Hand-Arm Vibration Exposure in Rock Drill Workers

From The Chartered Society for Worker Health Protection, this study is a comparison between measurements with hand-attached and tool-attached accelerometers.

This study is important because it shows that the choice of accelerometer placement affects the measurement result. The working technique, specifically the individual handgrips used by workers, is an important factor to consider when planning measurements of hand-arm vibrations in the workplace. This study also reveals a potential for exposure reduction among rock drillers by altering how the workers grip a tool handle during drilling.

In the study the SV 106D six-channel vibration meter was used, along with a SV 105 which is the hand-arm adapter with triaxial accelerometer.
