LEV/Fume Extraction equipment


In many work activities, substances that are hazardous to health are handled, produced or processed in ways that result in dust, fumes or gases being emitted to the workplace atmosphere.  Local Exhaust Ventilation (LEV) has an important place in the hierarchy of control measures.  The aim of thorough LEV examination is to provide an independent assessment ensuring hazard control and engineering performance.  Under the HSA guidance on Local Exhaust Ventilation (LEV) it is recommended that a thorough examination is carried out at least every 14 months.  Examples of LEV systems include:

  • Fume Cupboards
  • Nederman arms
  • Dust extraction systems
