Specifically, you ask whether Boost Oxygen®\ncanisters—which contain greater than 95% oxygen—should be classified as “UN3156,\nCompressed gas, oxidizing, n.o.s. (oxygen), 2.2” or “UN1072, Oxygen, compressed, 2.2.”\nUnder § 173.22, it is the shipper’s responsibility to class and describe a hazardous material. This\nOffice does not normally perform this function. The hazard class is determined based on the\npredominant chemical composition and hazard properties of the material as it is being offered for\ntransportation.\nHowever, it is the opinion of this Office that Boost Oxygen® is at least 96% molecular oxygen\nand should be described as accurately as possible by the proper shipping name. If this\nunderstanding is correct, under “UN3156,” this material would be described as “Compressed\ngas, oxidizing, n.o.s. (oxygen), 2.2,” while under “UN1072,” this material would be described as\n“Oxygen, compressed, 2.2.” The “UN3156” identification number allows for other oxidizers to\nbe present, potentially with molecular oxygen being in the minority of the mixture.\n\n<<<PAGE 2>>>\n\nAt a minimum of 96% molecular oxygen content, oxygen is the dominant component of the\nmaterial and, therefore, is best suited to be classed as “UN1072, Oxygen, compressed, 2.2.”\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nT. Glenn Foster\nChief, Regulatory Review and Reinvention Branch\nStandards and Rulemaking Division\n\n<<<PAGE 3>>>\n\nPollack\n21-0068\nFrom: INFOCNTR (PHMSA)\nTo: Hazmat Interps\nSubject: FW: FW: info regarding Boost Oxygen\nDate: Tuesday, June 29, 2021 4:49:40 PM\nAttachments: SP 10704-EX 05.06.2020.pdf\nSDS- Boost Oxygen Medium and Large Cans.pdf\nBoostOxygenLabel 2019.pdf\nBOOST_22oz-Can_Natural_4-19_REFERENCE.pdf\nHello,\nAttached and below is a request for letter of interpretation.\nThanks,\nJonathon, HMIC\nFrom: Cliff Croft <cliff.e.croft@gmail.com>\nSent: Tuesday, June 29, 2021 1:32 PM\nTo: INFOCNTR (PHMSA) <INFOCNTR.INFOCNTR@dot.gov>\nSubject: Fwd: FW: info regarding Boost Oxygen\nCAUTION: This email originated from outside of the Department of Transportation (DOT). Do not click on links or\nopen attachments unless you recognize the sender and know the content is safe.\nI would like to get a formal ruling on the classification of Boost Oxygen (SDS attached). The\nmanufacturer is classifying as UN3156, Compressed gas oxidizing n.o.s for a material which is\ngreater than 95% Oxygen compressed. By selecting the UN3156 description the manufacturer is\nutilizing DOT-SP10704 (attached) which allows for labeling and documentation exceptions for\nground transportation that are not available for a UN1072.\nI would like to get clarification on whether the description selected manufacture is correct and\nacceptable or if the description should be UN1072 Oxygen Compressed.\nThank you,\nCliff Croft\nKajuligan, Inc\nS881 Donny Hill Rd,\nElburn, IL 60119\n913-522-1036","truncated":false,"body_characters":3422}
