Dust and fumes can enter the body through inhalation or skin contact, leading to occupational asthma, dermatitis, and other serious health conditions. A properly designed and maintained Local Exhaust Ventilation (LEV) system captures these contaminants before they reach your team.
Under COSHH regulations, employers must ensure every LEV system is tested and maintained regularly. If you employ five or more people, all tests must be documented and retained for at least five years.
Our qualified engineers complete hundreds of LEV Thorough Examinations and Tests (TExTs) each year across the UK, the statutory test required under COSHH regulations. Using precision instruments, we assess system performance and verify compliance with HSE guidance HSG258.


Only a competent engineer with relevant training, equipment, and experience can legally carry out a Thorough Examination and Test. Dustraction’s engineers are qualified specialists who follow HSE and COSHH guidance to ensure accurate results and reliable certification.


Visual inspection of hoods, ducts, filters, and fans


Airflow and capture efficiency testing against design standards


Exposure control checks to confirm contaminant capture


Comprehensive report and compliance certification


Maintenance and improvement recommendations
Each report conforms to HSE guidance HSG258, the COSHH Approved Code of Practice, and all current HSE legislation.
Alongside every COSHH / LEV test, Dustraction provides a mechanical service inspection to verify that your system’s components and control equipment are operating correctly.
This proactive approach reduces the risk of system failure, ensures consistent airflow, and keeps your workplace compliant and safe.


Over time, filters, ducts, and fans can become blocked, leakages can occur and resulting in degraded performance. Regular testing ensures your system continues to protect workers, maintains legal compliance, and prevents costly downtime.


Your COSHH documentation must be kept with your company records for a minimum of five years, and every system must be thoroughly examined and retested at least once every 14 months, or more frequently in high-risk environments.
All testing and documentation provided by Dustraction conform to HSE COSHH regulations, the COSHH Approved Codes of Practice, and HSG258: Controlling Airborne Contaminants at Work.
How often must I have my LEV system tested under COSHH?
Every 14 months, or more often in high-risk environments such as metal working or welding which is every 6 months.
What happens if my system fails the test?
We’ll identify the issue, provide clear recommendations, and support you through repairs and retesting.
Does Dustraction test third-party systems or only your own?
We test all extraction systems, regardless of manufacturer or installer.
What documentation will I receive?
You’ll receive a full report, schematic drawing, photos, performance data, certification of compliance, and any recommendations, all audit-ready.
How long do I need to keep records?
All COSHH / LEV test documentation should be retained for at least five years. These records prove your compliance with HSE requirements and must be available during audits or inspections.
