Local Exhaust Ventilation (LEV)

The definition of a local exhaust ventilation (LEV) system is: an engineering control system to reduce exposures to airborne contaminants such as dust, mist, fume, vapour or gas in the workplace. Simply put it is something that sucks an airborne contaminant out of the workplace.

It is vital that the correct LEV is chosen for a particular task and kept correctly maintaied. If a process or activity with which the LEV is associated is changed then the suitability and specification of the LEV system must be re-assessed.
