No. 03-0114\nDupont Global Services Business\n1007 Market Street, Room D-5100\nWilmington, DE 19898\nDear Mr. Martin:\nThis responds to your November 18, 2002 letter requesting clarification on the proper shipping name to\nbe marked on your tank cars under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-\n180). We apologize for the delay in responding and hope it has not caused you any inconvenience.\nSpecifically, you ask if it is permissible to mark the proper shipping name, \"Sulfuric Acid\" for both your\n\"Sulfuric acid, UN 1830\" and \"Sulfuric acid, spent, UN 1832\" materials carried in the same fleet of rail\ntank cars.\nAccording to your letter, you supply your customer with tank cars of \"Sulfuric acid, UN1830\". The\ncustomer then recovers and returns to you \"Sulfuric acid, spent, UN 1832\". In order to avoid changing\nthe marking every time the tank car switches from \"Sulfuric acid, UN 1830\" to \"Sulfuric acid, spent,\nUN 1832\" and back again, you want to use \"Sulfuric acid\" to describe both materials. It is your\nunderstanding that it is permissible to use the proper shipping name, \"Sulfuric acid\" for both materials\nunder the HMR.\nBased on the information provided in your letter, it is the opinion of this Office that use of the words\n\"Sulfuric acid\" marked on the tank car to describe both materials is permissible. However, the proper\nUN identification number must be displayed on the tank car and the shipping papers must show the\nproper shipping description and UN identification number for the material being shipped.\nI hope this answers your inquiry.\nSincerely,\nDelmer F.

McGuire\nDear Dr. McGuire:\nWe currently have a customer that we supply with tank cars of Sulfuric Acid, UN1830.\nThe customer then recovers and returns to us Sulfuric Acld, Spent, UN1832. We use the\nsame fleet of tank cars and are trying to determine the correct markings for the proper\nshipping names.\nEven though 172.330(a)(1)(il) does not require that we mark the tank cars with the Proper\nShipping Name for either of these products, our policy is to mark all our tank cars with\neither the Proper Shipping Name or the product name. So we have chosen \"Sulfuric\nAcid\" and \"Sulturic Acid, Spent\" as the correct markings.\nfrom UN1830 to UN1832 and back agaln (which Is frequent), we are proposing to mark\nBut in order to avoid changing the product marking every time the tank cars switches\nthe tank cars \"Sulfuric Acid\" for both products. Our concern is that when a car contains\namong regulators and inspectors, and would like your opinion as to whether or not this\nSulfuric Acid, Spent, UN1832, yet is marked \"Sulfuric Acld\" It may cause some confusion\nproposal is acceptable under the current regulations.\nESt Pot da Numers and Company\nPrinted on Rusyclul Papar\nG-798\n\n<<<PAGE 3>>>\n\n•.\nDä-Ngä\n04/30/03\n15:30 • :03/03 NO:334\n-2.\nOur Interpretation of 171.2(f)(2) is that we cannot mark a rail car containing Sulfuric Acid\nmarked \"Sulfuric Acld\". The reasoning is that while spent sulfuric acid is always also\nwith \"Sulfuric Acid, Spent\", but a rail car containing Sulfuric Acid, Spent could be\nsulturic acid (at loast from a chemical composition porspective), the reverse is not true.\nYour prompt attention Is greatly appreciated.\nSincerely,\nRuasbia\n•\nHazardous Materials Distribution Consultant\nRandolph Martin\n1007 Market Street, Room D-5100\nDuPont Global Services Business\nWilmington, DE 19898\nPhone: (302) 773-4248\nFAX: (302) 773-5011","truncated":false,"body_characters":4059}
