The Pressure Systems Safety Regulations 2000 require pressure systems to be inspected in accordance with a Written Scheme of Examination. These are integral parts of your PSSR Inspections.
The Regulations apply to owners and users of systems containing ‘relevant fluids’, (which include steam, gases under pressure and any fluids kept artificially under pressure and which become gases when released into the atmosphere).
If a boiler operates at 100°C and over, it comes under the Pressure Systems Safety Regulations. However, it is recommended that all hot water boilers be inspected. In addition, the PSSR Regulations cover refrigeration and air conditioning plants with compressor motors which exceed 25kW, or where the total installed power exceeds 25kW.
There is a legal requirement for thorough examination of pressure vessels and receivers that contain steam and compressed air. Any pressure vessel containing compressed gas over 250 bar / litres capacity requires inspection.
To establish whether your vessel requires PSSR Inspections, multiply your vessel’s normal operating pressure (in bar) by the vessel capacity (in litres) i.e. 10 bar x 50 Litres = 500 bar / litres Capacity and therefore is above the 250 bar / litre threshold and requires a PSSR Inspection with a Written Scheme of Examination.
If your pressure equipment fails, you (as the business owner) could be responsible for seriously injuring or killing staff and/or visitors, and damaging property and equipment. It could keep your business from operating at normal output and efficiencies and cost you a lot of money in the long run.
These Regulations (PSSR 2000) cover the ‘in-service;’ use of pressure systems, and have the status of a Statutory Instrument (SI128). Non-compliance is a criminal offence.
Following the initial system assessment, a Written Scheme of Examination must be drawn up by a competent person, and must include a definition of the items included in the system and details of frequency of examination under your PSSR Inspection schedule.
A “Written Scheme of Examination” is a legal document that details the items within a pressure system that need examination by a competent person. These items cover a wide range of products and pressure equipment that are installed into a pressure system; and include pressure gauges, pipework, safety valves, control manifolds, and more.
The WSE specifies the items for examination, a frequency for the examinations (every 12 or 24 months and so on) and contain the detail as to how the pressure equipment is to be examined. If any special conditions or measures are required to prepare the system for safe examination, then these would be included in the WSE.
The pressure system must be inspected in accordance with the Written Scheme, and suitable reports compiled and retained. These tasks are completed by the Competent Person(s) approved by the system owner.
PSSR Inspections procedures normally include both a thorough examination (with the system being shut down and vessels opened up) and/or a working examination of the system under normal operation. Inspection intervals under the Written Scheme may vary according to the application of the system(s).
Firstly we will review your existing documentation, then we come and complete a simple system inspection. Then we will complete a more invasive inspection; listing what’s out of date, existing replacement dates, any necessary repairs and/or replacements, with a pressure test (to MAWP or 1.1 etc.) and/or a leak test. We will then list any necessary or recommended remedial works.
Your PSSR Inspection’s Written Scheme of Examination will be completed, and we will do a full document handover.
We work very closely with CTM Europe of Cardiff, a well-respected and experienced pressure system and industrial gas engineering company. Our bible is BCGA Code of Practice 4 (CP4).
