Safety of machinery - Local exhaust ventilation system - Safety requirements
1 Scope
This standard specifies the basic safety requirements for local exhaust ventilation (LEV) system.
This standard is applicable to the fixed industrial local exhaust ventilation (LEV) system for preventing or avoiding personnel from contacting airborne harmful substances in the industrial environment.
This standard is not applicable to the local exhaust ventilation (LEV) systems for the following purposes:
——comfortable ventilation;
——conveying air as a part of industrial process;
——painted cabinets not mainly for protecting personnel;
——saving energy;
——special use, special cleaning and special protection requirements.
