In case of obvious leakage, or if the inside container appears to have been damaged, the section (hold, deck area, or compartment) containing this cargo must be isolated as much as possible, and care should be taken to prevent radioactive material from entering the body through contact, inhalation, or ingestion. No person shall be allowed to handle the material or to remain in the Descriptive name of article Fissile radioactive materials. Radioactive devices. Radioactive materials, small quantities. Characteristic properties, cautions, markings required vicinity until qualified personnel are present to supervise. In any incident in which radioactive materials are involved in fires or are damaged, the shipper and the District Commander of the U.S. Coast Guard, or his authorized representative as prescribed by § 2.20-65 of this chapter, having supervision over the port or place where the vessel is located or bound, shall be notified immediately. (b) Holds and compartments used for the transport of low activity materials as full loads or in which leakage of radioactive materials has occurred because § 146.19-100 Table-Classification: Required conditions for transportation Fissile radioactive material has the additional property that it affords a possibility of a self-sustaining nuclear fission reaction including Pu238, Pu289, Pu241, U283, and U235, as described in §§146.19-1 and 146.19-12. Exempt materials are listed in §146.19-12(g). Do not stow with explosives, flammable gases, flammable liquids, flammable solids, oxidizing materials, corrosive liquids, cotton, foodstuffs, or mail. Do not stow near undeveloped photographic or radiographic Alms. (See 146.19-35.) Radioactive devices are manufactured articles such as instruments, clocks, electronic tubes or apparatus, or other similar devices having radioactive materials as a component part, meeting the requirements of § 146.19-14(b). Small quantities are radioactive materials as limited by, and meeting the conditions of, §146.19-14(a). Do not stow with explosives, flammable gases, flammable liquids, flammable solids, oxidizing materials, corrosive liquids, cotton, foodstuffs, or mail.
