A tag-out procedure is necessary because of the
complexity of modem ships and the cost, delays, and
hazards to personnel that can result from the improper
operation of equipment. Learn and use the following
1. Enforce the tag-out procedure at all times. You
must do this during normal operations as well as during
construction, testing, repair, or maintenance.
2. Do not use tags or labels as a substitute for other
safety measures. Examples are chaining or locking
valves, removing fuses, or racking out circuit breakers.
However, you must attach tags to the fuse panel, the
racked-out circuit breaker cabinet, or a locked valve to
show a need for action. You do not need to use tags
where a device will be locked during normal operations.
3. Use tags to show the presence of, and the
requirement for, freeze seals, blank flanges, or similar
safety devices. When equipment or components are
placed out of commission, use the tag-out procedures to
control the status of the affected equipment. Examples
are disconnecting electrical leads, providing jumpers, or
pulling fuses for testing or maintenance.
4. Never use tag-outs to identify valves, to mark
leaks, or for any purpose not specified in the tag-out
5. Do not laminate tags or labels for reuse. The
reuse of tags or labels is not allowed.
