Caution: Use the EMS 20 only as directed
by your doctor.
Keep ammable materials away from
this equipment. Aerosol sprays, oils and
grease, including facial creams and petroleum jelly, ignite easily and may burn
rapidly in the presence of oxygen.
Smoking while wearing an oxygen cannula can cause facial burns and possibly
result in death.
Removing the cannula and placing it
on clothing, bedding, sofas, or other
cushion material will cause a ash re
when exposed to a cigarette, heat source,
spark or ame.
If you smoke please: (1) turn off the
portable, (2) take off the cannula, and
(3) leave the room where the device is
located.
In the event of an accidental tip-over,
immediately but cautiously return the
unit into an upright position if possible.
If any liquid oxygen is escaping, leave
the area immediately and call your
healthcare provider. Do not attempt
to move the unit or stop the liquid
oxygen from escaping.

Do not allow untrained personnel to
handle or operate this device.
Use of this device is prohibited on com-
mercial passenger and cargo air ights
by the Federal Aviation Administration.
The unit contains liquid oxygen which is
extremely cold, almost 300°F (-184°C).
Exposure to such a low temperature can
cause severe frostbite.
Liquid and gaseous oxygen, though
nonammable, cause other materials to
burn faster than normal. This hazard,
along with the low temperature of liquid
oxygen, warrants certain safety precautions.
