Cold Stress – Cold Related Illnesses

Hypothermia

When exposed to cold temperatures, your body begins to lose heat faster than it can be produced. Prolonged exposure to cold will eventually use up your body’s stored energy. The result is hypothermia, or abnormally low body temperature. A body temperature that is too low affects the brain, making the victim unable to think clearly or move well. This makes hypothermia particularly dangerous because a person may not know it is happening and will not be able to do anything about it.

Symptoms

Symptoms of hypothermia can vary depending on how long you have been exposed to the cold temperatures.

Early Symptoms

• Shivering
• Fatigue
• Loss of coordination
• Confusion and disorientation

Late Symptoms

• No shivering
• Blue skin
• Dilated pupils
• Slowed pulse and breathing
• Loss of consciousness

First Aid

Take the following steps to treat a worker with hypothermia:

• Alert the supervisor and request medical assistance.
• Move the victim into a warm room or shelter.
• Remove their wet clothing.
• Warm the center of their body first-chest, neck, head, and groin-using an electric blanket, if available; or use skin-to-skin contact under loose, dry layers of blankets, clothing, towels, or sheets.
• Warm beverages may help increase the body temperature, but do not give alcoholic beverages. Do not try to give beverages to an unconscious person.
• After their body temperature has increased, keep the victim dry and wrapped in a warm blanket, including the head and neck.
• If victim has no pulse, begin cardiopulmonary resuscitation (CPR).
