Can they not open a hatch if it’s on the surface?
Water would be a problem still, but not suffocation, if so.

Nope. The hatch is bolted from the outside. They can’t do anything from the inside and are utterly dependent on someone outside with a power socket wrench to unscrew each of the 17 bolts holding the hatch on.
There are some design flaws with this thing.
