LEV Testing

Local Exhaust Ventilation (LEV) Assessments

Throughout Kent, London, Essex, Sussex and Surrey

Our LEV assessments are carried out in line with the recommendations of HSE’s HSG258 (2011) Controlling Airborne Contaminants at Work, COSHH Regulations and The Health & Safety at Work Act.

What you need to know

  • Every employer’s LEV system requires statutory ‘thorough examination and testing’ by a competent person.
  • The examination and testing report should have a prioritised list of any remedial actions for the employer.
  • The employer’s engineer and person responsible for health and safety both need to see the report.

What is Local Exhaust Ventilation (LEV)?

LEV is an engineering control system to reduce exposures to airborne contaminants such as dust, mist, fume, vapour or gas in a workplace. Most systems, but not all, have the following:

  • Hood: This is where the contaminant cloud enters the LEV.
  • Ducting: This conducts air and the contaminant from the hood to the discharge point.
  • Air cleaner or arrestor: This filters or cleans the extracted air. Not all systems need air cleaning.
  • Air mover: The ‘engine’ that powers the extraction system, usually a fan.
  • Discharge: This releases the extracted air to a safe place.

Legal responsibilities

  • The employer of the people being protected by the LEV has legal responsibilities under the Health and Safety at Work etc Act 1974, the Control of Substances Hazardous to Health Regulations (COSHH) 2002 (as amended) and the Management of Health and Safety at Work Regulations 1999 (MHSWR).
  • LEV suppliers have legal responsibilities under the Health and Safety at Work Act 1974; the Supply of Machinery (Safety) Regulations 2008 (SMSR), including ‘essential health and safety requirements’.
  • Service providers have legal responsibilities under the Health and Safety at Work etc Act 1974 and the Construction (Design and Management) Regulations 2007.

Airborne Contaminants

Airborne contaminants are particles, gases or vapours and combinations of these. ‘Particles’ include dusts, fumes, mists and fibres.

Thorough examination and test

Our thorough examination and test is a detailed and systematic examination sufficient to ensure that the LEV can continue to perform as intended by design and will contribute to the adequate control of exposure. This thorough examination includes functional testing to provide sufficient evidence to indicate adequate control is being achieved.
