Local Exhaust Ventilation (LEV) workplace fume and dust extraction
Effective LEV or dust/fume extraction can carry away airborne contaminants before they can be breathed in.
This website provides practical advice for employers and employees on buying and using LEV and what to do to comply with the law. It will help designers, installers and examiners work with their customers to control airborne contaminants effectively.
The effective application of LEV requires a good understanding of processes and the dust sources they create.
Our series of downloadable videos of common processes demonstrate the dangers to be aware of when working with airborne dust.
