Frequently asked questions

How often does LEV need to be tested?

Usually at least every 14 months [21]; the specified Schedule 4 processes have 1-month or 6-month limits [1]. The interval can also be shorter: the commissioning report should say if the testing frequency differs from the statutory 14 months [5].

How long do I need to keep LEV test records?

Keep the thorough examination and test record for at least 5 years [21]. Information on the installed system that shows it gives adequate protection, such as the commissioning report, should be kept for the life of the equipment [35].

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].
