Where each standard applies
One plant. Seven checkpoints.
Standards make more sense when they're tied to the equipment they govern. This is the line in the animation above, unit by unit: what's checked, where, and why it matters. Click any unit to find it in the plant.

Why it matters
Caught at step 3, not at the audit.
A reflux setpoint gets nudged on night shift. No change record. On paper nothing is wrong until an auditor or an incident finds it, months later.
With the check sitting at the column, the batch is held as soon as the change happens. The risk is raised, the change goes through MOC, and the decision is in the log before anyone asks for it.
- C-201 reflux ratio 2.4 → 1.8
- MOC check fails · batch held · RISK-0142 raised
- Shift engineer opens MOC-031 · HAZOP node 7 reviewed
- MOC-031 approved · batch released
- Decision logged · ISO 27001 evidence ready
