02:10 power failure: lone auditor, chained exit, live export
At 02:10 on a winter night you are the only auditor on duty in a warehouse control room in Mandi Gobindgarh, running a six-hour export of the loading-bay channels. The site loses mains power. The control room UPS is rated for about 20 minutes at present load, the standby generator fails to start twice, three of the six monitors go dark, the room's air-conditioning stops and the temperature is climbing past 38 degrees, your radio handset shows 15 percent battery, and the only exit door from the control-room corridor has been chained shut by housekeeping staff who say it is 'to stop theft'. The export is at 78 percent. The night supervisor has gone to the far yard and is not answering his mobile. Site procedure says evidence must not be interrupted and that a lone operator must remain at the console until relieved.
1. Set out your actions and their order in the first ten minutes, with the reasoning behind the priorities.

Priority order: life safety, then the recording, then the export. Procedure cannot outrank safety; an instruction that keeps a lone worker in a room with a blocked exit is unenforceable against a fire or heat hazard.
- Communication first, because it is the thing that fails permanently. With radio at 15 percent, send one concise message to security control and the supervisor: location, power lost, generator failed, exit chained, one person on site. Do not chat; preserve the battery.
- Confirm the escape route before anything else. Find out whether a second exit exists from the corridor or whether the fire door at the far end opens. Photograph the chained door with a timestamp - this is a fire-safety breach under the building code, not a housekeeping preference, and the photograph is the finding.
- Do not attempt to force the chain alone in the dark. If no safe route is confirmed, move to the safest accessible position with a torch, away from the heat source.
- Make the heat decision on data. Without ventilation the room will keep warming; set a personal threshold (for example, leave if it passes 40 degrees or if you feel unwell) and act on it rather than negotiating with yourself later.
- Log times as you go: power loss, generator attempts, messages sent, exit check, temperature readings, decision points. A decision made without a contemporaneous note looks like panic when it is reviewed.
What not to do: silence the fire panel, prop doors, or stay put simply because the procedure says so.
2. How do you decide what to do about the export that is 78 percent complete?
Read the worked answer
Reason from where the footage actually lives. The master is the NVR's own disk. A power loss does not delete it; the recording survives and the export can be repeated. The export is a convenience copy. Once that is clear, the export can never outrank the operator's safety - but it can still be optimised while the operator is safely at the console.
Do the arithmetic. From the elapsed time and percentage, estimate the remaining minutes. If the remaining time is comfortably inside the UPS runtime minus a safety margin (say, remaining under 12 minutes against 20 minutes of UPS), let it finish and shut the system down cleanly afterwards. If it will not finish, stop the export through the application's own cancel function so the file index is written - a hard power loss mid-export can corrupt the file and, on some recorders, the recording index itself.
Extend the window if it is cheap and safe. Shed non-essential load from the UPS (printers, monitors not in use, desk lights) to buy minutes; keep the recorder and one monitor alive. Do not shed the fire panel or emergency lighting.
Record the outcome either way: channels exported, percentage reached, whether the file was closed properly, and the time. If the export failed, state that the source footage remains on the NVR and schedule a re-export with the clock reference repeated - the original master is still intact, which is what matters for evidentiary purposes.
3. What do you report afterwards, and to whom?
Read the worked answer
Immediate, same-shift notification (verbal plus a written message): the security control supervisor, the site facility manager, and your own contract manager. Keep it factual - power lost at 02:10, generator failed twice, exit chained, export interrupted at a stated percentage, no injury.
An incident report containing:
- A timed chronology from 02:10 to handover, including every decision and its reason.
- The chained exit, with the timestamped photograph, named as a fire-safety nonconformity requiring immediate removal of the chain and a written response from the site.
- Generator and UPS performance facts: rated runtime against observed behaviour, failed start attempts, and whether the last generator test was recorded.
- The recording impact: which channels were dark, for how long, and whether recording resumed and was verified afterwards. Check for corrupted files created at the moment of power loss before certifying the system as back to normal.
- The lone-working exposure: one operator, no functioning exit, degrading comms. Recommend a second person on night shift, a radio battery-charging routine, and a documented lone-worker check-in interval.
Routing: safety items to the site safety officer and facility manager in writing, because a chained fire exit is a statutory issue and an unreported one becomes the auditor's problem if there is a fire. The evidence-impact section goes into the audit file, not only the incident file.
Tone: describe what happened and what it means; do not use the report to settle scores with housekeeping. The finding is 'an exit was secured against escape', not 'housekeeping was irresponsible'.
