Local Exhaust Ventilation Testing


Know the Risks

Every year, thousands of workers in Britain develop occupational diseases from breathing in certain dusts, fumes or other airborne contaminants at work.

Know the Law

The COSHH Regulations 2002 require that Local Exhaust Ventilation (LEV) systems are thoroughly examined and tested at least every 14 months, more regular for some substances and processes.
