LOCAL EXHAUST Ventilation SYSTEMS

A Local Exhaust System is used to control air contamination by capturing contamination at or near the source, in a general way, it is like a household vacuum.

It is compulsory for businesses to adhere to COSHH requirements, which requires thorough testing of the LEV systems.

The LEV system is made up of 5 components.

  1. The hood which captures the contamination
  2. Ducts which transport the airborne chemicals
  3. Air cleaning device which removes the contaminate from the air systems.
  4. Fans which move the air through the system
  5. An exhaust which discharges contaminated air.
Why they need Testing

LEV testing is essential in protecting workers from hazardous dust and fumes.

They can range from simple single capturing hoods (e.g. welding) to large or complex systems such as paint spray booth enclosures.

Dust and contaminants in the workplace are a cause of thousands of fatalities each year in Britain. Mist from sprayers in paint shops, flour dust that circulates around many bakeries or fumes created by welding processes cause lung disease and asthma. Other causes could be vapour from evaporating paint solvents and even carbon monoxide created in furnaces.

OUR SERVICE

Our LEV testing services deliver reports to the criteria laid out in HSG258. A survey is conducted on each LEV system which documents the specifications for the fans, motors, ducting, hoods and fume cupboards as required by the regulations. We then produce a diagrammatic sketch for each LEV indicating the necessary test points. To aid compliance with regulation 8, the test points are distinctly marked, using labels detailing the individual test point number and the next test due date.

Each survey includes a visual and structural examination which involves taking mechanical measurements of performance (face velocities, static pressures etc.) and assessment of the control effectiveness (observations of employee / LEV interactions, smoke testing, dust lamp scans etc.). All the necessary documentation and test results are presented in a report to provide you with an easily manageable process for safe system compliance, and finally all testing of LEV systems should cause no disruption from our experienced engineers whilst they used the latest technology to each accurate results.

HSG258 recommends that each LEV has a logbook & user manual.

COSHH Regulations suggest that you should arrange a thorough examination and test your LEV system at least every 14 months. If any modifications are made to the system such as the layout or hood redesign, the previous report would not be valid, and the system would need to be recommissioned. In some cases, a LEV test needs to be performed every six months, or even every month.
