Can fire-protected gun safes sometimes survive nuclear blasts?
Technically, the fire protection comes from lining the safe with a rock-like material that contains moisture. External heat releases the moisture to either cool down the interior, or dampen any flammable materials. Without this protection, the safe would become an oven. In a nuclear blast, either the heat from the explosion would melt the safe, or if farther away, render the safe too “hot” with radioactivity for you to use–your survival is unlikely, if you’re that close .
