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, 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 and neck, feet and ankles,
and hands and wrists.
• Maintain good blood circulation by performing vigorous arm exercises
during frequent work breaks.
• Limit the number of hours of operation. Try to fill each day with jobs where
operating the chain saw 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 exposing
yourself further to cold and vibration.
Failure to observe these instructions could result in damage to your health.
Repetitive stress injuries
It is believed that over-using the muscles and tendons of the fingers,
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).
To reduce the risk of RSI, do the following:
• Avoid using your wrist in a bent, extended or twisted position.
• Take periodic breaks to minimize repetition and rest your hands. Reduce
the speed and force in which you do the repetitive movement.
• Do exercises to strengthen hand and arm muscles.
• See a doctor if you feel tingling, numbness or pain in your fingers, hands,
wrists or arms. The sooner RSI is diagnosed, the more likely permanent
nerve and muscle damage can be prevented.
Failure to observe these instructions could result in damage to your health.
