Prevention
C
- Cleanliness and Care - Feet, socks, and clothing are warmer when clean.
Proper care of the feet is imperative.
O
- Overheating - Wearing too much clothing causes overheating, perspiration,
dampness, and coldness.
L
- Layers and Looseness - Clothing in loose layers assures air spaces which
hold body heat. Adjust the number of layers to the temperature and
activity. Loose-fitting clothing insures circulation and insulation.
D
- Dampness - A wet garment is a cold garment. Wear the field jacket as a
windbreaker and to repel water.
First Aid and Treatment
Get off your feet, change to
warm, dry clothing, and seek medical assistance. DO
NOT RUB, AND DO NOT USE SNOW!
