Work must go on regardless of cold weather, which can lead to frostbite and hypothermia. The following advice was compiled from information from the CDC, the Mayo Clinic and the National Library of Medicine.

What
Frostbite causes a loss of feeling, a prickly feeling, red, pale or waxy skin. Most susceptible are the fingers, toes, ears, nose and chin. Severe cases may cause blistering and pain, and require amputation.

A body temperature of less than 95 F signals hypothermia. Other signs include shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness. Severe cases may lead to unconsciousness and death.

When
Frostbite occurs when the skin is exposed to freezing temperatures for extended periods of time. You are more likely to develop frostbite if you smoke, have diabetes, have poor supply of blood to the legs, take beta-blockers.

Hypothermia can occur even at 40 F and higher if a person becomes chilled from rain, sweat, or submersion in cold water.

What to Do
For suspected frostbite, check for hypothermia, protect skin from further exposure, remove wet clothes once inside, rewarm frostbitten areas with warm, not hot, water, not direct heat (which can cause burns), don't walk on frostbitten feet or toes, seek medical attention.

For suspected hypothermia, remove wet clothes, warm the center of the body first"?uchest, neck, head, and groin - with blankets, clothing towels sheets, etc., give warm liquids but not alcohol, seek medical attention. In some cases, hypothermia victims who appear to be dead can be successfully resuscitated so CPR should be provided while the victim is being warmed, until the victim responds or medical aid becomes available.
