What is wind chill temperature? Its the temperature that it feel like outside based on the temperature of the air plus the wind speed and its effects on exposed skin. Wind chill can not effect inanimate objects such as water pipes. Below is a wind chill chart devolved by The National Weather service. It gives us information on how long you can be out in the cold and how long it takes to get frost bite given a certain temperature and wind speed. As you can see with the temperatures we had in the last week with lows near -20 below and wind chills in the -30 to -40 below it does not take long to develop frost bite. The best way to protect your self from frost bite is not to go outside for prolonged periods of time when the temperature is this cold. If you have to go out dress in layers, cover exposed skin and cover your mouth to protect your lungs from the extreme cold.
