Stuck on after reaching pressure about 30% of the time. There is an additional pop off valve that lets go well before the tank could fail. It's loud and exciting, but not like the tank splitting I bet!

Come to think of it, saw the same effect with a two stage compressor that had a bad head gasket - second stage pressure leaked into the first stage circuit and popped the first stage pop off. That was even louder
