What is the extreme cold weather temperature range described for CHS operations?

• A. -80 to -100 along with gale force winds
• B. -20 to -40
• C. 0 to -10
• D. -50 to -70

Answer: (A)

Extreme cold weather operations demand planning for conditions where temperatures are extremely low and wind chill from gale-force winds makes the environment even more dangerous. For CHS operations, the described extreme cold range is minus eighty to minus one hundred degrees, with gale-force winds. This range captures the level at which human physiology, equipment performance, and field logistics are pushed to the limit, increasing risks such as frostbite and hypothermia, rapid deterioration of batteries and fuel, and the need for heated shelters and rapid evacuation capabilities. The other temperature ranges are far less severe and do not represent the conditions that define CHS planning in extreme cold, which is why this range is the best fit.
