Ergonomic evaluation of the wood cutting task using chain saw.

Workers whose hands are regularly exposed to hand-arm vibration may suffer from damage to the tissues of the hands and arms, which cause the symptoms collectively known as hand-arm vibration syndrome. However, investigations have shown that vibration hazards can be controlled and risks might be reduced by good design of the task/tools. In the present study, an experiment was conducted for the evaluation of risk in operating chain saw.
