International Carriage Of Dangerous Goods By Road

Concerning the International Carriage of Dangerous Goods by Road (ADR), regulation is via the European Agreement.

ADR sets out the requirements for the classification, packaging, labelling and certification of dangerous goods. It also includes specific vehicle and tank requirements and other operational requirements. The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (as amended) apply ADR in Great Britain - England, Wales and Scotland.

International Carriage Of Dangerous Goods By Air

The International Civil Aviation Organization's (ICAO) Technical Instructions are a globally concurred set of provisions representing the requirements for transporting hazardous products by air freight.

The International Air Transport Association (IATA) distributes the Dangerous Goods Regulations as per the ICAO technical instructions.

Transport Emergency Cards (Instructions In Writing)

Any product that is classified with a UN number, Transport Emergency Cards (Tremcards) are automatically produced for. Emergency Cards are fully compliant with current legislation and can be printed any of the languages listed in the ADR regulations.

Companies who ship hazardous goods throughout Europe, need to provide the driver with Transport Emergency Cards (Instructions in Writing). These emergency instructions must be written in the language the driver can understand and those countries through which the load will travel.

For all modes of transport (sea, air, rail, road and inland waterways) the classification (grouping) of dangerous goods, by type of risk involved, has been drawn up by the UNITED NATIONS Committee of Experts on the Transport of Dangerous Goods (UN).










Packing Group

Packing groups determine the level of protective packaging required for Dangerous Goods during transport.

Group I:  Great danger, most protective packaging required. Various combinations of different classes of dangerous goods on the same vehicle or in the same mode of transport are forbidden if any of the goods fall under Group I.

Group II: Medium danger.

Group III: Least danger among regulated goods, and least protective packaging within transport.

UN Number

UN numbers are four digit numbers that identify hazardous substances, and items (such as explosives, flammable liquids, toxic substances, etc) for international transport. Various hazardous substances have their own UN numbers (e.g. acrylamide has UN2074), while some groups of chemicals or products with similar properties receive a common UN number (e.g. flammable liquids, not otherwise specified, have UN1993).

A chemical in its solid state may receive a different UN number than the liquid phase if their hazardous properties differ significantly; substances with different levels of purity (or concentration in solution) may also receive different UN numbers.

UN numbers range from UN0001 to about UN3506 and are assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods. They are published as part of their Recommendations on the Transport of Dangerous Goods, also known as the Orange Book. These recommendations are adopted by the regulatory organization responsible for the different modes of transport.

There is no UN number allocated to non-hazardous substances. These will simply not have a UN number.

Dangerous Goods Safety Adviser

The shipper must have a dangerous goods safety adviser (DGSA) if they transport dangerous goods, unless:

- The shipper only arranges it occasionally (breakdown recovery vehicles)
- The shipper is only receiving the dangerous goods (the shipper is the ‘consignee’)
- The material is only classed as ‘limited quantities’
- The shipper is only transporting the dangerous goods a very short distance by road or between buildings on an industrial estate
- The shipper is using private vehicles

A DGSA must receive training and qualification - further assistance is available from the Department for Transport website.

For any dangerous goods being transporting internationally, a DGSA should be appointed.

Appointing A Dangerous Goods Safety Adviser

The shipper can either have a member of staff trained as a dangerous goods safety adviser or alternatively use a company that specialises in providing dangerous goods safety advice.
