It’s important to ensure that the dust generated during fettling is properly controlled, particularly when there is a risk of exposure to silica. In most cases, the most practical and effective way of doing this is to install well designed local exhaust ventilation. The Health and Safety Executive have developed a number of sheets providing practical advice on how to control dust and fume generated during foundry processes, including fettling. For small castings they recommend the installation of an extracted booth. The work is carried out inside the booth which then contains the dust generated allowing it to be removed effectively by the extraction.
Local Exhaust Ventilation (LEV) is a machine that extracts air from a process as a way of controlling and reducing the exposure of workers to dust, fumes and vapor which could be hazardous to their health. It is a legal requirement, as set out in the Health and Safety at Work Act 1974, for any employer to maintain working conditions for employees. Any employer that uses LEV techniques in the workplace must have equipment examined and tested at least “every 14 months” to ensure it is working effectively and safely.
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.
Equipment that draws pollutants from an operation or process in the working environment. Made up of an inlet like a hood, slit, arm, cabinet or booth. This will be located near to or close to the area of the substance release. All suchlike equipment needs to be connected by ducting and a fan to enable the movement of air. The removed air passed through a filter or is extracted to atmosphere away from the workplace. How Welding Supplies Direct can help ? WE will carry out a thorough tests in line with COSHH Regulation 9 as detailed in HSE Guide HSG258 Our levels of service can be tailored to your Companies needs. However, most clients choose to take advantage of by combining servicing with the LEV testing. Read more info at HSE LEV Testing.
The employer decides who to employ or consult and needs to be an ‘intelligent customer’ to get the best result. HSE has produced simple guidance to help the employer choose a supplier when they are considering installing LEV (see HSE leaflet Clearing the air). Suppliers need to prepare their information to respond to this approach.
