Classified information or material is used only
where facilities or conditions are adequate to
prevent unauthorized persons from gaining access
to it. The exact nature of security requirements
depends on a thorough security evaluation of local
conditions and circumstances. Chapter 13 of OP-
NAVINST 5510.1H contains specific details for
safeguarding classified material.
Responsibility for Safeguarding
If you have possession of classified material,
safeguard it at all times. Lock it in appropriate
security equipment whenever the material is not
in use. Follow procedures that ensure unauthorized
persons cannot gain access to the classified
information by sight, sound, or other means.
Never discuss classified information with or in the
presence of unauthorized persons.
When working with Top Secret information,
observe the two-person rule. That rule requires
two persons to handle Top Secret material.
However, the rule allows one person to be left
alone with the material for a short period of time
during normal working hours.
Remove classified material from a designated
office or working area ONLY in the performance
of your official duties. Remove classified material
from designated areas to work on it during off-
duty hours, or for any other purpose, ONLY with
specific approval of the Chief of Naval Opera-
