Warning Nitrogen and argon vapors in air may dilute the concentration of
oxygen necessary to support or sustain life. Exposure to such an oxygen
deficient atmosphere can lead to unconsciousness and serious injury,
including death.

Warning The Dura-Cyl/Cryo-Cyl Series, with its stainless steel support
system, is designed, manufactured, and tested to function normally for
many years of service. MVE does not suggest or warrant that it is ever safe
to drop a liquid cylinder or let it fall over in oxygen or any other cryogenic
service. In the event a liquid cylinder is inadvertently dropped, tipped over,
or abused, slowly raise it to its normal vertical position. Immediately open
the vent valve to release any excess pressure in a safe manner. As soon as
possible, remove liquid product from vessel in a safe manner. If the vessel
has been used in oxygen service, purge it with an inert gas (nitrogen). If
damage is evident or suspected, return to MVE prominently marked
"LIQUID CYLINDER DROPPED, INSPECT FOR DAMAGE".
Warning Before removing cylinder parts or loosening fittings, completely
empty the liquid cylinder of liquid and release the entire vapor pressure in
a safe manner. External valves and fittings can become extremely cold and
may cause painful burns to personnel unless properly protected. Personnel
must wear protective gloves and eye protection whenever removing parts or
loosening fittings. Failure to do so may result in personal injury because of
the extreme cold and pressure in the cylinder.
