LEV TESTING TO ACHIEVE COMPLIANCE

Local Exhaust Ventilation (LEV) systems are used across a wide range of industries to remove airborne contaminants before they can be inhaled. These contaminants may include dust (such as flour dust in bakeries), mist (for example, paint mist from spraying), fumes (e.g. welding), vapour, gases or other hazardous airborne substances.

Every year, thousands of employees in Great Britain develop lung disease or occupational asthma due to exposure to airborne contaminants at work. LEV systems form a critical part of controlling these risks, but only when they are correctly installed, used, maintained and regularly tested.

For LEV to work effectively, it must be the right type, properly installed, used and maintained. Under the Control of Substances Hazardous to Health Regulations 2002 (COSHH), LEV systems must undergo Thorough Examination & Testing at least every 14 months. Where wear, heavy use or environmental conditions could reduce system performance sooner, more frequent LEV inspections are required.

Frequently Asked Questions (FAQS)

What is a LEV test?

A LEV test (Thorough Examination & Test) is a legally required inspection that assesses how effectively a Local Exhaust Ventilation system controls airborne contaminants. It includes airflow measurements, visual checks, performance verification and a detailed report.
How often should LEV be tested?

Under COSHH, LEV systems must be tested at least every 14 months. Systems exposed to heavy use or harsh conditions may require more frequent inspections.
Can I do my own LEV testing?

No. LEV tests must be carried out by a competent person with specialist knowledge of airflow, contaminant control and COSHH compliance. Independent UKAS-accredited inspectors provide the highest level of assurance.
