P601 – Thorough Examination & Testing of LEV Systems
BOHS Level 4 Qualification
P601 is an advanced training course designed to develop the knowledge and practical understanding required to undertake statutory Thorough Examination and Testing (TExT) of Local Exhaust Ventilation (LEV) systems in accordance with COSHH Regulation 9.
This qualification is a critical step for those seeking to demonstrate professional competence in the examination and performance verification of LEV systems.
Who Should Attend
This course is suitable for:
- Engineers and technicians responsible for conducting LEV Thorough Examination and Testing
- LEV Specialists progressing from P600 toward Level 4 competence
- LEV practitioners seeking formal BOHS qualification
- Those involved in Commissioning, Maintenance or Performance Verification of LEV systems
- Duty Holders who wish to increase their knowledge of LEV Examination & Testing
Course Overview
The programme provides in-depth coverage of:
- Legal requirements under CoSHH Regulation 9
- The principles and objectives of Thorough Examination and Testing
- Quantitative measurement techniques and performance assessment
- Interpretation of test data and comparison with design specifications
- Preparation of compliant LEV TExT reports
P601 is a Level 4 qualification and forms part of the BOHS P600–P604 professional development pathway.
What You Will Learn
By the end of the course, delegates will understand:
- The statutory framework governing LEV examination and testing
- How to assess LEV system performance against design intent and regulatory requirements
- How to carry out and interpret airflow, pressure and velocity measurements
- How to evaluate hood capture effectiveness
- How to identify system deficiencies and make evidence-based recommendations
- How to produce structured, legally defensible TExT reports
Practical Application
The course includes applied technical exercises and worked examples designed to reinforce measurement techniques, calculations and report preparation.
Delegates are expected to have prior foundational knowledge of LEV systems (typically through P600 or equivalent industry experience).
Important Note on Competency
Successful completion of P601 demonstrates knowledge and understanding of Thorough Examination and Testing principles.
However, competence to undertake unsupervised statutory TExT requires appropriate workplace experience in addition to qualification.
Assessment
The qualification assessment consists of:
- Two written examinations, marked by BOHS
- A Formative Practical undertaken on the penultimate afternoon
- Structured technical questions assessing applied understanding
- Following completion of the written exams, delegates will be required to submit 2 TExT Reports undertaken by them on LEV systems. These Reports will be marked by BOHS
On successful completion of the written exams and submission of TExT Reports, candidates are awarded the formal BOHS P601 Certificate.
Delivery Formats
- Live interactive webinar (Zoom)
- Face-to-face training (typically Hilton East Midlands, J24 M1)
- Available for in-house delivery by arrangement
Fees
£1485 + VAT
BOHS examination fee: £355 + VAT (reviewed annually by BOHS)
Invoices are issued approximately 5–6 weeks prior to the course start date.
Progression
P601 forms part of the BOHS Level 4 Certification in Local Exhaust Ventilation.
Delegates typically progress to:
P602 – Basic Design Principles of LEV Systems
P603 – Control of Hazardous Substances
P604 – Performance Evaluation of LEV Systems
Professional Recognition
The P601 qualification supports progression toward professional membership of BOHS and the Society of Operations Engineers (SOE). P601 is widely recognised within the LEV industry as a minimum benchmark qualification for TExT practitioners.
