Check Cold-Storage Hours Left in a Power Cut
When the power goes, the clock starts on every shelf in the house. Subtract the hours already lost and the hours still expected from each cold zone’s rated safe window, and see which zone runs out first.

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the outage margin docket: your cold storage | rated safe hours | hours already without power stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: A full chest freezer can hold a safe window many times longer than a fridge shelf, and mixing them hides the shelf that fails first. After: the outage margin docket shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Outage margin arithmetic on the rated hours, clock and estimates you supply. Not a food-safety certification, insurance determination or public-health ruling; when food has been above the safe line, follow your food-safety authority or insurer’s guidance before keeping or claiming it.

Optional AI formatting, not calculation
For this outage margin docket, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a outage margin docket. Return plain rows only: cold storage | rated safe hours | hours already without power. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: cold storage | rated safe hours | hours already without power. No AI response is executed as code.
