P600 – Methods for Testing the Performance of LEV Systems
BOHS Level 3 Qualification
P600 is a one-day introductory programme designed to develop the foundational knowledge required to understand and undertake performance testing of Local Exhaust Ventilation (LEV) systems under competent supervision.
Delivered via Live Interactive Webinar and Face-to-Face training, this course provides the essential starting point for those beginning their progression within the LEV profession.
Who Should Attend
This course is suitable for:
- New entrants to the LEV industry
- Engineers and technicians supporting LEV testing work
- Health & Safety professionals seeking technical insight
- Individuals progressing toward BOHS Level 4 qualifications (P601–P604)
Course Overview
The programme introduces delegates to:
- The core components of LEV systems
- Fundamental performance measurement techniques
- Qualitative and quantitative testing methodologies
- The correct selection and use of LEV test instruments
P600 is a Level 3 qualification and often serves as the first step toward professional development within the LEV field.
What You Will Learn
By the end of the course, delegates will understand:
- The structure and function of LEV system components
- Flow visualisation techniques (smoke tubes, smoke generators, dust lamps)
- Quantitative measurement methods (Pitot tubes, manometers, vane and hot-wire anemometers)
- How to undertake duct traverses and interpret velocity and pressure readings
- Where and how measurements should be taken in relation to LEV hoods
- The foundational mathematics underpinning higher-level BOHS qualifications
Important Note on Competency
P600 does not confer competency to undertake statutory Thorough Examination and Testing (TExT) under COSHH Regulation 9 without supervision.
It provides the essential knowledge base upon which competence can later be developed through further training and supervised experience.
Assessment
At the conclusion of the course, delegates complete a 20-question Multiple Choice Questionnaire (MCQ).
- Duration: 60 minutes
- Marked by BOHS
- Successful candidates receive the BOHS P600 Certificate
P600 is Delivered in the Following Formats
- Live interactive webinar (Zoom)
- Face-to-face training (typically Hilton East Midlands, J24 M1)
- This course is also available for in-house presentation
Fees
£395 + VAT
BOHS examination fee: £80 + VAT (reviewed annually by BOHS)
Invoices are issued approximately 5–6 weeks prior to the course start date.
Progression
P600 is a natural precursor to:
P601 – Thorough Examination & Testing of LEV Systems
Delegates progressing toward Level 4 qualifications typically move into the P601–P604 series following this course.
Professional Recognition
The P600 qualification may contribute toward entry requirements for membership of the BOHS and the Society of Operations Engineers (SOE).
