CONDITIONS

Vibration and Cold

It is believed that a condition called Raynaud’s Phenomenon, which
affects the fingers of certain individuals, may be brought about by
exposure to vibration and cold. Exposure to vibration and cold may
cause tingling and burning sensations, followed by loss of color and
numbness in the fingers. The following precautions are strongly
recommended, because the minimum exposure which might trigger the
ailment is unknown.

• Keep your body warm, especially the head, neck, feet, ankles,

hands, and wrists.

• Maintain good blood circulation by performing vigorous arm

exercises during frequent work breaks, and also by not smoking.

• Limit the hours of operation. Try to fill each day with jobs where

operating the trimmer or other hand-held power equipment is not
required.

• If you experience discomfort, redness and swelling of the fingers

followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.
