The plan to kill off a section of the ark 'accidentally' was altered. They opted for an empty room instead, where they gathered the volunteers. This was the easiest, because then they had a specific place they needed to shut down (shutting down the fans for a little while stops oxygen flow, thus killing the people). The area was probably one of many areas. We see an area like B-17 also with Vera Kane, where the tree is situated. This suggests many more of these larger open areas existed (they're also described in the books btw) and thus we only saw one of potentially 4 or 5 of them.

I'm sure they didn't just randomly pick a station to shut down. Most of the volunteers were workers, doing what they did to provide a future for the next generation. As we know working class is the most numerous, so I think while considering the old plan, they might have picked a station where people were at work (which is something they could count, seeing as the ark keeps track of all of that stuff) thus they could select rooms where a certain amount of people were, as horrible as it sounds. Ofcourse we don't have certainty of this, as this plan was never executed.

And as stated before, no gas was used, they just shut down the oxygen. I believe sinclair was monitoring it, and allerting Abby when it was safe to go back inside (when there was enough oxygen back in the air). It's a very complex thing, oxygen in space....

Hope this solves some of your questions...
