The use of non-refillable cylinders. 2012

Non-refillable cylinders (NRC) are used to supply a range of gases and are common, for example, in the gas detection and safety markets. NRC’s are manufactured in many parts of the world. They are freely traded across international boundaries and in order to be put on the market within Europe, as dangerous goods, they are required to follow the regulations relating to the carriage of dangerous goods. It has come to the notice of the BCGA that a number of the traders of these products may be supplying cylinders and valves which do not conform to the appropriate regulations. The BCGA wish to draw attention to the shippers and users of these NRC products that it is their legal responsibility to ensure that all NRC’s are compliant with EC / EU directives and as such both the cylinders and valves have to be fully approved in accordance with these directives.
