Local Exhaust Ventilation System For Welding

A typical local exhaust ventilation system is composed of five parts.

Local exhaust ventilation system for welding. These health effects carry short and long term implications. The mobiflex 200 m and 400 ms are low vacuum systems for welding fume extraction and filtration. A well designed welding helmet can help reduce a welder s exposure to welding fumes by diverting the plume away from the welder s breathing zone. Local exhaust ventilation lev is always the preferred method of removing welding fumes and gases.

Local exhaust ventilation lev is a well known engineering control for welding fumes but has not been adopted widely in the construction industry. Given that the vast majority of the respirable particles in the airstream are under 4 microns in size a filtered ventilation system that can filter down to that level is what is required to ensure the safety and health of the welder. This literature review presents data on the performance of a variety of lev systems for welding fume control from the construction five references shipyard five references and other industries. Local exhaust ventilation lev is an engineering control commonly used to control the risks to workers health from welding fumes.

When designed used and maintained properly it is an effective control measure. Local exhaust ventilation lev is one such engineering control measure. Local exhaust ventilation systems. Their size and mobility make them ideal for smaller manufacturing facilities.

The statiflex 200 m 200 m dual arm and 400 ms are stationary wall mounted low vacuum systems intended for light to medium duty extraction and filtration of welding fume. 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. This fact sheet provides information on some of the health risks associated with welding lev systems used for welding and their limitations. It exhausts or removes the toxic gases fumes dusts and vapours before they can mix with the room air.
