Methods for Testing the Performance of LEV

P600 Methods for Testing Performance of LEV – Introduction

This one-day event has been designed to enable delegates to identify and correctly use appropriate LEV flow-visualisation and measurement techniques (LEV Test Instruments) to test the performance of Local Exhaust Ventilation (LEV) systems under supervision.

P600 – Methods for Testing the Performance of Local Exhaust Ventilation Systems focuses on the fundamentals of LEV systems, from their components to measurement and testing techniques. It will provide delegates with the necessary skills and knowledge to progress their career in LEV, and prepare them for taking BOHS Level 4 Proficiency qualifications (eg P601, P602).

P600 is a Level 31 LEV training course.

In general terms – delegates will gain knowledge and experience of:-

  • Basic components of local exhaust ventilation systems.
  • Qualitative visualisation techniques.
  • Quantitative measurement techniques.

This P600 Methods for Testing Performance of LEV training course is, for example, an ideal starting point for a delegate who wishes to progress in the field of LEV Examination and Testing but who requires an introductory foundation to the subject of using LEV test instruments etc (with limited maths!) which then allows them to gain further field experience before progressing to the Level 4 “Competency” P601 LEV course (LEV Examination & Testing).

1 The level of a course or qualification indicates the relative complexity and depth of knowledge and skills required to complete the course or qualification.  This course is set at Level 3 in the BOHS qualifications framework.


Delegates wishing to attend P600Methods for Testing the Performance of LEV” Webinar/On-Line training course are expected to have some basic knowledge of the measurement systems used to assess the performance of LEV systems.

There are no work experience requirements for attending P600, although it is an advantage for candidates to have worked in a role involving LEV.

Who should attend?

Anyone responsible for operating or maintaining LEV systems as part of their work.  This includes – for example – engineers, managers, supervisors, equipment designers, service engineers, technical sales staff and LEV technicians etc.

It is a very useful and practical training course for anyone who requires a foundation level of understanding of LEV systems in order to progress to a Level 4 qualification (P601-P604 series).  P600 is a Level 3 course.

The P600 qualification may also meet some requirements towards membership at the Society of Operations Engineers (SOE) and the Institute of LEV Engineers (ILEVE).

P600 LEV Course programme

Webinar/On-Line Presentation

  • Introduction to the basic components of local exhaust ventilation (LEV) systems (i.e. inlets, ductwork, air cleaners, air movers, ventilation hoods and discharges)
  • Demonstrate the use of smoke generators and/or smoke tubes to visualise air flows in and around LEV systems
  • Use of a dust lamp to visualise fine airborne dust
  • Using a pitot tube/manometer combination
  • How to carry out a Pitot tube traverse to determine static pressure (Sp), velocity pressure (Vp), and then calculate the velocity in a ducted ventilation system
  • Principle of operation of vane and hot wire anemometers
  • How and where to undertake measurements in relation to the inlets (hoods etc) of an LEV system
  • Chosing the correct test equipment to use and how to use them correctly

Practical Demonstration Session

Techniques to visualise air flows as a means of assessing the ability of LEV systems to control hazardous substances.

Use of smoke generators and/or smoke tubes.
Use of dust lamps.

Physical measurements; appropriate methods to actually measure performance of ventilation systems including operation of a Pitot tube/manometer combination. Measurement of air velocity with anemometers.

Personal protection requirements


At the end of the day there will be a one-hour on-line Multiple Choice Questionnaire (MCQ) examination comprising of 20 questions.  The exam will be marked by BOHS and on satisfactory conclusion of the MCQ, BOHS will award a “Course Certificate”.

Follow-on course

The P601 Thorough Examination & Testing of LEV Systems course is a natural follow-on from this course, as is the OXYL8 P602 LEV Design Training Course.

Success with OXYL8

We work very hard with all our students to try and ensure a pass ….. first time.  To assist we have comprehensive course materials and handouts, pre-course guides and support.  Our pass rate is excellent!
