An LEV (Local Exhaust Ventilation) system is an engineering control designed to reduce workers’ exposure to airborne hazards. In particular, it removes hazardous substances away from process operators. In addition, it stops these substances from re-entering the workplace air. It therefore also protects operators working away from the process. With this in mind, LEV owners should Complete regular LEV Testing, so that they can be sure that the system continues to protect the workers.

There are many types of systems:

  • Total Enclosures.
  • Partial Enclosures.
  • Fume Cupboards.
  • Down Flow Booths.
  • Walk-in Booths.
  • LEVs that Capture the contaminants.
  • Systems with Receptor hoods to receive hazards.

Many extraction systems can have a combination of hoods and booths. Usually, LEVs will have the following parts: Hoods, ducting, an air cleaning device, an air moving device, and a discharge point.

Complying with COSHH Regulation 9

To ensure LEV systems are working correctly and to comply with Regulation 9 (COSHH), companies must undertake routine LEV testing. Employers must carry out this test once every 14 months. But some, systems require testing more often. How often depends on the process and the substances they control.

Why Choose Synergy to test your LEV System?

LEV testing should be carried out by a competent person.

When choosing a supplier it is important to choose a company with competent staff. The testing, is otherwise known as a Thorough Examination & Test (TExT). The word “Thorough” is the most important word in this sentence.

The Management of Health and Safety at Work Regulations 1999 States that companies must use a competent person to look after their health and safety. For example, where they expose workers to hazardous substances, it advises that a competent person should undertake the LEV Testing. The person that comes to do the assessment should have a certificate of competence to carry out the work.
