District Issues Protective Actions for Extreme Cold Extreme cold consist of temperatures significantly colder than normal. Extremely cold conditions can cause a number of health and safety concerns, including frostbite, hypothermia, carbon monoxide poisoning and fires (from alternative heating sources). In general, if you are experiencing extremely cold conditions you should: Be aware of the fire danger from space heaters and candles; keep such devices away from all flammable materials. Install recommended smoke and carbon monoxide detectors (at least one of each per floor in your home). Stay indoors and use safe heating sources. Indoors, do not use charcoal or other fuel-burning devices, such as grills, that produce carbon monoxide.  Outdoors, stay dry and in wind protected areas. Wear several layers of loose fitting, lightweight, warm clothing rather than one layer of heavy clothing. Wear mittens, a hat and cover your mouth with a scarf to protect your lungs. Drink plenty of non-alcoholic fluids and eat high-caloric foods.  Watch for signs of frostbite-- Skin appears white and waxy, numbness or no feeling in that area and/or possible blisters. Watch for signs of hypothermia-- Shivering and numbness, confusion or dizziness, stumbling and weakness, slow or slurred speech and shock.  If you or someone you know is experiencing signs of hypothermia or frostbite go to a medical facility immediately.  Call the Hypothermia Hotline at (800) 535-7252 if you see a homeless person stranded in the cold. Vans will transport homeless individuals to a shelter.
