LEV information for employees/users

Key messages for employees

  • Get involved in LEV design or selection.
  • Make sure you get training (in how the LEV works and how best to use it).
  • The LEV you use should have an airflow indicator (or equivalent).
  • The LEV should be easy to use properly; tell your employer if it isn't.

Local exhaust ventilation (LEV) in your workplace should carry away any harmful dust, mist, fumes or gas in the air.

To protect your health:

  • It needs to be the right type for the job.
  • It needs installing properly in the first place.
  • It needs regular checking and maintenance throughout the year.
  • It needs testing thoroughly at least once every year.
  • If you move LEV, make sure it still works.
  • It needs an indicator to show it's working properly.
  • You need to check that it works properly every time you use it.
  • You need to use it properly.

Check for yourself to see how effective the LEV is where you work.
