Local Exhaust and Ventilation (LEV) Testing & Commissioning 

What is an LEV?

LEV is a ventilation system that takes dusts, mists, gases, vapour or fumes out of the air preventing exposure to the user/employee.

This includes Microbiological Safety Cabinets.

Do I need an LEV test and examination?

Health and safety law says you must assess the risks to your workers from hazardous substances – dusts, fumes, vapours, etc. - and decide what measures to use to protect their health.


If the measures you adopt include extraction systems (LEV) to remove the dusts, fumes, vapours etc. produced by your work processes or activities, then you must maintain the LEV in efficient working order so it continues to provide the necessary protection.


CoSHH Regulation 9 says you should have a periodic thorough examination and test at least once in every 14 months or more frequently as per Schedule 4.

What I provide

A comprehensive and thorough examination of all elements of the LEV system in place assessing the suitability and capability to control the hazard with Pass/Fail certification.


A detailed end report in full compliance with "Health and Safety Guidance HSG.258 Controlling airborne contaminants at work. A guide to LEV" 


All information considered will be provided in conjunction with recommendations where appropriate to give you the best straightforward practical advice to achieve compliance.
