Pressure systems

Pressure systems inspections

There are a number of statutory requirements that aim to ensure pressure systems - including boilers and steam systems, pressure cookers, refrigeration plant, and compressed air systems - are safe to use. These requirements are set out in the Pressure Systems Safety Regulations 2000 (PSSR).

What are the PSSR regulations?

Under PSSR, duty holders, users and owners of pressure systems are required to:

  • Establish the safe operating limits (pressure and temperature) of their systems
  • Ensure that a suitable Written Scheme of Examination (WSE) is in place before the system is operated
  • Ensure that the pressure system is actually examined in accordance with the written scheme
  • Carry out proper maintenance and provide suitable operating instructions.

Six-figure fines have been issued for the most significant breaches of PSSR, including incidents where people have suffered serious injuries due to failures in the operation of pressure vessel equipment.

How do I comply with PSSR?

Regular inspections, together with a planned maintenance programme, can help organisations comply with PSSR, while also promoting a safer working environment by identifying and helping to prevent plant breakdowns and resultant disruption.

Zurich Engineering’s engineer surveyors can prepare WSEs and carry out independent examinations of your pressure systems in accordance with the scheme. We will also inform you immediately if your pressure system, or part of it, needs urgent attention. To minimise disruption, where appropriate we can carry out examinations using the latest non-invasive inspection techniques, such as non-destructive testing or remote visual examination.

Zurich Engineering’s pressure systems expertise

As well as carrying out pressure systems inspections, and producing WSEs, we can:

  • Advise on what constitutes a pressure system
  • Advise on what parts of a pressure system should be included in a WSE
  • Assess and evaluate proposals for repairs/modifications to pressure systems to ensure this work will not affect the safety of the pressure system
  • Conduct inspections during repairs/modifications being carried out by contractors, to ensure the workmanship is of an acceptable standard and will not affect the integrity of the pressure system
  • Carry out fitness-for-service assessments of second-hand pressure plants or pressure plants that have significantly deteriorated during service.

The term - 'Competent Person'

The Management of Health and Safety at Work Regulations 1999, (MHSWR) Regulation 7 (1) states that every employer shall, subject to paragraphs (6) and (7), appoint one or more competent persons to assist him in undertaking the measures he needs to take to comply with the requirements and prohibitions imposed upon him by or under the relevant statutory provisions and by Part II of the Fire Precautions (Workplace) Regulations The Provision and Use of Work Equipment Regulations 1998, (PUWER) Approved Code of practice (ACoP) states that ‘The competent person should have the necessary knowledge and experience'.

Zurich Engineering as a 'Competent Person/Body'

In order to comply with the approved codes of practice for the regulations under which plant and equipment is subject to periodic in-service inspections or thorough examinations, a Competent Person is likely to be a corporate body rather than an individual because of the necessary requirement to have access to a wide variety of technical expertise and specialist services such as non-destructive testing (NDT). One indication of competence is accreditation and certification. For inspection bodies, there are several indicators of competence and Zurich Engineering hold the following:

  • UKAS accreditation - ISO17020 Type A inspection body.
  • UKAS accreditation - ISO17065.
  • Quality Management System Certification - BS EN ISO 9001.
  • Trade Association (SAFed) membership.
  • Compliance to SAFed Standard SS01 (assessed as part of Inspection Body accreditation).

Reporting status and defect code guide

Serious defects (AE)

This status indicates that a defect that poses (or could pose) a risk of injury to persons has been identified and that it must be reported to the enforcing authority. For most items, a defect that is required to be reported to the enforcing authority also poses an immediate or imminent danger to persons and the report will indicate this. For power presses, defects that need to be reported to the enforcing authority include those that do not pose immediate or imminent danger to persons. If the defect is not ‘immediate’, the report will indicate the date by which any rectification work should be undertaken.

Serious defects (AN)

This status indicates that a defect that poses (or could pose) a risk of injury to persons has been identified but that it does not require reporting to the enforcing authority. If there is immediate or imminent danger to persons, then the report will indicate this. If there is no immediate danger to persons, the report will indicate the latest date by which any rectification should be undertaken.

'B' defect (BD) or Other defect (in the case of power presses)

This status indicates that a defect has been identified but that, in the engineer surveyor's judgement, it does not pose a specific risk of injury to persons as defined in the respective regulations to which the item has been inspected. The defect should be assessed by the customer, as soon as reasonably practicable, and appropriate action taken if deemed necessary by the customer.

Deleted item (DL)

Indicates item has been removed from the schedule.

Not located (NL)

Indicates that an Engineer Surveyor has not been able inspect or thoroughly examine the item because the customer has not presented it for inspection or thorough examination and the engineer surveyor has been unable to locate or identify it.

Not available (NV)

Indicates that an item has been identified and located but we have not been able to complete an inspection or thorough examination because the item was not able to be inspected or thoroughly examined, e.g., out of service awaiting repair or not adequately prepared

OK

Indicates that an inspection took place and no defects were detected. However, the customer should view the reports for observations as these may provide useful information.

Customer advice (CA)

Indicates a Customer Advice, issued for important advice / informational purposes only.

Postponement (PD)

Indicates a Pressure item examination has been postponed in accordance with regulation 9(7) of the Pressure Systems Safety Regulations 2000 (PSSR)

General notes

We recommend that all reports of inspection and thorough examination are reviewed to ensure you are aware of the content.

Any item that has not been inspected by the due date on the current report of inspection or thorough examination should be taken out of service until the statutory inspection has taken place unless it has been postponed in accordance with regulation 9(7) of PSSR. Where defects have been identified and reported as requiring remedial action within a specified time, these should be rectified within the specified time period.

For all defects we recommend that the customer should review any relevant risk assessments and working procedures to ensure the continued safety of employees and other people that might be affected.

Managing statutory equipment can be difficult and needs tight control to avoid potential issues when equipment is used beyond its due inspection or thorough examination date. One way to control the use of equipment is to physically tag or “colour code” when it has been inspected or thoroughly examined and is safe to use.

Various types of colour coding can be used in different ways to distinguish when a piece of equipment is still safe to use and these options can be discussed with our teams

Whilst colour coding can be a cost-effective method of indicating the suitability of the equipment for further use, there are other options available for the control of equipment. Date stickers, date tags and rubberised tags are all potential options depending on the environment in which equipment is used, and Zurich Engineering are able to offer a number of options depending on your needs, so please speak to our teams to discuss.
