TM 10-4610-243-13 Section IV. OPERATION UNDER UNUSUAL, CONDITIONS 2-16. OPERATION IN EXTREME COLD (BELOW 32° F (0°C)). a. When the air temperature is expected to be 32°F (0°C) or below, set up the water system using the minimum number of components required to accomplish your mission. b. Observe the following precautions when operating the water system in extreme cold: (1) Wear arctic mittens and rubber gloves when handling hardware. Bare hands can freeze to metal components. Change mittens if they get wet. (2) Take advantage of existing shelter and windbreaks during system installation. (3) Erect tents or shelters for protection. The collapsible tanks must be installed inside a tent or other shelter when temperature falls below freezing. Fuel, coal or wood burning heaters or other heating devices may be installed inside the erected tents to protect the equipment and prevent freezing of water. (4) Do not operate heater in fuel vapor areas or areas lacking adequate ventilation. Inhalation of fumes will result in serious illness or death. (5) Avoid unnecessary folding, unfolding or rolling of tank in freezing temperatures. Cracks can develop in tank fabric. (6) Remove snow, sleet or ice from water tanks Be careful to prevent cracking of tank fabric. (7) Turn valve control handles slowly during cold weather. Internal seals may have become stiff and brittle. (8) Remove snow, sleet or ice from quick disconnect couplings before making connections. (9) Recirculate water between collapsible fabric tanks to help prevent freezing. (10) When not in use, store water hoses and tanks in a heated area to avoid freezing. If frozen, disconnect hoses and move them to a heated area until they thaw. (11) Refer to the applicable TM for operating the 350 GPM pump in extreme cold. (12) Refer to the applicable TM for operating the 125 GPM pump in extreme cold. (13) Refer to the applicable TM for operating the hypochlorination in extreme cold. (14) Refer to the applicable TM for operating the collapsible fabric tanks in extreme cold. (15) Monitor water system during operation for split, clogged or frozen hoses. 2-93
