STUDY ON VIBRATION REDUCTION IN HAND OPERATED POWER TOOLS

This review paper is described Every day workers are exposed to health and safety risks, due to work environment and the machineries they use. Some of these risks, vibrations for example, are usually underestimated by workers as well, because vibrations do not represent an immediate risk for the health. The vibrations can cause some professional diseases whose symptoms can appear after many years too. This is not a good reason to ignore the problem; in fact the consequences of a long exposure time can be very serious. A deeper knowledge of diseases caused by vibrations, laws, the best precautions and safety systems can represent a start to limit the phenomenon.The research about hand operated machineries can represent a stimulus to use ergonomic instruments in order to guarantee the health and the safety of the workers.
