3. Engineering officer of the watch (EOOW)This
individual may be either the EOOW or the EDO,
depending on engineering plant conditions.
4. Officer of the deck (OOD)This individual may
be either the OOD or the ships duty officer, depending
on the ships condition.
5. CAUTION tag (See fig. 1-6.)This is a
YELLOW tag used as a precautionary measure. It
provides temporary special instructions or warns that
unusual caution must be used to operate the equipment.
These instructions must state exactly why the tag is
installed. Use of phrases such as DO NOT OPERATE
WITHOUT EOOW PERMISSION is not appropriate.
Yellow tagged equipment or systems must not be
operated without permission from the responsible
supervisor. The CAUTION tag may not be used if
personnel or equipment can be endangered while
working under normal operating procedures. In such
cases, a DANGER tag must be used.
6. DANGER tag (See fig. 1-7.)This is a RED tag
that prohibits the operation of equipment that could
jeopardize the safety of personnel or endanger
equipment, systems, or components. Equipment may
not be operated or removed when tagged with
7. OUT-OF-CALIBRATION labels (See fig.
1-8.)These are ORANGE labels used to identify
instruments that are out of calibration and do not give
accurate readings. These labels warn that the
instruments may be used for system operation, but only
with extreme caution.
8. OUT-OF-COMMISSION labels (See fig.
1-9)These are RED labels used to identify instruments
that will not give accurate readings because they are
either defective or isolated from the system. The
instruments should not be used until they have been
recertified for use.
9. Repair activityThis is any activity other than
the ships force that is involved in the construction,
testing, repair, overhaul, refueling, or maintenance of
the ship (intermediate or depot level maintenance
10. Ships forceThese are personnel who are
assigned to the ship and are responsible for the
maintenance and operation of the ships systems and
equipment. Only qualified personnel are authorized to
make a tag-out.
11. Tag-out logThis is the control document used
to administer the entire tag-out procedure.
Figure 1-8.Out-of-calibration label.
Figure 1-9.Out-of-commision label.
The number of tag-out logs on a ship depends on the
ships size. For example, a minesweeper or
nonnuclear-powered submarine may need only one
tag-out log; a major surface combatant may need a
separate log for each major department. Individual force
commanders specify the number of logs needed and
A tag-out log is a record of authorization for each
tag-out action. It includes the following information:
1. A copy of OPNAVINST 3120.32B and any
amplifying directives needed to administer the system.
2. The DANGER/CAUTION Tag-out Index and
Record of Audit (Index/Audit Record). This is a
sequential list of all tag-outs issued. It provides a ready
reference of existing tag-outs, ensures that serial
numbers are issued sequentially, and is useful in
conducting audits of the log. A sample of this index is
shown in figure 1-10. Index pages with all tag-outs listed
as cleared may be removed by the department head.
3. DANGER/CAUTION Tag-out Record Sheet
(figs. 1-11 and 1-12). All tags that have been used in the
tag-out of a particular system are logged on one
DANGER/CAUTION tag-out record sheet along with
the reason for the tag-out. All effective sheets are kept
in one section of the log.
4. Instrument Log (fig. 1-13). Labels used with
OUT-OF-CALIBRATION and OUT-OF-COM-
MISSION instruments are logged in the instrument log.
5. Cleared DANGER/CAUTION Tag-out Record
Sheets. Sheets that have been cleared and completed are
