LEV Testing
Qualified LEV testing for COSHH compliance, clear reports, remedial guidance.
What Is LEV Testing?
LEV Testing (Local Exhaust Ventilation Testing) is a critical health and safety procedure that ensures workplace ventilation systems are effectively controlling employee exposure to hazardous airborne substances such as dust, fumes, vapours, smoke, oil mist, and wood particles.
- It performs as originally designed (matching the commissioning report).
- It effectively controls worker exposure to harmful airborne contaminants.
- It complies with HSE (Health and Safety Executive) guidelines and industry standards.

What’s Included in an LEV Test?
A comprehensive LEV test typically includes...
Airflow and pressure measurements to check extraction efficiency.
Ductwork integrity checks for blockages or leaks.
Filter condition inspection and assessment.
Capture and face velocity checks at hoods and extraction points.
Smoke tests or visualisation (where applicable) to observe airflow patterns.
Thorough visual inspections of all components (hoods, filters, ducts, fans).
Examination of wear and damage that may affect performance.
Comparison with design specifications and control benchmarks.

Legal Requirements
Under the COSHH Regulations (Control of Substances Hazardous to Health)
Most LEV systems must be tested at least once every 14 months.
Employers must keep LEV test reports for at least 5 years.
In higher-risk environments (e.g. metalwork, wood dust), more frequent testing may be recommended.
Why LEV Testing Matters
According to HSE:
Around 12,000 lung disease deaths each year are linked to past workplace exposures.
Proper LEV system maintenance and testing is a legal and ethical responsibility for employers.
Non-compliance can lead to fines, employee illness, and legal action.
