Depends. If your tank was not overfilled and the pressure relief valve works
properly, the relief valve should rupture when tank temp (as opposed to
ambient air temp) exceeds about 125 F. Otherwise, who knows? Conidering the
unknowns, I like to leave a buffer and keep the tank below 100 F or so.

If you have a two-guage regulator and you want to be extra cautious, you can
use it to monitor the tank pressure and make sure it stays well below the
burst pressure of the relief valve. The safety relief pressure is usually
stamped into the face of the valve. Mine says 3000 psi.
