EQUIPMENT TAG-OUT PROCEDURES
Post DANGER tags, CAUTION tags, and
instrument OUT-OF-COMMISSION tags or OUT-OF
CALIBRATION labels following authorized
procedures. Those tags and labels will help ensure the
safety of personnel and prevent improper operation of
equipment. Do not remove or break posted safety tags
without proper authorization. Chapter 6 of Standard
Organization and Regulations of the U.S. Navy,
OPNAVINST 3120.32, contains basic guidelines and
standardized procedures for tag-out procedures. Basic
Military Requirements, NAVEDTRA 14277, discusses
the tag-out procedures in detail. In this topic the
purpose of the tag-out bill, tag-out logs, record sheets,
and audits will be presented.
Purpose
An equipment tag-out bill has three purposes. The
first purpose is to provide a procedure for personnel to
use to prevent the improper operation of a component,
piece of equipment, a system, or portion of a system that
is isolated or in an abnormal condition. The second
purpose is to provide a procedure for personnel to use in
operating an instrument that is unreliable or not in a
normal operating condition. This procedure is similar to
the tag-out procedure except that it requires the use of
labels instead of tags to indicate instrument status. The
last purpose is to provide separate procedures for
personnel to use when accomplishing certain planned
maintenance system (PMS) maintenance actions. These
procedures apply only to non-nuclear surface ships and
craft and non-nuclear, non-propulsion areas of nuclear
surface ships. PMS tag-out procedures are not
authorized aboard submarines, submarine tenders,
submarine rescue vessels, in propulsion areas of nuclear
surface ships, or within submarine support facilities.
All U.S. Navy ships and repair activities must use
standardized tag-out procedures.
Tag-out Logs
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 that 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
concerning 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
water systems.
The tag-out log is a record of authorization of each
effective tag out action. It contains the following
documents:
A copy of the main instruction and any other
amplifying directives for administering the system.
(These documents are kept in the front of the log.)
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 also are used in
audits of the log 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.)
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.
RECORD SHEETS.Some ships going through
an overhaul have used between 2,000 and 3,000
DANGER/CAUTION tags. Ships personnel use the
record sheets to keep track of all these tags. The front of
the record sheet contains the name of the system or
component, serial number of the tag out, date/time of tag
out issue, and reason for the tag out. The sheet also
contains a place for documentation (blueprints, rip outs,
etc.) and authorizing signatures. On the back of the
