Dangerous wind chills have cancelled school in Sioux Falls, Brandon and some surrounding schools.  Wind chill values are expected to dip to 35 to 40 below zero Thursday and remain below zero on Friday.

The Sioux Falls Fire and Rescue has the following safety tips for citizens:

  • Do not venture out if you do not have to. If you do need to go out, limit your exposure and know your limitations. Dress in several layers and wear a waterproof and/or windproof outer layer.
  • Fingertips, earlobes, and noses tend to be highly susceptible to frostbite. Keep these areas covered while out in the cold weather. The body loses approximately 40 percent of its heat through the head. Wearing a hat will help conserve body heat.
  • Frostbite is a serious condition caused by long exposure to the cold. If left untreated, this may result in the actual freezing of an extremity, digit, or nose. DO NOT ATTEMPT TO REWARM A FROSTBITTEN EXTREMITY BY RUBBING IT. Rewarming must be done gradually and in an emergency department.
  • The very young and elderly tend to be prone to cold‑related injuries. It is important to monitor children and to regularly check on elderly relatives or neighbors.
  • If you anticipate being out in the elements for an extended period of time, do not smoke or consume alcohol. These items cause changes in the circulatory system making the body even colder.
  • Make sure you have a working smoke detector in every bedroom and on every level. Check and change the batteries often.
  • Make sure that electric heaters and blankets are U.L.‑ or F.M.‑rated, and kept away from any combustible materials such as draperies and linens. Unplug electric blankets and portable electric heaters when not in use. Ensure they are operating safely and correctly.
