FROSTBITE
The most common injury caused by
exposure to cold temperatures is frostbite.
Body parts most susceptible to frostbite include the nose, ears, chin,
fingers and toes. Frostbite occurs when
the blood flow through a body part is restricted due to extreme cold
temperatures and ice crystals then begin to form in the body tissue.
Symptoms: The first symptom of frostbite is a slightly flushed skin
color. The color of the skin then
changes to white or grayish yellow and finally grayish blue. Pain may be felt during the early stages,
however, the pain may cease in later stages.
The frostbitten area will also feel very cold, numb and the outer layer
of skin may feel "hard".
First Aid Treatment: Move the victim to a warm location. Place the frostbitten part into a warm water
bath between 100-105 degrees. Do not use
hot water. Handle the part with extreme
care. Do not rub or massage the
area. Avoid exposing the part to hot air
or metal objects. The re-warming process
may take between 30-60 minutes. Severe
frostbite should be handled by medical personnel.
HYPOTHERMIA
Prolonged exposure to cold temperature
may also cause the cooling of the body's inner core, more commonly known as
hypothermia. This loss of body
temperature can be fatal.
Symptoms: Hypothermia symptoms include shivering, dizziness, numbness,
confusion, weakness, impaired judgment, impaired vision and drowsiness. Later stages of hypothermia include the loss
of consciousness, decreased pulse and breathing rate, coma and possible
death.
First Aid Treatment: Professional medical treatment should be
obtained. Move the victim to a warm
area. If available, have the victim
change into a set of dry, warm clothing.
If the victim is fully conscious, a warm drink may be given. Do not give the victim a caffeinated or
alcohol beverage.
PROTECTIVE MEASURES
a. Avoid
consumption of caffeinated or alcohol beverages. Temporary warmth may be achieved; however,
body heat loss will occur.
b. Wear
a hat and scarf. Up to 50% of heat loss
occurs from the head and neck.
c. Wear
three (3) layers of clothing.
1.
Against the skin: a warm, breathable
synthetic fabric such as Gore-Tex or Thinsulate will allow moisture to escape
to the next layer.
2. Middle: layer of wool clothing to draw
moisture away from skin.
3. Outer: water-resistant or repellant material.
d. Frostbite
and hypothermia may occur when temperatures are above freezing due to extended
periods of exposure and windy conditions.
