- adastra22 3y agoI worked for NASA. That answer is wrong. The ISS and Space Shuttle have standard 15 psi atmosphere for abort-to-Earth situations, not for any reasons related to fire. A 3 psi oxygen atmosphere has exactly the same fire risk as a 15 psi atmosphere with inert gas making up the rest. Chemically, partial pressure is all that matters. Apollo 1 had an over 15 psi pure oxygen atmosphere.
