1. Oxygen is value of when there is something to treat.
It is possible to decrease the surface interval by accelerating nitrogen washout, but this requires calculations - and a tight fitting mask [or other delivery system].
2. The oxygen tanks will not explode. They have a relief valve that will vent excessive oxygen pressure. It will vent this oxygen into or around the boat however. A bad situation, indeed.
So how about this... the dive ops can buy ventilators, pay my salary and let me dive free. In return, I'll intubate their customers during the surface interval. With a dose of Vecuronium, we can then easily ensure that they're getting an FiO2 of 100...
OK, that does seem a little drastic, for people who don't have a big bubble load.
