Do passengers also need to undergo decompression before exiting the craft?
- erik_seaberg 3y agoNo, the crew remains at 1 atm and the hull bears the pressure difference. Ocean pressure at the Titanic’s depth is over 400 atm (6000 psi!) but the oxygen level in normal air becomes toxic even at lower pressures. Technical divers use nitrox mixes, and the hyperbaric chamber record is 70 atm for a couple hours by breathing 0.5% oxygen and 99.5% hydrogen. (This mix can’t even explode, not enough oxidizer.)
