When Mother Nature whips up a wicked winter wind-chill factor it creates a real health risk for outdoor workers if they don’t take precautions against what OSHA calls “cold stress”: hypothermia, frostbite, and trench foot—a nonfreezing injury to wet, cold feet.
Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin.
The following frequently asked questions — answered by OSHA — will help workers understand what cold stress is, how it may affect their health and safety, and how it can be prevented.
