BS EN 1968:2002, British Standard for Transportable gas cylinders – Periodic inspection and testing of seamless steel gas cylinders
BS EN 1802:2002, British Standard for Transportable gas cylinders – Periodic inspection and testing of seamless aluminium alloy gas cylinders
BS EN 1803:2002, British Standard for Transportable gas cylinders – Periodic inspection and testing of welded carbon steel gas cylinders, all state, in clause 3, that:
• In the case of cylinders used for emergency purposes (e.g. fire extinguishers, breathing apparatus), it is the responsibility of the person in possession (owner or user) to submit it for periodic inspection within the interval specified in Annex B.
• In Annex B the interval for CO2, Nitrogen and Argon cylinders is 10 years.
“The Safe Use of Gas Cylinders” – a guidance document issued by the Health and Safety Executive – under the heading “How to reduce risks”, sub heading “periodic examination” makes references to Instruction P200 in ADR, as required by the Carriage Regulations. Instruction P200 also gives the periodic inspection intervals for CO2, Nitrogen and Argon cylinders as 10 years.
Therefore, all extinguishing agent cylinders (e.g. FM200 (HFC227ea), Inergen (IG541), Argon, Argonite (IG55), Nitrogen and CO2 etc) that are found to be 10 years old or more, their owner must be notified that the cylinders must be inspected, re-tested and certified accordingly.
Fixed Suppression Systems must comply with the following Regulations:
