From what I remember reading of it the combination of temperature and

the valves were removed. They ruptured during their first refill after

their not like a bomb. Supposedly makes a hell of a noise and lots of
water thrown all over the place. But the energy is disapated in the
water.


Not necessarily. The water helps contain any fragments but is actually
there to cool the tank during filling.

There is a LOT of energy in a tank that has 3000 psi in it.

One example:

Note the bottom photo of the water tank that the scuba cylinder was in
at the time.
