LEV Testing Service

Dustcheck provides a range of LEV Testing service packages, ensuring your business complies with LEV and environmental regulations.

Legal Requirements

  • Local Exhaust Ventilation (LEV) Thorough Examination and Test in line with HSG 258 – Controlling airborne contaminants at work.
  • The Health and Safety at Work act, Control of Substances Hazardous to Health Regulations (COSHH) and the Management of Health and Safety at Work Regulations all place a legal requirement on owners of LEV systems to ensure that they are controlling the operator’s exposure.
  • The thorough examination and test forms part of this legislation requirement where HSG 258 Controlling airborne contaminants at work provides guidance on the minimum requirements.

The content of the Local Exhaust Ventilation (LEV) Thorough Examination and Test is individual to each system installation and we therefore tailor our service to give the most cost effective solution for the client.

The frequency of the thorough examination and test is dependent on the process and can vary from 1 month to a maximum of 14 months. Dustcheck recommend a 12 month period.

To enable a LEV Testing to take place the system(s) needs to be documented, this requires the following:

  1. A LEV user manual
  2. A system logbook
  3. Suitable commissioning report or previous thorough examination and test report

If the above items are not available it is not possible to complete a thorough examination and test since the existing system is considered undocumented. If the system is found to be undocumented then it is possible that this examination could carry out additional work to document and support future thorough examinations and tests.
