This article focuses on pneumatic tools that are among the most damaging sources of noise pollution. The National Institute for Occupational Safety and Health estimates that more than 30 million workers in the United States are exposed to hazardous noise, costing the economy about $1 billion every year. There is no magic solution to all noise control problems, and this remains true even when we are dealing just with pneumatic tools. Each case must be considered separately, and the solution to be used must satisfy the often conflicting demands of at least five criteria simultaneously. The sound power level produced by a pneumatic tool is a product of many interrelated parameters: operating pressure, pressure drop, expansion volume, exhaust air velocity, speed of device, exhaust air, airflow, length of exhaust path, and tool power. Good standards are available for evaluating the noise of many components, and suppliers provide data on their products that can be used for comparison.

Abstract CYCLOPS S1 (formerly Alco M) was originally developed for chisel and pneumatic tool purposes. It is now used for many other cold and hot work applications because of its outstanding toughness and resistance to fatigue. It gives excellent results in those instances where shock and impact are major factors. It may be carburized for those applications where high wear resistance and great core strength are required. Its many applications include shear blades, rivet busters and forging dies. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-352. Producer or source: Cyclops Corporation.
