I used to pack shelves for a supermarket and I believe at the time (~15 years ago) we had a two hour window in which perishables could be out of the fridge. Usually we'd wheel out pallets from the stockroom fridge or freezer onto the floor, move all the boxes off the pallet into their rough locations on the floor, and then pack each box into the fridges sequentially (effectively batching up the sorting/locating/carrying work). If stock sat on the floor without getting into the fridge for more than two hours, or in the rare occasion there was a power outage and the fridges or freezers were out for more than two hours, stock had to be written off.

All that to say the allowed timeline might be longer than you expect (or desire)!
