Listen to the radio to television for weather reports and emergency information.

Dress for the season.
Wear several layers of loose-fitting, light--weight clothing rather than one layer of heavy clothing.  The out garments should be tightly woven and water repellent. Mittens are warmer than gloves. Wear a hat or other head covering.  Most of the body's heat is lost through the top of the head. Cover your mouth with a clean scarf to protect your lungs from the cold air.

Be careful when shoveling snow. 
Overexertion can bring on a heart attack - a major cause of death in the winter. If you must shovel snow, do some stretch exercises before going out and don't overexert yourself.  Consider purchasing a snow blower (similar to a lawn mower for snow), which requires far less exertion to remove a significant volume of snow than a shovel.

Check on neighbors who may have trouble staying safe during winter storms.
Elderly or homebound residents are at particular risk.  Make sure they have adequate hearing and food and offer to clear their sidewalks or driveways.

Watch for signs of frostbite.
Symptoms include loss of feeling and a white or pale appearance in extremities such as fingers, toes, ear lobes or the tip of the nose.  If symptoms are detected, get medical help immediately.

Watch for signs of hypothermia
Symptoms include uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness or apparent exhaustion.  If symptoms of hypothermia are detected, get medical help immediately.

When at home:
Conserve fuel if necessary by keeping your house somewhat cooler than normal.  Temporarily "close off" heat to some rooms.
When using kerosene heaters, maintain ventilation to avoid build-up of toxic fumes.  Refuel kerosene heaters outside and keep them at least three feet from flammable objects.
