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.
WARNING
Keep clear. Do not stand so any body parts extend
directly over the reservoir fill connector when
disengaging the portable oxygen unit. Contact with
liquid oxygen can cause personal injury.
WARNING
If a major liquid oxygen leak from the reservoir fill
connector occurs when you disengage the portable
oxygen unit — that is, a steady stream of liquid
oxygen — step away from the reservoir and notify
your oxygen supplier immediately. Ventilate the
room by opening windows and/or doors. Shut off
stoves, heaters, and any potential source of heat,
flame, or sparks. Stay away from the reservoir until
your supplier ensures that it is safe.
