We use oxy-acetylene cylinders for welding and we are trying to determine the inspection frequency.

The Transportation of Carriage of Dangerous Goods and Use of Transportable Pressure Receptacles Regulations 2004 and the HSE Guidance on cylinders sends us in a loop between the HSE and the DoT.

How often should gas cylinders in use be inspected,a nd does this include the gauges.

... the British Compressed Gases Association may be able to help also, but they may charge for advice

Don’t know if this link is of any use, but try

www.hse.gov.uk/foi/inter...fod/oc/300-399/307_5.pdf

have not had much dealing with oxy-acetylene cylinders but have some experience of other types of gas cylinders and on these the test date is usualy stamped on the neck or collar of the cylinder.

I don’t think the regulations cover the guages – if part of a fixed system then may be subject to the pressure systems safety regulatins 2000, but I suspect you are refering to the mobile systems I have seen in garages etc. In these cases I belive you should apply the Provosion and Use of Work equipment Regulations and hence have a servicing/maitance regime. I would ask the guage manufacture for advice.

Good Luck.

The pressure systems safety regulations 2000 is not for fixed systems - the criteria for the level and type of inspection is based on the pressure.volume product.

You are quite correct and my apologies for a quick response that could have been misleading. What I meant was the regulations do not usually apply to portable cylinders that are filled elsewhere (such as those used in SCUBA) as they are covered by different regulations.

The criteria is for them to be within test when they are filled. The cylinders will be inspected at every fill by the gas company and re-tested every 10 years, for example, for Oxygen, Nitrogen, Argon, etc. There is usually nothing regarding test status for the user to be concerned about.

There will be a date stamp on the shoulder.

These cylinders can still be safely used if they go out of test when on-site as the view is taken that the pressure in the cylinder will be reducing all the time as the gas is used.
