DC 20590 Ms. Nina Ximena Artime Hazardous Control Inc. 8600 NW 72 Street Miami, FL 33166 Ref. No. 12-0076 Dear Ms. Artime: This responds to your March 20, 2012 request for clarification regarding the transportation by vessel of compressed oxygen under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask ifyou are required to package cylinders containing "UN 1072, Oxygen, compressed, 2.2, 5.1" in an outer package that meets the "DOT31 FP" specification. The answer to your question is no. In accordance with§§ 173.302(t) and 173.304(t) compressed oxygen and oxidizing gases transported by aircraft must meet certain requirements. Specifically, these requirements include placing the cylinder in a rigid outer packaging meeting the requirements of§§ 173.302(t)(3) and 173.304(t)(3) respectively. The requirements in§§ 173.302(t) and 173.304(t) are applicable to shipment of compressed oxygen by aircraft, not by vesseL I hope this answers your inquiry. If you need further assistance, please contact this office at (202) 366-8553.

I need to ship by ocean in a full container 1 Box- UN1072, my question is: Do we need package in an outer package that meets the DOT31 FP specification? Cylinders containing Oxygen, compressed, UN 1 072; Compressed gas, oxidizing, n.o.s., UN 3156; Liquefied gas, oxidizing, n.o.s., UN 3157; Nitrogen trifluoride, UN 2451; or Nitrous oxide, UN 1070 must be packaged as required by 49 CFR 173.302(f) and 173.304(±) and be placed in a rigid outer packaging that meets specified flame penetration and them1al resistance requirements as prescribed in Appendices D and E of 49 CFR Part 178. This requirement does not apply to cylinders containing medical-use compressed oxygen transported in accordance with US Variation 15. Thanks a lot for your continuous support. Wishing you a very happy Saint Patrick's month, full of good luck! Thanks for choosing Hazardous Control as your company for all your HazMat needs! Safe and prevention is our principal goal!
