Local Exhaust Ventilation

Under the COSHH (Control of Substances Hazardous to Health) regulations there is a duty on employers and employees to ensure that exposure to hazardous substances is prevented or otherwise adequately controlled.

HSG258 was published in 2008 and contains information about: the roles and legal responsibilities of suppliers and employers; competence; principles of good design practice for LEV hoods and their classification; ducts, air movers, air cleaners; and system documentation.

In the case of operations that produce dust and fumes, Local Exhaust Ventilation (LEV) is a very common control method. LEV systems capture and remove air contaminants at the point they are being produced before they escape into the workplace and take various forms including :

  • Extracted workstations
  • Mobile extraction points
  • Fume hoods / cupboards / cabinets
  • Spray booths

Companies must endeavor to ensure their LEV systems are maintained in good working order at all times, and also have the statutory Thorough Examination and Testing (TExT) of LEV systems carried out as required by the COSHH Regulations. Cti can undertake the TExT surveys, which would either declare them in good working order, or indicate any issues with each system. Cti also has the technical expertise trouble shooting should any system have serious issues.
