P602 Basic Design Principles of LEV Systems

P602 Course overview

This 4-day P602 LEV Design course delivered as a Webinar/On-Line event, provides the methodology, theoretical and practical knowledge to enable delegates to design basic LEV systems for controlling occupational exposures to hazardous substances.

Delegates will learn the basic skills to correctly specify LEV systems, including performing calculations for; eg, Benchmark correct hood selection, Fletcher’s Equations for captor hood design, system pressure losses, specifying appropriate fans etc.

Learning objectives

On 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
  • Undertake a full Design exercise for a basic LEV systems
  • Undertake Commissioning tests to determine if the system is effective and operating to design specification
  • Prepare suitable records of the basis of design.

Pre-requisites

It is desirable for candidates to:-

  • have successfully completed P601 “Thorough Examination & Testing of LEV Plant”, or be able to demonstrate an equivalent level of learning
  • have a good understanding of HSE’s Guide HSG258 “Controlling Airborne Contaminants at Work

Delegates must be competent in basic maths/algebra (such as being able to calculate areas of circles, use square roots, etc.)

No other specialist knowledge is required.

Who should attend?

Engineers, supervisors, managers, health and safety professional and technical staff who have day to day dealings with the specification, design, testing, contract management, and occupational hygiene aspects of LEV plant.

Towards professional recognition and qualification?

The P602 qualification can be added to other BOHS modules e.g. P601, P603, P604 and W201 (in various combinations) to gain further professional recognition through BOHS, e.g. Certificate of Operational Competence in Control – which permits the successful candidates to use the post-nominal letters ‘CoC Control’ after their name.

In combination with the remaining P600 series of LEV training courses (and W201) candidates may also be eligible for membership of BOHS as Licentiate of the Faculty of Occupational Hygiene (LFOH). See BOHS for more details.

Customer Reviews

“Bill I must thank you for a very enjoyable LEV course. I have to say that, the way you developed the information was first class – the delivery was fluent, natural – in fact it came across as extemporaneous! It was also very informative about the subject so as to enable us to undertake the practical aspects out on site. I don’t profess to be an expert in such matters – but I thought it was very well done and it’s no surprise that your pass rate is high. ( I just hope to be in that statistic!)”

“I would like to give Bill Cassells a huge shout-out. Absolutely fantastic Tutor with more knowledge in LEV training than anyone I have ever met. Just received my LEV certificates today in both P601 and P602. Without the help of Bill this probably wouldn’t have happened. Anybody thinking on doing these LEV courses, look no further than this Man. I will hopefully be doing the P604 Course at some point also.”
