Fireproof


Monolithic domes are inherently fireproof. The outer outer shell is not fire proof, but it is only a thin piece of touch fabric (I have a piece from when I planned to build one). Inside that is the polyurethane sprayed insulation in a 4 inch thickness. This stuff will burn when an actual flame is up against it, but without a blow torch or forest fire on it will only smolder. Inside that is 3-6 inches of concrete, which of course is impervious to any normal fire, and that concrete exists with numerous cable rebar to maintain its stability. You can't burn down a monolith dome even if it exists inside a forest fire. The windows on it are covered with a steel/polyurethane shutter. None of the contents will be damaged.
