Local Exhaust Ventilation (LEV) Testing

Local Exhaust Ventilation (LEV) is a control measure that aims to control exposure to hazardous substances by preventing their release into the workplace atmosphere.  The COSHH Regulations 2002 (as amended) oblige companies by law to have their LEV systems thoroughly checked. Regulation 9 (2) states that a thorough examination and test of all systems needs to be carried out at least every 14 months. Some systems that handle more hazardous substances such as those that can cause cancer or asthma (as per Regulation 6 or Schedule 4) may need to be tested more often as the risk of ill health is higher when the LEV fails.

The thorough testing measures a range of parameters and the condition of the full system is visually inspected along with how it is used by workers. The LEV survey checks that it is working correctly, effectively and doing the job it should.  The report highlights defects and any areas for improvement to the site and gives a list of checks and required maintenance that the site can do themselves in the interim.  The HSE guidance book HSG258 and HSE guidance leaflet INDG408, outline more detail on this subject, how to buy and use LEV, and how the test should be undertaken.  Our LEV testing is carried out by qualified technicians with a broad range of experience of all types of LEV systems.
