LEV stands for local exhaust ventilation. This is term relates to the control of dust or fumes, for example, in an extraction system. The LEV should be tested regularly to ensure that it provides adequate protection for the workers. According to government legislation HSG258, LEV testing should take place once in every 14 month period and the tests should be held on file for 5 years. The LEV examination checks that hoods are capturing sufficiently and that there are no leaks or blockages which may allow harmful contaminated air into the workspace.

Any system that is designed to protect an operator requires an examination at least once in every 14 month period. To make this easy to plan, we recommend that these be conducted annually. This should cover any welding fume, smoke, or dust extraction systems. Our LEV testing examinations include an in-duct velocity and static pressure test, an assessment of each machines’ capture capability and a full written report for your records.

Testing Regulations

Since the HSE released a report on Occupational Lung Disease in Great Britain in 2017, there has been increased awareness of the importance of LEV testing, which led to stricter guidance and legislation. CoSHH regulations require that your LEV equipment must be tested at least once every 14 months to protect your workers and keep your staff safe.

The HSE published detailed LEV guidance in their third edition of HSG258 in 2017, which provides information on the design, commission and testing of LEV equipment to ensure safety. We at Extraction Solutions work in strict accordance with the HSE legislation and can provide reliable and qualified LEV testing services.

As well as LEV testing, we also provide practical recommendations to improve your extraction system so it better complies with regulations and is less likely to become a risk in the near future. We work to ensure the health and safety of your staff members.
