WRITTEN SCHEME OF EXAMINATION (WSE)
PSSR 2000 Compliance for Compressed Air Systems
Preparation of Written Schemes of Examination and inspection of compressed air systems in accordance with Pressure Systems Safety Regulations.
✔ Suitable for insurance and compliance requirements
✔ Covers compressed air systems and associated equipment
✔ Clear documentation and reporting
DO YOU REQUIRE A WRITTEN SCHEME OF EXAMINATION?
Understanding Your Obligations Under PSSR 2000
Many compressed air systems fall under the Pressure Systems Safety Regulations (PSSR 2000), which require a Written Scheme of Examination to be in place.
Typical situations include:
- no formal Written Scheme in place
- uncertainty regarding inspection requirements
- incomplete or outdated documentation
- inspections not aligned with system use
The requirement depends on system configuration, pressure and stored energy.
WSE & INSPECTION SERVICES
Written Schemes and System Inspections
We prepare Written Schemes of Examination and carry out inspections in line with regulatory requirements.
Services include:
- preparation of Written Schemes
- identification of relevant system components
- inspection of air receivers and associated equipment
- safety valve and pressure gauge checks
- reporting for compliance and record keeping
From System Review to Documentation
1. System Assessment
Review of your compressed air system to determine what falls under PSSR requirements.
2. Scheme Preparation & Inspection
Creation of a Written Scheme covering relevant equipment and inspection intervals. Inspection of identified components in accordance with the scheme.
3. Reporting
Provision of documentation suitable for compliance and record keeping.
SYSTEM COMPONENTS
Equipment Typically Included
- air receivers
- safety valves
- pressure gauges
- associated pipework
- relevant pressure system components
Scope depends on system design and operating conditions.
WHY A WRITTEN SCHEME IS REQUIRED
Safety and Compliance
A Written Scheme of Examination defines how a pressure system is inspected to ensure safe operation.
Without a suitable scheme:
- inspection requirements may not be clearly defined
- system condition may not be properly assessed
- compliance with PSSR may not be met
A structured approach helps ensure safe and consistent operation.
OUR APPROACH
Practical and System-Focused
We work with compressed air systems daily, which allows us to take a practical approach to both documentation and inspection.
- understanding of real system operation
- clear and relevant reporting
- inspections aligned with actual usage
The focus is on producing documentation that is usable and appropriate for the system.
FREQUENTLY ASKED QUESTIONS
Written Scheme of Examination FAQs
Do all compressed air systems require a Written Scheme?
Not all systems require a scheme. The requirement depends on pressure, volume and stored energy. We can advise based on your system.
What does a Written Scheme include?
It defines which parts of the system must be inspected, how inspections are carried out and the required intervals.
How often are inspections required?
Inspection intervals are defined within the Written Scheme and depend on system type and use.
Can existing systems be assessed?
Yes — we regularly review and prepare schemes for systems already in operation.
Is the Written Scheme required for insurance?
In many cases, insurers require evidence of compliance with PSSR, including a Written Scheme and inspection records.
