This image shows a LEV (Local Exhaust Ventilation) competency matrix created by the LEV Industry Forum Competency Working Group. It outlines the essential and desirable knowledge required for different LEV roles, including employers, designers, installers, examiners, and managers.
The matrix links LEV topics (such as system design, installation, testing, maintenance, and health & safety) with competency levels, showing how much understanding each role needs. It also maps these requirements to training courses, guidance documents, and recognised qualifications.
Overall, the document is used as a standard reference to assess competence, identify training needs, and ensure LEV work is carried out safely, consistently, and in compliance with regulations.
