The cylinder material, label or paint are burnt or blackened or
the paint has melted.
A clear allocation of the compressed oxygen cylinder is not
possible because the label is illegible.
If a clear-cut assessment of the damage is not possible, then
Dräger should be consulted to clarify the subsequent course of
action.
If the date for the periodic test has been exceeded, the
compressed oxygen cylinder may not be filled or used. A periodic
test must be arranged.

Transportation
Secure compressed oxygen cylinders against falling over and slipping,
and against heat, chemicals and fire.
For transportation, leave a residual pressure of 2 bar in the
compressed oxygen cylinder.
Make sure that the lock nut closes the
valve connection.
6
Storage
The valve must remain closed during storage. The valve must not
remain open when the compressed oxygen cylinder is fully
depressurised. Dräger recommends leaving a minimum pressure of
2 bar in the compressed oxygen cylinder. Dirt, dust and moisture get
into empty compressed oxygen cylinders with an open valve. In this
case, send the compressed oxygen cylinder to Dräger to be checked.
Only store compressed oxygen cylinders in designated, well ventilated
storage areas. Full and empty compressed oxygen cylinders must be
stored separately.
Check stored compressed oxygen cylinders regularly (at least once a
month) for signs of leakage or other problems.
