General ventilation

• All workplaces need an adequate supply of fresh air
• This can be natural ventilation, from doors, windows etc or controlled, where air is supplied and/or removed by a powered fan
• If you work in an office or shop, natural ventilation will normally be enough to control dusts and vapours from cleaning materials etc
• Sometimes planned, powered general ventilation is an integral part of a set of control measures, eg the welding of large fabrications in a workshop

Local exhaust ventilation

• Local exhaust ventilation (LEV), or extraction, is an engineering control solution to reduce exposures to dust, mist, fume, vapour or gas in a workplace
• Use a properly designed LEV system that will draw dust, fume, gases or vapour through a hood or booth away from the worker
• An extraction system should be easy for workers to use and enclose the process as much as possible
• It should effectively capture and contain the harmful substance before it is released into the working environment
• Air should be filtered and discharged to a safe place
• The system should be robust enough to withstand the process and work environment. It is important to maintain it and undertake tests to ensure it is working effectively
