Abstract

Hand-arm vibration is a transmission of vibration from the use vibratory machinery or tools to a worker’s hands and arms. This paper looks at the attenuation characteristics of the frequency weighing curve Wh and presents some comparative results of vibration impacts from the use of several hand tools. Comparisons were made between the measurement methods prescribed by ISO standards and the data analysis of the raw vibration data. The results show that the measured impact as per the applicable ISO standards is significantly lower than the calculated vibration impact from the raw vibration data. This paper investigates other potential parameters that may be used to characterize the cumulative impacts from the hand-arm vibration. These additional analytical parameters may be used in evaluating the cumulative hand-arm vibration impacts in a more comprehensive way.
