EEMUA Publication 177 Guide to the UK Pressure Systems Safety Regulations (2000)

Version: Digital/PDF

If you are a user from an EEMUA member company, please log in and download your complimentary digital edition here.

EEMUA Publication 177 gives practical guidance on the interpretation of the UK Pressure Systems Safety Regulations (PSSR) 2000 relating to the periodic Examination of Pressure systems and certain associated aspects, and considers in particular Regulations 2, 7, 8, 9, 10 and 13, plus Schedule 2. The PSSR contains a complex series of requirements and allows for a considerable element of experienced, professional judgement by the User and/or Competent Person, together with a demand for careful interpretation.

Significantly, the new edition of EEMUA 177 includes guidance on the Postponement of Examinations within Regulation 9; a revision to the guidance on Regulation 10 Action in case of Imminent danger; additional guidance on Regulation 13 Modification and repair; together with other key points of interest based upon actual use of Pressure systems covered by the PSSR.

EEMUA 177 brings clarity by explaining how to approach specific aspects of the PSSR and helps minimise unclear areas that can cause confusion about what to do with respect to the Regulations. An example of this is with Regulation 10 wherein EEMUA 177 provides a flowchart that helps the Competent Person decide whether it is a case Imminent danger and needs to be reported to the HSE. The requirements under Regulation 10 are also given context with other relevant legislation. 

This publication was produced by a working group of EEMUA’s User Inspectorate Committee (UIC), which brings together experts from a range of industry sectors. Whilst the guide refers throughout to UK regulations and practice, much of the general advice is relevant to practice outside the UK.

EEMUA 177 does not refer in detail to the other Regulations already clearly expounded in the British Health and Safety Executive (HSE) Approved Code of Practice, Safety of Pressure Systems (ACOP) L122, which is freely available from the HSE. This EEMUA guide, therefore, should not be read in isolation, but should be used to augment the existing ACOP.  

The guidance and good practice in EEMUA 177 and 231 can be applied on site through taking the EEMUA Mechanical Integrity Practitioner Certificate, a blended online learning training course. At the awareness / introductory level, you may be interested in taking the EEMUA 177 Pressure Systems e-learning and EEMUA 231 Mechanical Integrity e-learning training courses.

EEMUA Publication 183 Prevention of tank bottom leakage - a guide for the design and repair of foundations and bottoms of vertical, cylindrical, steel storage tanks

Version: Digital/PDF

If you are a user from an EEMUA member company, please log in and download your complimentary digital edition here.  

Leakage from storage tanks may lead to extensive environmental pollution and be a financial loss to owners. This guide addresses the problem of tank leakage caused by loss of integrity. Such loss is almost always caused by deterioration of the tank bottom, which itself may be caused by corrosion or by deterioration of the foundation. This second edition is a comprehensive update that takes account of changes in standards, regulations and improvements in technology. EEMUA 183 gives guidance on a range of topics affecting tank bottom integrity including: design considerations for various types of tank foundations and bottoms; causes of tank bottom leakage; inspection records and techniques; corrosion protection; leak detection systems; and membranes as soil barriers.

EEMUA also offers introductory e-learning in the area of Storage Tanks in both Dutch and English language versions.

2019, Edition 3

EEMUA Publication 184 - Guide to the isolation of pressure relieving devices

Version: Digital/PDF

If you are a user from an EEMUA member company, please log in and download your complimentary digital edition here.

In order to permit their removal and replacement without plant shutdown, pressure relieving devices may need to be isolated from the equipment they protect. However, the installation of isolating valves around protective devices is potentially hazardous as it introduces the risk of a system being left unprotected against over-pressure due to the relief path being inadvertently closed off. Existing standards offer little or no detailed guidance in this area.

EEMUA 184 plugs the gap by expanding on the guidance given in API RP 520 Part II and incorporating EEMUA Information Sheet 50 - The Importance of isolation management around relief systems. It outlines the case for using relief valves as a layer of protection, gives advice on managing safe isolation and stresses the importance of safe de-isolation after completion of relief system work. EEMUA 184 provides several examples in loss prevention history where the failure to adequately manage relief system isolations has been a major factor in causing process safety incidents.

It is essential to conform to local statutory legislation or regulations in relation to the use, and isolation of, relief devices. In some countries, conformance to certain standards and codes may be a mandatory requirement and specific standards, such as those pertaining to boilers, may specifically prohibit the installation of isolation devices.

EEMUA Publication 185 Guide for hot tapping on piping and other equipment         

Version: Digital/PDF

If you are a user from an EEMUA member company, please log in and download your complimentary digital edition here.

Hot tapping, the term used when a branch is connected to a live or 'hot' piping system, is potentially hazardous particularly where flammable or toxic fluids are present. This publication offers guidance on how to carry out a safe and successful operation when hot tapping into metallic piping systems containing process fluids or their residues. It covers overall planning of the operation and includes hazard assessment and control, the constraints imposed by the nature, temperature and pressure of the process fluids, welding, testing and cutting (drilling/trepanning).
