LEV Testing & Maintenance
Protecting air quality and ensuring compliance with COSHH regulations.
Workplace Air Quality Protection
Local Exhaust Ventilation (LEV) systems protect workers from hazardous fumes, dust, vapors, and airborne contaminants generated during industrial processes—meeting COSHH (Control of Substances Hazardous to Health) regulatory requirements.
Regular testing verifies LEV systems capture and remove contaminants effectively, preventing worker exposure that could cause respiratory disease, occupational illness, or long-term health consequences.
COSHH Testing Requirements
Testing Intervals
COSHH requires LEV testing at least every 14 months. High-risk processes require more frequent testing. New installations must be commissioned before use.
Hood Face Velocity Tests
Measure airflow at extraction hoods to verify performance meets design specifications and COSHH control requirements for specific contaminants.
Filter Checks
Inspect filter loading, pressure drop, and efficiency to ensure continued contaminant capture without excessive energy consumption or reduced performance.
Reporting
Comprehensive test certificates, performance comparison against baseline, identified defects, and remedial recommendations meeting HSG258 guidance standards.
Risks of Non-Compliant LEV Systems
Inadequate LEV systems expose organizations to:
Exposure to hazardous substances causes respiratory disease, occupational asthma, and long-term illness
Improvement or prohibition notices, prosecution, and unlimited fines for COSHH breaches
Employee litigation for exposure-related illness caused by inadequate workplace controls
Policies require documented compliance with health and safety legislation as a condition of cover
