Preparation for use

3.2.1 Filling the compressed oxygen cylinder
WARNING
!
Explosion hazard!
Compressed, flowing oxygen has an oxidising effect and
causes oil and grease to ignite immediately.
The inside of the cylinder, the valve thread and the sealing
elements must be free from oil and grease.
Compressed oxygen cylinders may only be filled when they:
have a label or stamp with the test date and identifier of the

accredited inspection authority and the specified test interval has
not been exceeded,
do not show any signs of damage that could be dangerous (e. g. a

damaged valve housing, thumb wheel or a leaky valve),
are in good condition and show no signs of damage, corrosion or

moisture on the valve,
are in accordance with national guidelines.

Compressed Oxygen Cylinders
Compressed oxygen cylinders may only be filled with oxygen of the
following quality characteristics:
Purity: ≥ 99.5 vol. % O

2
Water content: ≤ 0.05 mg/L oxygen

Tasteless and odourless

The maximum permissible contaminants are subject to national

regulations, in Germany, for example:
Inert gases (N
+ Ar): 5000 ppm
2
Carbon monoxide (CO): 5 ppm
Carbon dioxide (CO ): 300 ppm
2
2
Oil: ≤ 2.5 mg/m
The compressed oxygen cylinders must be filled at the correct nominal
filling pressure as specified on the cylinder body and valve housing.
WARNING
!
Danger of bursting!
Do not overfill the compressed oxygen cylinders! They do not
have a safety valve and could burst.
To avoid overfilling, Dräger recommends the use of a
pressure relief valve on the oxygen filling facility.
The temperature of the oxygen and compressed oxygen cylinder can
increase during the filling process. This can lead to an incomplete
filling of the cylinder. To avoid this effect to a large extent, Dräger
recommends a filling pressure increase of 27 bar/minute. Check the
cylinder pressure at ambient temperature after the filling process and
top up the compressed oxygen cylinder, if required.
Observe the instructions of the filling station manufacturer.
