■ It has been reported that vibrations from hand-held tools
■■
may contribute to a condition called Raynaud’s Syndrome in certain individuals. 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 operat-
ing the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major
factor contributing to Raynaud’s Syndrome.
b) After each period of operation, exercise to increase
blood circulation.
c) Take frequent work breaks. Limit the amount of
exposure per day.
d) Keep the tool well maintained, fasteners tightened
and worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician
about these symptoms.
