I have a 2 hour sentry fire safe.
Great for documents. BAD, BAD, BAD for things like CDR, photos, etc. Why? Because the technology that
makes the thing fire-safe, that keeps your stuff relatively cool for 2 hours while fire burns, ALSO raises
the humidity inside the safe DURING NORMAL OPERATION (i.e., when there isn't a fire). This humidity,
plus the fact that it's a chemical, and not even water, will corrode your stuff.
