Just out of curiosity, FlIrishman, just exactly what qualifications and practices would you consider to be "safe enough?" I've reread Mike's post and I see no claim of perfection... on the contrary, I see a healthy caution expressed for oxygen handling. I guess I'm just surprised at your reaction to a sane post from a highly qualified and respected mixed-gas professional.FlIrishman:I'm Glad to Hear that your so PERFECTLY QUALIFIED! I'm also glad that your way up north and I'm down here in FLORIDA!
