Use TAGOUT for low voltage (below 30 volts) electrical circuit repair.
Tagout
When using tagout procedures, a written warning is attached to the switches/
circuit breakers that are placed in a SAFE or OFF position. The SAME person
shall remove the tag once the work has been completed. Tags and their attach-
ments shall be substantial enough to avoid accidental removal. The tag and
attachment shall be non-reusable, self-locking, non-releasable and attached by
hand. A nylon cable tie is recommended.
Tagout Procedure
1.
Notify all affected personnel that a tagout is required.
2.
Set the system circuit breaker to the down (off) position.
3.
Place a warning tag on the circuit breaker handle bar.
The tag must have the following information:
Date of maintenance / service action
Names of the persons performing the service procedure
Short description of the service / maintenance action
Signatures of the service supervisor and production supervisor
4.
Using a voltmeter, electrically verify that the associated circuitry
is de-energized.
Lockout
When using lockout procedures, a lock is attached to switches/circuit breakers
to keep equipment from being set in motion and endangering service person-
nel. One key is to be provided for each lock and must be kept by the person
doing the work.
Lockout Procedure
Perform Tagout procedure above, but also disconnect AC to the End
Tool and lockout per local Lockout procedures.
