: 1. PURPOSE 1.1 Provide Operations procedure usage requirements and Operations Management expectations. | |||
2.4 The term "Emergency Procedures" as used in this procedure does not include the Emergency Operating Procedures (EOPs)/Severe Accident Guidelines (SAGS) and Emergency Plan Implementing Procedures (EPIPs). Specific EOP usage isuaddressed in Procedure 5.8. | |||
2.5 AlarmrAbnormal/Emergency/System Operating Procedures/Instrument Operating Procedures may be carried out ýconcurrently with an EOP. In the event that conflicting actions are directed by procedures, the EOP actions shall take precedence. EOPs/SAMGs are Operations highest tier procedure. If an explicit operation is directed by EOPs per a 5.8 EOP Support Procedure, then transition shall be made from the Alarm/AbnormallEmergency/System Operating/Instrument Operating Procedures (including hard cards) to the 5.8 Procedure to perform or continue performing that operation. | |||
: 0. 1., | 2.6 Specific Alarm Procedureusage is addressed in Procedure 2.3.1. | ||
2.7 A required reading binder is maintained in the Control Room. The binder contains Procedure Change Requests (PCRs), that are not significant enough to require formal training prior to use, but-significant enough to ensure awareness ýand understanding of the change. Operators are required to review and initial the procedure change sheet during their first watch after the procedure is made effective. By initialing, the' Operator acknowledges they understand the described change. | |||
: 3. SYSTEM AND INSTRUMENT OPERATING PROCEDURES 3.1 System Operating Procedures (SOPs) shall be classified as Reference Use, | |||
.except for Communication Systems Operating Procedure, which will be classified as Information Use. Instrument Operating Procedures (IOPs) shall be classified as either Reference or Information Use. | |||
3.2 SOPs and IOPs contain tsections, as applicable, to fill and vent system, startup, | |||
.and secure system, layup system, operate support systems, most typical system operations, and recovering from abnormal:or emergency transients. | |||
3.3 SOP and IOP tasks have been structured to perform and complete a task with no consideration for on-going maintenance or abnormal and transient plant conditions. Examples of this are: | |||
3.3.1 Fill-and vent sections were created assuming the system was completely drained. | |||
3.3.2 Securing/shutdown sections were created assuming the complete system was in service. | |||

: 4. HARD CARDS 4.1 Hard Cards are attachments to applicable Operating Procedures, that may be used for the timely operation of equipment needed to mitigate the effects of a transient/accident. | |||
4.2 Hard Cards are created from existing procedure guidance and contain only the steps necessary to accomplish the task in the most expeditious manner. | |||
4.3 in the event of entry into an Alarm Procedure. AP, EP, or Emergency Operating Procedure, either the Hard Card or applicable section of the SOP shall be used to perform the necessary task. If an Alarm Procedure, AP, or EP directs action Without reference to an SOP, the intent is to perform the action as directedjwithout performing pre-start actions contained in the SOP. If time is notea consideration in mitigating the event, the step will direct operating equipment per the applicable SOP. | |||
4.4 Hard Cards should not be used during normal plant operations. | |||
4.5 Following completion of a task using a Hard Card, :as plant conditions permit, the associated Operating Procedure should be reviewed for applicable precautions, limitations, and subsequent steps. | |||
: 5. MITIGATING TASKS 5.1 The following tasks shall be performed from memoiy to ensure timely control of certain critical parameters during rapid plant transients. After performing task from memory, actions shall be verified with applicable procedure: | |||
5.1.1 Responding to an automatic scram or manually scramming Reactor per Procedure 2. 1.5, Attachment 1. | |||
5.1.2 Manually. controlling RPV pressure with SRVs per Procedure 2.,2.1, 5.8*,1 or.5.8.12. | |||
-5.1.3 Tripping Main Turbine per Procedure 2.2.77. | |||
5.1.4 Starting SLCInjection per Procedure 2.2.74. | |||
-5.1.5 Mahually'initiating ARI per Procedure 4.5. | |||

: 6. ABNORMAL AND EMERGENCY PROCEDURES 6.1 ABNORMAL AND EMERGENCY PROCEDURE USAGE - GENERAL 6.1.1 APs and EPs shall be classified as Continuous Use. The exception to Continuous Use is when performing Immediate OperatorActions from memory as prescribed in Step 6.7.1. | |||
6.1.2 In general, APs address less severe conditions than EPs. An exception to this are electrical casualty procedures that are grouped together as 5.3 series for improved human factoring. | |||
6.1.3 APs and EPs use a numeric-alpha numbering scheme. The alpha is a casualty or system descriptor. All APs are 2.4 series. EPs numeric series is defined below: | |||
.6.1.3.1 5.1 series typically address whole plant or large area emergencies. | |||
'6.1.3.2 5.2 series typically address -individual piping system emergencies. | |||
6.1.3.3 5.3 series typically address electrical system emergencies. | |||
6.1.3.4 5.4 series typically address fire emergencies. | |||
6.1.3.5 5.5 series typically address security emergencies. | |||
6.1.4 Procedure 0.1 requirement to verify revision is waived during an unanticipated plant transient and AP/EP response.0 6.1.5 APs and EPs have guidance for taking aggressive actions in response to plant or equipment transients. The actions are normally to shui down the reactor or affected piece.of equipment. The guidance is in place such that further degradation of plant or equipment conditions could challenge reactor or equipment safety. There are instances where the degradation of plant or equipment conditions'have reached the'action level requiring actions to be taken but are Very short-lived due to mitigating actions that have been performed. If the mitigating actions are performed land Control Room supervision determines that no equipment damage has occur!red, reactor safety has not been challenged and an automatic.trip condition has not been exceeded, then Control Room supervision can direct not performing the actions. | |||
If this occurs, the event shall be logged, Operations Department management informed, and a Notification .(use PCR Standard Text) written to evaluate the adequacy of the procedure guidance. 0 I PROCEDURE 2.0.1.2 REVISION 21 1 PAGE 4 OF 15 [ | |||
6.1.6 When an AP or EP directs action without reference to an SOP, the intent is to perform the action as directed, without performing pre-start actions contained in the SOP. If time is not a consideration in mitigating the event, the step will direct operating equipment per the applicable SOP. | |||
6.1.7 'AP and EP steps should be performed in sequence unless mitigating circumstances warrant.altering the sequence. To support priorities during event mitigation, it's acceptable to perform steps out of sequence. The procedures are typically written given the plant is at 100% power. Therefore, some actions in the procedure that are performed at power may not be applicable in other modes of operation | |||
.(e.g., tripping the main turbine and scramming the reactor). The procedures may not address all possible plant conditions and | |||
:therefore, some steps may not apply. If steps are performed out of sequence or not performed, the CRS or SM shall ensure all applicable steps are performed and procedure intent is not altered. If steps are | |||
-notperformed, justification for non-performance shall be documented/logged as discrepancies and a Notification (use PCR Standard Text) written to evaluate the adequacy of the procedure guidance. | |||
6.1.8 When an AP or EP is entered, the marked-up procedure should be retained, if necessary. for Procedure 2.0.6 review. | |||
6.2 SCRAM ACTION 6.2.1 If:scram actions are contained in an AP, EP, or Alarm Card, the first page of the procedure or alarm card will contain a "Scram Action" watermark:along the right hand margin of the page. In addition, the word scram in the :action step(s) will be capitalized and scram actions bolded. | |||
6.3 ENTRY AND EXIT CONDITIONS 6.3.1 This section is used to list Plant conditions or indications that are indicative of expected abnormal operational conditions or transients. | |||
6.4 APs and EPs shall be entered from any of following: | |||
6.4.1 When directed by another plant procedure. | |||
I PROCEDURE 2.0.1.2 1 REVISION 21 1 PAGE 5 OF 15 j | |||
6.4.2 When abnormal or emergency plant conditions are consistent with Procedure Entry Conditions: | |||
6.4.2.1 'Entry conditions are formatted as a list. Generically, if a._ny entry condition is met, the procedure should be entered unless the entry Condition specifies entry based on a logic term (e.g., "and", "or", "if", "if not', and "when"). | |||
6.5 APs and EPs may be exited by-any of following: | |||
6.5.1 'When directed by procedure. | |||
`6.5.2 When all applicable steps have been completed. | |||
.6.5.3 When conditions that required entry no longer exist and plant conditions are stable. | |||
.6.6 AUTOMATIC ACTIONS 6.6.1 AP/EP Automatic Actions identifythose-actions that will automatically occur for the transient. Only those actions directly caused by the event initiator ate listed. | |||
6.62 If a valid initiation signal exists, 'Operators shall ensure the identified automatic actions take place. Upon recognition of a failure of an automatic safety feature, Operators shall -manually perform those actions necessary to fulfill the safety function. | |||
6.7 'IMMEDIATE OPERATOR-ACTIONS 6.7.1 Immediate O.eratorActions (IOAs) shall be performed from memory and subsequently verified with the applicable procedure.0 6.7.2 IOAs are developed using following criteria: | |||
6.7.2.1 IOAs are activities 'thatstop the degradation of abnormal | |||
,or emergency conditions and mitigate their consequences by: | |||
: a. Ensuring the reactor is In a safe condition with adequate core cooling. | |||
: b. Ensuring the Reactor Coolant System pressure boundary | |||
'is intact. | |||
: c. Ensuring adequate power sources are available. | |||
PROCEDURE 2.0.1.2 REVISION 21 PAGE 6 OF 15 | |||
: d. Ensuring containment and exhaust systems (e.g., | |||
associated ventilation, SBGT, ERP) are operating properly to prevent uncontrolled release of radioactivity. | |||
6.7.2.2 IOAs must be capable of performance within areasonable time in order to stop event degradation and mitigate event consequences. The development of IOAs is based on a "reasonable time" being - 1 minute. The value of 1 minute is only for the purpose of developing IOAs and shall not be used as an Operator performance standard. | |||
6.8 SUBSEQUENT OPERATOR ACTIONS 6.8.1 This section specifies follow-up actions to be taken after the IOAs are complete. Including steps'to return the reactor or systems to a:stable condition,identify contingencies, and provide instructions to inform Operator if a Technical Specification Limitation is considered to be | |||
ýcrucial to event response or does not have an obvious association to the event. | |||
6.8.2 FLOWCHARTS 6.8.2.1 Some APs and EPs may be comprised of both a numbered step/paragraph format and a flowchart format. A flowchart, When used, will typically be an attachment to | |||
.the procedure and will contain subsequent operator actions. The flowchart will be used just as any other attachment (i.e. when directed by instructions within the procedure's main body). -A flowchart will normally be performed concurrently with the steps in the procedure body. Each flowchart is comprised of three components: | |||

- 1. PURPOSE 1.1 Provide Operations procedure usage requirements and Operations Management expectations.
1.2 These requirements/expectations are in addition to the requirements of Procedure 0.1, Introduction to CNS Operations Manual.
- 2. OPERATIONS PROCEDURE USE - GENERAL 2.1 Refer to Procedure 0. 1., Introduction to CNS Operations Manual, for CNS procedure requirements for use and adherence.
2.2 Operators shall ensure automatic safety initiations and actuations. They shall ensure automatic actions take place in response to valid initiation signals per their safety function design. Upon recognition ofa failure of automatic safety feature. Operators shall manually perform those actions necessary to fulfill the safety function.
2.3 If a completed procedure is not retained as a quality record (such as a system operating procedure), step discrepancies or non-performance shall be documented/logged as discrepancies. This requirement does not apply to "pen and ink" type discrepancies such as typos and obvious numbering errors.
PROCEDURE 2.0.1.2 REVISION 21 PAGE 1 OF 15
2.4 The term "Emergency Procedures" as used in this procedure does not include the Emergency Operating Procedures (EOPs)/Severe Accident Guidelines (SAGS) and Emergency Plan Implementing Procedures (EPIPs). Specific EOP usage isuaddressed in Procedure 5.8.
2.5 AlarmrAbnormal/Emergency/System Operating Procedures/Instrument Operating Procedures may be carried out ýconcurrently with an EOP. In the event that conflicting actions are directed by procedures, the EOP actions shall take precedence. EOPs/SAMGs are Operations highest tier procedure. If an explicit operation is directed by EOPs per a 5.8 EOP Support Procedure, then transition shall be made from the Alarm/AbnormallEmergency/System Operating/Instrument Operating Procedures (including hard cards) to the 5.8 Procedure to perform or continue performing that operation.
2.6 Specific Alarm Procedureusage is addressed in Procedure 2.3.1.
2.7 A required reading binder is maintained in the Control Room. The binder contains Procedure Change Requests (PCRs), that are not significant enough to require formal training prior to use, but-significant enough to ensure awareness ýand understanding of the change. Operators are required to review and initial the procedure change sheet during their first watch after the procedure is made effective. By initialing, the' Operator acknowledges they understand the described change.
- 3. SYSTEM AND INSTRUMENT OPERATING PROCEDURES 3.1 System Operating Procedures (SOPs) shall be classified as Reference Use,
.except for Communication Systems Operating Procedure, which will be classified as Information Use. Instrument Operating Procedures (IOPs) shall be classified as either Reference or Information Use.
3.2 SOPs and IOPs contain tsections, as applicable, to fill and vent system, startup,
.and secure system, layup system, operate support systems, most typical system operations, and recovering from abnormal:or emergency transients.
3.3 SOP and IOP tasks have been structured to perform and complete a task with no consideration for on-going maintenance or abnormal and transient plant conditions. Examples of this are:
3.3.1 Fill-and vent sections were created assuming the system was completely drained.
3.3.2 Securing/shutdown sections were created assuming the complete system was in service.
I PROCEDURE 2.0.1.2 i REVISION 21 21 1I PAGE PG2F5 2'OF 15 1I POEUE2012I R ISO
- 4. HARD CARDS 4.1 Hard Cards are attachments to applicable Operating Procedures, that may be used for the timely operation of equipment needed to mitigate the effects of a transient/accident.
4.2 Hard Cards are created from existing procedure guidance and contain only the steps necessary to accomplish the task in the most expeditious manner.
4.3 in the event of entry into an Alarm Procedure. AP, EP, or Emergency Operating Procedure, either the Hard Card or applicable section of the SOP shall be used to perform the necessary task. If an Alarm Procedure, AP, or EP directs action Without reference to an SOP, the intent is to perform the action as directedjwithout performing pre-start actions contained in the SOP. If time is notea consideration in mitigating the event, the step will direct operating equipment per the applicable SOP.
4.4 Hard Cards should not be used during normal plant operations.
4.5 Following completion of a task using a Hard Card, :as plant conditions permit, the associated Operating Procedure should be reviewed for applicable precautions, limitations, and subsequent steps.
- 5. MITIGATING TASKS 5.1 The following tasks shall be performed from memoiy to ensure timely control of certain critical parameters during rapid plant transients. After performing task from memory, actions shall be verified with applicable procedure:
5.1.1 Responding to an automatic scram or manually scramming Reactor per Procedure 2. 1.5, Attachment 1.
5.1.2 Manually. controlling RPV pressure with SRVs per Procedure 2.,2.1, 5.8*,1 or.5.8.12.
-5.1.3 Tripping Main Turbine per Procedure 2.2.77.
5.1.4 Starting SLCInjection per Procedure 2.2.74.
-5.1.5 Mahually'initiating ARI per Procedure 4.5.
I PROCEDURE 2.0.1.2 I REVISION,21 I PAGE 3 OF 15 1I RCDR .. 12RVSO 1 I AE3F5
- 6. ABNORMAL AND EMERGENCY PROCEDURES 6.1 ABNORMAL AND EMERGENCY PROCEDURE USAGE - GENERAL 6.1.1 APs and EPs shall be classified as Continuous Use. The exception to Continuous Use is when performing Immediate OperatorActions from memory as prescribed in Step 6.7.1.
6.1.2 In general, APs address less severe conditions than EPs. An exception to this are electrical casualty procedures that are grouped together as 5.3 series for improved human factoring.
6.1.3 APs and EPs use a numeric-alpha numbering scheme. The alpha is a casualty or system descriptor. All APs are 2.4 series. EPs numeric series is defined below:
.6.1.3.1 5.1 series typically address whole plant or large area emergencies.
'6.1.3.2 5.2 series typically address -individual piping system emergencies.
6.1.3.3 5.3 series typically address electrical system emergencies.
6.1.3.4 5.4 series typically address fire emergencies.
6.1.3.5 5.5 series typically address security emergencies.
6.1.4 Procedure 0.1 requirement to verify revision is waived during an unanticipated plant transient and AP/EP response.0 6.1.5 APs and EPs have guidance for taking aggressive actions in response to plant or equipment transients. The actions are normally to shui down the reactor or affected piece.of equipment. The guidance is in place such that further degradation of plant or equipment conditions could challenge reactor or equipment safety. There are instances where the degradation of plant or equipment conditions'have reached the'action level requiring actions to be taken but are Very short-lived due to mitigating actions that have been performed. If the mitigating actions are performed land Control Room supervision determines that no equipment damage has occur!red, reactor safety has not been challenged and an automatic.trip condition has not been exceeded, then Control Room supervision can direct not performing the actions.
If this occurs, the event shall be logged, Operations Department management informed, and a Notification .(use PCR Standard Text) written to evaluate the adequacy of the procedure guidance. 0 I PROCEDURE 2.0.1.2 REVISION 21 1 PAGE 4 OF 15 [
6.1.6 When an AP or EP directs action without reference to an SOP, the intent is to perform the action as directed, without performing pre-start actions contained in the SOP. If time is not a consideration in mitigating the event, the step will direct operating equipment per the applicable SOP.
6.1.7 'AP and EP steps should be performed in sequence unless mitigating circumstances warrant.altering the sequence. To support priorities during event mitigation, it's acceptable to perform steps out of sequence. The procedures are typically written given the plant is at 100% power. Therefore, some actions in the procedure that are performed at power may not be applicable in other modes of operation
.(e.g., tripping the main turbine and scramming the reactor). The procedures may not address all possible plant conditions and
- therefore, some steps may not apply. If steps are performed out of sequence or not performed, the CRS or SM shall ensure all applicable steps are performed and procedure intent is not altered. If steps are
-notperformed, justification for non-performance shall be documented/logged as discrepancies and a Notification (use PCR Standard Text) written to evaluate the adequacy of the procedure guidance.
6.1.8 When an AP or EP is entered, the marked-up procedure should be retained, if necessary. for Procedure 2.0.6 review.
6.2 SCRAM ACTION 6.2.1 If:scram actions are contained in an AP, EP, or Alarm Card, the first page of the procedure or alarm card will contain a "Scram Action" watermark:along the right hand margin of the page. In addition, the word scram in the :action step(s) will be capitalized and scram actions bolded.
6.3 ENTRY AND EXIT CONDITIONS 6.3.1 This section is used to list Plant conditions or indications that are indicative of expected abnormal operational conditions or transients.
6.4 APs and EPs shall be entered from any of following:
6.4.1 When directed by another plant procedure.
I PROCEDURE 2.0.1.2 1 REVISION 21 1 PAGE 5 OF 15 j
6.4.2 When abnormal or emergency plant conditions are consistent with Procedure Entry Conditions:
6.4.2.1 'Entry conditions are formatted as a list. Generically, if a._ny entry condition is met, the procedure should be entered unless the entry Condition specifies entry based on a logic term (e.g., "and", "or", "if", "if not', and "when").
6.5 APs and EPs may be exited by-any of following:
6.5.1 'When directed by procedure.
`6.5.2 When all applicable steps have been completed.
.6.5.3 When conditions that required entry no longer exist and plant conditions are stable.
.6.6 AUTOMATIC ACTIONS 6.6.1 AP/EP Automatic Actions identifythose-actions that will automatically occur for the transient. Only those actions directly caused by the event initiator ate listed.
6.62 If a valid initiation signal exists, 'Operators shall ensure the identified automatic actions take place. Upon recognition of a failure of an automatic safety feature, Operators shall -manually perform those actions necessary to fulfill the safety function.
6.7 'IMMEDIATE OPERATOR-ACTIONS 6.7.1 Immediate O.eratorActions (IOAs) shall be performed from memory and subsequently verified with the applicable procedure.0 6.7.2 IOAs are developed using following criteria:
6.7.2.1 IOAs are activities 'thatstop the degradation of abnormal
,or emergency conditions and mitigate their consequences by:
- a. Ensuring the reactor is In a safe condition with adequate core cooling.
- b. Ensuring the Reactor Coolant System pressure boundary
'is intact.
- c. Ensuring adequate power sources are available.
PROCEDURE 2.0.1.2 REVISION 21 PAGE 6 OF 15
- d. Ensuring containment and exhaust systems (e.g.,
associated ventilation, SBGT, ERP) are operating properly to prevent uncontrolled release of radioactivity.
6.7.2.2 IOAs must be capable of performance within areasonable time in order to stop event degradation and mitigate event consequences. The development of IOAs is based on a "reasonable time" being - 1 minute. The value of 1 minute is only for the purpose of developing IOAs and shall not be used as an Operator performance standard.
6.8 SUBSEQUENT OPERATOR ACTIONS 6.8.1 This section specifies follow-up actions to be taken after the IOAs are complete. Including steps'to return the reactor or systems to a:stable condition,identify contingencies, and provide instructions to inform Operator if a Technical Specification Limitation is considered to be
ýcrucial to event response or does not have an obvious association to the event.
6.8.2 FLOWCHARTS 6.8.2.1 Some APs and EPs may be comprised of both a numbered step/paragraph format and a flowchart format. A flowchart, When used, will typically be an attachment to
.the procedure and will contain subsequent operator actions. The flowchart will be used just as any other attachment (i.e. when directed by instructions within the procedure's main body). -A flowchart will normally be performed concurrently with the steps in the procedure body. Each flowchart is comprised of three components:
- a. Instruction blocks (squares :or rectangles) that contain Action steps brinformhation in support of action performance.
- b. Decision blocks (diamonds) that normally contain Yes/No questions.
- c. Flow lines :(lines with arrows) that direct the sequence of actions and decisions.
I PROCEDURE 2.0.1.2 1 REVISION 21 1 PAGE 7 OF 15 J
6.9 DISCUSSION 6.9.1 This section states the objective of the procedure. Since the Abnormal and Emergency Procedures are event based procedures, the section identifies the major parameters/systems being controlled by the procedure and when applicable, includes the reasoning behind steps in the procedure if those steps must be performed for a specific reason or commitment, and it is not obvious for the reasoning for those steps.
This section also includes relevant probable annunciators, indications, and causes associated with the event.
6.10 REFERENCES 6.10.1 This-section contains any procedures referenced by the procedure and other applicable 'references such as Technical Specification sections; drawings, etc.
- 7. PLANT PROCEDURE AUDIT 7.1 An auditshall be performed quarterly on plant procedures located in the Control Room and on those procedures the Operations Department is responsible for at designated locations outside of the Control Room. These audits shall ensure these procedures are located properly and are of the latest procedural ;revision.
7.2 The Operations Clerk is responsible for ensuring an audit is conducted quarterly on procedures located in the Control Room. This audit shall entail using a list of the procedures located in the Control Room with the latest revision number indicated arid -a verification that the procedures in place in the Control Room are of the latest revision. Any procedures identified as not of the latest revision shall be removed and the latest revision inserted in place.
The Control Room procedure list and audit records shall be maintained by the Operations Supervisor..
7.3 TheRadwaste Operations Supervisor is responsible for ensuring an audit is conducted quarterly on procedures the Operations Department is responsible for at designated locations outside of the Control Room. This audit shall entail using a list of those procedures located outside of the Control Room'with the latest revision number indicated and a verification that the procedures in place
'outside of.the Control Room are of the latest revision. Any procedures identified as not of the latest revision shall be removed and the latest revision inserted in place. The 'list of procedures outside of the Control Room and audit records shall be maintained by the Radwaste :Operations Supervisor.
I PROCEDURE 2.0.1.2 REVISION 21 1 PAGE 8 OF 15 [
- 8. SAFETY GUIDE 33/ANSIN18.7 8:1 This-Section identifies the'Safety Guide 33/ANSI N18.7 Emergency, Abnormal, and System Operating Procedure recommendations, not implemented by the CNS Operations Department. Each applicable document and section -number is first:identified, followed by the CNS Operations position.
8.2 ANSI N18.7, Section 5.3.8.1 (4) - The notification of plant personnel of the nature of an emergency is not considered to be an IOA. It typically takes some time to validate and establish an accurate picture of plant status. Notifying personnel "Immediately" could result in erroneous information and an improper or unsafe response by plant personnel. In addition, personnel notification is controlled by the Operation communication standard and does not meet the IOA~criteria.
8.3 ANSI N18.7, Section,5.3.8.1 (4) -The verification of Automatic Actions is not considered to be an IOA. The verification of Automatic Actions is considered to be a universal -orstandard Operator response that does not require a specific procedure step to trigger performance. CNS Abnormal and Emergency Procedures do providea list of applicable Automatic Actions, that are used by the Operator to verify the correct system/component response.
- 8.4 ANSI N1837, Section 5.3.2.8 - Operations procedures do not usually contain "check-off' lists as suggested in the standard. Operations used to 'use check-off lists, but-now uses Initial blocks or check-off boxes within the body to ensure place keeping. Unto "themselves checklists are good tools, but are very brief in terms of-guidance. For accurate task completion, both the checklist and body of the procedure have to be used in conjunction with each other. Using two documents in parallel is poor human-factoring.
- 9. RECORDS 9.1 No quality records are generated by this procedure.
