LEV Testing

Local Exhaust Ventilation (LEV) testing is a legal requirement under the UK’s COSHH (Control of Substances Hazardous to Health) Regulations, designed to ensure that equipment controlling exposure to airborne contaminants—such as dust, fumes, oil mist, and smoke—is functioning effectively. These tests must be conducted at least once every 14 months by a competent person, in accordance with HSE guidance (HSG258).

• Visual inspection of the system to check for damage, wear, and cleanliness.
• Airflow and performance measurements to ensure the system is operating effectively.
• Examination of key components like filters, ducts, fans, and alarms for functionality.
• Assessment of control effectiveness to verify the system adequately protects workers from airborne contaminants.
