LEV monitoring tips

Recently, one of our consultants was carrying out a survey in a foundry. They had installed this type of booth for their fettling operations. However, as can be seen in the following photograph, The booth was not being used in the way intended – the worker was carrying out the work outside the booth. The dust generated was not contained and, consequently, the extraction would not be as effective as it should be. The worker will have a higher exposure than if he carried out the fettling inside the booth.

CoSHH regulations require most LEV systems to be thoroughly tested at least once every 14 months. This applies to all oil mist, welding fume, smoke and dust extraction units that you currently have on site. This examination must be undertaken by a competent person and the tests and reports must conform to HSE standards. HSG258 provides the recommended procedures to achieve these statutory requirements.

LEV Testing is a legal requirement in the UK for compliance with health and safety standards. LEV Test reports often form part of a company’s insurance policy. Inadequate testing can result in employers being prosecuted, insurance policies being invalidated and even employees becoming ill.

Dutyholders should provide information about the full extent of an airborne dust cloud, as this is rarely visible. In some cases, such as when all the particles are smaller than ‘inhalable’, it will be completely invisible. Tyndall illumination uses the forward scattering of light to show up the cloud. Alternatively, if smoke is released into the cloud this will show up its shape, size, speed and direction.
