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.

Daily checklist for LEV

  • Does the indicator show the LEV is working properly?
  • Is it taking away all the harmful dust, mist, fumes and gas? Remember, some of these may be invisible.
  • Are you close enough to it so it can do its job properly?
  • Are there any signs it is not working properly, like smells or settled dust?
  • Are there any unusual noises or vibration coming from it?
  • Has it been thoroughly tested, with a 'tested' label that is within date?
