Class
3, PG II), you notice that the outer packaging shows no orientation labels, but the
inner packagings are glass bottles containing flammable liquid. Which regulation is
violated?
A. No violation if the net quantity per inner packaging is less than 1 L.
B. Orientation labels are not required for Class 3 liquids if the outer packaging is fiberboard.
C. Orientation labels are required for combination packagings containing liquid dangerous
goods.
D. Orientation labels are only required if the package is over 30 kg gross weight.
Answer: C. Orientation labels are required for combination packagings containing
liquid dangerous goods.
According to IATA DGR 7.2.4.2, orientation labels are required on two opposite sides of
packages containing liquid dangerous goods in combination packagings. The absence
constitutes a violation. Options A, B, and D are incorrect as orientation labels are
mandatory regardless of quantity, material, or weight for liquids.

,3. A consignment of UN3082, Environmentally hazardous substance, liquid, n.o.s.
(Class 9, PG III) is to be shipped by air. Which of the following statements about the
environmental hazard mark is correct?
A. The environmental hazard mark is not required for air transport if the substance is in a
quantity less than 5 L.
B. The environmental hazard mark must be displayed on all packages containing UN3082,
regardless of quantity.
C. The environmental hazard mark is only required when the substance is transported in bulk
containers.
D. The environmental hazard mark is optional if the Class 9 hazard label is already applied.
Answer: B. The environmental hazard mark must be displayed on all packages
containing UN3082, regardless of quantity.
IATA DGR 7.1.6.3.3 requires the environmental hazard mark on all packages
containing environmentally hazardous substances (UN3077, UN3082) regardless of
quantity. Option A is incorrect as there is no quantity exemption. Option C is incorrect
because it applies to all packages. Option D is incorrect because the mark is separate
from the hazard label.
4. A shipper declares a substance as UN1993, Flammable liquid, n.o.s. (Class 3, PG
II). The flash point is 23°C and the boiling point is 40°C. Which packing group is
correct?
A. PG I
B. PG II
C. PG III
D. Not classified as dangerous goods
Answer: B. PG II
For flammable liquids, PG II applies to liquids with flash point <23°C and initial
boiling point >35°C. Here flash point 23°C (below 23°C threshold) and boiling point
40°C (above 35°C) meet PG II criteria. PG I requires boiling point 35°C. PG III
requires flash point 23°C and 60°C. Thus PG II is correct.

, 5. Which of the following combinations of dangerous goods is forbidden to be loaded
in the same cargo compartment of a passenger aircraft?
A. UN1203, Gasoline (Class 3) and UN1263, Paint (Class 3)
B. UN1040, Ethylene oxide (Class 2.3) and UN1016, Carbon monoxide (Class 2.3)
C. UN1744, Bromine (Class 8) and UN1805, Phosphoric acid (Class 8)
D. UN1381, Phosphorus, white (Class 4.2) and UN1350, Sulfur (Class 4.1)
Answer: B. UN1040, Ethylene oxide (Class 2.3) and UN1016, Carbon monoxide
(Class 2.3)
Ethylene oxide (UN1040) is forbidden on passenger aircraft per IATA DGR Table 2.3A.
Carbon monoxide (UN1016) is also forbidden. Therefore, both are prohibited, but the
question asks about forbidden combinations; however, the key point is that both are
individually forbidden. Option B is the only one where both substances are forbidden
on passenger aircraft, making the combination impossible. Options A, C, and D involve
substances permitted on passenger aircraft with restrictions.
6. A package containing UN2811, Toxic solid, organic, n.o.s. (Class 6.1, PG I) is
found to have a small leak during loading. According to IATA DGR, which of the
following actions is required?
A. Place the package in a polyethylene bag and seal it, then load it on the aircraft.
B. Remove the package from the aircraft immediately and notify the shipper.
C. Overpack the leaking package in a UN-specification overpack and continue loading.
D. No action is required if the leak is minor and the substance is not infectious.
Answer: B. Remove the package from the aircraft immediately and notify the
shipper.
IATA DGR 9.3.2 states that any package found leaking must be removed from the
aircraft and the shipper notified. Option A is incorrect because leaking packages cannot
be repaired or repacked without authorization. Option C is incorrect because
overpacking a leaking package is not permitted. Option D is incorrect because any leak
requires action.
