Local exhaust ventilation is a vital exposure control in most industrial workplaces.  The performance of the system is however critically dependent upon its design and upkeep.

Ethos Environmental Ltd bring an occupational hygiene perspective to the assessment of LEV systems, rather than viewing the problem as purely an engineering or technical issue. How easy is the LEV to use? Does the operator use the system properly?

Our experienced hygienists look at the system design as it applies to the specific process and tasks on-site, as well as testing the system's technical effectiveness (capture velocity, face velocity, duct velocity, pressure drop etc) as required under the COSHH Regulations.
