Cylinders for Gases

LPG Cylinders

Steel cylinders used for LPG must be periodically inspected and tested to ensure they remain safe and fit for purpose.  Normally, the maximum interval between inspections is 10 years and this is set by the International Agreement for the Carriage of Dangerous Goods by Road (ADR).  Since 2011, ADR has allowed the competent authority to authorise the interval to be extended to 15 years providing certain conditions are met.  Cylinders so authorised may be marked P15Y. A transitional provision permits previous arrangements to continue until 1st January 2015.

Our Dangerous Goods Office operates a scheme on behalf of the competent authority to authorise extended inspection intervals for LPG cylinders which are used exclusively in Great Britain.  The VCA scheme is available now to GB companies wishing to comply with the provisions of ADR Packing Instruction P200 (10) in advance of the end of the transitional period. This will be the only means by which inspection intervals may be extended for new steel cylinders placed into service from the 1st January 2015.
