UK provider offering LEV testing and monitoring
Due to concerns over exposure to lead, the soldering industry has moved toward the use of lead free solders; these tend to be a tin/copper alloy. In order to compensate for the removal of lead another flux substance has to be used to aid the flow of the solder. One of the most commonly used fluxes is rosin or colophony. When heated, rosin creates fumes (known as Rosin Based Solder Flux Fume – RBSFF). This fume is composed of two fractions, the particulate fraction contains rosin sublimates and thermal decomposition products, which are predominantly a mixture of diterpentine acids, this fraction makes up approximately 90 % of the total fume. The remaining gaseous phase of the fume is composed of low molecular weight organic compounds including acetone, methyl alcohol, aliphatic aldehydes and other hydrocarbons.
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.
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.
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 extra details at Local Exhaust Ventilation LEV Testing.
This guidance explains how local exhaust ventilation (LEV) can help employers effectively control exposure to gas, vapour, dust, fume and mist in workplace air by extracting the clouds of contaminant before people breathe them in. It describes the principles of design, installation, commissioning, testing and examination of proportionate ‘ventilation controls’.
