In the UK most gas loaded accumulators will require examination to ensure compliance with PRESSURE SYSTEMS SAFTEY REGULATIONS P.S.S.R. (SI 2000 No. 128).

The following is a direct link to the regulation itself

• P.S.S.R. (SI 2000 No. 128)

Below are the links to Health and Safety Executive leaflets which explain the PSSR in more straightforward terms.

• Written Scheme of Examination
• Pressure Systems - Safety and You

The key points relating to the legislation are as follows:

• Nitrogen Gas filled accumulators are designed to store energy.
• The regulations are designed to reduce the risk of a sudden release of stored energy
• Safe operating limits are established by checking and recording that the maximum system pressure does not exceed the maximum working pressure of the accumulator
• Relevant records are maintained and compliance can be demonstrated.
• An established maintenance procedure is required and regular checks are carried out
• A competent person needs to be appointed to prepare a written scheme of examination.

Professional assistance can be provided by authorised FCH accumulator recertification centres situated throughout the UK.
