ADR – The international carriage of dangerous goods by road
Carriage of accumulators pre-charged with Nitrogen
The European Agreement concerning the ADR was done at Geneva on 30 September 1957 under the auspices of the United Nations Economic Commission for Europe and it entered into force on 29 January 1968. The Agreement itself was amended by the Protocol amending article 14 (3) done at New York on 21 August 1975 that entered into force on 19 April 1985.
The ADR was restructured between 1992 and 2000 with the first version of the restructured annexes being published as ECE/TRANS/140 Volumes I and II on 1 July 2001. Corrections are now made every two years with a six-month provisional period between January and July where either version could be used. The latest version was published as ECE/TRANS/175 Volumes I and II on 1 January 2005.
The ADR was an international Regulation on 10 May 2004, there had been a change to the UK la on existing domestic regulations concerning the carriage of dangerous goods by road and rail and the ADR had been adopted throughout the UK and Europe in line with EC co-operation and harmonisation.
UN 1066 Nitrogen, compressed class 2: code 1A: labels 2.2 limited quantities LQ1: packing instructions P200: mixed packing provisions MP9: instructions (M)
UN 3164 Articles pressurised (pneumatic or hydraulic) containing non-flammable gases class 2: code 6A: labels 2.2: special provisions 283/594: limited quantities LQO: packing instructions P003: mixed packing provisions MP9
Class 1 = explosives and Class 2 = gasses, UN 3164 with Special provision 594 (ADR exempt) would apply in the same way as fire extinguishers under UN 104.
If UN 1066 was used this would mean Special Provision 283 would apply and ADR Regulations would need to be met.
