Storage & Loading

2. GENERAL LOADING AND
SECURING REQUIREMENTS
When dangerous goods subject to the
requirements herein are loaded in an aircraft, the
operator including its handling agents must
protect the packages of dangerous goods being
damaged, including by the movement of
baggage, mail, stores or other cargo. Particular
attention must be paid for transport, the type of
aircraft on which they are to be carried and the
method required to load that aircraft, so that
accidental damage is not caused through
dragging or mishandling of the packages

3. M. Tayfour 3
Protection from Damage
• Operators must protect packages of
dangerous goods from being damaged.
Particular attention must be paid to the
handling of packages during their
preparation for transport, the type of
aircraft on which they are to be carried
and the method required to load that
aircraft, so that accidental damage is not
caused through dragging or mishandling
the packages

4. M. Tayfour 4
Inspection of Packages of Dangerous Goods
• Packages or over-packs must not be
loaded onto an aircraft or into a unit load
device unless they have been inspected
immediately prior to loading and found
free from visible leaks or damage.
• Before loading on an aircraft, unit load
devices must be inspected and found
free from any evidence of leakage or
damage that would cause it to be
unserviceable

Handling of Self-reactive
Substances and Organic Peroxides
• Packages and unit load devices
containing packages of self-reactive
substances of Division 4.1 and/or organic
peroxides of Division 5.2 must be
protected from direct sunlight and kept
away from all sources of heat and be
placed in adequately ventilated areas
during the course of loading, unloading
and storage.

8. M. Tayfour 8
Storage and Handling of Radioactive
Materials
• The principles used for the loading of radioactive
materials on passenger and cargo aircraft are
the same as those applied to the storage of
radioactive materials in the warehouse. It should
be noted that the transport index of any one
group of yellow label radioactive materials stored
together must not exceed 50. Individual
operators requirements must also be adhered to
at all times these may be found in the operators’
procedures manuals or dangerous goods
manual.

LOADING

10. M. Tayfour 10
Loading of Incompatible Dangerous Goods
Packages containing dangerous goods, which might
react dangerously with each other, must not be
stowed on an aircraft (or in a warehouse) next to
each other, or in any position that would allow
interaction between them in the event of a leakage.
To maintain acceptable segregation between
packages containing dangerous goods having
different hazards, the segregation requirements
shown in DGR Table 9.3.A (illustrated below) must
be observed. The segregation requirements apply
based on all hazard labels applied to the package,
irrespective of whether the hazard is the primary or
subsidiary risk.

11. M. Tayfour 11
Segregation of Packages

12. M. Tayfour 12
EITHER separating tie-
down
of the packages:
OR locating
ordinary
non-dangerous
cargo
packages between
incompatible
packages:
Segregation can be achieved by:

13. M. Tayfour 13
Loading on Cargo Aircraft
Packages bearing the “Cargo Aircraft Only” label must be loaded on a cargo
aircraft so that they are accessible (they can be seen, handled and, where size and
weight permit, separated from other cargo in flight). Hazard warning labels and the
Cargo Aircraft Only (CAO) label must be visible.

14. M. Tayfour 14
Stowage of Packages Containing Liquid
Dangerous Goods
Packages bearing the package orientation “This Way Up” label must
be loaded .

15. M. Tayfour 15
Stowage of Toxic and Infectious Substances
Packages having a Division 6.1 or a Division 6.2 label must
not be stowed in the same compartment with:
1. Animals;
2. Foodstuffs;
3. Feed; or
4. Other edible substances
intended for consumption by
humans or animals.

16. M. Tayfour 16
Loading and Stowage of Radioactive
Material
Radioactive material
in Categories I-White,
II-Yellow or III-Yellow
must not be loaded in
a compartment
occupied by
passengers or crew.

17. M. Tayfour 17
Package 1 = 5.5 TI
= needs 1.15 m separation from the top of the package
to the nearest inside surface of the floor of the aircraft
cabin. If the height of package 1 is 50 cm, then the cargo
hold must be at least 1.65 m high. i.e. 1.15 m + 50 cm
Package 2=4.2 TI
=needs 1.00 m separation from the top of the package
to the nearest inside surface of the floor of the aircraft
Example:

18. M. Tayfour 18
• Package 1 has the larger sum of TIs.
• Therefore, the minimum distance between Package 1 and Package 2
= 1.15 × 3
= 3.45 m

19. M. Tayfour 19
Loading of Magnetized Materials
Magnetized materials
must not be loaded in
such a position that
they will have a
significant effect on
the direct-reading
magnetic compasses
or on the master
compass detector
units of the aircraft.

20. M. Tayfour 20
Loading of Dry Ice (Carbon Dioxide, Solid)
Carbon dioxide,
solid (dry ice)
shipped by itself or
used as a
refrigerant for other
commodities may
be carried provided
that the operator
has made suitable
arrangements
dependent on the
aircraft type.

21. M. Tayfour 21
Loading of Live Animals with Dangerous
Goods
Live animals should not be loaded in
close proximity to cryogenic liquids or
dry ice. Live animals should be
stowed a level above packages
containing dry ice. They must be
separated from packages of Category
II-Yellow and III-Yellow radioactive
materials by at least 0.5 m (1 ft 8 in)
for journeys of 24 hours or less and
by at least 1 m (3 ft 4 in) for longer
journeys.

22. M. Tayfour 22
Loading of Battery-Powered Wheelchairs
To assist the handling of wheelchairs and mobility
aids with batteries, shows an example of a label
which may be used to assist in identifying whether
or not a wheelchair has had the battery removed.

23. M. Tayfour 23
UNIT LOAD DEVICES (ULD) CONTAINING
DANGEROUS GOODS
The tag must be removed from the ULD immediately after the
dangerous goods have been unloaded

24. M. Tayfour 24
6. Can the following packages of
dangerous goods be loaded next to each
other?
Package Compatible
(a) Division 6.1 and Class 3 YES / NO ………………

(c) Class 3 and Class 8 YES / NO ………………
(d) Division 5.1 and Class 3 YES / NO ………………

dangerous goods be loaded next to
the specific cargo? (segregation
Rules)
a) Division 6.1 and Live Animals
YES / NO
b) Class 7, Category II and Foodstuff

c) Carbon dioxide, solid and Hatching Eggs
YES / NO

26. 3. Using the segregation
chart/table for
incompatible dangerous
goods; Identify which
packages below must be
separated away from
packages containing
Division 5.1 – Oxidizer?
