3. OPERATIONAL, TRANSPORT AND STORAGE SAFETY
REQUIREMENTS
KEEP THE PRODUCT AND ITS ASSOCIATED EQUIPMENT AWAY FROM:
• Heat sources (fi re, cigarettes,...)
• Flammable materials
• Oil or grease (take a great care in the use of hand creams)
• Water
• Dust
The product and its associated equipment must be prevented from tipping over, turning over
or falling.
Always maintain oxygen cleanliness standards.
Only use the product and its associated equipment in well ventilated area.
Before the fi rst use the product shall be kept in its original package. If removed from service
(for transport, storage) GCE recommends using the original package (including inner packing
materials).
National laws, rules and regulations for medical gases, accident prevention and environmental
protection must be observed.

*for inner tightness of the shut-off valve, during transport and storage of the combination valve
mounted on a cylinder, the valid lower temperature limit is -40°C.
**maximal touch temperature of the cylinder is +45°C.
In case of combination valve storage at temperature below -20°C do not use the combination
valve until its temperature reaches at least -20°C.
For the combination valves designed to be used with mixture of gases O
operating temperature is +5°C. In normal use of the combination valve, frosting can appear on
the combination valve surface, which is caused by the gas inside the combination valve when
high pressure in the combination valve cooling when high pressure gas is being reduced to
low pressure (Joule-Thomson e ect). Check that all patient associated equipment connected
to the combination valve is via a hose of at least 2 metres length.

the temperature falls below about -6°C. A homogenous mixture is again obtained when the
temperature has raised above 10°C and the cylinder was agitated. Before use, to ensure it is
properly mixed, cylinders should be stored horizontally for 24 hours at a temperature above
10°C. If this is not practicable, before use the cylinders must be maintained at a temperature
above 10°C for at least 2 hours and then completely inverted three times or placed in warm
water at body temperature for 5 minutes and then completely inverted three times.
