Sketch 1, Bureau of Explosives Pamphlet No. 6.) (7) Drums must be loaded not more than one tier (layer) high and with filling holes up. They must be loaded as closely together as possible both crosswise and lengthwise and so blocked and braced as to maintain their relative positions during transit. (8) Drums with filling holes in heads must be loaded on their bottoms. They may be loaded in rows, lengthwise of the car and any space between the sides of car and the nearest row of drums must be "filled in" with wooden boards or lumber nailed to sides of car sufficient in length and width to contact both hoops of drums, or, drums may be loaded across car in staggered stacks of which the number of drums in alternate stacks is reduced by one drum. All drums in stacks following the first stack loaded in end of car must be placed tightly into the angle of space formed by the sidewalls of the drum in the preceding stack. Any space between the sides of car and the drums in stacks having the greater number of drums, must be "filled in" with wooden boards or lumber nailed to sides of car sufficient in length and width to contact both hoops of drums. (9) Drums with filling holes in sides must be loaded on their sides with filling holes up. They must be loaded lengthwise of the car in rows and any space between sides of car and the nearest row of drums must be "filled in" with wooden boards or lumber nailed to sides of car sufficient in length and width to contact both hoops of drums. (10) Drums must be loaded in box car from ends of car toward space between car doors, and there braced by center gates and wedges. (See Sketch 1, Bureau of Explosives Pamphlet No. 6.) (11) Doorways of box cars must be protected by one of the methods prescribed in Sketch 1, Bureau of Explosives Pamphlet No. 6A. (12) Tanks must be securely mounted on cars especially provided for them or on gondola cars prepared with substantial wooden frames and blocks. (13) Bombs, projectiles, and cannon ammunition must be loaded, blocked and braced as shown in Bureau of Explosives Pamphlet 6A. When shipments are loaded in gondola cars they must be securely blocked and braced and not loaded higher than the sides of the car. (m) Material marked as or known to be poison (class A or B) must not be transported in the same car with material which is marked as or known to be foodstuffs, feeds, or any other edible material intended for consumption by humans or animals.

(a) Truck bodies or trailers containing explosives, class B, explosives, class C, or hazardous materials as provided in Parts 170-189 of this chapter must be of such design and so loaded that they will not rupture or become seriously damaged under conditions normally incident to transportation and must be so secured on the flat car that they cannot permanently change position during transit. Packages of explosives and hazardous materials contained therein must be loaded and braced as provided by §§ 174.529, 174.530, and 174.532. Placards must be applied when prescribed by §§ 174.541 and 174.542. (b) Truck bodies or trailers equipped with automatic heating or refrigerating equipment employing any fuel or article classed as a hazardous material in Parts 170-189 of this chapter may be loaded and transported on flat cars if such equipment is of a type approved by the Bureau of Explosives. They must be so braced and stayed on the flat car that they cannot permanently change position during transit. (c) Cargo tanks containing hazardous materials may not be transported in trailer-on-flat-car service except under conditions approved by the Federal Railroad Administrator.
