§ 75.655 Protection of packages.

(a) In handling packages containing explosives or other dangerous articles, care must be taken to prevent them from falling or from being broken. They must not be thrown, dropped, or rolled. Packages bearing the marking "This Side Up" or "This End Up" as required by Part 73 of this chapter must be so handled and loaded.

(b) Packages protected by labels must be so loaded that they cannot fall to the car floor and in such manner that other freight cannot fall onto or slide against them.

(c) Unless sealed cars are equipped with a suitable guard or screen to prevent the lading coming in contact with hot steam pipes, or heat exits used in electrically-heated equipment, packages containing explosives or other dangerous articles must not be transported in them.

(d) Shipments of explosives or other dangerous articles, except poisons and nonflammable compressed gases, when transported in passenger carrying trains, should be loaded in the car occupied by an express employee or in connecting cars to which an express employee has access through end doors, and in a place that will permit their ready removal in case of fire. They must not be loaded in cars or stored in stations near steam pipes or other sources of heat. Explosives, flammable liquids (red label), and flammable compressed gases (red gas label) must not be loaded, transported, or stored in cars or stations equipped with lighted heaters or where open-flame lights or stoves or electric devices having exposed heating coils are used. No placards are required on such cars when occupied by an express employee. Shipments bearing poison label, when practicable, should be loaded in sealed cars; when loaded in cars occupied by messenger, care should be taken to prevent any contents sifting or leaking from containers.

(e) When an express or baggage car containing any package requiring a label prescribed by Part 73 of this chapter is not occupied by an express employee, or is not a connecting car to which an express employee has access through an end door, and the car is handled in a passenger, mixed, or freight train, the proper placards must be attached thereto as required by Part 74 of this chapter for the transportation of such articles by rail freight.

(f) Packages containing dangerous articles, as defined by Part 73 of this chapter, that are loaded in sealed cars for express movement from the point of origin, must be loaded in a place that will permit of their ready removal in case of fire, wreck, or unloading, and near the car door, if possible.

(g) Not to exceed 10 gas identification sets may be transported in any car at any time.

(i) Unless they are leaking, or in a manifestly insecure condition, packages of dangerous articles other than explosives in transit must be forwarded to destination and report made of any violation observed. Leaking packages must be reconditioned or repaired promptly and forwarded to destination.

(j) A container of radioactive material bearing red label must not be placed in cars, depots 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 (2) of this paragraph by adding the number of units shown on labels on the containers.

(1) In a combination car carrying passengers and/or express shipments, a container of radioactive material must not be placed closer than 3 feet to the dividing partition. For more than one such container the distance must be computed by method described in subparagraph (2) of this paragraph.

(2) A container of radioactive material, red label, must not be placed closer than 15 feet to any package containing

NOTE 1: The distance in the table must be measured from the nearest point of the radioactive container or containers.

(7) In case of fire, wreck, breakage or unusual delay involving any shipment of radioactive material, the package or material should be segregated as far as possible from human contact. The shipper and the Bureau of Explosives should be immediately notified. In case of breakage of a package containing radioactive material and when it appears likely that the inside container may have been damaged, great care must be exercised to prevent contact with, inhalation, or any other means of the radioactive material entering the body. Cars, buildings, areas, or equipment in which class D poisons

have been spilled must not be again placed in service or occupied until decontaminated by qualified persons.

NOTE 1: Except for subparagraph (7), the requirements of this paragraph shall not apply to magnesium-thorium alloy materials or uranium, depleted or normal, described in § 73.392 (e) and (f) of this chapter.
