Freezer failure plan and door map
List what is in each freezer, mark how much each box matters, and print two sheets: a large-print door map to tape on the freezer, and a freezer-down sheet with contacts, where to move things, the order to rescue boxes in, and a log.

This freezer
Build from a LimsRat CSV
Locations named like Freezer 2 · Rack 3 · Box 7 become a freezer, rack and box, with sample counts. LimsRat keeps locations as one flat list, so this only works when they are named that way. Anything it cannot split is listed for you to place by hand. Boxes are added to what is already here.
Print and share
The sheets print for the freezer shown. The CSV lists every freezer, boxes in rescue order.
Freezers and files
Save file keeps every freezer, priority and contact in one small file. If you close the page without saving, the plan is gone.

Priority is yours to set: 1 irreplaceable, 2 hard to replace, 3 replaceable. The page never guesses, and boxes with none set are listed last.

How to use it
- Name the freezer and choose its type: upright, chest or fridge-freezer.
- Add each shelf (or layer, for a chest freezer), then the racks on it, then the boxes in each rack with an owner and a line about what is in them. Or open a LimsRat Export CSV to start from your data.
- Set a priority for every box: 1 irreplaceable, 2 hard to replace, 3 replaceable. This is your call, and it is worth making with the people who own the samples.
- Fill in the contacts and where things can be moved to.
- Print the door map and tape it to the freezer. Print the freezer-down sheet and keep it where the whole lab can find it.
- Save the file to keep your plan. Check it a couple of times a year, since boxes move.
Questions
Does anything I type get uploaded?
No. This page does all of its work in your browser. It has no account, no upload and no server for your data. It sets no cookies and stores nothing in your browser. Your plan is not kept anywhere, so save a file to keep it.
Is this safety advice?
No. It is a planning aid. It does not say what temperature or length of time is safe for any sample. Follow your institution's own freezer failure and safety rules and contacts.
What is a freezer door map?
A large-print sheet taped to the freezer door that says what is on each shelf and rack: the box, who owns it and how much it matters. Someone who does not know your freezer can find a box quickly.
What is on the freezer-down sheet?
Contacts, where to move things, the boxes in the order to rescue them with a tick column, a log table for times and temperatures, and a line for notes for the follow-up report. These are the parts that freezer failure procedures from universities commonly include.
How are the priorities decided?
You set them. 1 means irreplaceable, 2 means hard to replace and 3 means replaceable. The page never guesses a priority, and boxes with none set are listed last.
Can I build it from a LimsRat export?
Yes. Export CSV from LimsRat and open it on this page. Locations named like Freezer 2 · Rack 3 · Box 7 become a freezer, rack and box, with the number of samples in each box. LimsRat keeps locations as one flat list, so this only works when they are named that way. Anything the page cannot split is listed so you can place it by hand.
How do I keep my work?
Use Save file to download a small file with all your freezers, priorities and contacts, and Open file to load it again later. If you close the page without saving, the plan is gone.
Is a printed sheet an official record?
No. It is a planning aid. Follow your own lab's and institution's rules for records and procedures.
Keep your samples, and where they are, in LimsRat
LimsRat is a sample tracker for small labs that keeps your data on your own device, with no account. Name your storage locations like Freezer 2 · Rack 3 · Box 7, and you can re-make this sheet any time from your Export CSV.
LimsRat holds the samples and their locations. The layout, priorities and contacts on this page stay in the file you save.
