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.
What does LEV testing involve? A thorough examination of equipment including hoods, filters and ducts, measurement of the technical performance using the appropriate equipment and assessment of the effectiveness of the LEV system. We will make recommendations should your system not be up to the required standard. All work is carried out according to HSE guidance which governs LEV testing.
A comprehensive LEV report will also be produced for each piece of LEV equipment tested. All of our LEV reports include photos and/or schematic diagrams showing all test point locations, which are also clearly identified on the ducting as required by the HSE. This includes the following in line with guidance from HSG258: Following an inspection, our professional LEV consultant will mark the LEV system as a pass or fail. We will also assist you in improving all control measures where necessary.
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 on Local Exhaust Ventilation LEV Testing.
Where employers use or intend to use LEV they must ensure that it is appropriate for the task, installed and operated correctly and subsequently maintained so it continues to operate as when originally installed. Suppliers of LEV can play an important role in helping the employer with the design, installation and maintenance of the equipment. This guidance is therefore intended to help employers and suppliers as well as managers, trade union and employee safety representatives to work together to provide effective LEV so that workers are not breathing in hazardous substances. Different chapters will be more appropriate for different audiences.
