Be Alert To Frostbite Conditions
Exposed skin can freeze within one minute at wind-chill equivalent temperatures below -25 F. Frostbite affects the extremities, such as fingers and toes. If a body part has been frostbitten once, it is more susceptible to frostbite again, even in milder conditions. Redness and a burning sensation are indications frostbite will occur unless the extremity is warmed. Numbness is an indication that frostbite has already taken place. If frostbite is discovered, hold the affected part tightly against the warm skin or another part of the body; (for example place frozen fingers under arm). When thoroughly warmed, keep covered and make an effort to keep area from freezing again.
Hypothermia
Under conditions of prolonged exposure to cold, the body may begin to lose heat faster than it can produce it. A condition called hypothermia begins to develop. The symptoms become very apparent, and include:
- uncontrollable shivering
- vague, slow, slurred speech
- memory lapses
- incoherence
- immobile, fumbling hands
- frequent stumbling
- lurching gait
- drowsiness
- apparent exhaustion
