EEMUA has released Edition 2 of EEMUA 231, The mechanical integrity of plant containing hazardous substances – a guide to periodic examination and testing.

EEMUA 231 provides guidance and good practice on safely managing the combined hazards of stored energy and dangerous substances through maintaining the integrity of systems and equipment by periodic examination and testing.

The guidance covers all onshore equipment that provides the primary containment boundary to hazardous substances, which will include pressure vessels, relief streams, atmospheric storage tanks, reactors and pipework. It will cover machines such as pumps, agitators, valves and compressors in so far as they are required to maintain primary containment.

The hazardous substances considered include those with the potential to cause harm (either to people and/or the environment) because of their toxicity, flammability or other form of chemical reactivity (including explosivity).

This new edition adds a section on leadership, a fundamental aspect of managing health and safety effectively, and provides guidance on the relief streams that protect equipment or systems. The publication has also been given greater clarity by combining the sections on Reporting of Examinations and Post Examination Integrity Assessment. There is also a clearer demarcation between the roles of Integrity Assessor and Competent Person.

A free digital edition can be downloaded from the online Shop. Printed copies are available to buy.

EEMUA 231 provides the foundation for the EEMUA training course on Mechanical Integrity and key aspects of the publication are the basis of EEMUA's Mechanical Integrity e-learning training course

Any organisation that has hazardous installations, together with interested stakeholders who use such plant, including operators, inspection bodies (including 'Competent Persons') and providers of specialist services to the process industries, should find EEMUA 231 and the related training and e-learning of interest.
