Valve Drills save lives

[waterpirate]

I am firmly in the camp of " stand by " and let the diver solve their own issue, while having the long hose pre-deployed and waiting for acceptance if needed. If not needed, re-stow and go.

Last week the DIN O-ring on my left post popped in a big BOOM!!! After the noise, i saw gas everywhere, shut the isolator on my manifold immediately, guessed the failure was on the right post, switched to my backup reg and shut the right post. My buddy saw the gas was coming out of the LEFT post (the one I was breathing from), so she shut that one as well at the same time. My reg went dry, she gave me her long hose and in less than 15 seconds the leak was stopped.

We re-opened my right post and the manifold safely, then I switched back to my reg and we went for the surface.


In total, I lost 25 bar, which means that tanks would have gone completely dry in about 1 minute.


Practice your valve drills, people, it can save your life.

Again, The dive buddy saw that the OP was turning the "WRONG" tank off.... He said " I saw gas everywhere " and was guessing where the leak was.. She "KNEW" where the leak was... Had he been turning the right tank off, She would not had to do anything... The only thing I see to do next time is to give the long hose "FIRST".... Other then that GREAT JOB...

I took cave classes from 2 different agencies and was very surprised how much attention was paid to valve failures and how detailed algorithm and actions for failures are for the diver himself and for his buddies during GUE C1 class.
Classes from another agency had these from slim to none - just valve drill...


BTW, suffered in farthest point of penetration from free flow of both regs and had both posts closed... didn't like this fact at all.


So would recommend to take a look at GUE "Valve Manual" though

A correctly done valve shutdown is just a single part of a considered plan that diagnoses and corrects the problem.

Interrupting this process can hide the true problem, and worse, lead to confusion about the team's gas resources.



For example, here is a video of the whole process. There is a lot going on here that ensures a good outcome:
