If you suspect hypothermia, monitor your condition or that of your co-workers, even after you have left work. Proper clothing and adequate insulation work together to trap the warm air around the body. Life jackets and immersion survival suits can keep you warm longer and give you the extra time you need to survive Canada's cold waters. The basic principle for preventing hypothermia on land or water is to stay warm and dry and be prepared for a sudden emergency. Guidelines that work Wear warm head covering.
Most body heat is lost through the head.
Wear layered clothing. Layers allow warm air to stay trapped but do not trap perspiration next to the skin. The first layer of clothing should allow the skin to breathe by allowing sweat to escape. Underwear, socks, and glove liners made of polypropylene or knitted silk allow sweat to escape from next to the skin. The second layer of insulating clothing should be one that absorbs perspiration but does not allow heat to escape.
