As mentioned in HSE’s HSG258: Controlling Airborne Contaminants at Work: A Guide to Local Exhaust Ventilation (LEV), an LEV test – otherwise known as a COSHH test – is a “detailed and systematic (annual) examination” that must be carried out in order to make sure that the LEV system or equipment performs as intended by design. The examination will indicate whether “adequate control is being achieved”, and if any mechanical issues are identified, steps must be taken in order to enhance performance.
Dust extraction and fume extraction are legal requirements that all business owners must abide by in order to ensure that health and safety standards are met. Inadequate testing could result in prosecution, invalidated insurance, and it could also impact the wellbeing of workers. Serious, long-term, and potentially fatal, health conditions could develop if LEV testing isn’t completed – which is any business owner’s worst nightmare, both from an ethical and financial standpoint.
An LEV test must be performed by a competent, qualified person in order so that the results collected are as accurate and reliable as possible.
During an LEV test, an extraction unit’s air flow will be measured against initial performance levels in order to determine whether it’s still working as it should. The test can be split into three distinct phases:
The local exhaust ventilation system’s condition will be examined, which includes:
An LEV report will highlight:
Evaluating an LEV’s technical performance will include:
Once the LEV test has been completed, the examiner will highlight any wear and tear, along with any part replacements that are needed. The report will then be signed by the examiner.
