Something about the humidity being too high and freezing in the valve.


THIS IS PURE BS.

There is essentially NO moisture in the tank of medical oxygen - for the
same reasons there is no moisture in aviation or welders oxygen. Any
moisture or humidification in a medical stream is added at the point of
use, AFTER the flowmeter.

Any doctor, nurse, paramedic, EMT, respiratory therapist or gas vendor
can vouch for this.

Probably only a gas vendor would know.
Anybody ask one????

I was a paramedic and heavily into the equipment maintenance in our
fire department. An amusing story was that one day I was helping
another guy weld on one of the fire engine compartments. Suddenly
he stopped and said he ran out of oxygen. I said we have plenty
of oxygen and went and grabbed the thumper bottle off the ambulance.

Thank you...

I would hope that after 16 years in fire, ems, healthcare and dealing
with compressed air and oxygen in general I would know what I was
talking about.

The whole "moisture" argument is one of the silliest OWT's around.
