  • Restrictions on Dangerous Goods

Dangerous Goods are articles or substances which are capable of posing a hazard to health, safety, property or the environment when transported by air. The International Civil Aviation Organization (ICAO) classified dangerous goods in 9 classes, which are:

Class 1 Explosives
Class 2 Gases
Class 3 Flammable liquids
Class 4 Flammable solids; substances liable to spontaneous combustion; substances which, in contact with water, emit flammable gases
Class 5 Oxidizing substances and organic peroxides
Class 6 Toxic and infectious substances
Class 7 Radioactive material
Class 8 Corrosive substances
Class 9 Miscellaneous dangerous substances and articles

As a passenger, it is an offence under the Air Navigation (Hong Kong) Order 1995 (Cap.448C) to take dangerous goods (except for certain dangerous goods in very small quantity and in special condition) on board an aircraft. The law restricts the type and quantity of dangerous goods allowed to be carried by passengers, because they can be a danger to you and the aircraft in flight due to temperature and pressure difference.

If PEDs containing lithium batteries (such as laptop / tablet computer) are carried in checked baggage:

To ensure aviation safety, passengers are reminded not to transport on aircraft any lithium batteries or devices containing such batteries, which are damaged, identified to be defective, or recalled by manufacturer for safety reasons due to potential fire hazard.
