PROCEDURE NUMBER A OVE DATE 06/09/82 VOLUME NAME ACMINIST SECTION 1.3 CONDUCT OF OPERAT TITLE

+1.3.8 E UIPMENT CLEARAN A T 1.3.8.1 ~Pue oee This procedure provides direction for the proper method of requesting, issuing, lifting and releasing Clearance Orders (CO). The "Danger" and "Caution" tags are placed on plant equipment to provide for safety of personnel and equipment protection.

It must be understood that a Danger Tag Clearance Order and associated "Danger" tags represent a lifesaving procedure and SMALL BE INVIOLATE.

Violation of one of these tags or the Clearance Order procedure by anyone SHALL be sufficient cause for IMMEDIATE'ISCIPLINARYACTION.

1.3. 8e 2 Discussion A. Definitions "Dan er" Ta s are those red tags and stickers-represented by A ac ments I and II respectively and are used when personnel safety is of primary concern,

~t' Attachments III and tt yll tg IV respectively d tik and are used tdt to provide temporary ins'tructions or limited-operation of equipment.

"Clearance Order Release" is the process of closing out a Clearance Order and thereby placing it into the "closed" section of the Clearance Order Log.

"Closed" Clearance Order is a Clearance Order that has been released, removed and is no longer in effect.

"Multi le" Clearance Order is a Clearance Order that provides work protect on for more than one purpose or job while utilizing one Clearance Order and its associated tags.

t "Authorized Individual"8 shall be any permanent Supply System employee or any n v ua who s on the authorization list. The authorization list shall be maintained in the form of the Clearance Order Log and approved by -the Operations Manager.

"Redundant Verification" is that requirement directing a second ndividual to make an independent verification of correct equipment status for safety related equipment. This can be accomplished from the.

main control room when adequate status indication is available or by local status verification when necessary.

B. All Clearance Order Tags (RDanger" and "Caution" ) are placed, accounted for and removed only in conjunction with a properly authorized Clearance Order.

1. The "Danger" tag is placed as an assurance that the syste, or equipment will NOT be changed from the status tagged except as provided by this procedure.

20 The "Caution" tag is placed as an assurance that the system or equipment will be operated only as provided by the instruction or limitations described on the tag.

Because the two Clearance Order tags have different functions, the "Danger" tag shall have precedence and priority over a "Caution" tag.

4. This -procedure allows for multiple use of- a single clearance.

"multiple" Clearance Orders should be used only when the 'hese boundaries are mutual, common and uncluttered.

If any doubt exists, it is better to issue a redundant Clearance Order and associated tags.

5. . This procedure provides for temporarily lifting of "Danger" tags, when work is complete, for testing of component just prior to Clearance Order Release.

1.3.8.3 Procedure The Clearance Order Log will be maintained in the Control Room. It consists of two loose leaf type binders, one for the "Danger" Clearance Orders and one for the "Caution" Clearance Orders. Each binder will be divided into two sections: an active section containing the Clearance Orders in effect and a closed section containing the Clearance Orders that have been closed.

On a monthly basis, a person designated by the Operations Manager will review both logs and take appropriate action to clear any unnecessary Clearance Orders.

t Closed Clearance Or ers will remain in the closed section for a minimum days from date of-closure. All closed Clearance Orders beyond the 30 days that are no longer needed shall be forwarded to the Plant Records of'0 Center for disposition.

A. ~Authorit The Shift Manager is responsible for administration of the the Clearance Order Program. This responsibility cannot be delegated.

Signature authority for the functioning of the Clearance Order Program may be o legated. For ur oses of this rocedure rocessin the term Shift Mana er shall nclude h s s nature esi nate un ess s ec f ed ot erw se. The authorized in iv dual accepting the Clearance Or er or continuing work'nder a Clearance Order issued to a work document is responsible for verifying a safe working condition..

B. Clearance Order Issuin Clearance Orders may be issued in one of three methods. They may be issued to an authorized individual by name, person in charge of work by a work document, or Duty Shift Manager by title. In addition, during system lineup and testing, clearance orders can be issued to a work document number or to any authorized test engineer.

In the case of the latter two, the person-currently in charge of the work or the on-duty Shift Manager accepts or releases the Clearance Order. Also, during system lineup and testing, test directors may accept or release clearance orders issued t'o their assigned test enginebrs.

The request for a Clearance Order is made through the Control Room, i.e., Plant Operations Department. An assigned operator will then determine the requirements to provide a safe work condition and initiate the appropriate Clearance Order Form, Attachment V or VI as directed below. These forms contain an original (white), a yellow and a pink copy. The pink copy is issued with the tags for use in processing the Clearance Order. The yellow copy is retained with the original in the active section of the log for use at the time of Clearance Order release.

l. Upon receipt of a Clearance Order request the assigned operator will:

a., Enter the "Equipment/System" description and the "Purpose" on the Clearance Order,

b. Determine the required tag locations and the desired component status and record this information in the "Tag Location" and "Tags Hung" sections of the Clearance Order. If more than ten tags are required, an addendum will be issued (Attachment VII). The use of an addendum will be PROCE~Rg NUI IBER REVISION NUMBER Iod ~ 0 P.S.P-Y of 16 V/P 598

C~ Number. each tag with the Clearance Order number and the appropriate tag number shown in the "Tag Location" section of the Clearance Order.

d. Denote on each tag the equipment name and/or piece number and required component status.
e. Enter the work document number, authorized individual name or Shift Manager on the Clearance Order.
f. Present the tags and Clearance Order to the duty Shift Manager.
2. The Shift Manager. will assure that the'learance Order provides the safe conditions necessary for the protection of. personnel and will:
a. Sign the "Authorized By" in the "clearance issue" section and enter the date and time.

b. Assign an operator to hang the tags and place the equipment in the specified status.

The assigned operator will thoroughly review the operational tasks required and will then:

a. Position valves, breakers, switches or other devices in the status specified.
b. Hang the tags and initial the Clearance Order original adjacent to the designated position for each component.
c. Inform the Shift Manager that the clearance has been placed.
4. The Supply System representative responsible shall thoroughly understand the requirement necessary to accomplish the work and the limits of the clearance and shall:

a~ Verify that the Clearance Order provides a safe working condition and so signify by signature in the "Accepted By" section of the Clearance Order. This signature is not intended to prevent an assigned craftsman from further verifying safe working conditions.

b. Notify the control room operator of start of work.

C. Clearance Order Release Tags removal and Clearance Order release will be approved by the Shift Manager. It. will be. approved when the authorizated individual to whom it is issued, the person in charge of the work under a work document, or "he duty Shift Manager as the case may be,has signed the "Released By" section'of the Clearance Order original. This signature indicates that the work is complete or cancelled and that tag removal will not result in an unsafe situation.

l. 'Upon assuring that the clearance order has been properly released and that no safety hazards exists, the Shift Manager will authorize release of the Clearance Order by:

a~ Indicating if "Redundant Verification" is required is safety related.

when the component J

b. Signing the "Authorized By" section of the Clearance Order and entering the "Date" and "Time" in the column provided.
c. Having the tags removed and the equipment returned to service. A column is provided on the Clearance Order to allow the Shift Manager to specify the component status following tag removal. This column ("Return Status" ) should be used when the Shift Manager determines that a specific component status is needed.
2. An assigned operator(s) will:
a. Remove the tags.
b. Return the equipment to service as required.
c. Initial the space provided adjacent to "Return Status" column.
d. When all tags are removed and accounted for, sign the "Tag(s)

Accounted For By" section of the Clearance Order original and destroy the tags.

e. When redundant verification is necessary, a second individual will verify the return status requirement and initial in the space provided in the "Dual" initial column.

D. Multi le Use of Clearance Order Where more than one authorized work task is preplanned for a scheduled outage of a major piece of equipment or system, more than one clearance may be granted under a Clearance Order. The implementation of this provision requires the same procedures as described above except that the requests will normally be made in advance.

PROCEOURE NUMBER REVISION NUMBER PAGE NUMBER 1.3.8 1.3.8-5 of 16 WP.598

. 0 Tags cannot be removed or equipment returned to service until all clearances have been released by the Shift Manager signing "Clearance Order Release Authorized'By" section.

Clearance for additional work (see Section "E") may be granted under an existing Clearance Order at the discretion of the Shift Manager. When granting an additional work clearance under an existing Clearance Order, the purpose and the equipment description will be recorded in the "Remarks" section and the appropriate information and signatures recorded in the "Remarks" section and the appropriate information and signatures recorded'in the "Clearance Issue" 'and "Clearance Release" sections.

E. Clearance Order Chan e A change of clearance status will be utilized to allow: 1)'addicional work under an existing Clearance Order with additions to the "Tag Location" section, 2) removal of tags to allow return to ser.ice of a component or portion of a system, and 3) operation which the Shift Manager deems warrant a Clearance Order change.

Due to the complicated nature of the approvals and reviews involved in ensuring safe. work conditions, under no condition will a Clearan'ce Order be changed that already has more than one work document associated with it.

A change of clearance status is made only after the Shift Manager has reviewed the proposed change and determine'd that the change does not compromise the initial clearance order. If the proposed change represents a complicated shuffling of tags and/or an unwarranted opportunity for errors during the tagging process, the Shift Manager should issue a new clearance and a new'et of tags. In addition.to the Shi'ft Manager's approval, the details for the proposed change shall be reviewed with an approved by the authorized individual responsible for associated Clearance Order. His initials adjacent to the changes will signify his approval.

A Clearance Order change shall be implemented as follows:

1. The addition and/or deletion of tags will be recorded in the "Tag Location" section and the changes initialed by the Shift Manager.
2. A description of the change and the reason for it "in the "Remarks" section and the entry initialed by the Shift will be recorded Manager and the authorized individual responsible for the associated Clearance Order.

If the change allows additional work under the existing Clearance Order, the appropriate blank in the "Clearance Issue" and "Clearance Release" section will also be completed as per Section D above.

I F. Tem orar LiftWi of Ta s When there would be a great advantage to performing.a brief checkout or test without'eleasing a Clearance Order, the Shift Manager and the authorized individual holding the Clearance Order can agree to temporarily lift some of the tags. Only checkout or test that should take a short time (less than one hour) are allowed. They may=not run through a shift change. If the Clearance Order is a multiple Clearance-Order tern orar liftin of the ta s is not ermitted. The temporary lift ng may be terminated at any time by either of the agreeing parties.

'he sequence is as follows:

l. Agreement between the Shift Manager and the authorized individual holding the Clearance Order as to need and limits of the test and tag lifting.
2. An operator will'e assigned to temporarily lift the specified tags and perform"the test as directed. The assigned operator must stay in the area of the equipment or where the tags were lifted while the tags are removed. He is to have no other duties or interference.
3. After the test, the assigned operator will insure the components are returned to their tagged position and the tags replaced.
