LEV Testing

If you have local exhaust ventilation (LEV) systems, be they spray booths, welding hoods, exhaust slots on degreasing-baths or larger multi-point systems, the law says they must be thoroughly examined and tested at least every 14 months.

Typical test parameters:

  • Visual inspection for damage or corrosion
  • Pressure drop across fan
  • Pressure drop across bag filters or other arrestment plant
  • Pressure behind exhaust hoods
  • Air flow rate through main system and branch ducts
  • Air flow rate at booth face, or in front of exhaust hood
  • Visualisation of air flow characteristics at contamination source or containment interface

Information provided by the examination & test:

  • Is the systemikely to provide adequate control & containment?
  • Does the system meet minimum standards of effective design and performance?
  • Has there been any change in performance since the previous test?
  • What action is necessary to achieve satisfactory performance?
  • What maintenance/repairs will be needed to prevent forseeable loss of efficiency?
  • Records must be kept 5 years
  • HSE inspectors will always want to see them
  • An essential element in defending compensation litigation
