The compressed oxygen cylinder in question is no longer regarded as Restricted when the pressure of the Div. 2.2 gas does not exceed 200kPa at 20℃, and is not liquid gas nor refrigerated liquid gas as written in DGR 184.108.40.206.1. When this criteria is confirmed, the gas is no more regulated, therefore State Variation USG-18 which applies to dangerous goods (UN1072) no longer apply. It is however mandatory that there must be a proof document to support that the gas conforms to DGR 220.127.116.11.1 and such a document accompanies the AWB. The AWB should bear the words “Oxygen, compressed, Not Restricted per DGR 18.104.22.168.1 as described on the attached manufacturer’s certificate”.
