No. 11-0168\nDear Mr. Zahriya:\nThis responds to your letter requesting clarification of the Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171-180) applicable to the shipment of compressed nitrous oxide and\ncompressed carbon dioxide in non-specification cylinders. Specifically, you ask if aluminum\nchargers with a capacity of 10.2 mL that are filled with 8 mL or 8 gms of N20 and CO2\ncomply with § 173.306(a)(1) of the HMR.\nThe answer is yes. Under § 173.306(a)(1), a compressed gas placed in a non-specification\ncontainer with a maximum capacity of four fluid ounces (7.22 cubic inches) or less may be\ndescribed and transported as a limited quantity when it conforms to the provisions of this\nsection. Note that the four fluid ounce (7.22 cubic inches) limit applies to the capacity of the\ncontainer, not the volume of material contained in the container. This section excepts a\nlimited quantity package from labeling, unless offered for transportation by air, and from the\nplacarding and specification packaging requirements under the HMR. Additionally, the HMR\npermit the shipment of compressed nitrous oxide and compressed carbon dioxide by all modes\nof transportation.\nI trust this satisfies your inquiry. 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 2>>>\n\nDrakeford, Carol n From:\nINFOCNTR (PHMSA)\nSent:\nMonday, July 18, 20114:10 PM\nTo: Drakeford, Carolyn (PHMSA)\nSubject: FW: request for interpretation\n5i1l\\l~rts\n~173. 30(0\nL..,;M,'.f.ed Qu\"ttI-i+;~s of -.....\"..'Wur-eS9:'J\nG\"Ctse s II -0162>\nHi Carolyn,\nWe received the following request for a letter of interpretation at the HMIC.\nThanks,\nVictoria\nVictoria Lehman\nHazmat Information Center (HMIC)\nhttp://phmsa.dot.gov/hazmat/info-center\n(202) 366-1035\nFrom: Dan Koh [mailto:dan@unitedbrands.us)\nSent: Saturday, July 16, 2011 9:05 PM\nTo: INFOCNTR (PHMSA)\nCc: Jimmy Zahriya; leemun yee; Patrice Hernandez\nSubject: request for interpretation\nTo Whom It may Concern,\nI spoke with Andrew in the DOT CS center and he advised us that we should contact the DOT Info Center for further\ndetailed explanation of Section 173.306 (a) (1)\nSpecifically, we fill 10.2 ml aluminum chargers with 8ml or 8gms of N20 and C02.\nTitle49:Transportation\n§ 173.306 Limited quantities of compressed gases.\n(a) Limited quantities of compressed gases for which exceptions are permitted as noted by reference to this\nsection in § 172.101 ofthis subchapter are excepted from labeling, except when offered for transportation or\ntransported by air, and, unless required as a condition ofthe exception, specification packaging requirements of\nthis subchapter when packaged in accordance with the following paragraphs.
