Three trauma dressings used overnight were never replaced. Rosa’s start of shift count finds it, and A12 is Restricted until they are.

1. 06:40, the night’s handover. 06:40 at Station 4. Paramedic Rosa Okafor scans the QR tag on ambulance A12. The night shift used trauma dressings on case 2207. The stretcher and defibrillator are both close to service. One tap opens the start of shift check.
2. Walking round A12. The same framed walkaround as every vehicle: an outline at each position, live camera only. Each photo is stamped with the time, GPS position and heading, so the record shows the walk happened. On the dashboard, A12’s photos are filed by position.
3. Lights and siren. Every walkaround checks the emergency lights and siren. The crew switches everything on and photographs the lights running. Each light and each siren tone is passed or failed. A fail restricts A12 and needs a photo. The results land in the check record with the photo beside them.
4. Oxygen. Oxygen first. Rosa photographs the main cylinder’s gauge, then reads every cylinder against the minimum. Each pressure lands on the dashboard with a bar showing its margin over the limit.
5. Services coming due. The defibrillator runs its self-test, and Rosa photographs the screen as proof. Pads expiry and the service dates for the defibrillator, stretcher and stair chair are checked on board. The stretcher is due for service in 9 days. Alerts shows it with its history from the equipment register.
6. Three dressings short. Rosa counts the consumables cupboard by cupboard against A12’s par levels. Trauma dressings: 5 of 8. Below par on this item restricts A12, and the app says so at once. A box of gloves short is recorded but does not restrict. The service decides which shortages matter.
7. A step light out. In the cab, Rosa reads the odometer with a photo and checks the radio and data terminal. The rear step light is out: a minor defect, with a photo. On its own it does not restrict A12. It lands on the defect board for the workshop to pick up.
8. A12 goes Restricted. Rosa submits the check: 30 results, 11 photos and one defect. No signal in the plant room. It is saved on the phone and sends itself when signal returns. The board shows A12 Restricted until the dressings are restocked, with every reason listed. The fleet manager books the step light in with the auto electrician for Thursday.
