What is Local Exhaust Ventilation testing (COSHH LEV Testing)?

COSHH LEV Testing is a quantitative test that measures whether your dust, vapour, gas or fume extraction system is providing adequate control of the hazards created by your processes. 

Why does LEV need a Thorough Examination and Test and how often?

As stipulated by COSHH Regulation 9(2), an employer shall ensure that a LEV Thorough Examination and Test of the plant is carried out at least once every 14 months, sometimes more regularly, dependent upon application.  This will confirm for you whether or not your LEV system (Local Exhaust Ventilation)  is providing sufficient protection for workers or operators.
