Tag-out logs are used to control the entire tag-out
procedure. The number of tag-out logs required
depends on ship size. For example, a minesweeper may
only require one tag-out log for the whole ship, while a
major surface combatant may require a separate log for
each department. Individual force commanders specify
the number of logs various ship classes must maintain
and what areas of the ship must maintain them.
On ships maintaining more than one tag-out log,
authorizing officers must exchange information on
tag-out actions. When a tag-out affects other
authorizing officers, the initiating party obtains verbal
permission from those officers to tag out the system or
equipment in question before the tag out is authorized.
Examples of systems that may require such
coordination are ship service electrical distribution,
hydraulics, air, ventilation, and air-conditioning chill
The tag-out log is a record of authorization of each
effective tag-out action. It contains the following
1. A copy of the main instruction and any other
amplifying directives for administering the
system. These documents are kept in the front of
2. A DANGER/CAUTION tag-out index and
record of audits (index/audit record). The
index/audit record provides a sequential list of
all tag outs and ensures serial numbers are
sequentially issued. They are used in audits of
the log as well to provide a ready reference of
existing tag outs. The cognizant department
head may remove the index pages with all tag
outs listed as cleared.
3. Cleared DANGER/CAUTION tag-out record
sheets that have been cleared and completed.
These sheets are kept in the log until received
and removed by the cognizant department head.
Tags in a common system (for example, ships radar
or a fire-control system) are logged on one
DANGER/CAUTION tag-out record sheet. Subsequent
sheets on the same system are kept together.
