3.4.2 Checking the compressed oxygen cylinder
If the compressed oxygen cylinder has come into contact with

corrosive media (e.g. acid), it has to be depressurised and Dräger
must be consulted to clarify the subsequent course of action.
If the compressed oxygen cylinder had to withstand a heavy

impact(for example, because it was dropped), then it must be
depressurised and sent to Dräger for assessment.
Compressed oxygen cylinders must be discarded in the following
