Preparation
Employees authorized to perform lockout shall ensure that the appropriate energy isolating device
(circuit breaker, fuse, disconnect, etc.) is identified for the lift being locked out Other such devices for
other equipment may be located in close proximity of the appropriate energy isolating device. If the
identity of the device is in question, see the shop supervisor for resolution. Assure that proper
authorization is received prior to performing the lockout procedure.
Sequence of Lockout Procedure
Notify all affected employees that a lockout is being performed and the reason for it.
Unload the subject lift. Shut it down and assure the disconnect switch is "OFF" if one is provided on
the lift.
The authorized lockout person operates the main energy isolation device removing power to the
subject lift.
If this is a lockable device, the authorized lockout person places the assigned padlock on the device
to prevent its unintentional reactivation. An appropriate tag is applied stating the person's name, at
least 3"x 6" in size, an easily noticeably color, and states do not operate device or remove tag.
If this device is a non-lockable circuit breaker or fuse, replace with a "dummy" device and tag it
appropriately as mentioned
above.
Attempt to operate lift to assure the lockout is working. Be sure to return any switches to the "OFF"
position.
The equipment is now locked out and ready for the required maintenance or service.

At this point, the authorized person can remove the lock (or dummy circuit breaker or fuse) & tag and
activate the energy isolating device so that the lift may again be placed into operation.
