Local Exhaust Ventilation (LEV) Testing Services


LEV systems must be examined and tested every 14 months under (HSE) Health & Safety Guidelines.

What is Local Exhaust Ventilation (LEV)?
Each year thousands of workers in the UK develop illnesses such as lung disease, cancer and other complications as a result of exposure to airborne contaminates whilst at work. Any work that produces a dust, mist, fume, gas or vapour could be a substance hazardous to health and cause unnecessary risk to an employee’s health.

Employers are often unaware that their employees might be overexposed to potentially harmful airborne substances. This is contributed to by a number of factors, including inaccurate identification of the source of exposure, controls not being correctly used or the owner/manager being over optimistic about the effectiveness of their current controls.

A LEV system is an engineered solution specifically designed to capture and control any airborne substance before it can become inhalable and potentially harmful to the user. By means of appropriate extraction methods a LEV system provides control measures in the workplace preventing diseases and conditions occurring later in life.

Types of LEV equipment:

  • Fume Cupboard
  • Partial Enclosure Booth
  • Extraction Canopy Hood
  • On Tool Extraction
  • Laminar Flow Cabinets
  • Capture & Receptor Hoods

LEV is a way of controlling and reducing the exposure of workers to airborne containments which could be hazardous to their health. For example, a manufacturing process may have localised extraction hoods connected with ductwork to a fan and filter which transports contaminated air away from the workers before discharging it into the atmosphere.

Typical industries and activities where the control of airborne hazardous substances maybe needed:

  • Saw mills and joinery
  • Welding and sheet metal work
  • Stone-masonry
  • Manufacturing environments
  • Factories
  • Laboratories and chemical handling
  • Schools, Colleges and Universities
  • Garages
  • Paint-spraying and powder coating
  • Engineering
  • Bakery and food manufacture
  • Plating and metal treatment facilities
  • CNC machining
  • Grinding, finishing and polishing
  • Fabric and material manufacture
