Entering/Exiting Technical Safety Requirements

DOE-STD-1035-93

4.2.3

Entering/Exiting Technical Safety Requirements

Any time facility conditions justify restricted operations in accordance with

technical safety requirements, an entry to that effect should be made in the log.

Another log entry, recording the elapsed time under technical safety requirement

restriction, should be made when operations return to normal. Logging these

events serves as an aid to the operator on shift, emphasizing the importance of the

technical safety requirements, as well as documenting compliance with regulatory

and safety limitations.

4.2.4

Out-of-Specification Readings

During operator rounds, the log can serve as a supplement to the round sheet by

providing space for narrative comments on the condition and status of the

equipment. Any out-of-specification reading or indication should be explained in

the log. The log may also be used to record both objective and subjective

observations regarding the condition of the equipment. Subjective observations,

such as abnormal noise, vibration, odor, humidity, dust, temperature, etc., often

enable qualified operators to identify problem precursors before process

parameters exceed their permissible limits.

Log entries documenting abnormal observations or readings should include a

description of the abnormal condition, the corrective actions and notifications

made by the operator, and the cause of the condition, if it can be determined.

Whether or not the abnormal condition can be corrected by the operator, the log

entry will alert other operators to the potential problem. The log entry also

preserves the operator's first-hand observations and reactions in the event a more

comprehensive investigation is required. The sample log in Appendix A illustrates

entries (Notes 5 and 8) for problems or out of specification conditions discovered

by the operator.

4.2.5

Occurrence of Reportable Events

The occurrence of any event that is reportable outside the immediate operating

group or shift should be recorded in the log. Log entries for reportable events

should identify the person(s) notified, the time(s) of notification, and the actions

taken by the operator to correct the event or condition. Events and conditions

that are reportable to DOE are identified in DOE Order 232.1A, Occurrence
