The situation

What has happened

At 9:15 pm on 8 September the SCADA system raised a low outlet pressure alarm on district regulator DR-302 at Pakenham. Outlet pressure was falling towards the low limit that would affect supply to around 3,000 customers on a cold night. The operator on duty acknowledged the alarm, dispatched Ravi Prasad, and received a call back at 10:05 pm that the pilot line had iced and had been cleared. The next morning Darren Okafor found that the log entry was incomplete, the asset register note did not mention the follow-up, and the handover to the night shift did not record the event. He wants you to reconstruct the record correctly and to explain to the shift leaders what a complete entry looks like.

Your brief. Review the alarm event from acknowledgement to restoration, correct and complete every record in the escape log and the asset register, and write a handover note that shows the shift leaders the standard expected for every alarm.

What to look for

Evidence guide

Look for times recorded in the correct sequence, a log entry that a stranger could follow, an asset note consistent with the field report, and a handover written in the order a relieving operator needs: what happened, current status, what is outstanding, who to call. The student must show understanding of the consequence of a low pressure event and who must be informed.

The student's evidence summary lists every record they created or changed in the systems named above, their notes and the tasks they ticked. Verify it against the deliverables and your own assessment tool.
