Damage Control Closure
The closure log is maintained at all times, whether
the ship is in port or under way. The closure log is used
to show the following:
The location where the existing material
condition of readiness has been modified
The type, number, and classification of the
fitting; the name, rate, and division of the person who
requested permission to open or close the fitting
The date and time the fitting was opened or
closed; the date and time the fitting was returned to its
specified material condition of readiness setting
The name and rate/rank of the person granting
The commanding officer prescribes the limit to
which the DCA or OOD may approve the modification
of a material condition of readiness. Reporting the
temporary closing of a fitting that should be open is just
as important as reporting the opening of one that should
be closed. For example, a ZEBRA watertight hatch that
is secured at the time general quarters is sounded could
seriously interfere with personnel trying to get to their
The damage control closure log is normally kept on
the quarterdeck in port, on the bridge at sea, and in
damage control central (DCC) during general quarters.
However, if your ship has a 24-hour watch in DCC at all
times, the closure log will be kept there regardless of the
ships location. The closure log is updated when there is
a change in the status of a classified closure or fitting. If
a classified closure is to remain open for several days, it
must be logged open each day. The maximum time a
closure or fitting may be logged open is 24 hours.
