OOD-CL-44 ConOps Control of Equipment and System Status

Operators note equipment deficiencies, document them in work control systems for correction, and identify them to other operators by tags, logs, status boards, or other effective method? (2.h.(5).a)

Status changes are communicated to affected operators and organizations? (2.h.(1).c)

Status changes resulting from operations or work are reported to cognizant supervisors? (2.h.(1).d)

Operating personnel are kept informed of any limiting conditions and their required actions? (2.h.(4).d)

Work control documents specify retest requirements to ensure, prior to restoration to service, proper functioning, effectiveness of the maintenance, and that no new problems were introduced? (2.h.(5).d)

Restoration of safety-related systems following maintenance includes functional testing of their capability? (2.h.(2).e)

Supervisors assure themselves of proper equipment operation before authorizing its return to service after maintenance, testing, or emergency/abnormal event? (2.h.(5).e)

Operations supervisor is responsible for maintaining proper configuration and authorizing status changes for major equipment? (2.h.(1).a)

Operators and supervisors are aware of inoperable alarms, alarms with temporary set points, multiple input alarms that do not provide indication of a subsequent condition, or other limitations? (2.h.(6).a)

Deficient alarms are documented for information to all affected personnel and entered into work control systems for correction? (2.h.(6).b)

Operators take appropriate actions to monitor conditions when alarms are unreliable? (2.h.(6).c)

Operators and supervisors are aware of alarms expected during normal operations? (2.h.(6).c)

Checklists (and/or procedures) are used to guide initial alignments and rechecks, and include equipment identification matching installed labels, required component position, data entry space for actual position and any deviations, and documentation of alignment or recheck? (2.h.(2).b)

Operating personnel periodically review Limiting Conditions of Operation for Operation and Action Statements in effect for proper implementation? (2.h.(4).d)

Administrative systems control temporary modifications; examples include electrical jumpers or lifted leads, pulled circuit cards, disabled alarms, piping jumpers or blocks, disabled relief valves, strainers or filters temporarily installed or removed, temporary shielding, blocked drains, and others. Administrative controls include; appropriate engineering review and approval of the design and safety of the modification before installation; written authorization for installation; independent verification of installation and removal; documentation of the modifications; completion of any training, procedure changes, or labeling required; and periodic audits of installed temporary modifications? (2.(h).7)
