Keeping the emergency manual safe

As explained in Chapter 1 of the book, BEING PREPARED, the term “manual” is used generically. That is, your EMERGENCY EVENT MANUAL may be in the book, or it may be saved in a notebook, folder or electronic file. The manual itself and the information contained in the manual may all be in one place or stored in several places depending on its level or sensitivity (security) and depending on the person who is to use the information. Where do you store sensitive information that would be availble for use by your helper during an emergency?
