Symptoms may include tingling, numbness, and blanching of the fingers, usually apparent upon exposure to cold. Hereditary factors, exposure to cold and dampness, diet, smoking, and work practices are all thought to contribute to the development of these symptoms. It is presently unknown what, if any, vibrations or extent of exposure may contribute to the condition. There are measures that can be taken by the operator to possibly reduce the effects of vibration:

a)Keep your body warm in cold weather. When oper- ating the unit wear gloves to keep hands and wrists warm. It is reported that cold weather is a major factor contributing to Raynaud’s Syndrome.
