There are a lots of things you can survive solo under water. Toxing from high PP02 is NOT one of them. Toxing is almost a death sentence with an experienced, trained and proactive dive buddy. There is no self rescue to that scenario - tox, drown and die. If you get entangled and are on the hot mix, which could well be over 2.0 PP02, for a couple of minutes at depth you will not be walking out of the water.
