No. 09-0104\nDear Mr. Alvarez:\nThis responds to your letter requesting clarification and guidance on the correct application of the\nstowage requirement \"shade from radiant heat\" in the context of containerized cargo on container ships.\nSpecifically, you expressed your understanding that a closed cargo transport unit does not need to be\nshaded by means of a structural erection or an awning in accordance with § 176.63(b) ofthe Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) and Appendix 1 to Chapter 7.1 ofthe\nInternational Maritime Dangerous Goods (lMDG) Code because the cargo transport unit itself provides\nshade for the packages or material contained therein.\nYour understanding is correct. Structural erections or awnings are not required to protect cargo transport\nunits from radiant heat when stowed on the weather deck of a container ship or any other ship type. The\nrequirements contained in §173 .63(b) ofthe HMR and paragraph 7.1.1.13 ofthe IMDG Code generally\napply to packages or articles stowed on the weather deck without any other means of protection from\nstrong sunlight. Nonetheless. due consideration should be given to the heat sensitivity ofthe contents\nwithin the cargo transport unit and, when necessary, stowage locations in the top tier or in outermost row\nofcontainers should be avoided.\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\nHattie L. Mitchell\nChief.

Mazzullo\nDirector, Office of Hazardous Materials Standards\nU.S. DOT/PHMSA (PHH-10)\n1200 New Jersey Avenue, SE East Building, 2nd Floor\nWashington, DC 20590\nDear Mr. Mazzullo,\nWe address this message to the PHMSA in order to clarify the term \"shade from radiant heat\" when applicable to\ncontainers transported on full container ships.\nIn our opinion, a closed container exceeds the minimum criteria, as follows:\nConcept: Shade from radiant heat\nType of ship: Full container vessel\nType of cargo: in containers\nThe IMDG Code defines \"shaded\" in the Appendix 1, Deck Stowage, item (2).\nThe minimum requirement is to cover the top of the package.\nOn these grounds any freight container meeting the \"Closed Container Transport Unit\" definition exceeds the\nminimum requirement, consequently any CCTU packed with packaged dangerous goods that need to be\n\"SHADED FROM RADIANT HEAT\" does not need any extra measure to meet the regulatory criteria.\nThis is applicable to any CCTU including insulated/double shell portable tanks.\nOn same grounds single shell/uninsulated portable tanks and open CTUs do require to have a container on top to\nmeet the requirement.\nThe CFR 49, in § 176.63 (b), last paragraph, reads \"the stowage must be protected from the direct rays of the sun\nby means of structural erections or awnings except that such protection is not required for shipment in portable\ntanks.\"\nAs the initial reference is made to the Table 172.101, we understood this sentence as associated to packages\nwhich leads us to the same interpretation done above for the IMDG Code, although there is no a picture to clarify\nthat the awning is only need on top and not on the sides. It also excludes the portable tanks.\nWe will appreciate to receive the PHMSA interpretation and guidance on the correct use of the term \"shade from\nradiant heat\" for containerized cargoes on full container ships.\nContact Information:\n5/412009\n\n<<<PAGE 3>>>\n\nPage 2 of2\nName: Hector Alvarez\nOrganization: Companla SudAmericana de Vapores\nStreet Address: Sotomayor 50\nCity: Valparaiso\nState: Country\n(International Only): Chile\nZip Code: 2362335\nE-mail Address:halvarez@csavgroup.com\nTelephone Number: +56-32-2203580\nFax Number: +56-32-2203938\nThan~ngyouinadvance\nHector Alvarez\nThe CSAV Group\nDangerous Goods & Documentation Department\nTel 56-32-220 3580 I Fax 56-32-220 3938\n5/4/2009","truncated":false,"body_characters":4805}
