► Alternative: Attaching warning signs:
If a machine can be locked, it must be.
However, there are situations where energy isolating devices cannot accommodate locks. In these
cases, the energy isolating devices must be tagged to warn employees that the machine is de-ener-
gized for servicing. The tag or label 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.
► Release of stored energy:
Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must be
released by appropriate means.
After switching off the machine, wait until the voltages and the compressed air have discharged, so
that work can be performed without any risk.
► Testing the lock out:
The lock can be easily tested by pressing the START button.
The following steps must be taken to restore the machine to operation.
► Check the working area. Authorized employees should remove all of their tools and reinstall all safety
features.
► Notify all affected employees.
► Before removing even one lock or tag, inform all workers in the affected area that the machine is
going to be restarted.
► Remove all locks/tags.
Every authorized employee must remove his own lock and shut it away.
► Turn the machine on. Make sure that authorized staff check the equipment in operation to ensure
that repairs were performed correctly

Testing
Service personnel may test circuits by energizing them briefly without suspending the Lock Out / Tag
Out Procedure. This may only be done 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 pre-
vent inadvertent operation of the equipment during these periods.
