Local Exhaust Ventilation (LEV) Testing.

Written by

What is LEV Testing:

Local exhaust ventilation (LEV) checks, help control the release of hazardous airborne substances from a process into the workplace environment.

Why carry out LEV testing:

The aim of LEV checking is to control the emission as close as possible to the point of release, and prevent it from entering the air of the workplace.

Who should carry out LEV Testing:

Anywhere with extraction units and/or that produces fumes, a few examples of workplaces and processes include:

  • Wood and carpentry manufacturers
  • MOT Stations
  • Restaurants with exhaust ventilation units
  • Industrial processes that produce paint fumes and solder fumes
  • Shot blasting and sand blasting processes
  • Air conditioning units
  • Furniture makers  

What we can offer:

Envirochem routinely undertake LEV checks for many clients on equipment including:

  • Fume cabinets
  • Spray booths
  • Dust extract systems
  • Air conditioning units
  • Exhaust ventilation units
  • Extractor fan units

These should be tested 14 monthly or after any modifications, as specified within the Health and Safety Executive’s HSE Guidance Notes HS(G)54 and HS(G)37.

We produce thorough reports detailing duct velocities static pressures and flow rates and make comments on any observed changes in the system reading or their possible causes.

Local Exhaust Ventilation (LEV) testing

Written by

The continued and increasingly widespread occurrence of occupational related lung diseases in the UK has lead to stringent guidelines and requirements for Local Exhaust Ventilation (LEV).

Nearly a decade ago in May 2008, the Health and Safety Executive (HSE) published a new guide (HSG258) on LEV for various occupations, such as designers, installers and examiners, as well as guidance for employers and their employees who depend on sufficient LEV for their wellbeing.

COSHH regulations require that all LEV systems to be tested every 14 months to ensure that they are operating well enough to protect workers who depend on these systems for their safety. Systems that require testing include all oil mist, welding fume, smoke and dust extraction units. These examinations must be undertaken by competent personnel who work and provide reports according to HSE standards. Inadequate testing can result in employers being prosecuted, insurance being invalidated and employees getting ill.

For nearly 30 years Envirochem has provided comprehensive LEV testing in accordance with HSG258 guidelines. An Envirochem examination measures air flow speed (velocity) of air being extracted from the source and in the ductwork. These results are then compared to recommended velocities set by the HSE. Our vast experience in the area of occupation hygiene allows us to provide practical advice and recommendations.
