Specifically, you provide the example of “UN1219, Isopropanol or Isopropyl alcohol, 3,\nPG II” where Column (2) of the § 172.101 Hazardous Materials Table (HMT) lists both\n“Isopropanol” and “Isopropyl alcohol” in Roman type as PSN alternatives. You ask whether a\nshipper may use both—at the same time—for the shipping description of a hazardous material\nrequired by § 172.202 or whether the intent is to use only one at a time.\nThe intent of the shipping description requirements is to include the one PSN that most\nappropriately describes the material. For example, for “UN3164, Articles, pressurized pneumatic\nor hydraulic containing non-flammable gas, 2.2” the selected PSN must indicate whether the\narticle is pneumatic or hydraulic—it cannot be both.\nHowever, in the instance of “UN1219, Isopropanol or Isopropyl alcohol, 3, PG II,\n” the PSN\nalternatives are variations of the chemical name that describes the material itself.\n\n<<<PAGE 2>>>\n\nIn such a case, it would be permissible to show the PSN as one of the alternatives with the other\nas a chemical or technical group name in parentheses either between the proper shipping name\nand hazard class or following the basic description—see § 172.202(d)—as such a scenario still\naccurately describes the material. For example:\n• UN1219, Isopropanol (Isopropyl alcohol), 3, PG II\n• UN1219, Isopropyl alcohol (Isopropanol), 3, PG II\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nDirk Der Kinderen\nChief, Standards Development Branch\nStandards and Rulemaking Division\n\n<<<PAGE 3>>>\n\nCardez\n22-0040\nRequest for Formal Letter of Interpretation\nDate: May 3, 2022\nMr. Shane Kelley\nDirector, Standards and Rulemaking Division\nU.S. DOT/PHMSA (PHH-10)\n1200 New Jersey Avenue SE, East Building, 2nd Floor\nWashington, DC 20590\nDear Mr. Kelley,\nI am requesting clarification and a formal interpretation on 49 CFR 172.101(c)(2). The rule states:\nThe word “or” in italics indicates that there is a choice of terms in the sequence that may\nalternately be used as the proper shipping name or as part of the proper shipping name, as\nappropriate. For example, for the hazardous materials description “Carbon dioxide, solid or Dry\nice” either “Carbon dioxide, solid” or “Dry ice” may be used as the proper shipping name; and for\nthe hazardous materials description “Articles, pressurized pneumatic or hydraulic,” either\n“Articles, pressurized pneumatic” or “Articles, pressurized hydraulic” may be used as the proper\nshipping name.\nDoes the use of or in this rule prohibit the use of both proper shipping names together for one material?\nFor instance, the proper shipping name for UN 1219 is Isopropanol or Isopropyl alcohol. Is it appropriate\nfor this material to be listed as any of the following?\nUN 1219, Isopropanol (Isopropyl alcohol), 3, PG II, ERG: 129\nUN 1219, Isopropyl alcohol (Isopropanol), 3, PG II, ERG: 129\nMust a shipper use only one or the other proper shipping name, or can both names be used as shown?\nThank you for your attention and I look forward to your response.\nJoe Strelow\nOperations Manager\nRinchem Company, Inc\n917 Lone Oak Rd, Ste 100\nEagan, MN 55121","truncated":false,"body_characters":3656}
