– Alternatively: tag out procedure
If a machine can be locked out, it must be. However, there are situations where energy iso-
lating devices cannot accommodate locks. In these cases, the energy isolating devices must
be tagged to warn employees that the machine is de-energized for servicing. The tag must
be securely fastened, it must be placed in a position visible to all and it may only be removed
by the person who attached it. 2
(A) Turn the operating lever counterclockwise.
(B) Use the screwdriver to push the locking lug out of the operating lever.
(C) Secure the operating lever with a padlock.

Release stored energy
Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must
be released by appropriate means. 2
After switching off the machine, wait the specified discharge or pressure unloading time
(see sections 2.8
, page 78, and 2.9, page 82), before the machine can be operated again
without risk.
Verify the lock out.
Testing the lock out can be done simply by pressing the start button.
The following steps must be taken to restore the machine to operation.
Check the area. Authorized employees should remove all of their tools and reinstall all
guards.
Notify all affected employees.
Before removing even one lock or tag, inform all workers in the area that the machine is going
to be restarted.
Remove locks/tags
Each authorized employee must remove his or her own lock. Each authorized employee will
have his or her own lock.
Turn the machine on. Authorized workers should observe the equipment in operation to in-
sure repairs were done correctly.
2.11.3 Testing
Service personnel may test the circuits by activating them briefly without canceling the locking
method. This may be done only when no other work is being performed by any other person on
the equipment being tested.
It is extremely important that all remote start switches be tagged with the Do Not Operate tag to
prevent inadvertent operation of the equipment during these periods.
2.11.4 Responsibility and obligations
– It shall be the responsibility of the maintenance and service personnel to make sure this pro-
cedure is adhered to.
– It shall be the responsibility of the maintenance and service personnel’s immediate supervisor
to instruct his personnel on this procedure.
– It shall be the responsibility of the Safety Officer with assistance from the Safety Committee,
Health Service Department, and the various managers and Vice-presidents to administer the
Lock Out / Tag Out Procedure.
