What qualifications should an LEV testing engineer hold?

An LEV testing engineer should hold recognised training and competency specific to local exhaust ventilation testing, not just general engineering experience. In the UK, this typically means completing accredited LEV examination and testing courses that cover airflow measurement, hood performance, and system evaluation.

Competent engineers understand how LEV systems are meant to control exposure, not just how to take readings. They should be familiar with relevant legislation, including the Health and Safety Executive guidance and COSHH requirements, and be able to interpret results properly.

Membership of professional bodies or certification schemes can be a good indicator, though it’s not mandatory on its own. Experience also matters. An engineer who regularly tests systems across different industries is more likely to spot design flaws or gradual performance decline.

Ultimately, competence is about training, experience, and understanding exposure control, not just owning test equipment.
