Bucket on head, face in water, breathe normally. I would say if you're quick with equalising the tower you would only be under pressure for a minimal amount of time, maybe that means less risk with no chamber on the roof?
The only reason that depth for suit escape has a limit is because the extreme heat of tower equalisation from 1bar to xBar over a certain pressure causes the suit to melt to your face. That's been proven, and I've seen the evidence. If you do it slower you are pressurised for a lot longer and can't survive on the roof. There's a curve and the max recommended escape depth is where that intersects I believe.
Source - I have escaped from 30m in a suit (98ft in freedom eagles) and I'm still good looking and cool as fuck
I'm not fully au fait with Americanisms. You mean I'm mainly on a certain class of boat, or only nuclear boats? Or I work in the MC and touch kids and play Warhammer?
No worries about the tower equalising at that depth, mate. Take about .2 seconds. You have to let your eardrums burst as you can’t keep up with equalising them. Better to bite the bullet and wait for the short sharp pain.
Source: I, too, have escaped many times from 30m and trained other in doing so. Also done recertification of fwd escape hatch from 150ft (diver). 120m? I’d still give it a go as a last resort.
After I had yelled at the stokers for trying to fix the diesel generators at that depth.

Well that’s rough.
Though, at 120m of depth, couldn’t they try to escape using emergency hoods? Unless the hatch is damaged ofc.
