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.

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.

Carriage By Rail

The carriage of dangerous goods by rail is governed by Appendix C of the Convention Covering International Carriage by Rail - International Carriage of Dangerous Goods by Rail. The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (as amended) apply in Great Britain.

Dangerous Goods Note

When dangerous goods are transported, the consignment must be accompanied by a document that contains information declaring the nature of the dangers of the goods. The DGN (Dangerous Goods Note) enables the shipper to complete one standard document for all consignments irrespective of port or inland depot. By doing so, it provides the receiving authority with complete, accurate and timely information as well as providing all those with an interest in the consignment with adequate information at each stage of the transport movement. The greatest benefit of using the DGN is that receiving authorities have clear and precise information on the way the goods should be handled.

Exporters should NOT use this box for the purpose of quoting just the commercial reference of the consignment (see Box 4 below). This box should NOT be used for declaring the Master UCR (MUCR) - see Box 12 below - or consignments in FREE CIRCULATION moving solely within the EU.

g. Additional Information - It is necessary to provide supplementary information in
certain circumstances These are detailed in Chapter 5.4 of the IMDG Code, ADR
and RID and also shown on the reverse of the DGN. Particular attention should be
paid to the following:

• Requirements for Specific Classes, including infectious and radioactive material.
• Salvage Packaging, Waste, Elevated Temperatures.
• Empty Uncleaned Packagings and Tanks. There are some differences between the road, rail and sea regulations.
• For Sea only - Limited Quantities, Marine Pollutants, and Flashpoint.
• For Road or Rail only - Exemption Limits, Tanks, IBCs, Piggyback transport by rail.

h. Customs - Where a consignment forms part of a consolidation or groupage
movement this box should also be used to declare the Master UCR (MUCR). The
consolidator or groupage operator should construct the MUCR in accordance with
the format prescribed by HM Revenue & Customs , including the use of alpha,
numeric characters and spaces, hypens and forward slashes - see HM Revenue &
Customs Tariff and Public Notice No. 276.

The consolidator or groupage operator should normally add the MUCR to a

date (where and when signed), signature of person responsible for the packing/loading
of the dangerous goods into the container/vehicle.

NB: The container/vehicle packing certificate and declaration serves a separate function
to the dangerous goods declaration, and the two are very often signed by different
people. However, for the sake of convenience the two declarations are included in the
same document. The consignor (exporter) of the goods is responsible for signing the
dangerous goods declaration (box 17), but the declaration under the container/vehicle
packing certificate (box 15) must be signed by whoever is responsible for
packing/loading the dangerous goods into the container/vehicle. It is clearly
inappropriate for the consignor to sign the packing certificate (box 15), if the
packing/loading of the container/vehicle is undertaken elsewhere - e.g. at a groupage or
consolidation depot, or at an outside warehouse.

16. Container identification number/vehicle registration number

Goods Declaration).

Classification Of Dangerous Goods & Labels

The International Maritime Dangerous Goods (IMDG) Code was created as a uniform international code for the transportation of dangerous goods by sea covering packing, container traffic and stowage, with reference to the segregation of incompatible substances.

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 container 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.

Contact the Department for Transport by email for advice on appointing a DGSA adviser.
