The essentials of a good first aid kit include a variety of bandages, medications, and equipment to stabilize injuries until proper medical attention can be administered.

Frostbite is seldom seen in areas with temperate climates. It occurs at sub-zero temperatures or at temperatures just below freezing but with a wind (wind chill). At some temperatures frostbite can occur within minutes. Note the blistering and swelling caused by tissue freezing. Sever frostbite may result in loss of fingers and toes or other exposed body parts.

Frostbite occurs when the skin and body tissues are exposed to cold temperature for a prolonged period of time. Hands, feet, noses, and ears are most likely to be affected. If the blood vessels in the frostbite areas are affected, permanent damage can occur. Damage to the blood vessels causes death of the tissue it supplies. Tissue death may necessitate amputation of the affected area.
