| Re: Going back on the loop ?
Colin,
My instructor hammered the message home to me that "the loop is your friend", so I would probably not have gotten off the loop in the first place. Nevertheless, in your scenario I would either (depending on the gases available) flush the loop (if DIL breathable at that depth), or, switch to CCR and check what is in the loop & add enough O2 to be able breathe it. More likely I would go 1) AND 2) before switching. That allows you check the loop before you breathe it (while on OC). In case you don't trust the results, you just stay on OC and follow your tables. You may have to "suck" the loop empty before you breathe the loop again. It all depends on the situation.
All this is somewhat mute, as nobody knows how we would react under stress ... |
