Vibration of Power Hand Tool and Discomfort Experience among Malaysian Industrial Workers

Abstract:

In reality, people who worked with power vibrating tools exposed with the vibrated syndrome that effect their normal life especially who involved for long time period. Hand-arm vibration (HAV) is a widespread hazard in many industries and occupations involving the use of handheld power tools or hand-fed machines. This paper describes a research and observation on the vibrating hand tool. The objective of this study is to measure and compare the grip strength and hand arm vibration before and after using the Ready-Reckoned standard for industrial workers. Continually, an analysis is conducted due to the pain and discomfort experience that face by the workers. This research also do the analysis about the effects of the vibration to the workers hand depend on the duration of handling the power hand tool. Hundred respondent was involved which 50 men and 50 women who had been identified as an industrial worker and working with power hand tools or machinery. The respondents were interviewed and answer Q-Survey that directly conducted at their workplace after doing the test. As the result, worker who works 8 hours per day, the exposure limit value (ELV) is 5m/s, it can cause fatal effects. Most of workers suffered with fingers that gone white on cold exposure and weakness in hand grip.
