Where onboard does one safely store the propane?

The same place they now store gasoline.

In a gas tank? Somehow I think that's a bad idea. Why don't you google

Conventional wisdom is that it should be stored on deck, away from any
openings that lead below or to an enclosed space. Many boats that
use propane for cooking have a sealed locker that is ventilated
overboard. I have seen others with the propane cylinder installed on
a stern bracket.
