One might think you guys were talking about storing mixed thermite or ANFO given the tone of imminent danger. Light a wad of fresh clothes dryer lint and compare it to nitrate film. You'll probably switch to a clothes line. Yeah, probably not a good idea to store it in a cardboard box under the curtains in your kid's bedroom, but certainly not worth getting your panties in a bunch if stored properly in a fire resistant container away from flammable materials and ignition sources. What amazes me is that someone can be so scared of nitrate film, but have no qualms about pulling a car in their garage that holds 120lbs of gasoline right under their master bedroom. Strain at a gnat...
