Written Scheme of Examination

Written scheme of examination

All new and existing compressed air installations must conform to the Pressure Systems Safety Regulations (PSSR2000). All pressure systems larger than 250 bar/litres must have a ‘written scheme of examination’ and a statutory inspection in accordance with the written scheme. A written scheme of examination has two parts

Part 1 (Section 8) 'the report'

A written scheme of examination consists of two parts. Part 1 (also known as section 8) - is a report that details safety devices and pressure vessels in your compressed air system. The report also includes inspection periods for each device or pressure vessel and, in some cases, a schematic drawing of the whole compressed air network. As your compressed air system changes and is developed the report needs to be updated to reflect these changes. The report is effectively a safety check sheet for your unique compressed air system. The report can only be written by an authorised individual with the correct qualifications and experience.

Part 2 (Section 9) 'the inspection'

Part 2 (also known as section 9) - Is the annual inspection of the compressed air system with focus on the fitted safety devices and the pressure vessels carried out based on the latest version of the report created in Part 1 above. Any changes to the compressed air system that have been included in the report need to be included in the inspection process. The inspection can only be carried out by a suitably qualified individual. Air Compressor Centre is able to provide all the necessary services to obtain a written scheme of examination for your compressed air system.
