Local Exhaust Ventilation (LEV) system is a workplace engineering control system that help to extract airborne chemical hazardous to health out of workplace environment. The effectiveness and efficiency of this ventilation system is critical prevent working personnel expose to hazardous chemical during working.

Local Exhaust Ventilation (LEV) system Inspection, Testing and Examination need to be carried at interval of not more than 12 months. Employer need to appoint Hygiene Technician II registered with Department of Occupational Safety and Health (DOSH) to perform LEV testing and examination in order to comply with Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulation 2000.
