Dugan\nReference No.: 04-0258\nSafety & Occupational Health Specialist\nMilitary Surface Deployment and Distribution Command\n661 Sheppard Place\nFort Eustis, VA 23604-1644\nDear Mr. Dugan:\nThis responds to your letter requesting clarification of the requirements for segregation of\nexplosives under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).\nSpecifically, you ask whether transportation of Division 1.4S detonators in a dromedary box on a\nmotor vehicle that is also transporting a trailer loaded with Division 1.1, 1.2, and 1.3 materials\nsatisfies the segregation requirements for motor carrier transportation.\nThe answer is no. Section 177.835(g) prohibits the transportation of detonators on the same\nmotor vehicle with any Division 1.1, 1.2, or 1.3 material (except other detonators, detonator\nassemblies, or boosters with detonators), detonating cord Division 1.4 material, or Division 1.5\nmaterial unless the conditions specified in § 177.835(g)(1), (2), or (3) are met. A \"motor\nvehicle\" is defined as any number of transport vehicles powered by the same motor or engine\n(except vehicles that travel by rail or trolley). A \"transport vehicle\" is a cargo-carrying vehicle,\nsuch as an automobile, van, tractor, truck, or rail car used for the transportation of cargo by any\nmode. Each cargo-carrying body (such as a trailer or dromedary box) is a separate transport\nvehicle.\nYou suggest that the term \"motor vehicle\" as used in § 177.835(g) should be interpreted to mean\n\"transport vehicle\" to permit Division 1.4S detonators to be transported on the same motor\nvehicle with Division 1.1, 1.2, and 1.3 material. We do not agree. The clear intent of\n§ 177.835(g) is to prohibit such transportation except under the conditions specified. You may\npetition for a regulatory change under the procedures established in 49 CFR 106.95 applicable to\npetitions for rulemaking.\nI hope this satisfies your request.\nSincerely,\nHitle z Makel\nHattie L.

Mazzullo\nExplosive\nDirector, DHM-10\nOffice of Hazardous Materials Standards\n04-0258\nResearch and Special Programs Administration\n400 Seventh Street, SW\nU.S. Department of Transportation\nWashington, DC 20590\nDear Sir:\nDepartment of Defense hereby requests interpretation of hazardous materials regulations as outlined below. The\nIn accordance with the provisions of Title 49, Code of Federal Regulations (CFR), Section 105.20, the\nfollowing file number has been assigned:\nFile Number: 213-04 (1108)\nProponent: Department of Defense\nRequest Officlal Interpretation of standards 49 CFR 177.835(g)\nassemblies, and boosters with detonators. The Class 1 Compatibility Table in Para 177.848 denotes footnote 4 under\nRequest interpretation of Para 177.835(g) as it pertains to Hazard Class/Div 1.4S detonators, detonator\nthe group \"S\" column. In explaining foomote 4, para 177.848(g) (3)(iv) directs you back to 177.835(g), which states\nthat detonators may not be transported on the same motor vehicle with any Division 1.1, 1.2, or 1.3 material (except\nother detonators etc). DOD believes that the term \"motor vehicle\" above should actually be \"transport vehicle\".\nThis would allow having 1.4S detonators in a dromedary box attached to a tractor which was also pulling a trailer\n(the second transport vehicle loaded with other 1.1, 1..2, 1.3 materials.\nboosters with detonators in the first place. The hazardous nature of 1.4S material, by definition, is very minimal.\nA further question we have is why should this restriction affect 1.4S detonators, detonator assemblies, and\nOther hazardous material regulations such as International Maritime Dangerous Goods Code or AFMAN 24-204(I),\nPreparing Hazardous Materials for Military Air Shipments, do not make a distinotion, for compatibility purposes,\nsmall arms ammunition. Could the verbiage in Para 177.835(g) be a carryover from the days when most detonators\nbetween 1.49 detonators, detonator assemblies, and boosters with detonators and any other kinds of 1.4S, such as\nthat marter) simply to carry 1.4S detonators, detonator assemblies, or boosters with detonators; while at the same\nwere 1.1B items? We see no reason for requiring a separate motor vehicle (or even a separate transport vehicle for\ntime 1.45 small arms ammunition can be loaded together with most 1.1, 1.2, 1.3 material. We believe 1.45\ndetonators, detonator assemblies, and boosters with detonators should be treated as they are in these other\nregulations; the same as any other 1,4S item.\nSafety Staff:, Military Surface Deployment and Distribution Command, 661 Sheppard Place, Fort Eustis, VA 23604-\nThis request is submitted by Mr. Joseph P.
