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 colour 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, and also by not smoking.
• Limit the number of 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 exposing
yourself further to cold and vibration.
REPETITIVE STRESS INJURIES
It is believed that overusing 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.
