Information to be Recorded

DOE-STD-1035-93

4.2 Information to be Recorded

Each facility should provide written guidance defining the type and scope of information to

be included in the logs. Log entries should be concise, yet contain sufficient information

to allow accurate reconstruction of events. During emergencies and abnormal or

unexpected events, logkeeping should not take precedence over controlling the facility;

however, it is important that as much significant information as possible be included in the

log. Entry of information into the log should not be regarded as a substitute for reporting

to supervisors or other required reporting.

Log entries need not duplicate information recorded in other permanent records, such as

round sheets or logs for other shift positions. However, any information that is of

operational interest should be recorded in at least one facility log. If the operator is in

doubt as to whether the information must be recorded, it is usually better to record. The

following subsections identify categories of information that should be recorded in logs.

4.2.1

Changes in Facility or Equipment Status

Any change in the status or operating mode of equipment, systems, and processes

(e.g., startup, shutdown, depressurizing, preheating, etc.) should be recorded in

the log. The log should identify the specific procedure, or portion of a procedure,

that is used. The initiation and completion of required surveillance or operational

testing, and verification of status for safety-related equipment should also be

recorded.

4.2.2

Abnormal Configurations

Occasionally a facility or system must be operated in an abnormal configuration

to support maintenance or testing, or to respond to emergency conditions.

Examples of abnormal configurations include: electrical or hose jumpers installed

to bypass certain components or functions, blocked or locked-out safety channels

or instrumentation, intentionally plugged drains, pinned or blocked check valves

or other flow-control devices, or power supplied from an alternate source. When

equipment is placed in an abnormal configuration, the reason (e.g., maintenance,

testing, inoperability of normal equipment), authority for doing so (e.g.,

procedure, supervisor instruction), expected duration, and any special precautions

should be recorded in the log.
