against other lading falling onto or against them; and adequate means shall be provided in all cases for the protection and insulation of battery terminals against short circuits. (d) Tanks complying with ICC-106A (§ 178.275 of this chapter) specification used for the transportation of corrosive liquids as authorized in § 173.264(b) (6) of this chapter may be transported in or on motor vehicles and in the manner authorized in § 177.840 (c), provided adequate facilities are present for handling tanks where transfer in transit is necessary. Tanks must be securely chocked or clamped thereon to prevent shifting. § 177.840 Compressed gases. (See also § 177.834 (a) to (k).) (a) Floors or platforms essentially flat. Cylinders containing compressed gases shall not be loaded onto any part of the floor or platform of any motor vehicle which is not essentially flat; cylinders containing compressed gases may be loaded onto any motor vehicle not having a floor or platform only if such motor vehicle be equipped with suitable racks having adequate means for securing such cylinders in place therein. Nothing contained in this section shall be so construed as to prohibit the loading of such cylinders on any motor vehicle having a floor or platform and racks as hereinbefore described. (1) Cylinders. Cylinders containing compressed gases shall be securely lashed in an upright position so as to prevent their overturning; or loaded into racks securely attached to the motor vehicle; or packed in boxes or crates of such dimensions as to prevent their overturning; or loaded in a horizontal position. Spec. ICC-4L cylinders must be loaded in an upright position and be securely braced. (b) Portable tank containers containing compressed gases shall be loaded on motor vehicles only as follows: (1) Onto a flat floor or platform of a motor vehicle. (2) Onto a suitable frame of a motor vehicle. (3) In either such case, such containers shall be safely and securely blocked or held down to prevent movement relative to each other or to the supporting structure when in transit, particularly during sudden starts and stops and changes of direction of the vehicle. (4) Requirements of subparagraphs (1) and (2) of this paragraph shall not be construed as prohibiting stacking of containers, provided the provisions of subparagraph (3) of this paragraph are fully complied with. (c) Tanks complying with ICC-106A or ICC-110A (§ 178.275, 178.276, 178.278, 178.293 or 178.295 of this chapter) specifications used for the transportation of compressed gases as authorized in § 173.314(a), Note 12 of this chapter, may be transported in a combination of vehicles as follows: (1) in or on a truck and in or on one semi-trailer or one full trailer attached thereto, with no other trailer included in the combination, (2) in or on a semi-trailer attached to a trucktractor and in or on a full trailer attached thereto, with not more than one semitrailer and one full trailer in the combination, provided adequate facilities are present for handling tanks where transfer in transit is necessary. Tanks must be securely chocked or clamped thereon to prevent shifting. As used herein a full trailer includes a semi-trailer equipped with a front axle dolly. Each full trailer used in any of the above combinations, in or on any vehicle of which combination any such tank is transported, must have a wheel base of at least 184 inches. See § 174.560 of this chapter for railfreight-motor vehicle shipments. (d) Engine to be stopped in tank motor vehicles, except for transfer pump. No flammable compressed gas shall be loaded into or on or unloaded from any tank motor vehicle with the engine running unless the engine is used for the operation of the transfer pump of the vehicle. Unless the delivery hose is equipped with a shut-off valve at its discharge end, the engine of the motor vehicle shall be stopped at the finish of such loading or unloading operation while the filling or discharge connections are disconnected. (e) Chlorine cargo tanks shall be shipped only when equipped (1) with a gas mask of a type approved by the U.S. Bureau of Mines for chlorine service; (2) with an emergency kit for controlling leaks in fittings on the dome cover plate. (f) No chlorine tank motor vehicle used for transportation of chlorine shall be moved, coupled or uncoupled, when any loading or unloading connections are attached to the vehicle, nor shall any semi-trailer or trailer be left without the power unit unless such semitrailer or trailer be checked or equivalent means be provided to prevent motion. (a) Arsenical compounds in bulk. Care shall be exercised in the loading and unloading of "arsenical dust", "arsenic trioxide", and "sodium arsenate", allowable to be loaded into siftproof, steel hopper-type or dump-type motor-vehicle bodies equipped with water-proof, dust-proof covers well secured in place on all openings, to accomplish such loading with the minimum spread of such compounds into the atmosphere by all means that are practicable; and no such loading or unloading shall be done near or adjacent to any place where there are or are likely to be, during the loading or unloading process assemblages of persons other than those engaged in the loading or unloading process, or upon any public highway or in any public place. (b) No class A or class C poisons in cargo tanks. No dangerous poison, class A, or any tear gas or irritating substance, class C, may be loaded into or transported in any cargo tank. (c) Class A or class C poisons. It shall not be permissible to transport class A or class C poisons if there be any interconnecting means of any character between the containers. NOTE 1: Tanks complying with ICC-106A (§ 178.275 or 178.276 of this chapter) specification containing class A or B poisons as authorized in §§ 173.333 (a)(2), 173.336(a)(3), 173.338 (a) (3), 173.353 (a) (5) and 173.357 (b) (4) of this chapter may be transported in or on motor vehicles and in the manner authorized in § 177.840 (c), provided adequate facilities are present for handling tanks where transfer in transit is necessary. Tanks must be securely chocked or clamped thereon to prevent shifting. (d) Radioactive material. A container of radioactive material, red label, must not be placed in vehicles, terminals, or other places closer than 3 feet to an area which may be continuously occupied by passengers, employees, or shipments of animals. When more than one such container is present, the distance from occupied areas must be computed from the table in subparagraph (1) of this paragraph by adding the number of units shown on labels on the containers. (1) A container of radioactive material, red label, must not be placed closer than 15 feet to any package containing undeveloped film. If more than one such container is present the distance must be computed from the table in this subparagraph by adding the num NOTE 1: The distance in the table must be measured from the nearest point of the radioactive container or containers. (2) Shipments of radioactive materials as provided for in § 173.393 of this chapter shall be loaded and stored such that the number of radiation units (§ 173.391(b) of this chapter) in any car, vehicle or storage location does not exceed 40, as determined by totaling the number of radiation units shown on the individual labels on the packages. The provisions of this "40-unit rule" do not apply to sole-use shipments described in § 173.392 or § 173.393 of this chapter. (3) All containers of radioactive material, red label, must be carried by the handles when handles are provided. (4) Shipments of radioactive materials of low specific activity, loaded in accordance with § 173.392 (c) of this chapter, must be loaded so as to avoid spillage and scattering of loose material. (5) Packages must be so blocked and braced that they cannot change position during conditions normally incident to transportation. NOTE 1: The requirements of this paragraph shall not apply to magnesium-thorium alloy materials or uranium, normal or depleted, described in § 173.392 (e) and (f) of this chapter. The location of bundles, boxes, barrels, or crates of such material from packages of undeveloped film must be as stated on the label (see § 173.414(e) of this chapter). (e) Poisonous liquids or solids, class B, must not be transported in the same vehicle with any foodstuffs, feeds, or any other material intended for consumption by humans or animals which are not packaged in air tight nonpermeable containers.
