What is an LEV?
Under the Control of Substances Hazardous to Health Regulations 2002 (COSHH), it is an employer’s responsibility to ensure that their staff are not exposed to dangerous airborne contaminants.
Local exhaust ventilation is an extract ventilation system that takes airborne contaminants such as dusts, mists, gases, vapour or fumes out of the workplace air so that they can’t be breathed in.
Properly designed LEV will:
- Collect the air that contains the contaminants
- Make sure they are contained and taken away from people
- clean the air (if necessary) and get rid of the contaminants safely
