Practical Method
- Observe. Check plant condition, alarms, flows, levels and water quality.
- Compare. Review operating targets, trends and recent changes.
- Verify. Confirm instruments with independent checks where required.
- Act safely. Follow approved procedures and make only authorised adjustments.
- Record and escalate. Document findings, actions and unresolved risk.
