Abstract
The transfer of acceleration and energy from vibrating tools to operator's hands was investigated. Average values of amplitude and phase of tool energy were measured in a range of 6.3 to 1000 Hertz (Hz) for 75 workers, and acceleration was measured for chipping hammers and grinders. The tool energy was below 80Hz. Acceleration of chipping hammers exceeded exposure limits proposed by the International Organization for Standardization while grinders were within those limits. The authors conclude that larger handles give lower values of displacement mobility. They suggest that the actual energy transmitted from chipping hammer chisels to the hand be measured and further investigations of chisel acceleration be performed.
