OSHA Technical Manual (OTM) - Section III: Chapter 3
A typical local exhaust ventilation system is composed of five parts: fans, hoods, ducts, air cleaners, and stacks. Local exhaust ventilation is designed to capture an emitted contaminant at or near its source, before the contaminant has a chance to disperse into the workplace air.
Local Exhaust Ventilation: A Comprehensive Guide - SafetyCulture
2024年8月1日 · Local Exhaust Ventilation (LEV) is an engineering control system used to capture and remove airborne contaminants at their source before they can spread throughout the site. It’s an essential part of workplace health and safety programs, as it aims to protect workers from exposure to hazardous dust, mist, vapor, and fumes.

The New Standard for Local Exhaust Ventilation - The Synergist
Where tools, processes, or equipment generate different dusts, fumes, or vapors which could, if intermixed, result in a realistic health or explosion hazard, or corrosion, such contaminants shall be exhausted by separate exhaust ventilation systems.
Local exhaust ventilation - WorkSafe
Local exhaust ventilation is an engineering system that captures dust, vapours, and fumes at their source, minimising the risk of workers breathing in contaminated air. There are also other mechanisms for different ventilation requirements, such as: general exhaust ventilation (GEV) industrial vacuums.
Mastering Industrial Air Quality with Local Exhaust Ventilation …
2024年8月22日 · Local Exhaust Ventilation (LEV) systems are sophisticated engineering controls designed to mitigate workplace exposure to hazardous substances. By capturing emissions at the source, LEV systems play a crucial role in maintaining a safe and …
Local Exhaust Ventilation (LEV) sometimes referred to as a snorkel or elephant trunk is an engineering control used to capture low risk airborne contaminates at or near the source and remove them away
Local Exhaust Ventilation - an overview | ScienceDirect Topics
Local exhaust ventilation involves the capture of air contaminants at a source. A local exhaust ventilation system consists of a hood or enclosure to capture a contaminant, an air pollution control device to clean the air, and an air mover to provide air flow through the system.
