Employers in the U.K. who produce, handle, or use hazardous substances—such as dusts, fumes, vapours, and mists—are legally required to comply with the Control of Substances Hazardous to Health (COSHH) Regulations 2002.
When exposure to these substances cannot be fully eliminated, it must be effectively controlled, with Local Exhaust Ventilation (LEV) systems serving as the primary engineering solution.
COSHH Regulation 9 outlines the legal duties for maintaining and testing these systems, with Regulation 9(2) setting a statutory maximum inspection interval of 14 months. Although this meets the minimum legal standard, industry best practice recommends annual (12-month) inspections to reduce risk.
Operating close to the 14-month limit increases the chance of system degradation—due to damage, filter loading, or material build-up—which can compromise airflow and control effectiveness well before the deadline.
