Pipework Distribution & Pressure Testing
British Compressed Gases Association (BCGA) Code of Practice CP4 refers to the application of Industrial Gas Cylinder Manifolds and Gas Distribution Pipework.
8.2.2 Annual Inspection (by a person withappropriate experience and knowledge)
It states that :-
All repairs and modifications (including removals and additions of components) and extensions carried out conform to this Code of Practice.
The system is free from leaks by testing at the designated operating pressure.
Additionally, the Provision and Use of Work Equipment Regulations 1998 require risks to people’s health and safety from equipment that they use at work to be prevented or controlled. In general, the regulations require that equipment provided for use at work is
a) suitable for the intended use
b) safe for use, maintained in a safe condition and in certain circumstances, inspected
to ensure this remains the case • used only by people who have received adequate
information, instruction and training and accompanied by suitable safety measures
e.g. protective devices, markings, warnings
Consequently, pipework that carries gases or cryogenic liquids under pressure must be suitable for the intended use, safe for use and maintained in a safe condition.
Points to Consider – The HSE & YOU
With respect to PSSR, the relavant points HSE Inspectors are looking for within the regulations are:
• The method on which the safe operating limits of the system have been established (Reg 7)
• Possession of an appropriate Written Scheme of Examination (Reg 8)
• Proper and timely inspection and maintenance (Reg 12)
The Regulations bestow certain powers on the HSE Inspector, they can:
1- Give advice during a site visit and insist on improvement(s) when appropriate
2- Issue a Legal Notice on the owner/user of a pressure system / piped system,
giving either :-
a) 21 days notice to carry out corrective action or
b) a Prohibition Notice which stops work immediately – in other words, they can close premise / —– places of work down under these regulations
c) Carry out a Prosecution
Anyone prosecuted by the HSE successfully through Magistrates Court could find themselves with a fine of up to £20,000.
Anyone prosecuted by the HSE successfully through Crown Court could find themselves facing an unlimited fine and / or imprisonment for the responsible people (usually the MD or General Manager).
