may contribute to a condition called Raynaud’s

Syndrome in certain individuals. Symptoms may include

tingling, numbness and blanching of the fingers, usually

apparentuponexposuretocold.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 unknown at

present 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 yourbodywarmin cold weather. When
