Oliver, you must have heard that in Central Florida, where "taking a hit" has a diferent meaning. The truth: even after you have stopped breathing the oxygen, you can still tox for a few more minutes. What we do when coming out of a habitat where we have been at high PPO2 is take a ten minute air break in the habitat before returning to the water. I think what the person who told you this, probably a mixed gas instructor, was misquoting , is what I said, rather than that the air would tox you.Some of these guys have the IQ of a pet rock. A red neck once told me that a rattlesnake bites twice - once to warn you, and then the second time it poisons you. My advice to you: you have been bitten by the dive instructor/red neck once - DO NOT LET IT HAPPEN AGAIN. Technical diving can kill you , listening to dumb assholes is the first step to getting killed. - G On Fri, 23 Feb 1996, ode@ll*.go* (Oliver Edwards) wrote: >Recently I spoke to someone who claimed that 02 toxicity hits could be >triggered by taking air breaks.
