Note: Referred to as “dangerous articles” in civil aviation management.
4 Classification of dangerous goods and packaging
4.1 Classification of dangerous goods
Dangerous goods are divided into nine classes according to the hazard or the predominant hazard they present. Some classes are further subdivided into divisions.
a) Class 1: Explosives
——Division 1.1: Substances and articles which have a mass explosion hazard;
——Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard;
——Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard;
——Division 1.4: Substances and articles which present no significant hazard;
——Division 1.5: Very insensitive substances which have a mass explosion hazard;
——Division 1.6: Extremely insensitive articles which do not have a mass explosion hazard.
b) Class 2: Gases
——Division 2.1: Flammable gases;
——Division 2.2: Non-flammable, non-toxic gases;
——Division 2.3: Toxic gases.
c) Class 3: Flammable liquids
d) Class 4: Flammable solids; substances liable to spontaneous combustion; substances which, in contact with water, emit flammable gases
——Division 4.1: Flammable solids, self-reactive substances, solid desensitized explosives and polymerizing substances;
——Division 4.2: Substances liable to spontaneous combustion;
——Division 4.3: Substances which, in contact with water, emit flammable gases.
e) Class 5: Oxidizing substances and organic peroxides
——Division 5.1: Oxidizing substances;
——Division 5.2: Organic peroxides.
f) Class 6: Toxic and infectious substances
——Division 6.1: Toxic substances;
——Division 6.2: Infectious substances.
g) Class 7: Radioactive material
h) Class 8: Corrosive substances
i) Class 9: Miscellaneous dangerous substances and articles, including environmentally hazardous substances
Note: The numerical order of the classes or divisions does not indicate the degree of hazard.
4.2 Classification of dangerous-goods packaging
For dangerous goods other than those of Class 1, Class 2, Class 7, Division 5.2 of Class 5, Division 6.2 of Class 6 and self-reactive substances of Division 4.1 of Class 4, the packaging is assigned to three packing groups according to the degree of danger they present:
a) Packing group I – substances presenting high danger;
b) Packing group II – substances presenting medium danger;
c) Packing group III – substances presenting low danger.
