Qualified LEV Engineers

Our LEV engineers have undertaken extensive training to ensure that your team are properly protected from substances hazardous to health. Some of the BOHS LEV Proficiency Qualifications include: BOHS P600 - Methods for Testing Performance of LEV, P601 - Thorough Examination and Testing of LEV Systems, P602 - Basic Design Principles of LEV Systems, and P604 - Performance Evaluation, Commissioning, and Management of LEV. All of our team have also achieved W201/ M200 - Basic Principles in Occupational Hygiene.

We hope that this level of expertise gives customers confidence in our service levels and the solutions we specify. All systems are specified inline with HSG258 (HSE's guide to local exhaust ventilation - LEV) and all solutions meet regulatory requirements (such as COSHH).

LEV Commissioning

Commissioning an LEV System

Once a solution has been specified, RVT Group offer two types of delivery service: delivery with full installation, or delivery only (customer install).

When we provide delivery with full installation, we commission the system and provide a full written report in-line with HSE legislation. This involves a detailed report including the design of the system, information about the hazards it’s intended to control, equipment specifications, training given to staff, PPE controls, and results of the qualitative and quantitative tests.

Quantitative results are based upon meeting certain minimum duct velocities and capture velocities which allow us to ensure the system is capable of capturing and moving the airborne hazard through the ductwork fast enough to ensure there is no drop-out in the duct. Qualitative results are based upon visually demonstrating that the system is operating correctly by using a smoke test and tindel beam to witness the hazard being captured.

If you opt for a delivery only service, we will provide a TExT certificate to confirm that the unit is in full working order, but the customer must check that it is operating correctly once installed on site.
