Specifically you ask whether\nDivision 1.1 or 1.2 explosives may be carried on any vehicle or combination of vehicles with\nany Division 2.3 (poison gas) or 6.1 (poisonous) materials under the Hazardous Materials\nRegulations (HMR; 49 CFR parts 171-180).\nThe answer is no. Section 177.835(c) states that Division 1.1 or 1.2 materials may not be\nloaded into or carried on any vehicle or a combination of vehicles if the other vehicle in the\ncombination contains \"Division 2.3 (poisonous gas) or Division 6.1 (poisonous ) materials.\"\nThe phrase \"Division 2.3 (poisonous gas) or Division 6.1 (poisonous ) materials\" includes all\nDivision 2.3 materials, regardless of hazard zone, and all Division 6.1 material, regardless of\nthe physical state or packing group of the material.\nI hope this satisfies your request.\nSincerely,\nDelmer F. Billings\nChief, Standards Development\nOffice of Hazardous Materials Standards\n:\n\n<<<PAGE 3>>>\n\nKent F.

(E.g. same trailer, same truck).\nI understand from your response that 49 CFR 177.835, does in fact prohibit the loading of Division\n1.1 or Division 1.2 explosives with any Division 2.3 (poison gas) or Division 6.1 (poisonous) material, in\nthe same transport vehicle (e.g. same trailer, same truck), as well in a combination of vehicles.\n•\nI make this request for clarification as co-workers have stated that 49 CFR 177.835©, applies only to\ncarried on any vehicle or a combination of vehicle if the other vehicle in the combination contains any\nvehicles in combination reasoning that, \"Division 1.1 or 1.2 materials may not be loaded into or\nDivision 2.3 (Poisson gas) or Division 6.1 (poisonous) materials.\nCo-workers position is that the regulation refers to \" the other vehicle\" and is therefore not applicable\nto loading Division 1.1 or 1.2 explosives with Division 2.3 (poison gas) or Division 6.1 (poisonous)\nmaterials on the same transport vehicle.\nIt would seem reasonable to assume that, if you cannot load these items in combination, you cannot\nload them together. However, I await your clarification.\n--\n\n<<<PAGE 4>>>\n\n• -\nKent F.
