Extended Operation/Extreme Conditions

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 recom-
mended, 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 unit 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.

Hot Humid Weather

Heavy protective clothing can increase operator fatigue which may lead to heat stroke. Schedule heavy work for early
morning or late afternoon hours when temperatures are cooler.
