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?
- Have you told your supervisor about anything you think may be wrong?
