Extended Operation/Extreme Conditions

Il is believed that acondition called Raynaud's Phenomenon, which affects the fingers

certain individuals, may be

brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning sensa-

tions, followed by loss

color and numbness in the fingers. The following precautions are strongly recommended,

because the minimum exposure, which might trigger the aiiment, is unknown.

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

and wrists.

•Maintain good blood circulation by performing vigorous arm exer-

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

•Limit the hours

operation. Try to fill each day with jobs where op-

erating the unit or other hand-held power equipment is not required.

Ifyou

experience discomfort, redness, and swelling

ofthe

fingers fol-

lowed by whitening and loss

feeling, consult your physician before

further exposing yourselfto cold and vibration.

Repetitive Stress Injuries

is believed that overusing the muscles and tendons

the fingers, bands, arms, and shoulders may cause soreness,

swel1ing, numbness, weakness, and extreme pain in tbose areas. Certain repetitive band activities may put you at ahigb

risk for developing aRepetitive Stress Injury (RS!). An extrerne RSI condition

Carpal Tunnel Syndrome (CTS), wbicb

could occur when your wrist swells and squeezes avital nerve that runs through the area. Sorne believe that prolonged

exposure to vibration may contribute to CTS. CTS can cause severe pain for months or even years.

reduce the risk

RSIfCTS, do the following:

•Avoid using your wrist in abent, extended, or twisted position.
