As I get it the anh.HF cylinder has liquified gas.Hence the HF will be in liquified form and one should not take this as gaseous form to start with. Whatever the reaction takes place will give out Hydrogen in gaseous form and hence will lead to pressure build up.

In either case there will be fewer gas molecules in the cylinder and the pressure will go down and not up. Therefore, I agree with Jay (although it pains me to no extent
), that the tank ruptured because of the wall thinning. James A.
