oxygen unit. To prevent the reservoir and portable
oxygen unit from freezing together, always wipe the
male fill connector on the reservoir and the female
fill connector on the portable oxygen unit with a
clean, dry, lint-free cloth before filling.
9. The portable has been removed from the
reservoir and the reservoir is leaking a large
amount of liquid oxygen.
WARNING
Do not touch liquid oxygen or parts that have been
in contact with liquid oxygen. Liquid oxygen is
extremely cold (-297 °F / -183 °C). When touched,
liquid oxygen, or parts of the equipment that have
been carrying liquid oxygen, can freeze skin and
body tissue.
a. Do not attempt to reconnect the portable oxygen
unit to the reservoir.
b. Stay away from the reservoir.
c. Open windows and doors to ventilate the area.
d. Shut off stoves, heaters, and any other potential
source of flame or heat.
e. Immediately contact your homecare provider or
the company that fills your reservoir.
f.
Do not, under any circumstances, use any heat
source, such as a hair dryer, to try to melt ice build
up on the portable oxygen unit or the reservoir.
g. Do not use hot or cold water to try to melt ice
build up. The water may freeze at the site of the
leak, holding the valve open and prevent the
connector from closing.
h. Do not walk on areas exposed to liquid oxygen
for 60 minutes after frost disappears.
