A safeguard tied to a job stops when the job closes. On the board, 435 ended that way.
A clamp on a sour stripper line, from the 07:02 board to the 10:00 countersign
A pinhole leak at an elbow on a naphtha hydrotreater’s stripper overhead got a bolted clamp and a fix-today job, which closed 23 days later. This is the morning the line came back.
demoThe clamp, the plant, its crew and each figure here are sample data.

1,951 lines, and the clamp sits on top with 12 days of nothing under it
Integrity engineerOvernight the agents redrew the board: 1,137 open lines plus 814 closures with no proof. Each bar is time outside a limit, safeguards drawn beneath it. The clamp’s line sits first, closed with no proof, its red gap reading 12 days, no safeguard. Chips above count 190 with no safeguard today and 56 safety devices out.

Thirty-five days outside its limit, and the job says complete
Integrity engineerIts own line spells it out. Found at 0.094 in against a minimum of 0.130 in, worked from the design pressure on the page, the wall was below its limit. A fix-today job ran 23 days and then closed. The clamp is allowed to the end of the year, and the gas and clamp checks stopped where the job closed.

Three questions about the closure, and three crosses
Integrity engineerThe test takes the job against the limit it breached. Is there a thickness reading after the repair? None; the readings ordered either side of the clamp have no record. Is there a repair record for the elbow? Only the clamp. Is the temporary fix gone? No, the removal date is blank. The record still shows a breach, so the line stays open.

Three of eight grid points below minimum, in a pit the spot reading missed
Integrity engineerThe engineer opens the source himself. The ultrasonic grid taken around the pinhole the morning of the leak reads 0.094, 0.121 and 0.118 in at three points, all under 0.130. A search of the inspection data system after the clamp went on finds nothing. The screen says no record found means none was filed, and it does not prove none was taken.

Agreed after opening all three records, then sent up
Integrity engineerThe agree button stays shut until the job, the readings and the register row are open, and the ticks beside them are his own. Once all three are ticked he agrees the closure is not proved and sends it to the superintendent. The chip now reads with the superintendent. Until she rules, the line stays open and the board keeps counting the gap.
- 0609:33
Her own three openings, and rounds she cannot drop
Unit operations superintendentHis openings do not count for her, so she opens the same three records. The drafted ruling locks the gas and clamp check, because the change record says it runs until the clamp is removed. She picks a repair date inside the unit's short outage to clean the condenser, and the reason temporary fix still in place. The later turnaround date is marked past the clamp’s allowed date.
- 0709:45
Reopened, and the line redraws with a safeguard from today
Unit operations superintendentThe line gains a new safeguard bar, signed, starting today, and a repair-date mark. The chip reads safeguard signed, no round logged yet. A new job is drafted for the planner to enter. The repair date sits 40 days out, past the 30-day limit for a running decision, so it waits for process safety and has not taken effect.

A 40-day running decision, countersigned after two records
Process safety engineerProcess safety reads two things first: the temporary change record and the round log. Her ticks sit beside both in the sources list, and the line's trail records each opening and then the countersign. Only then does the running decision take effect. The panel now hands the next step to the maintenance planner, who drafts the booking.
- 09After the countersign
The new spool job tops the list, and closing it will not end the line
Maintenance plannerThe new job leads the planner's list, priority fix today: replace the elbow spool, remove the clamp and read the wall after. The page says the maintenance system keeps its own jobs and this solution only reads it. Closing the job there is his call and changes nothing here. The line ends only when a reading, a repair record and the clamp's removal are accepted.
