You also provide photographs illustrating the\nplacement of your markings on an MC 331 cargo tank motor vehicle.\nThe answer is yes. In accordance with § 178.337-9(c), each cargo tank inlet and outlet, with the\nexception of gauging devices, thermometer wells, and pressure relief devices, must be marked\n\"liquid\" or \"vapor\" to designate whether it communicates with liquid or vapor when the cargo\ntank is filled to the maximum permitted filling density. Provided the marking is readily visible,\nlegible, durable to withstand transport conditions, and clearly associated with the corresponding\ninlet/outlet, the marking would satisfy the requirements of the HMR.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nShane Kelley\nDirector\nStandards and Rulemaking Division\n\n<<<PAGE 2>>>\n\nAndrews\n8/78.337-9c\nDodd, Alice (PHMSA)\nPackagung specs\nFrom:\n170020\nSent:\nINFOCNTR (PHMSA)\nTo:\nTuesday, February 14, 2017 5:09 PM\nSubject:\nHazmat Interps\nAttachments:\nFW: Clarification of Ref.
