I think I seen this somewhere before. It was a fully involved house fire that was a total loss for the homeowner, including the gun safe and it's contents shown here, wasn't it? And if memory serves me, he shared that photo with the maker of a thermal resistant safe to show what can happen to even a regular multiple layer reinforced safe when it is subjected to thermal assault at over 3000°F over a period of hours during a fire.
Fire insurance = Essential
Constant precautions and safety checks for home, garage, vehicle etc... = Priceless.
