BASIC SAFTY

Mountain High Oxygen systems are designed to contain and deliver pure oxygen for the
purpose of supplemental breathing as needed for exposure to high altitudes.  They are not
intended for medical or underwater use.   Pure oxygen is a highly oxidizing gas in nature and
vigorously accelerates combustion.  It can provide a catalyst for spontaneous combustion if
not used properly and with caution.  DO NOT use any type of oil or grease on any of the
fittings, valves or cylinders.  DO NOT use the system while smoking or near an open flame.

NOTICE

The EDS model "A" operates with a standard aviator's nasal cannula for single person flight
operations up to 17,999 ft. or a face mask for flight operations over 17,999 ft. and up to
30,000 ft.  Both of these items are included with each EDS kit.   Several EDS units can share
a single cylinder and primary reducing regulator for multi-place operations.   Pilots should
refer to FAR 23.1447 to see if any restrictions apply for their use of cannula type breathing
devices in the operation of their aircraft.  Information and data in the field of flight
physiology is constantly changing and updated.  Therefore, Mountain High E&S Co. reserves
the right to correct and enhance this manual and associated documentation at any time
without notice.
