Dangerous goods and regulations- Questions and
Answers
Training Correct Ans-Operators must establish and maintain training programs that cover
the regulatory requirements depending on the staff's duties. Cabin Crew will not be trained
the same way as Cargo warehouse staff or those loading Dangerous Goods on an aircraft. Staff
receives training tailored to their functions, but each staff member must receive training and
be familiar with Dangerous Goods. This training includes familiarization with the hazards and
risks involving Dangerous Goods and how to respond to incidents involving Dangerous Goods.
The cabin crew should also be familiar with how Dangerous Goods may be carried as baggage.
Dangerous Goods training must be approved by the Authority and each staff member must
receive recurrent training every two years.
Even though an operator may only transport passengers, not cargo, their staff must be trained
in Dangerous Goods as passengers often bring Dangerous Goods in their baggage
Classification Correct Ans-Dangerous Goods are classified based on hazard type. There are
nine hazard classes and several sub-divisions. Articles and substances may belong to more
than one hazard class, where the main hazard will be the main classification.
Class 1 - Explosives Correct Ans-Has several divisions based on explosion hazard and
sensitivity, most forbidden for air transport. Some types of explosives are allowed as cargo.
The types of explosives we are likely to find in air transport belong to Division 1.4 as those
include emergency flares and ammunition for weapons.
Class 2 - Gases Correct Ans-Gases have three divisions based on their properties.
2.1 - Flammable Gas: gas that is flammable such as propane, hydrogen, or hair spray
, Dangerous goods and regulations- Questions and
Answers
2.2 - Non-Flammable, compressed gas: gas which in itself is not dangerous, but is dangerous
because it is under pressure. If the pressure valve does not work as it should, the gas will
propel the container and can do damage to the aircraft or explode if there is fire. They may
also dilute or replace the oxygen normally in the atmosphere or provide oxygen which may
contribute to an active fire or explosion. CO2 and Oxygen tanks.
2.3 - Toxic Gas: gas that has toxic effects when inhaled, such as tear gas.
Class 3 - Flammable liquids Correct Ans-Liquids that are flammable themselves or emit
flammable gases at the temperature which they may encounter in the transport. These
include paint, alcohol, acetone and petrol
Class 4 - Flammable solids Correct Ans-Flammable solids have three divisions based on
their properties.
4.1 - Flammable solids: these are solids that are flammable or readily combustible, such as the
head of matches or Sulphur. These solids may also contribute to fire through friction or easily
ignited by brief contact with an ignition source.
4.2 - Substances liable to spontaneous combustion: are solids that combust spontaneously in
air, such as phosphorus. These are liable to spontaneous heating under normal conditions
encountered in transport, or to heating up in contact with air and being then liable to catch
fire.
