No.: 07-0195\nDear Mr. Pendergrast:\nThis is in response to your October 10, 2007, letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 17 1 - 180) applicable to vessel stowage.\nSpecifically, you request clarification of 8 176.83 for the segregation of incompatible\ncontainers on board container ships.\nIn your letter, you describe a scenario in which one container is stowed on deck and another\ncontainer is stowed below deck in a closed versus closed situation and the incompatible\ncontainers are required to be segregated longitudinally by an intervening complete\ncompartment or hold. It is your understanding that horizontal segregation is not required\nprovided the containers are not stowed in the same vertical line and separated by a fire and\nliquid resistant bulkhead.\nYour understanding is correct. The fore and aft segregation requirements need only be\napplied to incompatible containers when they are both on deck or when they are both under\ndeck, unless otherwise stated.\nI hope this information is helpful. Please contact us if you require additional assistance.\nSincerely,\n/ Chief, Standards Development\nOffice of Hazardous Materials Standards\n\n<<>>\n\nL r~q Page I of I\nDrakeford, Carolyn From: INFOCNTR \nSent: Thursday, October 11,2007 10:02 AM\nTo: Drakeford, Carolyn \nSubject: FW: Formal lntrepretation Letter Request\nAttachments: Formal-Interpretation-Request-Leter.doc\nCarolyn,\nCould you process this as a formal request for interpretation?

ICODES is an agent-based software package\nand one of the agents is the Hazardous Agent, which uses the IMDG and the 49CW to\ndetermine proper segregation of hazardous cargo items. There are several segregation\nrequirements that we are requesting formal interpretations.\nFor Level 4 segregation of containers, closed versus closed, the requirements are noted\nbelow.\nTO\" view d4Ek --\nfop vlew hold\nIn the case in which one container is stowed on deck and another container is below deck,\nthe ICODES system returns a violation that notes that the vertical stowage of these items\nis prohibited, but also requires a minimum horizontal segregation of 24 meters. To me, it\nseems as if the items can not be in the same vertical line but do not need any other\nsegregation.\nThis interpretation is based on an example of level 3 segregation of closed containers,\nwhere in items can be in the same vertical line if they are separated by a fire and liquid\nresistant bulkhead. If the two items are separated by a fire and liquid resistant bulkhead\nwith one on deck and one under deck, additional requirements would not be required in\nthe fore and aft or athwartship direction (1.e.: one container space or one bulkhead).\n\n<<>>\n\n-\n\"SEPARATED 8 Y A COMPLETE COMPARTMENT OR HOLD FROM\" .3\nCLOSEDVERSUSCLOSED\nHORIZONTAL\nOR\n-\"-\nCLOSED VERSUS OPEN\nON DECK UNDER DECK\nVERTICAL i i\n-\n:\nFORE AND AFT\ni ~ r m conlamer SCi:tGc j , . \",.\nATHWARTSHIPS\none ocl~k~c-ad 1 \" .... ... i ....... ... .......... .......... .......... .. .................... .........\nNCCr in the same rotica .re f\nTWO cnn!aine~ sl'tncos 1 On!.; b ~ % l t a ~ : ? ,~r~less su;ragatad i?y ;L oe:$ ;\n... \". .\"\",---,\".\",--,...- .,*, ,*.-\"\"\" ..,.... -,..* .,.,.. -\n....-.--, - .-.--\nLongltudinaily Athwartships\nc Aft Fwd. 4 Port sib,\nDeck\nHold\nTap view deck\n1-\nIS\"\ni:\n3 - Situations closed versos closed and closed versus open\n)Vole: Ail bulktleods turd ducks st.lou1.j be resistant to fire itrrcf liquids,\nI can demonstrate these situations on our ICODES system via a WebEx, if necessary.\nI appreciate your attention to this matter.\nRegards,\nBoone Pendergrast\nICODES Customer Support\nCDM Technologies, Inc.\n805-541 -3750 x262 (office)\n805-550-0244 (cell)\n805-541 -8296 (fax)\nboone@cdmtech.com","truncated":false,"body_characters":5150}
