Local Exhaust Ventillation (LEV)

Testing & Inspection

The function of LEV systems is to capture pollutants at source and control exposure.

The COSHH Regulations impose a duty to ensure that all LEV systems must be inspected & tested by a competent person at least every 14 months.

At Anchem Laboratories, we offer thorough and reliable testing and inspection of Local Exhaust Ventilation (LEV) systems to help you maintain a safe and healthy working environment. .

LEV systems are designed to capture harmful dusts, fumes, and vapours right at the source, protecting your team from exposure to airborne contaminants. Regular inspection and testing isn’t just good practice, it’s a legal requirement under workplace health regulations.

Our experienced team carries out detailed assessments in line with official guidance to make sure your systems are working effectively.

This includes measuring air movement (such as capture and face velocities), checking for wear and tear, and making sure all parts, from enclosures to extraction hoods, are functioning properly. We also inspect filters, fans, and other control components to ensure your whole system is running as it should.

  • LEV inspections as required under COSHH regulation 9 ‘Maintenance Examination & Testing of Control Measures’
  • Inspections in accordance with HSG258 “Controlling airborne contaminants at work”
  • Capture velocities, face velocities, duct (transport) velocities & static pressure readings
  • Thorough examination of all system parts for wear & tear. Solid ductwork, flexi hoses, seals, dampers
  • Examination of full enclosures (containment), partial enclosures (spray booths, fume cupboards), receiver hoods (grinding, canopy), capture hoods (welding, soldering, lip extraction, downdraught tables)
  • Checks on abatements – fans, filters, wet arrestors, self cleaning systems (shake down, air jet pulse)
  • Comparison of data with commissioning reports, user manuals, logbooks or previous test reports
