Local Exhaust Ventilation Testing
Local Exhaust Ventilation (LEV) is commonly used to control the release of hazardous airborne substances from a process into the workplace environment. The object of LEV is to control the emission at the point of release and prevent it from entering the air of the workplace.
A typical LEV system works by drawing contaminated air from the process through a partial enclosure or hood at, or close to, the source of emission. The contaminated air is then cleaned and discharged externally or recalculated into the room, preferably via a secondary filter.
An effective LEV system should be well designed and constructed, properly used and maintained in good condition, with regular inspections.
A system is deemed to be LEV if it is used to control, capture or contain airborne releases on, at, or close to the point of emission and then convey them to a point where they can be collected or released.
The control of Substances Hazardous to Health Regulations (COSHH) Regulation 7, requires that the exposure of employees to substances hazardous to health be prevented or if this is not practicable, adequately controlled. Regulation 9 requires all control measures to be properly maintained and regularly examined and tested. The employer should ensure all control measures are maintained in an efficient state, good working order and in good repair.
