The document outlines the training course for flight crew and operations officers on dangerous goods regulations, with a focus on safety and legal compliance. It covers the identification, handling, documentation, and emergency response for dangerous goods, detailing their classifications, packaging, labeling, and the responsibilities of shippers and operators. The regulations emphasize the importance of proper training and adherence to guidelines to ensure safe transport of hazardous materials in aviation.

• To provide Flight crew / Ops Officer the competencies
necessary for recognising undeclared dangerous goods
from visual indications;
• Verifying that dangerous goods cargo are loaded as
shown on the NOTOC and cargo manifest,
• There is no evidence of damage or leakage and that
dangerous goods are secured to prevent movement
during flight;
• Report dangerous goods incidents, accidents, and

GENERAL PHILOSOPHY
Dangerous Goods can be transported safely as long as certain
principles are followed
• DG correctly classified
• Ensure prohibited items are not shipped by air
• Ensure correct packaging and labeling used
• All staff correctly trained
• DG are correctly declared
• The Captain is advised of the location of any DG on board
• All categories of staff check for hidden hazards

8. DEFINITION OF DANGEROUS GOODS
Dangerous Goods are articles or
substances which are capable of
posing a hazard to health, safety,
property or the environment, and which
are shown in the list of Dangerous
Goods in the Dangerous Goods
Regulations or which are classified
according to these Regulations.

• Dangerous Goods are divided into 9 classes
– The first 8 classes reflect the type of
Hazard.
– Class 9 contains articles which do not fit the
other 8 classes or have multiples hazards
• In some cases these classes are further
divided into sub-divisions

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 loading,

108. 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:
109

109. 110
● Package 1 has the larger sum of TIs.
● Therefore, the minimum distance between Package 1 and Package 2
= 1.15 × 3
= 3.45 m

Loading of Magnetized Materials
Magnetized materials must not
be loaded in such a position

Loading of Dry Ice (Carbon Dioxide, Solid)
Carbon dioxide, solid (dry ice)
shipped by itself or used as a

commodities may be carried
provided that the operator has
made suitable arrangements
dependent on the aircraft type.

112. Loading of Live Animals with DG
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.
