LEV Inspection Checklist

LEV Inspection Checklist to assess local exhaust ventilation systems, including weekly/monthly visual checks and periodic thorough examination and test (TExT).

1. Is the LEV system ID clearly marked?

2. Is the LEV “tested” label present and within date (≤14 months)?

3. Is the system switched on and operational during inspection?

4. Is the airflow indicator fitted and working?

5. Are operating instructions/warning signs visible and legible?

1. Is the LEV switched on when the process is in use?

2. Is the extraction positioned close enough to capture contaminants effectively?

3. Is the hood or enclosure free from obstruction?

4. Is the airflow indicator showing correct performance?

5. Are there no unusual noises, vibrations, or odours?

6. Is there no visible dust, mist, fume, or residue escaping?

7. Is the work area clean and tidy, with waste containers not overflowing?

8. Are filters, grilles, or shakers in good working order?

9. Are flexible hoses, ducting, and visible cables free from damage?

10. Are monthly checks (LEV label in date, filters changed if needed) up to date?

1. Are all hoods free from damage, corrosion, or poor positioning?

2. Are all dampers operational and correctly positioned?

3. Is ducting intact, free from leaks, corrosion, or blockages?

4. Are inspection hatches sealed and secure?

5. Is the air cleaner/filter fitted correctly, free from clogging or saturation?

6. Has the dust/fines collection bin been emptied?

7. Is the fan secure, free from damage, and operating without excessive noise or vibration?

8. Is the discharge point intact, unobstructed, and positioned to prevent re-entry of contaminants?

9. Are control panels, alarms, and interlocks operational?

1. Was a smoke test carried out to verify effective capture?

2. Is the face/capture velocity at the hood within design specifications?

3. Is the transport velocity in ducts within the required range for the contaminant type?

4. Is the static pressure reading within the expected range?

5. Is the airflow volume (m³/s) within design parameters?

6. Is the differential pressure across filters within the safe operating range?

7. Are the airflow indicators calibrated and reading accurately?

8. Is the fan motor current drawn within the normal operating range?

1. Are LEV inspection/test records available and up to date (≥5 years retention)?

2. Are maintenance logs complete and current?

3. Have all scheduled filter changes, duct cleanings, or fan services been carried out?

4. Are any recent repairs or modifications documented?

5. Are operators trained and using the LEV correctly (keeping the source within the hood/capture zone)?

6. Is the system free from clutter or obstructions in the capture area?
