If they weren't inside the Dimensional Laboratory with an extremely efficient ventilation system, they would have suffocated to death by now.
As everyone knows, the only way to go up and down within the Dimensional Laboratory is the elevator located at the very center of the Dimension. There are no other pathways for ascent and descent, including necessary safety stairs for external access.
Oh, no, to be precise, there are stairs. The secret passage they just took down to the lowest level is made of stairs. But the problem is that these stairs don't lead directly to the surface, nor do they connect to every floor.

Beyond those twenty floors, the secret passage simply doesn't exist.
