LEV Thorough Examination and Test (TExT)
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 LEV Thorough Examination and Test (TExT) at least every 14 months or more often for high-risk processes.
Proper preparation ahead of the LEV thorough examination and test helps ensure the process runs smoothly, reduces downtime, and makes it easier to prove compliance during audits.
Understand What the LEV thorough examination and test (TExT) Involves
According to HSG258 – Controlling airborne contaminants at work, a LEV thorough examination and test (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 during the LEV thorough examination helps you prepare in advance.

HSG258 recommends routine checks before your LEV thorough examination and test
Prepare for your LEV Thorough Examination
Step 1 - Gather Your Documentation
Having the right information ready for the LEV thorough examination 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 completing the LEV thorough examination evaluate whether your system still controls exposure effectively.
Step 2 – Carry Out Basic System Checks
Before the LEV thorough examination, HSG258 recommends routine checks to ensure there are no obvious issues that could delay testing, these include:
- 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
LEV thorough examination and 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 LEV thorough examination (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 LEV thorough examination (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.
