Safety Information

It is important to have a safety kit both at home and in the car that can be used not only in winter weather situations but also for other emergencies. Ready Georgia provides a list of items to include in your emergency kit. The following safety tips are provided by the National Oceanic and Atmospheric Administration (NOAA), the Federal Emergency Management Agency (FEMA) and the American Red Cross. More information can be found in Winter Storms: The Deceptive Killers.

If caught outside in a winter storm:

  • Try to find a shelter.
  • If no shelter is available:
    • Try to stay dry.
    • Cover all exposed body parts.
    • Build a fire for heat and to attract attention.
If stuck in a vehicle during a winter storm:
  • Stay in your vehicle.
  • Run the motor about 10 minutes each hour for heat.
  • Open the window a little for fresh air to avoid carbon monoxide poisoning.
  • Turn on the dome light at night when running the engine to be visible to the rescuers.
  • Tie a colored cloth, preferably red, to your antenna or door.
  • After snow stops falling, raise the hood to indicate you need help.
  • From time to time, move arms, legs, fingers and toes vigorously to keep blood circulating and to keep warm.
If inside during a winter storm:
  • Stay inside!
  • When using alternate heat from a fireplace, wood stove, space heater, etc. use fire safeguards and properly ventilate.
  • If there is no heat:
    • Close off unneeded rooms.
    • Stuff towels or rags in cracks under doors.
    • Cover windows at night.
    • Eat and drink. Food provides the body with energy for producing its own heat. Keep the body replenished with fluids to prevent dehydration.
    • Wear layers of loose-fitting, lightweight, warm clothing. Remove layers to avoid overheating, perspiration and subsequent chill.
Health Hazards

Frostbite and hypothermia are two health hazards associated with cold weather. According to NOAA's Winter Storms: The Deceptive Killers handout, frostbite is damage to body tissue caused by extreme cold. A wind chill of -20°F will cause frostbite in just 30 minutes. Frostbite causes a 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! If you must wait for help, slowly rewarm the affected areas. However, if the person is also showing signs of hypothermia, warm the body core before the extremities.

In NOAA's Winter Storms: The Deceptive Killers it is discussed how hypothermia is a condition that can kill and is brought on when the body temperature drops to less than 95°F. Warning signs include uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness and apparent exhaustion. Take the person's temperature and if below 95°F, seek medical care immediately.
