Key Points

  • Every employer’s LEV system requires a 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 the person responsible for health and safety both need to see the report.

A thorough examination and test (aka LEV COSHH 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. The thorough examination would typically include functional testing to provide sufficient evidence that adequate control is being achieved. The comprehensive examination and test must be conducted by a competent person who can provide an objective assessment of the LEV.

The maximum time between LEV tests is 14 months. In practice, this is usually taken to mean annually. If wear and tear on the LEV system is likely to degrade the system’s effectiveness between tests, then thorough examinations and tests should be more frequent.

A thorough examination and testing of the LEV will comprise three stages.

  • Stage 1 – A thorough visual examination to verify the LEV is in efficient working order, in good repair and clean condition.
  • Stage 2 – Measuring and examining the technical performance to check conformity with commissioning or other sources of relevant information.
  • Stage 3 – Assessment to check the control of worker exposure is adequate.
