Local Exhaust Ventilation in Schools

Local Exhaust Ventilation in Schools

HSE is aware of several concerns regarding poor ventilation leading to the build-up of fume within science facilities. 

The causes have included exhaust ducting from fume cabinets not being installed correctly or not being maintained and checked for continued
effectiveness.  Suitable thorough examination would have discovered the faults identified.

Schools and colleges should ensure that any extraction, or ‘local exhaust ventilation’ (LEV) functions correctly and adequately controls the risks. This
includes LEV used in connection with welding or woodworking equipment.

Guidance on LEV and how to maintain it can be found on the HSE website, click here  and for further guidance specifically relating to LEV in Science, Design and Technology is available from CLEAPSS and SSERC.
