Your letter was\nforwarded to the Office of Hazardous Materials Standards, Pipeline and Hazardous\nMaterials Safety Administration, for reply. This agency is responsible for promulgating the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180), which regulate the\ncommercial transportation of hazardous materials in the United States.\nThe loading and unloading requirements for explosives in a motor vehicle are prescribed in\n§§ 177.834 and 177.835 of the HMR. They require extreme care to be taken in loading,\nunloading, securing, and handling packages containing explosives so they are not exposed to\nany impact, projection, source of ignition, or damage that could cause these materials to\nreact. Section § 177.835(f) also requires motor vehicles transporting a Division 1.1, 1.2, or\n1.3 material to have floors that are tight (e.g., constructed closely so there are few or no\nintervening spaces). This section also requires the vehicle's interior cargo space be in good\ncondition so there will be no likelihood the packages will be damaged by exposed bolts,\nis in contact with the load must be lined with either non-metallic material or non-ferrous\nnuts, broken side panels, floor boards or similar projections. Any portion of the interior that\nmetals. Exceptions from lining the interior are provided for truck load shipments loaded by\nthe U.S. Department's of the Army, Navy, or Air Force provided the Class 1 (explosive)\nmaterials are not likely to leak dust, powder, or vapor that may cause an explosion.
