HOT HUMID WEATHER
Heavy protective clothing can increase operator fatique
which may lead to heat stroke. Delay heavy work until the
temperature drops.
VIBRATION AND COLD
It is believed that a condition called Raynaud's Phenom-
enon, which affects the fingers of certain individuals may
be brought about by exposure to vibration and cold. Expo-
sure 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.
REPETITIVE STRESS INJURIES
• It is believed that overusing the muscles and tendons of
the fingers, hands, arms and shoulders may cause sore-
ness, swelling, numbness, weakness and extreme pain to
the areas just mentioned.
Certain repetitive hand activities may put you at a high risk
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 posi-
tion.
• Keep your body warm, especially 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 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.
• 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.
EYE AND HEARING PROTECTION
• Wear eye protection goggles.
• Wear hearing protection. If this guideline is not followed,
hearing loss can occur.
WEAR PROPER CLOTHING
• Snug fitting, durable clothing should be worn. Trousers
should have long legs. DO NOT WEAR SHORTS.
• Do not wear loose fitting clothing, scarfs, neckties, jewelry
or any item that may be drawn or tangled in the fan.
• Wear shoes with non-skid soles. DO NOT wear open-toed
shoes or operate unit bare footed.
• Wear no-slip, heavy work gloves to improve your grip on
the handles. The gloves also help reduce the transmission
of machine vibration to your hands.
