No. 03-0217\nSouthern International, Incorporated\n4200 Perimeter Center Drive, Suite 205\nOklahoma City, OK 73112-2391\nDear Mr. Brittenham:\nThis responds to your August 18, 2003, letter requesting clarification concerning requirements for\nmanholes, latches, and ladders on Specification DOT 406, DOT 407 and DOT 412 cargo tank motor\nvehicles that transport petroleum crude oil under the Hazardous Materials Regulations (HIMR;49 CFR\nParts 171-180). Your questions are paraphrased ans answered below:\nQ1. What DOT regulations apply to cargo tank hatch assemblies for DOT specification 406, 407, and\n412 cargo tank motor vehicles?\nAl. Section 178.345-5 of the HMR specifies the requirements for manhole assemblies on DOT 406,\n407, and 412 cargo tank motor vehicles. The term \"hatch assembly\" and \"manhole assembly\" are\nsynonymous for regulatory purposes. Generally, a manhole assembly mut be structurally capable of\nwithstanding without leakage a static internal fluid pressure of at least 36 psig or cargo tank test\npressure, whichever is greater.\nQ2. Are there any DOT regulations that pertain to ladders on cargo tank motor vehicles?\nAZ. Under the HMR, ladders attached to cargo tank motor vehicles are regulated as appurtenances.\nAn appurtenance includes any attachment to a cargo tank that has no lading retention or containment\nfunction and provides no structural support to the cargo tank, as defined in § 178.320 of the HMR.\nDesign, construction, and installation requirements for such appurtenances are provided in § 178,345-\n3(f) for DOT 406, 407, and 412 cargo tank motor vehicles.\nI hope this answers your inquiry.\nSincerely,\nSusan\nSenior Transportation Regulations Specialist\nOffice of Hazardous Materials Standards\n178.345-5\n030217\n\n<<<PAGE 2>>>\n\nSouthern International, Incorporated\nOklahoma City, OK 73112-2391\n4200 Perimeter Center Drive, Suite 205\nTelephone: (405) 943-5288\nUSA\n• Telefax: (405) 947-4149\nE-Mail: Sll@icnet.net\nBoothe\nAugust 18, 2003\n5178.345-5\nCargo lank\nMr. Edward T.
