repairs or maintenance. The authorizing officer has the
authority to sign tags and labels and the authority to
cause tags and labels to be issued or cleared. The
authorizing officer is always the officer responsible for
supervising the tag-out log. The CO designates
authorizing officers by billet or watch station.
Repair Activity Representative
If a tag out has been requested by a repair activity, a
representative (shop supervisor or equivalent) signs the
tag-out record sheet. This persons signature indicates
repair activity satisfaction with completeness of the tag
out. The repair activity representative should check and
sign each tag that has been hung as he or she makes sure
each system is completely isolated. Only after taking
that safety precaution should the representative sign the
tag-out record. When verified, the tags alert personnel
that the repair activity must approve removal of the tags.
The repair activity representative approves removal of
the tags by signing a tag-out sheet stating that the work
is completed and no more work is to be done on the
Person Attaching the Tag
The person who attaches the tag (along with the
person who second-checks the tag) can make or break
the tag-out system. The person hanging the tag actually
shuts a valve or secures a switch that takes a piece of
equipment off line for repairs or maintenance. When
you secure a switch or shut a valve, you hang the danger
or caution tag securely so that it wont fall off, then you
sign it. By signing the danger or caution tag, you verify
that you have secured the items that need to be secured
and that they are secured.
Person Checking Tag
As you know, the person checking the tag is an
important person in the tag-out procedure. The process
of checking a tag or label is called second-checking. The
second-checker examines the tag or label to make sure it
corresponds to the equipment that is supposed to be
secured and checks the position of the switch or valve. If
no mistakes are found, the second-checker signs the tag
or label. The signature tells everyone concerned that all
is okay with the tag or label and that the equipment is
secured. If the second-checker finds something wrong,
he or she notifies the first person (person attaching the
tag) and the authorizing officer that somethings wrong.
The person who tags a system and the second-checker
have a big responsibilitythe lives of their shipmates as
well as their own rely on how well they do their jobs.
TAGS, LABELS, AND LOGS
The various tags, labels, and logs used in the tag-out
system have a definite purpose. The tags and labels
indicate the equipment is out of order or unable to
perform its normal functions. These tags are red and
yellow, and both are used as warning tags.
A red tag means a certain DANGER exists if the
valve or equipment lineup is changed.
A CAUTION tag is yellow and usually has a set
of instructions printed on it about the operation
of the equipment.
Two labels are associated with the tag-out
systemthe OUT-OF-COMMISSION(red) and
OUT-OF-CALIBRATION (orange) labels.
The tags, labels, and logs used in the tag-out system
help to ensure personnel safety. Lets look at how you
use each of them.
Use a yellow CAUTION tag, NAVSHIPS 9890/5
(fig. 19-5), as a precautionary measure to provide
temporary special instructions or to show personnel that
they must use extra caution in operating equipment. In
the instructions, state the specific reason for the tag.
Dont use phrases such as Do not operate without
EOOW permission. Personnel dont operate
equipment on systems without permission from the
responsible supervisor. Dont use a CAUTION tag if
personnel or equipment can be endangered while
performing evolutions using normal procedures. Use a
DANGER tag in these circumstances.
Attach a red DANGER tag, NAVSHIPS 9890/8
(fig. 19-6), to prohibit operation of equipment that could
jeopardize the safety of personnel or endanger
equipment, systems, or components. Never operate or
