That's true, of course. But it would have to be a pretty doggone heavy safe to exceed the safe load rating of a modern, properly constructed floor.

Just for grins, I found this from a reputable safe company:

Let's say you have a three foot wide safe that weighs 1,000 pounds, and your floor joists span 12 feet (which is typical). This three foot by 12 foot section of the floor was designed to safely carry a live load of 3 x 12 x 40 PSF, which equals 1,440 pounds. So when placed perpendicular to the floor joists as close to the wall as possible, you are well within the minimum safety factor.
