Servicing and Maintenance

At Laboratory Specialist Services, we offer a complete and professional inspection/maintenance service. As part of the HSE and COSHH guidelines it is a legal requirement that any LEV (Local Extract Ventilation) system that removes fumes must meet all current Health and Safety regulations.

LEV inspection and preventative maintenance plays a vital role in protecting your staff/operators and also in extending the working life of your LEV plant. As a minimum, all LEV systems must be examined and tested at least every 14 months.

In addition to a full mechanical inspection check list and complete set of airflow face velocity readings, your current annual inspection report should also include the following:

  • Full inspection of the associated extract system
  • Electrical full load current readings on the fan/motor
  • Extract fan inlet and outlet static pressure measurements
  • Tachometer fan/motor speed readings


These checks are just some of the points which must be covered under current COSHH (Control of Substances Hazardous to Health) Health and Safety Standards. Local Exhaust Ventilation systems must be tested to HSG258 ('Controlling airborne contaminants at work'), EN 14175 (the EN standard for installation and testing of Fume Cupboards) and BS 7258 ('Specification for safety and performance').

We would be pleased to provide a fully detailed proposal for your annual inspection/maintenance service.
