Tallman\nManager\nEnvironmental Management and Controls, Inc.\n3106 South Faith Home Road\nTurlock, California 95380\nDear Mr. Tallman:\nThis is in response to your lefter of February 10, 1998, requesting clarification of the\nPrecedence of Hazard requirements in § 173.2a of the Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171-180). Your question is presented in the following scenario:\nA package contains a mixture of radioactive materials and flammable liquids.\nThe mixture can be named either \"Radioactive material, LSA II\" or\n\"Radioactive material, limited quantity\" and thus be reclassed as a flammable\nliquid due to the hierarchy of the precedence table. Does the shipper have the\nchoice to ship it as either of these classifications or is he bound by the HMR to\nuse a specific classification?\nIn a situation where a shipper has a mixture of radioactive materials and flammable liquids\nthat meet the detinition of a limited quantity, the shipper has the choice to either classify the\nmaterial as a limited quantity or to maintain the material's original classification. If the\nshipper chooses the proper shipping name \"Radioactive material, limited quantity\" as in the\nexample above, and that material meets the definition of more than one hazard class or\ndivision, it shall be classed in accordance with § 173.423.\nI hope this answers your inquiry. If you need additional assistance, do not hesitate to contact\nSincerely,\n•\nOffice of Hazardous Materials Standards\n\n<<<PAGE 2>>>\n\nENVIRONMENTAL MANAGEMENT AND CONTROLS, INC.\n3106 SOUTH FAITH HOME ROAD\nTURLOCK, CALIFORNIA 95380\ncontracto\nPHONE (209) 667-1102\nFAX (209) 667-1583\nM\ne: 173.2\n163\nFebruary 10, 1998\n7l:,90,\nEdward T. Mazzullo\nDirector, Office of Hazardous Material Standards\nUSDOT/RSPA DM-10\n400 7* Street SW\nWashington DC 20590-0001\nDear Mr. Mazzullo:\nI am requesting a written interpretation of the DOT regulations governing the\nclassification of packages with multiple hazards.\nAccording to 49CFR173.2(a), a package containing both radioactive materials and\nflammable liquids (such as liquid scintillation cocktails, a majority of which can be\nclassitied as either radioactive material, LSA II (173.403) or radioactive material, limited\nquantity (173.421))) would be classified IAW with the hierarchy contained within 173.2\n(a).\nNumber one in this hierarchy is radioactive material (except limited quantities) with\nflammable liquids appearing as number eight in the listing. In conversation with Todd at\nthe DOT information center, it was stated that if the radioactive material would qualify as\nradioactive limited quantity, regardless of the fact it would also qualify as LSA, the\nregulations require that the flammable liquids classification take precedence.\nIn order to document that the transportation of this type of material as Radioactive\nMaterial, LSA, nos, UN2912 (flammables technical names) is inconsistent with the\nregulations, I am requesting this interpretation in writing\nThank you for your attention to this request.\nSincerely,\nOf Layman\nDan A.
