No. 05-0275\nHorizon Lines\nBlount Island\n5800-1 William Mills Street\nJacksonville, Florida 32226\nDear Mr. Bartley:\nThis is in response to your October 24, 2005 letter requesting clarification of the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask\nfor clarification of § 176.400(c), which requires Division 1.5 and Class 5 (oxidizers and\norganic peroxides) materials to be stowed in a separate compartment or hold from any\nreadily combustible material during transportation by vessel. You ask if that section\napplies to materials transported in a closed transport unit (CTU), as break-bulk cargo, or\nThe stowage restriction in § 176.400(c) applies to any Division 1.5 or Class 5 material,\nregardless of whether it is transported inside a CTU or as break-bulk cargo. Thus, under\nthe HMR, any Division 1.5 or Class 5 material transported by vessel must be stowed in a\nseparate compartment or cargo hold from any readily combustible material. You are\ncorrect that paragraph 7.1.11.1 of the International Maritime Dangerous Goods Code\n(IMDG Code) includes an exception from this stowage restriction for Division 5.1\nmaterials in CTUs. Note, however, that in accordance with paragraph 7.1.11.4,\nprecautions must be taken to avoid the penetration of oxidizing substances into other\ncargo spaces, bilges, or other areas that may contain combustible material. It is the\nopinion of this Office and the United States Coast Guard that the exception in paragraph\n7.1.11.1 of the IMDG Code would apply to Division 5.1 materials in a CTU stowed in the\nsame compartment or cargo hold as combustible materials in a CTU; however, under the\nIMDG Code Division 5.1 materials, whether in a CTU or transported as break-bulk\ncargo, may not be stowed in the same compartment or cargo hold with break-bulk\n176.83 (f)\n176:400\n050275\n\n<<<PAGE 2>>>\n\ncombustible material. Further, Division 1.5 materials are generally required to be stowed\nin a separate compartment or hold from other cargo that is readily combustible in\naccordance with paragraph 7.1.7.4.1.1.\nI hope this information is helpful. Please contact us if you require additional assistance.\nSincerely\n\n<<<PAGE 3>>>\n\nZHONZON\nFichenlaub\nOctober 24, 2005\n$176.83(f)\n§116.400\nMr. Ed Mazzullo\nDirector Office of Hazardous Materials\nVessel\nHazardous Materials Standards\nUSDOT / PRMSA / DHM10\n05-0275\n400 7 Street S.W.\nWashington, DC 20590\nRe: 49CFR176.400( c) Detailed Requirements for class 4, Class 5 and division 1.5 materials\nDear Mr. Mazzullo,\nWe, Horizon Lines, LLC, are a domestic containerized ocean transportation company. I am\n49CFR176.400(c)\" which states:\nseeking understanding on the applicability to container shipments of the statement in\n\"No division 1.5 or class 5 )oxidizers and organic peroxides) material being transported by\nvessel may be stowed in the same hold or compartment with any readily combustible material\nsuch as a combustible, a textile product, or with a finely divided substance, such as a organic\npowder.\"\nMy question is does this statement apply to containerized shipments?\nContainer stowage and segregation is generally done in conjunction with the tables of 175.83(b)\nand 176.83(f) combined with the considerations of the detailed stowage requirements. In the\ncase of a class 5 and a class 8, the segregation is listed as \"Separated from\" which allows for a\nminimum of 20 feet distance between the two incompatible classes but there is no indication that\nthe cargo must be stowed in separate hatches. It seems that the statement in 49CFR176.400(c)\nwas targeted towards break bulk cargo rather than containerized cargo.\nThe parallel detailed stowage reference in the International Maritime Dangerous Goods Code in\nsection 7.1.11.1 - 4 specifically excludes container shipment from the restriction. Section\n7.1.11.1 of the IMDG code states:\n\"Except for cargo spaces for the stowage of cargo transport units, cargo spaces shall be\ncleaned before oxidizing substances are loaded into them. Attention shall be paid to the removal\nof all combustible materials which are not necessary for the stowage of such cargoes.\"\nIn discussing this matter with the U.S. Coast Guard, they seem to agree that this section does not\napply to containers.\n1\nHorizon Lines • Blount Island • 5800-1 William Mills Street • Jacksonville.
