Fire is something I am concerned about also. All of my negatives and prints are in one location, my house. The negatives (mostly 35mm) are in 3 ring binders with contact sheets (when I do them) in front of the negatives with the developing notes behind. I'm up to 6 2" binders which take up a lot of room. (I'm sure others have many more negatives) Do they make fire safes that large? Are they reasonably priced?
