I have been using a Dive type cylinder because they are easier
to
get re filled.
Last Saturday I was flying with the bottle on but the regulator
off
above a ridge trying to connect to the wave system.
About 1 hour in and 2700ft asl there was a loud pop and bottle
pressure O2 started blowing into the cockpit .
I could not turn the bottle off so I opened the DV window put a
Pan call out and got it back on the glider field in about 3
minuets .
I have never been so scared ,and I have loads of field landings
and
thousands of hours in gliders.

I had a similar experience thus summer - the connector on the MH regulator obviously had worn out over the about 20 years of use and decided to let go the connecting hose to the EDS unit.
I can't reach the cylinder inflight without an immense effort of wiggling myself, and as I was close to the rocks trying to get the first climb of the day, I just kept on flying. The oxygene pressure on the outlet of the regulator is 2 bars or less, so it can't do any harm.
