Local Exhaust Ventilation (LEV)
LEV is an engineering system designed to reduce employee exposure to airborne contaminants (dust, mist, fume, vapour, gas) in the workplace by capturing the emission at source and transporting it to a safe emission point or to a filter/scrubber.
A properly designed, maintained and operated local exhaust ventilation (LEV) system can remove airborne contaminants before people breathe them in and will protect workers’ health.
LEV systems must be tested every 14 months.
Regular LEV testing by a competent person is a legal requirement of COSHH (Control of Substances Hazardous to Health) regulations. This applies to all oil mist, welding fume, smoke and dust extraction units that you currently have on site.
An LEV test involves examining your equipment – including hoods, filters, and ducts – to measure the technical performance of your LEV system. Our experts will also assess whether your fume extraction system is the most effective extractor for your facility.
