Nice try, but the gas in the loop does not become "poisonous".
If for some reason someone is so poorly trained that they turn off the gas supply to the re-breather everytime they surface for a couple of minutes, then "forget" to turn it back on, which is a good sign of a poorly trained re-breather diver, then the gas in the loop would become hypoxic and eventualy the poorly trained diver would pass out..... and the rest is self explanatory.
Also why would any properly trained insructor be diving with a re-breather with students, other than rebreather students, and, even then most of properly trained, competent instructors dive open circuit.
If the 14 student to number is correct, 14:1 breaks every standard known.
Bottom line you can't hide from Darwin
