Definition
“LEV (Local Exhaust Ventilation) is an engineering control system to reduce exposures
to airborne contaminants such as dust, mist, fume, vapour, or gas in a workplace”
(HSE 2011).
Statutory Examination and Testing
Every LEV system requires statutory thorough examination and testing by a competent person under the
Control of Substances Hazardous to Health (COSHH) Regulations: 2002 (amended 2004). The maximum
time between tests of LEV systems is 14 months. In practice this is normally taken to mean annually.
The examiner should:
• Carry out a thorough external examination of all parts of the system for damage, wear and tear.
• Measure the air velocities at suitable test points indicated in the system documentation.
• Measure static pressure at suitable test points indicated in the system documentation.
• Observe processes and sources and assess how effective the LEV is at controlling operators’ exposure.
When testing hoods, the examiner will attach a test label to each hood tested. A red ‘fail’ label could be
attached for the following reasons:
• No airflow.
• Failure of the hood to intercept or contain the contaminant cloud.
• The hood capture zone does not encompass the working zone.
The examiner will compare the test information against the original commissioning report, or previous
test reports, to determine system effectiveness. A full report for each LEV system will be produced by the
examiner. If required, the LEV report will highlight any minor adjustments or repairs required to make the
LEV system effective.
Filtermist -JNJUFE is able to provide LEV testing to HSG258 standards. For a quotation, contact the
