LEV System Testing and Appraisal
Work processes which result in dust and fume emissions can cause health disorders such as occupational asthma, respiratory disorders and even cancer. The COSHH Regulations 2002 require that exposure to such substances must either be avoided completely or adequately controlled where this is not practicable. Local Exhaust Ventilation (LEV) Extraction Systems are designed to remove contaminants at or close to the point of emission.
Employers using LEV systems are legally obliged to ensure that they are inspected and tested at least once every 14 months or even more frequently for certain applications (refer to table shown below).
