UNUSUAL ENVIRONMENT/WEATHER
Refer to this work package for steps and precautions to take in the even of adverse or unusual
environmental conditions.
Operation in Heavy Rain or Flooding
Ensure that all tent lines and frame feet are staked.
Frequently check all tent pins and lines. Tent lines may shrink from dampness, so keep tent lines
loose enough to prevent tent pins from being pulled out of the ground.
Check all seams and joints for proper fit and potential leakage.
Close and fasten all windows and doors.
Dig a trench around the perimeter of the tent or tent complex.
Disconnect power if leaks occur.
Operation in Extreme Moist Heat
Ensure all entrances and openings are secure if an ECU is employed.
If no ECU is available, allow for as much ventilation as operating conditions will permit. Wall fabric
may be rolled up or removed if permissible by mission requirements. If tent walls are rolled up,
ensure that the wall is rolled up inside the tent to prevent accumulation of moisture in tent fabric.
Tent lines may shrink from dampness, so keep tent lines loose enough to prevent tent pins from
being pulled out of the ground.
Ensure that tent fabric has an opportunity to thoroughly air out and dry as soon as practical in order to
prevent mildew.
Operation in Extreme Dry Heat
Ensure all entrances and openings are secure if an ECU is employed.
If no ECU is available, allow for as much ventilation as operating conditions will permit. Wall fabric
may be rolled up or removed if permissible by mission requirements. If tent walls are rolled up,
ensure that the wall is rolled up inside the tent to prevent accumulation of dust or dirt in tent fabric.
Operation in Extreme Cold
If ground is frozen too hard to drive steel tent pins, chop small holes to set them in. Fill holes with
slush or water and allow to freeze and anchor pins.
Close and fasten all windows and doors. An external or internal heater must be employed.
Ensure no ice or snow accumulates on tent roof or in gutters.
Operation in Salt Air or Sea Spray
Frequently check all tent pins and lines. Tent lines may shrink from dampness, so keep tent lines
loose enough to prevent tent pins from being pulled out of the ground.
Check all seams and joints for proper fit and potential leakage.
Close and fasten all windows and doors.
Dig a trench around the perimeter of the tent or tent complex.
Disconnect power if leaks occur.
Ensure all components are rinsed with fresh water as soon as often as practical, and before preparing
