ADR ( treaty ) - wikipedia ADR ( treaty ) ADR ( formally, the European Agreement concerning the International Carriage of Dangerous Goods by Road ( ADR ) ) is a 1957 United Nations treaty that governs transnational transport of hazardous materials. `` ADR '' is derived from the French name for the treaty : Accord européen relatif au transport international des marchandises Dangereuses par Route ). Concluded in Geneva on 30 September 1957 under the aegis of the United Nations Economic Commission for Europe, it entered into force on 29 January 1968. The agreement was modified ( article 14, paragraph 3 ) in New York City on 21 August 1975, though these changes only took effect on 19 April 1985. A new amended ADR 2011 entered into force on 1 January 2011. Annexes A and B have been regularly amended and updated since the entry into force of ADR. Consequently, to the amendments for entry into force on 1 January 2015 ( until June 2017 ), a revised consolidated version has been published as document ECE / TRANS / 242, Vol. I and II. A further revision applies from 1 January 2017 As of 2016, 49 states are party to ADR. Contents 1 Contents 2 Hazard classes 3 Tunnel classifications 4 ADR pictograms 5 See also 6 References 7 External links Contents The agreement itself is brief and simple, and its most important article is article 2. This article states that with the exception of certain exceptionally dangerous materials, hazardous materials may in general be transported internationally in wheeled vehicles, provided that two sets of conditions be met : Annex A regulates the merchandise involved, notably their packaging and labels. Annex B regulates the construction, equipment, and use of vehicles for the transport of hazardous materials. The appendices consist of nine chapters, with the following contents General provisions : terminology, general requirements Classification : classification of dangerous goods Dangerous Goods List sorted by UN number, with references to specific requirements set in chapters 3 to 9 ; special provisions and exemptions related to dangerous goods packed in limited quantities Packaging and tank provisions Consignment procedures, labeling, and marking of containers and vehicles. Construction and testing of packagings, intermediate bulk containers ( IBCs ), large packagings, and tanks Conditions of carriage, loading, unloading, and handling Vehicle crews, equipment, operation, and documentation Construction and approval of vehicles Hazard classes The classes of dangerous goods according to ADR are the following : Class 1 Explosive substances and articles Class 2 Gases, including compressed, liquified, and dissolved under pressure gases and vapors Flammable gases ( e.g. butane, propane, acetylene ) Non-flammable and non-toxic, likely to cause asphyxiation ( e.g. nitrogen, CO ) or oxidisers ( e.g. oxygen ) Toxic ( e.g. Chlorine, Phosgene ) Class 3 Flammable liquids Class 4.1 Flammable solids, self - reactive substances, and solid desensitized explosives Class 4.2 Substances liable to spontaneous combustion Class 4.3 Substances which, in contact with water, emit flammable gases Class 5.1 Oxidizing substances Class 5.2 Organic peroxides Class 6.1 Toxic substances Class 6.2 Infectious substances Class 7 Radioactive material Class 8 Corrosive substances Class 9 Miscellaneous dangerous substances and articles Each entry in the different classes has been assigned a 4 digit UN number. It is not usually possible to deduce the hazard class ( es ) of a substance from its UN number : they have to be looked up in a table. An exception to this are Class 1 substances whose UN number will always begin with a 0. See List of UN numbers Tunnel classifications The ADR Secretariat has defined a classification system for major tunnels in Europe. `` The categorization ( is ) based on the assumption that in tunnels there are three major dangers ( that ) may cause numerous victims or serious damage to the tunnel structure. '' It is the responsibility of each national authority to categorize its tunnels accordingly. The classes ranges from A ( least restrictive ), to E ( most restrictive ). As of 2010, in the United Kingdom for example, the least restrictive was the tunnel carrying the A299 to the Port of Ramsgate, while the most restrictive were several tunnels in East London, including the Limehouse Link Tunnel, the Rotherhithe Tunnel, the Blackwall Tunnel and the East India Dock Link Tunnel.
