Classification and labelling of dangerous goods – ADR – IMO

1 – Explosive substances and objects
Applies to explosive substances and objects covered by sections 1.1, 1.2 and 1.3. Conventional sign of a bomb exploding
Note: ** Division indication
* Compatibility group indication

1.4 – Explosive substances and objects
Substances and articles that present a minor explosion hazard in the event of ignition or priming during transport.

1.5 – Explosive substances and objects
Substances and articles that present a minor explosion hazard in the event of ignition or priming during transport.

1.6 – Explosive substances and objects
Extremely insensitive articles which do not have a mass explosion hazard

2.1 – Flammable gas
Applied to flammable gases in a mixture of up to 13% with air

2.2 – Non-flammable non-toxic gas
Applied to materials that at 50°C have a vapour pressure greater than 300 kPa (3 bar) or are in a fully gaseous state at 20°C, at a standardised pressure of 101.3 kPa

2.3 – Toxic gas
Known to be toxic or corrosive to humans to the point of posing a danger to their health. They are assumed to be toxic or corrosive to humans because their CL50 for acute toxicity is less than or equal to 5,000 ml/m3

Which have a maximum flash point of 61°C.

4.1 – Solid flammable substances
That can be ignited by rubbing, self-reactive materials, are thermally unstable materials and desensitized explosive materials, are materials that have been moistened with alcohol or water to nullify their explosive properties

4.2 – Spontaneously flammable substances
They include pyrophoric matter and materials and objects that undergo spontaneous heating

4.3 – Matter that, when in contact with water, emit flammable gases
They are materials that, by reaction with water, give off flammable gases that can form explosive mixtures with air.

5.1 – Oxidisers
These are substances that, since they give off oxygen, cause or promote the combustion of other materials

5.2 – Organic peroxides
These are subject to exothermic decomposition at normal or high temperatures

6.1 – Toxic materials
These are substances that can harm human health or cause death by inhalation, skin absorption, or ingestion

6.2 – Infectious substances
These are substances which are known or are reasonably expected to contain pathogens

7.A – Radioactive materials, white category I
These are substances that emit particles and radiation capable of causing damage to cells
Maximum radiation intensity at any point of the external surface does not exceed 0.005 mSv/h.

7.B – Radioactive matter, yellow category II
Maximum radiation intensity at any point on the external surface, more than 0.005 mSv/h but no more than 0.5 mSv/h.

7.C – Radioactive matter, yellow category III
Maximum radiation intensity at any point on the external surface, more than 0.5 mSv/h but no more than 2 mSv/h.

7.E – Fissile materials
Maximum radiation intensity at any point on the external surface. Fissile matter means uranium 233, uranium 235, plutonium 239 or plutonium 241, or any combination of these radionuclides.

These are substances that, through their chemical action, damage the skin epithelial tissue and mucous membranes when they come into contact with them, or that, in the event of leakage, may cause damage to other goods or means of transport or destroy them

9 – Miscellaneous dangerous substances and articles
This includes substances and articles that, during transport, pose a different danger from those contemplated by the other classes

9.A – Miscellaneous dangerous substances and articles, lithium batteries
This includes substances and articles that, during transport, pose a different danger from those contemplated by the other classes
