LEV from a Technical Perspective

A Local Exhaust Ventilation (LEV) system can help employers effectively control exposure to gas, vapour, dust, fumes and mist generated in the workplace by extracting the contaminant cloud before the workers breathe it in. An LEV system should be able to effectively capture fugitive hazardous substances, removing them from the workplace and thereby aiding in hazardous substance exposure control for the workers. SOCOTEC's Occupational Hygienist, Mary Cameron, discusses LEVs from a technical perspective.…

In the workplace, exposure to hazardous substances should either be prevented or adequately controlled. The purpose of an Local Exhaust Ventilation (LEV) system is to control the emission of such substances to the atmosphere as close as possible to the point of source, thereby preventing release into the workplace. To be effective, LEV must initially be well designed and constructed. Over time, the performance of systems can deteriorate due to wear, blockage or damage. Thus, regular inspection and testing is critical to ensure that control of exposure remains adequate, and this is one of the many occupational hygiene services that SOCOTEC provides. Here, David talks us through the process at a major railway maintenance depot.…
