Frequently asked questions
How often does LEV need to be tested?
How long do I need to keep LEV test records?
Do LEV hoods have to have airflow indicators?
There is no specific legal requirement to fit airflow indicators [23], but you should have some way of checking that adequate airflow is being maintained [24]. HSE notes that an airflow indicator is currently the only method that shows the operator or supervisor immediately if there is a problem [34].
Does LEV have to be labelled after testing?
There is no specific legal requirement on employers or examiners to label LEV [38]. HSE guidance recommends that examiners label each hood with a test record [37], and put a red "Failed" label on any hood or system that has failed [47]. After repair, a competent person checks that it is effective before the label comes off [28].
