LEV Testing & Commissioning
  • Fume cupboards
  • Crown vent on circular saw
  • Dust extraction systems
  • Fume cupboards

Customers use LEV (local exhaust ventilation) systems to protect the working environment from hazards arising from, for example, laboratory fume hoods and cupboards, woodwork dust extraction, solder fumes, acid bath fumes, paint spraying booths and welding shops.

The hazards include those substances which are carcinogenic and cause occupational asthma.

COSHH regulations require that such LEV systems be tested and certified by a suitably qualified person at least every 14 months to ensure that they are operating effectively.  The test checks both the initial design, and current effectiveness of the LEV to ensure that the risk to the individual is minimised.

In a recent roadshow, the HSE estimated that some 40% of LEVs in operation in the UK go untested.  As well as the health implications for employees, employers should be aware that a failure to follow the regulations may lead to a criminal prosecution and/or personal liability if corporate insurances are invalid.

Roperhurst has been designing, commissioning and testing LEV systems for more than 35 years.  Our experienced staff can advise on effective design, and identify remedial actions should processes change or equipment need attention.

Our customers include several local authorities as well as major industrial companies and NHS Trusts throughout Wales, the Midlands and South West.

Many suppliers of LEV systems imply that only they can service the equipment.  Roperhurst has worked with equipment built by all of the major UK fume cupboard and dust extraction manufacturers, and has installed and serviced LEV equipment across Wales, the South West and the Midlands.

If you think you may have an LEV, or may need an LEV, and want to know what to do next, please contact us. Initial guidance is also available on the HSE's website.
