A leak above the action level is found on an industrial process refrigeration system, and the repair cannot be made without shutting down the process the system serves. How much time does the regulation allow for that repair?
Correct Answer
A) One hundred twenty days from discovery when a process shutdown is required
The ordinary deadline for repairing a leak above the action level is thirty days from discovery. Industrial process refrigeration is given a longer window, one hundred twenty days, precisely because the repair may require the process itself to be shut down, and a plant cannot always stop a production line on thirty days' notice. The longer window is tied to the shutdown requirement, not granted to industrial equipment automatically.
Why This Is the Correct Answer
The regulation recognizes that some repairs on industrial process refrigeration cannot be made while the process runs, and it extends the repair window to one hundred twenty days from discovery when the repair requires an industrial process shutdown. Without that condition the ordinary deadline applies. The extension buys scheduling room, not an open-ended exemption.
Why the Other Options Are Wrong
Option B: Thirty days from discovery, with no allowance made for a process shutdown
Thirty days is the ordinary deadline. The regulation carves out a longer period for this specific situation rather than holding every appliance to the same clock.
Option C: One year from discovery, matching the deadline for a retirement plan
One year is associated with completing a retrofit or retirement, not with repairing a leak. Applying it here would stretch a repair deadline by a factor of three.
Option D: Until the next scheduled maintenance outage, whenever the plant schedules it
Deadlines in the regulation are fixed periods, not references to a plant's own schedule. An outage that never gets scheduled would extend the clock forever.
Memory Technique
Thirty normally, one hundred twenty when the line has to stop. Four times the time for four times the disruption.
Reference Hint
Leak repairs are due within thirty days of discovery, extended to one hundred twenty days where an industrial process shutdown is required.
