Process Boundary Stop-Work

Process boundary stop-work samples open maintenance jobs and confirms none of them open the process. The technician writes the as-found reading and compares it with the last one on the asset. A line break, a relief-device lift, or a bypassed interlock is a permit, not this task. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Sample open maintenance work orders on covered equipment
  2. Confirm none of them break a flange, lift a relief device, or bypass an interlock
  3. Confirm a permit path exists for line breaks and confined-space entry
  4. Check that isolation points named in those permits match the field
  5. Stop a work order that starts to read like an operating procedure

Why This PM Exists

Process boundary stop-work samples open maintenance jobs and confirms none of them open the process. The technician writes the as-found reading and compares it with the last one on the asset. A line break, a relief-device lift, or a bypassed interlock is a permit, not this task. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

What Skipping It Looks Like

The permit board is empty and a work order still says 'crack the flange and see'. The round still closes, the number never lands on the asset, and the next person inherits a guess. A line break, a relief-device lift, or a bypassed interlock is a permit, not this task.

Setting the interval

Monthly. A job that starts to read like an operating procedure is stopped. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.

Common Questions

How often should this PM run?
Monthly. Monthly. A job that starts to read like an operating procedure is stopped. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
How long does it take?
Budget about 1.0 hour for a technician working to the standard procedure. ChatterFix uses that estimate for capacity planning, then learns your plant's actual time from completed work orders.
What happens if we skip it?
The permit board is empty and a work order still says 'crack the flange and see'. The round still closes, the number never lands on the asset, and the next person inherits a guess. A line break, a relief-device lift, or a bypassed interlock is a permit, not this task.
