WARNING: 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 ngers,
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:
nKeep your body warm, especially the head, neck, feet, ankles, hands and
wrists.
nMaintain good blood circulation by performing vigorous arm exercises during
frequent work breaks and also by not smoking.
nLimit the hours of operation. Try to ll each day with jobs where operating the
brush cutter or other hand-held power equipment is not required.
nWear gloves. Gloves help reduce the transmission of machine vibration to your
hands.
IMPORTANT: If you experience discomfort, redness and swelling of the ngers
followed by whitening and loss of feeling, consult your physician before
further exposing yourself to vibration and cold.
