If I have advanced notice and don't have to be worried about rushing my family out of a burning house, I have the irreplaceable cards in a carrying case inside the fire safe. I can quickly open the safe and grab that case and run.

The UL fire ratings refers to the amount of time the the interior temp stays below 350 degrees at exposures of 1700 degrees. A house fire with enough fuel can burn in excess of that. Paper might not char until closer to 400 degrees but most plastics melt under 200 degrees, which is not great for slabs.
