> Locking and Tagging from Operating Procedures for High Voltage
> (601-115,000 Volts AC) Electrical Work, Section 7.1.7.

When HV electricians are working on or near circuits or equipment under
circumstances in which the unexpected movement of parts or the
energizing of electrical conductors could cause injury to personnel or
damage to equipment, the following precautions for isolating and
disconnecting all energy sources and locking and tagging shall be taken:

A. Lockout/Tagout Sequence

> 1\. Conduct a survey to locate and identify all isolating devices to
> be certain which switch(s), or other energy isolating devices apply to
> the equipment or circuit to be locked/tagged. If questions arise
> during the survey on the isolation of a device, contact the management
> in 10842 or 10821 for assistance.
>
> 2\. All circuits and hardwired equipment shall be provided with a
> positive means of locking out all power or treated as being energized.
> For older installations, see Section 7.1.7A3.
>
> 3\. Any device that will not accept a lock can be tagged out by
> utilizing a tag and isolating the conductors from the source.
> Isolation of the conductors shall be done by one of the following
> methods: disconnecting, taping, and tagging the conductors; removing
> the fuses; or racking out and tagging the circuit breaker. No lock
> will be required but this device shall be reported to supervision and
> steps taken to have a lockable disconnecting means installed if
> possible. Devices that are not designed to accept a lock, located in
> an inaccessible location or made inaccessible (i.e., cutouts on a
> pole), and it is not feasible to physically remove the conductors to
> isolate the circuit, shall be tagged only.
>
> 4\. Notify users affected by the lockout of a circuit that the system
> will be out of service until the work is completed.
>
> 5\. Shut down energized machines and equipment using normal shutdown
> procedures prior to locking out and tagging out a circuit.
>
> 6\. Disconnect all electrical power at its nearest disconnect point.
>
> 7\. Test to make sure that the circuit is de-energized.
>
> 8\. Securely lock the disconnecting means so that only the person(s)
> who is exposed may allow the power to be reapplied by removing his
> respective lock. Multiple lockout devices shall be used when it is
> necessary for more than one employee to work on the system (machine or
> equipment).
>
> a\. Multiple Lockout Devices - Each affected employee shall then
> install his own lock on the multiple lockout device. Each employee
> shall have his own lock that is keyed differently from all other
> employees locks. Only one key is allowed for each lock. Each lock
> shall have an approved band with the employees last name printed on
> this band.
>
> b\. Lock Boxes -- A designated person shall lock the disconnecting
> means. The lock shall have an approved band with the Lock Box number
> and telephone number of the designated person (as called out in the
> switching procedure) printed on it. The only key to this lock is
> placed in the Lock Box and each affected employee shall then install
> his own lock in the Lock Box. Each employee shall have his own lock
> that is keyed differently from all other employee locks. Only one key
> is allowed for each lock. Each lock shall have an approved band with
> the employees last name printed on this band.
>
> c\. Note: Locking out a control circuit, which in turn, shuts off
> power is not acceptable or approved. Locking shall occur at all
> locations where power enters a machine or piece of equipment
> (including the power to the controls) such as the main electrical
> disconnect. The controls of the equipment being locked out/tagged out
> shall be operated to confirm that the equipment is de-energized.
>
> 9\. Each employee shall securely attach a tag to their own lock. The
> information on the tag shall include the employee\'s last name,
> organization number, date of installation, and the reason for the
> lockout or tagout. The tag shall be used to supplement the lock, not
> to take the place of a lock. Refer to the exception in 7.1.7A3.
>
> 10\. Relieve, restrain, or otherwise render safe all potentially
> hazardous stored energy on the equipment that is being worked on.
>
> 11\. If needed, implement additional safety measures such as removal
> of isolating circuit elements, opening of extra disconnecting devices,
> etc. to minimize inadvertent energization.
>
> 12\. Retest to ensure that the equipment is still de-energized. When
> applicable, ensure that all personnel are clear and operate the
> control circuit to verify that the equipment will not operate. After
> checking the controls, be sure to return the control to the neutral or
> the off position.

B. Sequence for Restoring the Equipment to Energized State

> 1\. Remove all tools, parts, and debris from the area that will be
> re-energized.
>
> 2\. Notify any affected employees that the power is about to be
> restored.
>
> 3\. If work cannot be completed in one work shift, do not remove the
> lock until your relief is present and is ready to install their own
> lock.
>
> 4\. Remove lock and tag. Only the person who installed the lock and
> tag may remove them. Refer to the exception listed in Section 7.1.7C.
>
> 5\. Operate the disconnect device to restore power.

C. Emergency Removal of a Lock and Tag

> 1\. If a lock and tag has been forgotten by an employee who has gone
> home or is otherwise unavailable, the employee\'s supervisor shall be
> notified.
>
> 2\. The supervisor shall make all reasonable efforts to contact the
> employee at their home to find out the status of work and why the
> device has not been removed.
>
> 3\. The supervisor shall make a thorough inspection of the work
> location. During the inspection the supervisor shall make sure that
> the employee is not at the facility and that all other employees are
> clear of the equipment to be energized. The supervisor must perform
> steps 1 and 2 in Section B prior to removing a lockout/tagout that was
> installed by another employee.
>
> 4\. If it is determined that the removal of the lockout tagout device
> and the energizing of the equipment will not endanger either employee
> or equipment, then the supervisor may order the removal of the lock
> and tag and energize the circuit.
>
> NOTE: The supervisor removing the LOTO device assumes full
> responsibility for his actions.
>
> 5\. The supervisor shall notify the employee prior to his starting
> work the next work day that the lock and tag have been removed and the
> system is energized.
>
> 6\. Document the lock/tag removal, reason for the removal, and the
> discussion with the employee who left the devices on.

D. Isolation or Switching of System Where No Hands On Work is Involved

> 1\. Management in 10842 may lock and tag out a system, but they must
> follow the steps listed in Sections 7.1.7 A, B and C.
