(I have a question on UN1072 Oxygen, compressed.)
Q.
There is a cylinder of UN1072 Oxygen, compressed with a pressure of 25.9 psi. Is this cylinder a DG or a non-DG? (31 Mar 10)
A.
It is not restricted. In DGR 3.2.2.4 ?gExemptions?h, it states that: ?gGases of Division 2.2 are not subject to these Regulations if they are transported at a pressure less than 200 kPa at 20C and are not liquefied or refrigerated liquefied gas.?h 25.9 psi is equal to 178.6 kPa, therefore this cylinder is not restricted.
