A Local Exhaust Ventilation (LEV) system is one of your key defences against hazardous airborne contaminants. To keep workers safe and stay compliant with COSHH Regulation 9, your LEV must undergo a Thorough Examination and Test (TExT) at least every 14 months or more often for high-risk processes.
Proper preparation ahead of the inspection helps ensure the process runs smoothly, reduces downtime, and makes it easier to prove compliance during audits.
Understand What the TExT Involves
According to HSG258 – Controlling airborne contaminants at work, a TExT is a detailed, statutory inspection that confirms:
- The system is functioning as intended
- Airflow and capture performance meet design specifications
- Key components are free of damage, wear, or blockages
- Records and logbooks are up to date
Knowing what the examiner will look for helps you prepare in advance.
Step 1 - Gather Your Documentation
Having the right information ready will speed up the process and ensure accuracy.
How to prepare:
- The LEV logbook with daily/weekly/monthly checks recorded
- Design or commissioning data, including airflow benchmarks
- Previous TExT reports to compare performance over time
- Records of maintenance and repairs
These documents help the competent person evaluate whether your system still controls exposure effectively.
Step 2 – Carry Out Basic System Checks
Before the inspection, HSG258 recommends routine checks to ensure there are no obvious issues that could delay testing:
- Visually inspect hoods, ducts, and filters for signs of damage or blockage
- Check airflow indicators and pressure gauges for abnormal readings
- Listen for unusual noises or vibrations that could indicate faults
- Ensure the system is clean and accessible for testing
Step 3 – Plan for Access and Scheduling
Testing requires access to key parts of the LEV system. To prepare:
- Clear any obstructions around hoods, ducts, and fans
- Inform staff of the testing schedule to minimise disruption
- Allow enough time for the engineer to complete airflow and performance measurements safely

Step 4 - Engage Your Team and Review Training
The TExT visit is a good time to refresh staff knowledge. HSE recommends:
- Reviewing the user checklist for daily/weekly checks
- Ensuring operators understand how to spot problems early
- Updating any training records to demonstrate competence
Step 5 – After the Test: Records and Action
Once the TExT is complete, you should receive:
- A written report of the examination and test
- Any recommendations for repairs, adjustments, or additional checks
- Clear evidence to file in your records, which must be kept for at least five years
Acting promptly on recommendations helps maintain compliance and keeps your workforce safe.
