dependents. For the purposes of these standards, family housing will be considered to
include Morale, Welfare, and Recreation housing (cottages) of similar occupancies.
Force Protection Condition (FPCON). A DoD-approved system that standardizes the
Departments' identification and recommended preventive actions and responses to
terrorist threats against U.S. personnel and facilities. This system is the principle means
for a commander to apply an operational decision on how to protect against terrorism
and facilitates inter-Service coordination and support for antiterrorism activities.
Glazing. The part of a window, skylight, or door assembly that is transparent and
transmits light, but not air.
High occupancy family housing. Family housing with 13 or more units per building.
Inhabited building. Buildings or portions of buildings routinely occupied by 11 or more
DoD personnel and with a population density of greater than one person per 40 gross
square meters (430 gross square feet). This density generally excludes industrial,
maintenance, and storage facilities, except for more densely populated portions of those
buildings such as administrative areas. The inhabited building designation also applies
to expeditionary and temporary structures with similar population densities. In a
building that meets the criterion of having 11 or more personnel, with portions that do
not have sufficient population densities to qualify as inhabited buildings, those portions
that have sufficient population densities will be considered inhabited buildings while the
remainder of the building may be considered low occupancy, subject to provisions of
these standards. An example would be a hangar with an administrative area within it.
The administrative area would be treated as an inhabited building while the remainder
of the hangar could be treated as low occupancy. (Note: This definition differs
significantly from the definition for inhabited building used by DoD 6055.9-STD and is
not construed to be authorization to deviate from criteria of DoD 6055.9-STD.)
Level of protection. The degree to which an asset (person, equipment, object, etc.) is
protected against injury or damage from an attack.
Low occupancy building. Any building or portion of a building occupied by fewer than
11 DoD personnel or with a population density of one person per 40 gross square
meters (430 gross square feet) or less.
Mail room. A facility operated by or for the DoD for the receipt and delivery of mail for
military units or other authorized organizations and agencies by entities outside the
DoD. This does not include mail rooms that receive mail distribution that was initially
received at a central DoD mail handling facility.
