Phyllis,

Military vaults have drains and ventilation.  It is important to have check
values to prevent back follow and ventilation to prevent mildew and mold.
Remember if you run a dehumitifer or any other eletrically devices for that
matter don't forget the ozone principle.  Electric motors and transformers like
those found in flourencent lights give up small amounts of ozone, in small or
confined spaces, ozone will attack and breakdown certain plastics and rubbers.
