----- all firesafes rely on insulation, and the thicker that is, the longer 
it takes to heat the content to the ambient temperature. If you have a fire 
that lasts 5 hours nothing will be much below red heat inside the safe, 
irrespective of thickness. So the ratings are typically based on temperature 
rise during an hour.

----- active cooling of the content is a possibility, but I can only imagine 
solutions, I do not know of any used in practice. If you have a reservoir of 
water surrounding the safe, the temperature inside will not rise above 212 
deg. F as long as there is water available. But when that is gone, we are 
back to insulation creating a time constant.

The best solution is to select a location that is fireproof (unless someone 
deliberately tries to make a long lasting fire inside).
