- Hmm... 300ft or so being uniformaly dangerous because of oxygen
- becoming oxiduous / poisonous or what ever...
-
- 1) isn't the limit more close to the 11 to 12 atm/bar's than 10 as the
- debth of 300 ft = 90 meters = 10 atm/bar's suggests...
-
- 2) about uniformality: Cousteau says in his biography something like
- this " in my opinnion a sport diver can quite safely and freely dive up
- to 90 meters with some experience though " and then he continues that
- the two of his friends claimed they could do "relatively light jobs at
- 100m" later I've red on numerous occaisons that different persons have
- diven up to 130 meters, that's roughly 433 ft and stayed alive
-
- - - - ALL THIS ON AIR and considerably "normal" equipment - - -
-
- (Cousteau & co. ofcourse used the "aqualung" bi-circulator konsept but
- on air too... one of them died after signing a plate in 127m on air !)
-
- so, all this suggets that the real limit of oxygen poisoning is closer
- to the 12 atm than 10 or is there a certain physical law or clause that
- suggests otherwice... but then again... the physicists can't figure out
- why a chopper flies !!!
-
- ps. what I've heard, in most cases the nitrogen starts to be a real
- problem around 70m (233ftor so...) dunno abouty heavy drinkers though
- ;-)
