Background  I have run successful courses on a wide range of occupational hygiene topics over the last 30 years.  The only one I now run is a one-day course, aimed at employers, and their advisers, entitled “Practical Management of Local Exhaust Ventilation (LEV) Controls”. It is practical, hands-on and well-received by delegates.

LEV hood demonstration

I run it at HSE’s Health and Safety Laboratory (HSL) with John Saunders link.  The Course is BOHS-endorsed course (BOHS). Its development was supported by HSE. A Safety and Health Practitioner article summarises the issues employers face (link).

LEV Working Demonstration Model The model is used extensively in the Course to practically demonstrate strengths, weaknesses and key design features of LEV hoods. It makes the key ‘learning points’ come alive.

The model was developed from an earlier ‘Heath Robinson’ effort (made of cardboard) in the 1990s, I used for training HSE inspectors. In 2008 it was “highly commended” at the British Safety Industry Federation (BSIF) innovation award ceremony (PDF). Manual gives more details here.
