What is LEV?
Every year, thousands of workers in Britain develop occupational diseases from breathing in certain dusts, fumes or other airborne contaminants at work. LEV is an extract ventilation system that takes dusts, mists, gases, vapour or fumes out of the air so that they can’t be breathed in. Properly designed LEV will:
What are typical LEV Applications?
In conjunction with BOFA we can test all makes of LEV equipment, these include: Hand soldering (tip and volume extraction), Fume cabinets, Re-flow ovens, Wave solder Ovens, Laser engraving and marking, Printing, Dust extraction, Milling, Routing, Nail polish application (beauty salons).
What are my Responsibilities?
Regulation 9 of the Control of Substances Hazardous to Health regulations (COSHH), as detailed in HSE Guide HSG258, requires that any measures taken to provide effective control through the use of Local Exhaust Ventilation (dust or fume extraction equipment) must be maintained in effective working order and also in good repair. Furthermore the employer must ensure that LEV equipment has been suitably installed and 'must be thoroughly appraised and tested at least once every 14 months. (COSHH, Regulation 9.2)
How do I comply?
In order to be compliant a thorough examination should be carried out as part of the installation process and at least once every 14 months thereafter. It is also the duty of the employer to keep a suitable record of the examination for a period of at least 5 years. This record should also include details of repairs carried out as a result of the examination and test. Solder connection recommends scheduling in your LEV Test every 12 months.
What does LEV testing involve?
The thorough examination and test checks the control effectiveness of your LEV systems. The test includes air flow and pressure measurements which are then compared to the commissioning report, issued when the equipment was installed. The control effectiveness will be demonstrated to the user by means of a smoke test or Tyndall lamp. A test label will be attached to each machine indicating the date of the test and the next test due date. A “Failed” label will be attached to any equipment which fails to meet the regulations, and use of the equipment should be ceased until a repair has been facilitated.
