HSE defines an LEV Examination as a thorough and systematic examination of your system. This makes sure that it can perform as intended and will contribute to the adequate control of exposure.
We follow a detailed procedure when performing an LEV Examination and we will:
- Check your filters to see what condition they are in.
- Measure the rotational speed of the motor with a tachometer.
- Take velocity pressure and static pressure of all test points on the system and face velocities at open hoods.
- Record the pressure drops across the filters.
- Measure ambient dust level.
- Measure contaminant in the returned air to the workshop.
- Measure the decibel readings between 2-3 meters of each machine.
- Measure the dust level reading in the breathing zone of employees.
- Carry out a smoke test.
- Complete a face velocity test.
- Provide you with an LEV report that complies with the legal requirements from both COSHH and HSE.
Following your LEV Examination, we can assist in the design, alteration and improvement of all systems if needed. Any required or possible improvements will be listed in order of priority, under: Report Findings & Prioritised Action Plan.
