When in normal times the import documents binder should be in your fireproof safe.
When in normal times you go to work, school, shopping, whatever and your important documents stay home. Not just theft but what if the house catches fire, or the drug addict down the street drives into it (happened to my house), you want that binder and anything else valuable to be in a safe place. A secondary advantage of the safe and the valuables being in it is they stay organized should you be faced with the bug out situation. Simply open safe, grab the kit and go. No running around the house gathering the items.
I then keep my not as valuable bug out gear next to the safe so.
