Local Extract Ventilation (LEV) is the name given to equipment used to protect an operator from hazardous substances including dusts, chemicals or micro-organisms.
Contaminants which require exposure control may be in the form of gas, vapour, mist, dust/powders, and nano materials and can include chemical substances (carcinogens, mutagens, toxins, flammable solvents) and micro-organisms.
LEV can take a variety of forms depending on the type of contaminant /process that it is to control exposure to. University Guidance (Appendix 1) shows a variety of different types of LEV that may be in use within the University to control exposure and therefore that will fall within the scope of the policy and HSE Guidance.
For further detail on this topic, please refer to the University's guidance which has been produced to ensure that the University complies with The Control of Substances Hazardous to Health (COSHH) Regulations 2005 and in accordance with HSE Guidance ‘Controlling Airborne Contaminants at Work – A Guide to Local Exhaust Ventilation, HSG 258.
