How to control airborne gas, vapour, dust, fumes and mist by LEV means, so extracting clouds of contaminant prior to breathing. Lists principles and good practice on the design, installation, commissioning and testing of cost-effective ventilation controls.

Addressed as much to suppliers of LEV goods and services – who need to advise clients about necessary and appropriate controls – as it is to employers and managers at the user end.

A thorough examination of the subject, which acknowledges that often employers are simply unaware that employees are over-exposed to substances or that existing controls may be inadequate, the guide seeks to pre-empt probable scenarios such as the possibility that sources of contamination may be genuinely missed, that LEV users (and suppliers) may be over-optimistic about effectiveness or that equipment control may have deteriorated unknowingly.
