OPERATOR SAFETY

VIBRATION AND COLD

• ItisbelievedthataconditioncalledRaynaud’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 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. 

• Keepyourbodywarm,especiallytheheadand

neck, feet and ankles and hands and wrists. 

• Maintaingoodbloodcirculationbyperforming

vigorous arm exercises during frequent work 

breaks and also by not smoking. 

• Limitthenumberofhoursofoperation. 

Try to fill each day with jobs where operating the 

chain saw, or other hand-held power equipment 

is not required. 

• Ifyouexperiencediscomfortrednessand 

swelling of the fingers, followed by whitening 

and loss of feeling, consult your physician before 

further exposing yourself to cold and vibration.

REPETITIVE STRESS INJURY

• Itisbelievedthatover-usingthemusclesand

tendons of the finger, hands, arms and  

shoulders may cause soreness, swelling,  

numbness, weakness and extreme pain to the 

areas just mentioned.  

Certain repetitive hand activities may put you 

at a high risk for developing a repetitive stress 

injury (RSI). 

• AnextremeRSIconditionisCarpalTunnel

Syndrome (CTS) which could occur when your 

wrist swells and squeezes a vital nerve that runs 

through the area. Some believe that prolonged 

exposure to vibration may contribute to CTS.  

CTS can cause severe pain for months or even 

years. 

To reduce the risk of RSI/CTS, do the following:

• Avoidusingyourwristinabent,extendedor

twisted position. 

• Takeperiodicbreakstominimizerepetitionand

rest your hands.

The sooner RSI/CTS is diagnosed, the more 

likely permanent nerve and muscle damage can 

be prevented.
