The health effect of noise at work and techniques for noise reduction in industrial power tools case study (CIRCULAR CUTTING SAWS )

Small industrial power tools such as saws, drills, sanders, and nailing guns emit noise levels that can be hazardous to the operator and others in the surrounding area. High noise levels generated form these tools are linked to health risks and significant amounts of noise induced hearing loss in the work force.Circular saws are used in many different industries, in countless ways. Such saws are invariably a hazard to hearing of workers in the vicinity of the machines, and generate noise of a particularly objectionable quality. Operators of circular saws have an obligation, under law, to take all practicable steps to reduce the noise emissions of these machines by engineering means. Management must also ensure that workers not immediately involved in the operation of the saws are isolated from the noise. Good reductions in noise levels are achievable. On certain saws the noise levels can be reduced to below 85dB (A), so that the hearing of operators can be protected. On other operations it will be impracticable to achieve such reductions, and hearing protectors will also have to be worn.
