P602 Course Overview
The P602 LEV Design course is a 4-day training programme offered as a Webinar/On-Line (‘live’ using Zoom) or as a face-to-face event (usually at the Leicester Hilton Hotel).
Payment is not required at checkout as Invoices will be sent approx 5-6 weeks before the course.
P602 equips delegates with the methodology, theoretical knowledge and practical skills to design basic Local Exhaust Ventilation (LEV) systems for controlling occupational exposures to hazardous substances.
Delegates learn how to accurately specify LEV systems including performing Benchmarking calculations, using Fletcher’s Equations appropriately and calculating system pressure loss and flowrate requirements.
Upon completion of the P602 LEV Design course delegates should be able to:
- Select the correct Hood required using Benchmarking techniques
- Design basic Partial Enclosures, Captor Hoods, Receptor Hoods etc
- Conduct a full Design exercise for a basic LEV system
- Perform Commissioning tests to assess how effective a system is and if it is operating to design specification
- Prepare suitable records based on the design.
It is desirable for candidates to have:-
- Successfully completed P601 “Thorough Examination & Testing of LEV Plant”, or demonstrate an equivalent level of learning
- A good understanding of HSE’s Guide HSG258 “Controlling Airborne Contaminants at Work“
- Competency in basic maths including algebraic calculations such as areas of circles and square roots, etc.
No other specialist knowledge is required.
Who should attend?
This course is suitable for engineers, supervisors, managers, health and safety professional and technical staff involved in the specification, design, testing, contract management, and occupational hygiene aspects of LEV plant.
Towards professional recognition and qualification?
The P602 proficiency qualification can be combined with other BOHS modules e.g. P601, P603, P604 and W201 to achieve further professional recognition through BOHS. Succesful candidates may add these qualifications to progress to the award of the Certificate of Operational Competence in Control – allowing them to use the post-nominal letters ‘CoC Control’ after their name.
On completion of the entire ‘P’ series of LEV training courses (including W201) candidates may also be eligible for membership of BOHS as a Licentiate of the Faculty of Occupational Hygiene (LFOH(S)). See BOHS for more details.
