USIB POLICY STATEMENT
ESTABLISHING
PHYSICAL SECURITY STANDARDS FOR SENSITIVE
COMPARTMENTED INFORMATION* FACILITIES
(Effective 30 April 1973 )
Minimum standards are hereby established governing the
construction and protection of facilities for storing and processing
sensitive compartmented information and material which requires
extraordinary security safeguards as prescribed in pertinent
national directives. Compliance with these standards is mandatory
for all facilities established after the effective date, above,
including any major renovation of existing facilities insofar as
the renovation will permit reasonable and practical upgrading.
It is not intended that existing, previously approved facilities shall
be modified to conform with these standards.
It is recognized that there may be instances in which
circumstances constitute a threat of such proportion that it can
*The term "sensitive compartmented information" as used in this
Directive is intended. to include all information and materials bearing
special community controls indicating restricted handling within
present and future community. intelligence collection programs and
their end products for which community systems of compartmentation
have been or will be formally established. The term does not
include restricted data as defined in Section II, Public Law 83-703,
Atomic Energy Act of 1954, as amended.

only be offset by the most stringent security arrangements.
Conversely, there may arise those instances in which time,
location, condition of use of the material, or other unforeseen
factors may render full compliance with these standards
unreasonable or impossible. Situations such as the foregoing
are to be referred to the cognizant approving authority as far
in advance as possible in order that full and timely consideration
may be given to a request for deviation from the standards.
The procedures for establishment and accreditation of
sensitive compartmented information facilities shall be as
prescribed in the applicable national directives.

of the perimeter wall, floor, or ceiling of the facility is also a part
of the building perimeter, such a wall, floor, or ceiling must be
constructed to the secure area specifications in Annex B. The
facility, including its openings, shall be protected with an approved
perimeter or volumetric alarm system. The alarm system must
cover the entire area of the facility to include an area above a
false ceiling. The door(s) to the facility must be of metal or solid
wood and equipped with a permanently installed GSA approved
Group 1 combination :Lock with an escape mechanism, such as the

 Approved For 6)20A d 4AL P8 1MOck591 ?0400050013-0
in an area particularly subject to burglarious attack or mob
violence, bars or shutters should be used on the windows instead
of or in addition to alarms, depending on the degree of
vulnerability existing in the area. Doors to the facility should
be kept to a minimum., ideally one. Flat sill fire doors with
built-in locking mechanisms, solid wooden doors (1-3/4"
minimum thickness), or metal clad fire doors should be used.
Doors must be equipped with a permanently mounted GSA
approved Group 1 combination lock and have an inside escape
mechanism such as the Safemasters Model 50 Lock Extension.
An approved alarm door switch must be used on all doors in
addition to the lock. If secondary doors are required, they should
be of the type mentioned above or of sheet steel (without frontal
hardware) and secured from the inside with bars and brackets
or lockable sliding deadbolts (see Annex E for example). Guard
patrols within or around the facility should be on a random basis,
but not less than two times each hour. If there is no guard
patrol available, then. the room and/or containers and the doors
and windows are to be equipped with approved alarms, with the
guard response being five minutes or less.

requirements. However, if any part of the perimeter wall, floor,
or ceiling of the facility is also a part of the building perimeter,
all windows and doors in such part shall be protected against
forced entry as described in Paragraph 13. b. , above. The wall,
floor, or ceiling in that part shall be constructed of material
that provides equivalent forced entry protection. Adequate
guard personnel shall be available to respond to the facility in
the event of an emergency.
d. Secure Working Areas (no storage of compartmented
intelligence): Perimeter walls, floors, and ceilings may be
constructed without regard to the thickness or type of material so
long as they are of such strength that they will show evidence of
any attempt at forced entry and provide the necessary sound
attenuation. However, where there exists a possibility that
undetected penetration (i. e. , surreptitious entry) can occur, then
appropriate measures must be taken (e. g. , alarms, barriers,
etc.) to detect and/or prevent it.

SECTION III - SECURITY ALARM SYSTEMS
18, It is recognized that the requirement for a security alarm
system is dependent on a number of variables. The physical
location of the facility, number and type of guards, hours of
operation, type of construction, and the degree of the threat must
all be considered when deciding if, and/or what type of, an alarm
system is to be used. However, if an alarm system is used,
it must meet the minimum requirements established herein.
19. Any security alarm system or alarm component which is to
be used to protect sensitive compartmented information must
have been tested against, and passed, the Interim Federal
Specification, Alarm Systems, Interior, Security, Components
for, W -A-00450A (GSA-FSS) dated Z9 December 1969, as
subsequently amended. The Atomic Energy Commission (AEC)
is the General Services Administration's officially designated
test facility for security alarm systems. Their certification that
a system or a component has been tested against the Interim
Federal Specification and has passed all tests shall constitute an
authorization to use that system or component to protect sensitive
compartmented information.

20. The use of Types 1, 2, or 3 alarm transmission line
supervision, as defined in the Interim Federal Specification,
shall be in accordance with the following conditions:
a. When the alarm transmission lines do not leave the
perimeter of the facility, electronic line supervision is not
required.
b. When the alarm transmission lines do not leave the
perimeter of the building housing the facility, transmission lines
may be routed in tubing (EMT, joints epoxy sealed) and equipped
with a Type 3 electronic line supervision system; or the transmission
lines may be protected by a Type 1 or 2 electronic line supervision
system not routed in tubing, in lieu of a Type 3 line supervision
system routed in tubing.
c. Transmission lines routed in an environment not covered
above must be protected with a Type 1 or 2 electronic line super-
vision system, or, may be routed in steel conduit and protected
by a Type 3 line supervision system.

TELEPHONE AND INTERCOMMUNICATIONS EQUIPMENT SECURITY
PART I - TELEPHONE SECURITY
22, To achieve the required degree of telephone security for a
sensitive compartmented information facility, controls must be
placed on all telephone lines, active or inactive, and telephone
instruments must be kept to a minimum and correctly safeguarded
to prevent their being employed as clandestine listening devices.
Z3. All incoming telephone cables and wires which penetrate a
facility's perimeter must enter the facility through one opening
and be placed under control at the interior face of the perimeter
by the following:
a. All active incoming telephone lines must be accounted
for by the number of pairs in use, by telephone or extension
number, and the number of excess/unused pairs in existence.
This accounting must be updated whenever the status of a pair of
wires is changed.
b. All excess/unused incoming wires must be either
disconnected, removed, stripped and grounded, or bound together
in a manner which prevents their unauthorized use.

24. The United States Intelligence Board has authorized the
publication and dissemination of telephone security guidance
developed by its Technical Surveillance Countermeasures Committee
(TSCC). The installation of telephone equipment in sensitive
compartmented information facilities shall be in accordance with
TSCC telephone security guidance publications.
PART II - INTERCOMMUNICATIONS EQUIPMENT
25. The installation of intercommunications systems in these
facilities is discouraged; but, if they are needed for operational
purposes, they will be installed in accordance with the guidance
he rein.
26. If a dial-type intercommunications system capability is
engineered into the approved telephone system, no further action
is required under this paragraph, providing that the system is in
accordance with Part I, Section IV, above. If a separate internal
intercommunications system or a direct wire telephone intercom
is installed, the following must be complied with:
a. No station or wiring will be located outside of the facility,
and all wiring will be installed in a manner that permits visual
observation of the complete wire runs.

MISCELLANEOUS PHYSICAL SECURITY REQUIREMENTS
27. Audio Security: In establishing physical security protection
for a sensitive compartmented information facility, sound
attenuation aspects, as well as the possibility of technical
penetration, must be considered. Countermeasures can be effected
by installation of proper equipment, suitable construction, and
enhanced by the maintenance of sound discipline where required.
When conversations of a classified nature occur within a facility,
sound deadening material must be installed so as to conform

These classifications apply to all perimeter walls, floors,
ceilings, doors, windows, vents, ducts, and any other openings
exposed to areas not under U. S. Government control or areas
which otherwise present a hazard. A technical counter audio
inspection shall be conducted at each new facility either before it
is placed in operation or as soon afterward as is possible.
Thereafter, these inspections shall be conducted at such intervals
as may be necessary to maintain adequate technical security.

materials, all windows which might reasonably afford optical
surveillance of personnel, documents, materials, or activities
within the facility must be made opaque or equipped with blinds,
drapes, or other suitable covering which will preclude such
optical surveillance.
29. Access Controls: Rooms, office suites, or other areas
accredited as sensitive compartmented information facilities
must be afforded access controls to preclude freedom of entry
by unauthorized personnel during the conduct of business.

30. Security Standards for field or combat operations can only
prescribe the minimum requirements, since each situation
differs. Situation and time permitting, however, the minimum
standards below will be improved upon, using the security
considerations and requirements for permanent secure facilities
as an ultimate goal.
31. Under field or combat conditions, a continuous 24 hours
operation is mandatory. Every effort must be made to obtain all
necessary support from the headquarters served (e. g. , security
containers, vehicles, generators, barbed wire, automatic
weapons, etc. ).
32. Recognizing that field/combat operations, as opposed to
operations within a fixed military installation, are of the type
which may be considered as least secure, it is, therefore, required
that the following minimum physical security requirements be met:
a. The facility shall be physically located well within the
supported headquarters defensive perimeter; preferably as close
to the Command Operations Center as compliance with these
requirements will allow.

b. The facility will be fenced with a triple strand concertina
fence erected a minimum of 10 yards from the facility.
c. Access into the area will be restricted to a single
gate/entrance capable of being secured.
d. The gate/entrance will be manned by a guard during the
hours of darkness.
e. The gate/entrance will be secured at all times except
when required to be opened for movement of personnel and
equipment.
f. Where resources permit, a minimum of two indoctrinated
personnel will be within the facility at all times.
g. A current access list will be maintained and access to
the facility will be restricted to those persons whose names appear
on the list.
h. Emergency destruction and evacuation plans will be
kept current.
i. When not in use, material will be stored in GSA approved
containers.
j. Communications, both wire and radio if possible, will
be established and maintained with the reserve guard forces.

33. The following requirements will be met if consistent with
tactical conditions, availability of time, resources, manpower,
and the desires of the supported commander:
a. If available, permanent type facilities will be used.
b. When temporary facilities are used, they will be
sandbagged.
c. The gate/entrance will be guarded on a continuous basis.
d. The facility perimeter fence will be guarded, during
the hours of darkness, by walking or fixed guards to provide
observation of the entire perimeter fence. Guards will be armed
with weapons and ammunition prescribed by the supported
commander.

1. These are minimum specifications. Use of materials having
thicknesses or diameters larger than those specified is optional.
The term "anchor and/or imbedded to the floor and ceiling"
applies to the affixing of supporting members and reinforcing to
the true slab or the most solid existing surface. Sub-floors and
false ceilings are not to be used for this purpose.
2. Reinforced concrete construction (for new construction and for
construction at ground level or below): Walls, floor, and ceiling
shall be a minimum thickness of 8" of reinforced concrete. The
concrete mixture shall have a minimum compressive strength of
at least 3, 000 PSI. Reinforcing shall be accomplished with
reinforcing bars a minimum of 5/8" in diameter positioned
centrally in the concrete pour and spaced horizontally and
vertically 6" on center. The bars shall be tied together in the
contiguous walls and firmly anchored to and/or in the floor and
ceiling.
3. Steel Lined Construction (for use in existing structure
and/or above ground level): Construction shall be of steel plate
a minimum of 1/4" thick. The steel plates are to be continuously

welded to supporting steel members of a minimum thickness equal
to that of the plate. If the supporting steel members are being
placed in a contiguous floor and ceiling of reinforced concrete,
they must be either firmly anchored to and/or imbedded in the
floor and ceiling. If the floor and/or ceiling construction is less
than 6" reinforced concrete, then a steel liner shall be constructed
the same as the walls to form a floor and ceiling of the vault.
4. Openings as they Apply to Both Methods of Vault Construction:
a. The vault shall be equipped with an approved vault door
of the type presently listed on the Federal Supply Schedule. The
Class 5 vault door shall be used with reinforced concrete vaults.
Where weight or construction is a factor and a steel lined vault
is used, the lighter Class 6 vault door is recommended. Normally,
a vault should have only one entrance. When a vault exceeds
1, 000 square feet of floor space or has more than 8 occupants,
it should have a minimum of two exits (one of which will be the
entrance) for safety purposes. When more than one entrance is
required, each must be equipped with the approved door, but only
one door shall be used for normal access. Doors without frontal
hardware will be used as secondary doors. The use of a vault

door for controlling daytime access to a facility is not authorized
as this continued use will create undue wear on the door and will
eventually weaken the locking mechanism and cause malfunctioning.
Therefore, a vestibule should be constructed at the entrance with
an access door which meets the sound attenuation requirements in
Annex C. Where building codes require that the vault entrance
meet a specified fire rating, the vestibule access door must be of
the required fire rating. There shall be no windows in a vault.

SECURE AREA SPECIFICATIONS
1. Secure area walls shall be reinforced on the inside with steel
plate not less than 1/8" thick. The plates at every vertical joint
are to be affixed to vertical steel members of a thickness not
less than that of the plate. The vertical members shall be firmly
anchored to the floor and ceiling. The plates shall be spot welded
to the vertical members by applying a 1" long weld every 12";
meeting of the plates in the horizontal plane shall be continuously
welded. If the existing walls are of reinforced concrete over 4"
thick, or are of solid masonry (stone or brick) over 8" thick, no
reinforcing is required. Walls of hollow masonry (blocks and
tiles) are not considered adequate and must be reinforced.
2. The floor and ceiling of the room selected for a secure area
shall be of at least 4" of reinforced concrete. Floors and
ceilings not meeting this criterion must be reinforced with steel
plate 1/8" thick. Floor and ceiling reinforcement must be
securely affixed to the walls with steel angles welded or bolted
in place.

SOUND ATTENUATION CLASSIFICATIONS
1. This Annex provides information to be used as acoustic
isolation criteria (voice range only) for construction of sensitive
compartmented information facilities. The spectrum of technical
surveillance devices for voice transmittal and compromising
emanations is treated in other directives and, therefore, is not
addressed herein.
2. The term "Sound 'Transmission Class'(STC) is used in
architectural acoustics to describe the transmission attenuation
afforded by various wall materials and other building components.
The following transmission attenuation groups have been set up
to satisfy the normal security requirements of facilities used
for sensitive compartmented information activities which border
areas not under U. S. Government control or areas which otherwise
present a hazard.
a. Sound Group 1 - 30 or better STC
Loud speech can be understood fairly well.
Normal speech cannot be easily understood.

MINIMUM SPECIFICATIONS FOR LOCALLY
FABRICATED STEEL SECONDARY OR EMERGENCY
EXIT DOORS FOR VAULTS AND SECURE AREAS
1. The door will be a, single steel panel not exceeding 4' in width
or 8' in height. The minimum panel thickness should be 1/4" for
secure areas and 1/2" for vault areas.
2. The door frame is to be constructed of steel at least 1/811
thick for secure areas and 1/4" thick for vault areas. The door
stop must be continuously welded to the frame. It may be a solid
block of metal (Detail B) or a "U" channel (Detail A); however,
the stop must extend out from the frame sufficiently to allow at
least a one inch contact with the door panel at sides and top.
The frame should extend over the wall, sides and top, a minimum
of 4".
3. Normally doors of this type must open outward for safety
reasons and, therefore, the hinges are on the outside. Heavy duty
steel hinges will be used, at least three per door panel. These
hinges should be welded to the panel and frame, and the hinge pins
welded to the butts.

location shown on the attached drawing. The top two brackets are
to be positioned approximately 1/3 of the distance down from the
top of the door panel and the bottom two approximately 1/3 of the
distance up from the floor.
5. Two steel bars are to be made (Detail C) for placement in
the brackets. The bars can be constructed of two steel angles or
"U" channels welded together and, when completed, should be
approximately 3" to 4" square. The length of the bars will be such
that, when in place, they provide a close fit in the door jamb,
overlapping the door stop/mullion by 1" or more.
6. The bars and brackets are to be drilled at a downward angle
to accommodate 1/4" steel pins. The pins are to be sufficiently
long to bottom out on the inside of the bars and are to be secured
with chains welded or otherwise attached to the door jamb;
attachment is to keep the pins from being lost. The fit of the pins
must permit ready removal by hand.
7. Spacer blocks are to be provided with each of the bar and
bracket units. These blocks serve to cause a proper, snug fit of
the bars when in place. The blocks may be of either steel or wood.
If steel, they may be welded to the bars; if wood, they may be
drilled and attached with bolts.

8. Detail A depicts a means of securing a door frame to a light
secure area type wall, such as wood studs and dry wall reinforced
with steel or expaned metal. A "U" channel or two angles are
adjusted and welded together to form the frame around the wall
opening. It is then bolted in place by the use of carriage bolts
having their rivet-like heads on the outside and the nut on the inside.
The bolts at the nut end will be peened over or spot welded to
preclude tampering. The bolts should be at least 3/8" in diameter
and installed so that their heads fit tight and flush against the
outside of the frame. Bolts will be installed in both sides and
top of the frame and spaced approximately 18" apart.
9. Detail B depicts a suggested method for installing a frame in
a masonry wall. Pieces of steel 1-1/2" to 2" wide by 1/4" thick
are formed as shown and grouted into the masonry of the door
opening every 12" to 18" at both sides and top. The hole in the
end, kept flush with the opening, will be drilled and tapped to
receive the screw selected. This screw should be of steel, 3/8"
or more in diameter, and will be long enough to extend through
all three pieces of metal. Two angles, as shown in the detail,
are then put in place and screwed together. The door stop, be it

a solid block or "U" channel, is then continuously welded in place
on both sides and top of the frame. This method of installing a
steel door frame is extremely effective from the standpoint of
strength. If the steel piece is not used, a 3/8" diameter steel lag
bolt, shaped in an L, may be grouted into the masonry with its
threaded end out. The two angles are then installed with holes to
permit the threaded end to protrude through them and a nut is
used to bolt the frame in place. This method is as effective, but
is more unsightly and personnel passing through the door are apt
to catch clothing on the protruding bolt ends.
