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

Note

The asterisks are replaced by the class number and compatibility code

Explosives

Substances and articles which are classified as explosives but which present no significant hazard

Note

The asterisk is replaced by the compatibility code

Explosives

Very insensitive substances which have a mass explosion hazard

Note

The asterisk is replaced by the compatibility code

Explosives

No hazard statement

Note

The asterisk is replaced by the compatibility code

Flammable gases

Gases which at 20 °C and a standard pressure of 101.3 kPa:

• are ignitable when in a mixture of 13 per cent or less by volume with air; or
• have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit.

Alternative sign

Non-flammable non-toxic gases

Gases which:

• are asphyxiant – gases which dilute or replace the oxygen normally in the atmosphere; or
• are oxidizing – gases which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does; or
• do not come under the other divisions;

Alternative sign

Toxic gases

Gases which:

• are known to be so toxic or corrosive to humans as to pose a hazard to health; or
• are presumed to be toxic or corrosive to humans because they have an LC₅₀ value equal to or less than 5000 ml/m³ (ppm).

Flammable liquids

Liquids which have a flash point of less than 60 °C and which are capable of sustaining combustion

Alternative sign

Flammable solids, self-reactive substances and solid desensitized explosives

Solids which, under conditions encountered in transport, are readily combustible or may cause or contribute to fire through friction; self-reactive substances which are liable to undergo a strongly exothermic reaction; solid desensitized explosives which may explode if not diluted sufficiently

Substances liable to spontaneous combustion

Substances which 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

Substances which in contact with water emit flammable gases

Substances which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities

Alternative sign

Oxidizing substances

Substances which, while in themselves not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material

Organic peroxides

Organic substances which contain the bivalent –O–O– structure and may be considered derivatives of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals

Alternative sign

Toxic substances

Substances with an LD₅₀ value ≤ 300 mg/kg (oral) or ≤ 1000 mg/kg (dermal) or an LC₅₀ value ≤ 4000 ml/m³ (inhalation of dusts or mists)

Corrosive substances

Substances which:

• cause full thickness destruction of intact skin tissue on exposure time of less than 4 hours; or
• exhibit a corrosion rate of more than 6.25 mm per year on either steel or aluminium surfaces at 55 °C
