Abstract

Vibration among hand held power tools are commonly blamed for the causation of upper limb musculoskeletal disorders among industrial workers. Hand arm vibration is a serious problem in the workplace. Workers are mostly exposed to hand arm vibration through the usage of power tools. The study is about the objective and subjective measurements hand arm vibration levels during power tool usage. Objective measurements of vibration have been set forth by certain standards; however the implementation of the vibration measurement becomes a challenge with the addition of vibration attenuation gloves. Therefore the effectiveness of vibration attenuation gloves must be measured. In this study, the effectiveness of vibration attenuation gloves and vibration values for two types of power tools were measured, Bosch and Makita hand grinders. Results indicated that the both Bosch and Makita grinders do not have a difference in terms of vibration values. The anti vibration gloves were found to be cumbersome to use, a burden while operating power tools, but the gloves were easy to use by the participants.
