Companion 1000/T Liquid Oxygen System Technical Manual
Important Facts:
The possibility of fire exists when the combination of a fuel, source of ignition, and
oxygen is present (Figure 1-5). High concentrations of oxygen (air is approximately
21% oxygen) greatly enhance the possibility of combustion.
•
Obtain all replacement parts for medical oxygen equipment from the manufacturer.
•
Before servicing, clean all tools that come into contact with the oxygen system.
•
Use only recommended oxygen compatible cleaning and leak detection products.
•
Keep the Portable and Reservoir upright at all times. Secure liquid oxygen
equipment when transporting to prevent accidental tipover and spillage.
•
If a liquid oxygen spill occurs indoors, open doors and windows to ventilate the
area. Avoid sources of ignition and do not walk on or roll equipment over the
affected area.
•
Any clothing or porous material that is splashed with liquid oxygen or otherwise
absorbs high concentrations of oxygen should be removed and aired for at least one
hour away from any source of ignition.
Figure 1-5: Combustion Triangle
Keep oxygen equipment in a well-ventilated area at all times.
These
units periodically release small amounts of oxygen gas that must be
ventilated to prevent buildup. Do not store liquid oxygen equipment in
a car trunk, closet, or other confined area. Do not place bags, blankets,
draperies, or other fabrics over the equipment when it contains liquid
oxygen.
Do not place the Portable unit under clothing. These units normally
vent oxygen. Placing a Portable unit under clothing may saturate
fabrics with oxygen and cause them to burn rapidly if exposed to
sparks or flame. It may take several hours for oxygen levels in the
fabric to return to normal.
WARNING
OXYGEN SOURCE
Approximately 16% required
for combustion.
Normal air contains 21% oxygen.
Some fuel materials contain
sufficient oxygen within their
make-up to support burning.
