LEV testing: what COSHH requires
LEV testing
If you use local exhaust ventilation to control exposure to hazardous substances, COSHH requires it to be maintained and thoroughly examined and tested, at least every 14 months under COSHH regulation 9 (more often for some processes), with records kept for at least five years.
What is LEV?
Extraction that captures dust, fume, vapour or mist at the source, such as welding arms, booths and hoods.
What does a thorough examination involve?
A visual inspection and measurements of airflow, capture and pressures, compared with the commissioning benchmark.
Who can test LEV?
A competent person; many testers hold the BOHS P601 qualification.
What should operators check day to day?
Simple user checks such as airflow indicators and visible capture, as set out in the system's logbook.
What is HSG258?
HSE's guidance on controlling airborne contaminants at work, covering LEV design, commissioning and testing.
