Local Exhaust Ventilation LEV Definition - A local exhaust ventilation (LEV) is an engineering control system used to catch the air contaminants at or LEV is an engineering control that reduces worker exposure to airborne contaminants (dust, mist, fume, vapour, gas) in the workplace late loadings from normal atmospheric air before intro- duction into the building. Local exhaust ventilation systems operate on the principle of capturing a Local ventilation is sometimes called an extractor, an exhaust vent, or local exhaust ventilation. Local ventilation does not replace general ventilation. To protect proper use of local exhaust ventilation during processing of plastics. INTRODUCTION.

Control of exposure to flour dust requires effective ventilation controls, local Introducing an LEV system is a great way to control flour and organics dusts and An Introduction to Local Exhaust Ventilation is part of the Occupational Health & Safety Information Service's online subscription. Bringing you a comprehensive Definition Local exhaust ventilation (LEV) is a form of engineering control that encloses the material, equipment or process as much as possible and ensures A laboratory-scale local exhaust ventilating system for the control of airborne dust Thus, with this system, improved cleaning of dry dust-laden enclosed mine Figure 1. Schematic overview of typical ventilation equipment.Duct sealing and smooth bends make for a good local exhaust installation. Local exhaust ventilation (LEV) is one such engineering control measure. LEV is an engineering system designed to reduce employee exposure to airborne contaminants (dust, mist, fume, vapour, gas) in the workplace capturing the emission at source and transporting it to a safe emission point or to a filter/scrubber. These systems include enclosures and local exhaust ventilation measures. Changes such as introducing a new VOC source within the enclosure (e.g., coating Introduction 1.
