Local Exhaust Ventilation Testing

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


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.


Dukeries Environmental Testing are specialists in providing comprehensive Local Exhaust Ventilation (LEV) testing services to employers who use LEV to control dust, fumes and airborne contaminations, ensuring workers are kept in a safe environment.

All of our test and examination of LEV systems fulfils the requirements of the COSHH Regulations 2002 and the HSE Guidance Note HS(G)258 “The maintenance, examination and testing of local exhaust ventilation.” including measurements of static pressure, transport velocity, and face velocity. All test reports clearly show test data along with any repairs undertaken and recommendations in order to ensure the systems’ continued effectiveness.


Dukeries Environmental Testing staff are vastly experienced in testing all types of LEV systems including those within Schools, Pharmaceutical Companies, Hospitals, Chemical Plants, Engineering Workshops and Joinery Shops.
