Vacuum suits and oxygen.
After watching all 6 seasons multiple times (and just starting to read the books), why are they always running out of air?
You'd think there would be backup systems. And emergency backups.
Bobbie Draper and Naomi both hop into vac suits with no/low oxygen, like "Oops, someone forgot to fill it." Why isn't there an automatic refill system that pulls oxygen out of the room they're in while the suits are being stored/charged?
I get that the authors needs low oxygen moments. But a couple hundred years of Belter ingenuity probably would have given them auto-refilling systems for vac suits.
