Local Exhaust Ventilation Testing (LEV)

What Is Local Exhaust Ventilation?

Local Exhaust Ventilation (LEV) is an engineering control system used to reduce exposure to airborne contaminants in a workplace by capturing and extracting the contaminant at the source of the emission.

It is the employer’s responsibility to ensure that exposure is reduced to levels as low as is reasonably practicable. In many cases, LEV is the solution.

LEV Testing

How Often Do I Need Local Exhaust Ventilation Testing?

As LEV is a control measure under the The Control of Substances Hazardous to Health (COSHH) Regulations it must be regularly and thoroughly inspected and tested and states that any employer who uses Local Exhaust Ventilation to control hazardous substances, must ensure that it is operating effectively.

For most systems, the maximum time between tests is no longer than 14 months. But certain LEV systems, require more frequent inspection (stated in the Regulations) in order to meet this legislation, and visual inspection of the system to ensure integrity.

 

What Does An LEV Test Consists Of?

System performance data will be obtained on static pressure, transport and face velocities, capture design and practical use.

The other important part of the LEV Test is a qualitative assessment on the control of potential contaminants by smoke testing. Measurements obtained are compared with the available original Local Exhaust Ventilation specification and the relevant performance criteria given in HS(G)258.

In addition to examining and testing the LEV, Envirocare provides records as specified in HS(G)258 ‘Controlling Airborne Contaminants at Work – A Guide to Local Exhaust Ventilation’ (HSE, 2008). In doing so, the record will provide evidence in fulfilling the requirements of Regulation 9 of COSHH guidance. Our reports will also assist you in improving these control measures where necessary.
