Ahoy Daniel,
You have an interesting point. So far though, I have not read of any "domino" effect per say of one torpedo setting off another. This would have definitely been an issue looked upon early in the design faze of the torpedoes. There were a number of reasons for prematures. Prematures were most often a result of the magnetic exploder being set too fine resulting in the fish going off for any reason once it armed or got even near a ship much less under it. The firing pin issue was another problem in itself but unless a piece of shrapnel actually hit the pin, it probably wouldn't be set off by an explosion. I'll keep looking out for anything on the subject. I've also read of Skippers counting between firing, weather of not this was part of the reason, I don't know for sure. It might have been part of their firing solution.
