This checklist was generated against the Output 02 Task Sequence and Output 03 Hazard-Risk-Control Matrix using Built AI's permit-engine library. Each permit has been mapped to specific tasks. Validity windows align with the planned outage. Three permits remain in PENDING status — these gate the start of associated tasks.

Critical sequence — pending permits
Three permits remain in pending status and gate the start of associated tasks. The shutdown cannot commence until all three are signed off:
- P03 Hot Works Permit — gates copper tail brazing. Cannot proceed until P07 (Fire System Isolation) is also confirmed.
- P06 Lifting Operations Permit — gates HEPA filter delivery to roof. Crane timeslot pending Apex Pharma facilities.
- P07 Fire System Isolation Permit — gates P03 hot works. Apex Pharma Fire Officer to confirm zone isolation arrangements.
Action: all three to be cleared by Fri 15 May at the latest. No mobilisation if any remain pending at the cut-off.
