An LEV is a ventilation system that takes dust, mists, gases, vapour or fumes out of the air so that they can’t be breathed in. A properly designed LEV will collect the air that contains the contaminants; will make sure they are contained and taken away from people; clean the air (if necessary) and get rid of contaminants safely.

These include:

  • Woodworking dust extraction
  • Metalwork shops
  • Welding areas
  • Booths
  • Vehicle exhaust systems 
  • Many other systems found in industry, schools & colleges and small businesses.

Regular checks required by law

Once you have an LEV installed, the law says that you need to make sure it carries on working properly. You will need to regularly check and maintain the LEV and have it thoroughly examined and tested.

Most LEVs need a thorough examination and test once per year to make sure it works well and continues to protect the people within the working area. The examination tests the LEV against its performance and includes airflow and pressure measurements, checks on control effectiveness, and in some cases exposure measurement. If you should change the use of an LEV, then it should be re-commissioned to suit the new environment.

The examination and test should be carried out by a competent person and cannot be done in house or ‘do it yourself’.
