Fettling normally involves the use of powered hand tools such as chippers and grinders. The operation presents a number of significant risks. Using power tools exposes the workers to high noise levels and hand-arm vibration. There is also a risk from exposure to the dust generated by the process. The dust will largely consist of metal particles, but this is usually of low toxicity. The main concern occurs where sand is used for the moulds in which the metal is cast. This is crystalline silica. Some particles of sand from the mould adhere to the metal and grinding during fettling can lead to the release of fine dust including particles of respirable crystalline silica. “Respirable” particles are smaller than 10 microns in diameter and can reach the deepest regions of the lung. Regular, repeated exposure to respirable crystalline silica can lead to silicosis, a serious, debilitating lung disease.
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.
As LEV is a control measure under COSHH Regulations it must be regularly and thoroughly inspected and tested. As stated above, LEV regulations outline that any employer who uses local exhaust ventilation to control hazardous substances must ensure that it is operating effectively. Local Exhaust Ventilation Testing is a legal requirement in the UK. All equipment must be thoroughly examined and tested by a competent person at least every 14 months to ensure employees are safe.

The requirement for competence for suppliers of goods and services means that the extent and depth of their knowledge and capability must be sufficient to assess and solve the problems they are likely to meet. The more complex a control scenario is and the more serious the results of failure, the greater the degree of competence required. Many trades recognise levels of competence based on qualifications and tests of capability, as well as experience of successful problem-solving over a number of years.
