Written Scheme of Examination For Air Compressors
Is Your Air Compressor System Legally Compliant?
Your air compressor could be a ticking time bomb without proper inspection. If your system stores pressure exceeding 250 bar/litres, UK law requires a Written Scheme of Examination (WSE). This is not just paperwork – it protects your business, people, and equipment.
Control Gear has made compressed air installation compliance simple since 1973. Our WSE service ensures your system meets all legal requirements while preventing costly breakdowns and dangerous failures.
Need a WSE urgently or unsure if you are compliant?
What Is a Written Scheme of Examination?
A Written Scheme of Examination is a legally required document under the Pressure Systems Safety Regulations 2000 (PSSR 2000). It is essentially a detailed inspection plan for your compressed air system that:
- Identifies all pressure equipment and safety-critical parts requiring examination
- Specifies how often each component must be inspected
- Details the type of safety inspection needed for each part based on complexity and size
- Must be prepared by a ‘competent person’ or inspector with appropriate qualifications
‘According to the Health and Safety Executive, 90% of pressure system accidents are preventable with proper maintenance and inspection regimes.’
Key Components Covered in a WSE
| Component | What is Examined | Why It Matters |
|---|---|---|
| System Pressure Vessels (air receivers, tanks) |
Internal/external condition, welds, corrosion | Prevents catastrophic ruptures |
| Safety Valves | Calibration, operation, seals | Ensures pressure relief works when needed |
| Pressure Gauges | Accuracy, functionality | Prevents dangerous overpressurisation |
| Pipework | Connections, corrosion, supports | Prevents leaks and system failures |
| Control Systems | Function tests, safety interlocks | Maintains operational safety |
The Real Cost of Non-Compliance
Without a valid WSE, you are not just breaking the law – you are risking:
- Fines up to £20,000 for non-compliance with PSSR 2000
- Insurance invalidation if accidents occur
- Production downtime from preventable failures
- Legal liability for injuries or damage
- Reputational damage to your business
‘Recent industry data shows that unplanned downtime from air compressor failures costs UK businesses an estimated £180 million annually. Many of these failures could have been prevented with proper examination regimes.’
