How to use this checklist
- Walk the plant once per shift and tick each item as you verify it — the score updates as you go.
- Aim for 100% before you sign off; anything under 60% means the round is only getting started.
- Use the per-section bars to spot which area — biology, flows, equipment or output — still needs attention.
A general daily O&M aid for concept guidance. Follow your plant's approved SOP, safety rules and statutory monitoring for actual operation.
