Local Exhaust Ventilation (LEV) Regulations and Testing
Local Exhaust Ventilation (LEV) system can remove airborne contaminants such as dust, mist, gas, vapour or fumes before people breathe them
in and will protect workers’ health.
What Is Local Exhaust Ventilation?
Local Exhaust Ventilation (LEV) is an engineering control system used to reduce exposure to airborne contaminants in a workplace by capturing and extracting the contaminant at the source of the emission.
Helping you meet COSHH regulations
Local exhaust ventilation (LEV) systems are commonly used as an engineering control measure to capture and transport harmful substances released from a process at source, before entering the workplace atmosphere.
The Control of Substances Hazardous to Health (COSHH) Regulations 2002 places a duty on the operator to ensure that all control systems, including LEV, are tested by a competent person and inspected at least once every 12 months, or more frequently for some processes.
Under the Health and Safety Executive, Controlling airborne contaminants at work – A guide to local exhaust ventilation (LEV), HSG 258, it is the employer’s responsibility to know and understand the following:
