You're up.

For certain directions of down, yes. What's with the suit? Doesn't the bomb factory have an atmosphere?

Their atmosphere is almost pure nitrogen. So, spacesuit required.

My suit's an oxygen concentrator. I won't be able to
go in there.

Are you disappointed?

I never complain about conditions that get me
out of work.

We already know that Sam's “spacesuit” is not very airtight, it has rather oversized filters and a battery, and the oxygen concentration Sam needs is most likely achieved by freezing it out
Mark Stanley first mentioned the composition and parameters of the atmosphere at the scene - all-nitrogen is extremely convenient for flammable automatic production facilities. He had never before described the composition and parameters of the atmosphere of Jina (where gold and diamonds are paradoxically cheap), the shuttle and the station, so it's not necessarily earth-like nitrogen-oxygen. The same divers breathe a helium-based mixture with a small fraction of oxygen, and the British journalist-populist David “Daedalus” Jones once theorized the parameters of a xenon bath where one could (for a very solid price) fly in condensed xenon-oxygen “air,” waving their arms like a bird. However, flying people have definitely not been here yet
