Cold Stress

When exposed to cold temperatures, your body begins to lose heat faster
than it can be produced. Prolonged exposure to cold will eventually use up
your body's stored energy. The result is hypothermia or abnormally low
body temperature. A body temperature that is too low affects the brain,
making the victim unable to think clearly or move well. This makes
hypothermia particularly dangerous because a person may not know it is
happening and will not be able to do anything about it.

Loss of consciousness, death!
First Aid:
• Alert your supervisor, and request immediate medical
assistance (911 or Security-5911).
• Move the victim into a warm room or shelter.
• Remove wet clothing.
• Warm the center of their body first: chest, neck, head, and
groin.
• Warm beverages may help increase the body temperature,
but do not give alcoholic beverages.
• After their body temperature has increased, keep the victim
dry and wrapped in a warm blanket, including the head and
neck.
Frostbite:
Frostbite is an injury to the body that is caused by freezing. Frostbite causes a
loss of feeling and color in the affected areas. It most often affects the nose, ears,
cheeks, chin, fingers, or toes. Frostbite can permanently damage body tissues and
severe cases can lead to amputation. Be aware of the early symptoms, and get to
a warm area.

When working outside in winter conditions:
Wear appropriate clothing consisting of
several loose fitting layers.
Make sure to protect the ears, face, hands, and
feet in extremely cold weather.
Boots should be waterproof and insulated.
Wear a hat; it will keep your whole body
warmer. (Hats reduce the amount of body heat
that escapes from your head.)
Move into warm locations during work breaks;
limit the amount of time outside on extremely
cold days.
Monitor your physical condition and that of
yourself and coworkers.
The Numbers:
2 X the number of Americans that die from winter
cold (63%) vs summer heat (31%)
25 X Faster the speed that wet feet loose heat vs
dry feet
700 deaths each year from hypothermia
