LEV

An effective LEV system should be well designed and constructed, properly used and maintained in good condition

This along with regular LEV inspections and servicing will ensure that the system is safe for the pollutants being controlled and is in compliance with HSE regulations.

Systems are classed as Local Exhaust Ventilation (LEV) if they are used to control, capture or contain airborne contaminants such as dust or fumes. These may be controlled “at” or close to the point of emission and then conveyed through the system to a point where they can be safely collected in filters or released to atmosphere.

The following are just some examples of the many kinds of LEV systems:

  • Fume cupboards
  • Welding hoods
  • Paint spray booths
  • Wood work extraction
  • Dust booths
  • Vehicle exhaust extracts
  • Canopies
  • Hoods

We work to guidance published in HSG258 “Controlling airborne contaminants at work” which is an up to date HSE guide to local exhaust ventilation. This publication states that tests must be carried out at least once every 14 months on Local Exhaust Ventilation Systems or even more regularly for some substances and processes.

Our engineers are trained to British Occupational Hygiene Society (BOHS) P601 standard which covers:

  • Initial appraisal and test of LEV systems
  • Thorough examination and test of LEV systems

The Local Exhaust Ventilation test is designed to determine the efficiency and suitability of an extraction system. It requires the use of airflow/pressure instruments and visual aids such as smoke testing/dust lamp checks to gain results.

Our engineers will then study these results and use their experience to decide if the system is deemed effective. They would also identify any possible problems with the system such as design flaws, defects and maintenance issues that might affect the performance of an LEV system now or in the future.

Upon completion of onsite LEV testing, a thorough report will be issued to you that contains the findings of our tests. This report will also detail any actions that may be required to ensure that your system meets the required standard. Any equipment tested by us will also be labelled to indicate that a test has been carried out and also to assist in equipment identification.

Once registered on our database a reminder will then be issued one month before the next examination is due in order for you/us to plan your next visit if required.
