Local Exhaust Ventilation (LEV) systems serve as a crucial engineering control to minimise occupational exposure to harmful airborne contaminants. Throughout industrial and commercial processes, fumes, dust, vapours, and mists are generated, often posing significant health risks to the workforce. LEV systems operate by capturing contaminated air at the emission source, preventing its dispersion into the operator's breathing zone or the surrounding environment. This captured air is then safely removed or filtered to ensure that contaminants are effectively eliminated.
Properly functioning LEV systems not only contribute to a safer workplace but also help businesses meet health and safety regulations, particularly in industries where the control of hazardous substances is vital. Regular LEV testing ensures the system functions like a well-oiled machine, maintaining optimal air quality and protecting both operators and those nearby.
Why LEV Inspection and Certification Matters
LEV inspection and certification is not just a regulatory requirement—it’s a vital safeguard for your workforce and operational integrity. Here’s why regular LEV inspection and certification should be a priority for your business:
Identifies performance issues before they become health hazards
CHAS accreditation
Demonstrates corporate responsibility and commitment to employee safety
Provides peace of mind with expert-led evaluations and clear reporting
Validates system design and installation against current best practices
Enables proactive maintenance planning based on real-time performance data
Enhances trust with stakeholders through transparent safety protocols

Frequently Asked Questions
How often should LEV testing be carried out?
LEV systems should be tested at least every 14 months, as required by COSHH regulations, to ensure they continue to protect workers from hazardous substances. In high-risk environments—such as those with heavy particulate generation or chemical exposure—more frequent inspections may be advisable. Regular testing not only ensures early detection of faults but also supports consistent system performance, legal compliance, and employee safety.
How long does an LEV inspection usually take?
The duration of an LEV inspection depends on the size and complexity of your system. A straightforward setup may take only a couple of hours, while larger, multi-point systems can require a full day or more. We always provide clear timelines in advance and work efficiently to minimise disruption to your operations.
Is LEV testing disruptive to daily operations?
Our team works efficiently to minimise disruption during inspections. Most testing can be completed without halting production. We coordinate with your team to schedule inspections at convenient times and ensure a smooth process.
What industries benefit most from LEV testing?
Industries such as welding, woodworking, chemical processing, and food manufacturing rely heavily on LEV systems. These environments generate airborne contaminants that pose serious health risks. LEV testing helps control exposure and maintain regulatory compliance.
How do I know if my workplace needs LEV testing?
If your operations generate airborne contaminants such as dust, fumes, vapours, or gases, LEV testing is likely required under COSHH regulations. We can assess your site and advise whether LEV inspection and certification is necessary to maintain compliance and protect your workforce.
