If no shelter is nearby, prepare a wind break or snow cave for
protection.
Build a fire for heat.
Do not eat snow as it will lower your body temperature.
IN A VEHICLE:
Stay in your vehicle!!!
Run the motor for ten minutes every hour, but open the windows
slightly to allow for proper ventilation. Make sure the exhaust
pipe is free of snow.
Make yourself visible to rescuers by turning on the dome light at
night when running the engine. Also tie a red or other bright
colored cloth to the antenna or door.
Exercise from time to time to keep the blood circulating and to keep
warm.
AT HOME:
Stay inside. Make sure you provide proper ventilation when
using alternate heat sources.
If you have no heat, close off unneeded rooms and place towels under
the doors.
Eat to supply heat...and drink to avoid dehydration.
Wear layers of loose-fitting, light-weight, warm clothing.
