LEV Testing

What we do

We evaluate all types of LEV systems, including fixed and mobile extraction units, on-tool capture systems, booths, enclosures, and ducted installations. Each assessment includes thorough examination and testing using HSE-approved methods to ensure system performance and compliance.

Our consultants check airflow rates, static pressure, filter conditions, and overall capture efficiency. Every component is inspected, including hoods, ducts, filters, fans, and discharge points, to identify wear, inefficiency, or blockages.

We work with a broad range of sectors, including manufacturing, food processing, and laboratories. Our team assesses LEV systems used in processes like welding, grinding, paint spraying, and chemical handling. We tailor our approach to suit the specific contaminant type and exposure risk, and support single-site operations as well as multi-system industrial sites with complex extraction needs.

Why it matters

All assessments are conducted in accordance with COSHH Regulation 9, which mandates regular inspection (at least every 14 months), and HSG258 guidance, which defines how testing should be conducted, along with best practice in LEV system design and maintenance. We help ensure your systems remain compliant, effective, and fit for protecting the breathing air of your employees.

Validate Consulting is proud to cover everything from initial assessments and routine re-inspections to post-installation validation and system commissioning. Beyond basic compliance, we assess how efficiently your LEV systems protect workers. We identify where systems may be underperforming or at risk of failure, highlighting issues that could compromise health or cause operational downtime.

All assessments are carried out by our expertly trained Occupational Hygiene Consultants  (with a minimum of BOHS P601) with experience across multiple industries. All of our equipment used in testing is annually calibrated. We operate throughout the UK, offering both local and nationwide coverage.

What you receive

Each assessment results in a detailed report summarising test results, system performance, maintenance needs, and any non-compliance findings. Reports include system specific details, and recommendations for improving protection and health of workers.
