And of course it's not just toxic; the fire risk is the other reason you don't want to fill a room with pure O2. As NASA sadly learned in Apollo 1.

- taxicabjesus 5y agoNASA originally spec'd a mixed gas atmosphere for Apollo, it just got too heavy. After the fire in Apollo 1, they switched to mixed-gas at launch, with this gradually bleeding out to pure O2 as the mission progressed. This was discussed in my comment in my linked submission.
- sandworm101 5y agoNasa did worse than that. To simulate space they pressurized Apollo 1 to one atmosphere above external pressure. So they were at two atmospheres of pressure, which is ironically about the same pressure as the hyperbaric oxygen therapy used in the OP. The patients in the OP were using masks.
