Vibrations transmitted by hand-held electric tools used in mining and mine remediation activities
The occupational exposure to hand-arm vibrations (HAV) transmitted by hand-held power tools should be assessed on the basis of the acceleration values measured at the tool handles; specifically when the otherwise available information on the probable magnitude of the vibration (i.e. information provided by the manufacturer or included in the vibration data banks) is not consistent with the operating conditions at the workplace. The article discusses the results of a study focused on hand-held electric tools,with particular reference to rotary and percussion hammers and angle grinders,and includes a comparative analysis of the acceleration signals simultaneously registered on the two handles of the tool. The investigation demonstrated that the determination of the vibration total value on both handles is needed not only for the exposure evaluation,but also for the tool emission characterization,as required by the new test codes.
