Compressed and liquid oxygen
Compressed and liquid oxygen are generated by rectification at low temperature from atmospheric air. Compressed oxygen is used for metal cutting or welding and other technical purposes. Oxygen is not toxic, inflammable and non-explosive. Being a strong oxidizer, however, it accelerates the ignition of other substances therefore only safe materials are to be used having a contact with oxygen.
Packing: compressed oxygen stored in steel cylinders up to 50 dm3, operating pressure up to 20.0 MPa, transported in jacketed cylinders. Cylinders must be placed vertically or horizontally with wooden or rope insertions. Liquid oxygen stored in Duar vessels or cryogenic tanks.
