Destruction of Classified
Material
Classified material is destroyed by burning or by
pulping, provided destruction is complete and
reconstruction is impossible. Equipment that bears a
security classification is destroyed by smashing
beyond recognition. Equipment may also be jettisoned
in water of sufficient depth to prevent recovery.
Destruction bills of particular activities include
lists that show the locations of classified material,
personnel responsible for its destruction, and the
recommended place and method of destruction.
Classified material is destroyed during emergencies
when there is danger that it may be compromised.
Communication material receives first priority. Of all
communication materials, cryptographic material is
destroyed first. Generally, the order of destruction
follows the classificatione —the highest classified
material is destroyed first.
Q1l. When sent through the US. mail, Confidential
material must be enclosed in an envelope or a
container that is double-sealed to prevent what
type of problem?
Q12. In addition to burning, what other methods may
be used to destroy classified material?
SUMMARY
We discussed the physical security provided to all
mail and the Information and Personnel Security
Program as it applies to classified material sent in the
mail. We also discussed the requirements for
maintaining the security of mail and equipment,
random inspections, probable cause searches, and
what to do if a suspected letter or parcel bomb is found.
Finally, we discussed the proper destruction of
classified material.
