I suggest you sit down and prepare an emergency contact list. This discussion is always good, necessary and free.
Once you establish this then work on a basic scenario that could apply to your daily life...what you expect to do, what she should expect you to do, what she expects to do and what you expect her to do.
A CERT class can also make the crazy aspect go away. I recommend them for this aspect alone.
A reasonable discussion of the news disasters which we have an abundance this year should also play a part of the intro to getting prepared...question back "what if I am not standing next to you"?
Much of getting prepared is not the stuff, but the plan. The stuff is fun but stuff alone will not get the job done.
