TM 5-349 contains information on arctic construction which will be important to organizations in
planning water point layout, constructing protective sheltering, and providing heat for protection of
equipment and personnel.
2-12. OPERATION IN EXTREME COLD.
a.
Inspection.
(1)
Bolts and nuts. Inspect for loose or broken bolts, nuts and other metal parts. Extremely low temperatures
reduce shock resistant property of metals and decreases their resistance to strain.
(2)
Electrical connections. Check all electrical connections on the equipment to see if they are tight and free
of moisture around the connections with a soft absorbent cloth.
b.
Location. Locate the equipment where advantage can be taken of existing shelter and windbreaks. Park the
truck and trailer on planking or other solid footing to prevent the tires from freezing to the ground. Release the brakes
and drain all air from the airbrake system. Install the other equipment on platforms of wood or other suitable material to
prevent it from freezing to the ground.
WARNING
Do not touch metal parts with bare hands when the temperature is extremely low.
c.
Shelter and Protection Against Freezing. Construct windbreaks around the installed equipment that is not In the
van body and erect tenting shelters for protection. The filtered water storage tanks may be installed inside a tent or other
shelter. All hose lines external to the shelter must be drained quickly during freezing temperatures or a flow of water
approximately 25 gpm through a 1 2 Inch hose should be maintained. Filtered water may be recirculated with the
distribution pump between the two filtered water storage tanks to prevent freezing In the hose lines, tank outlets, and
pump.
