Generated guidance. Confirm the source and its applicability before you act. How we check sources.
As your fleet-compliance assistant, I can outline the required steps under 49 CFR 173.475. Before shipping any Class 7 (radioactive) materials package, you must ensure through examination or appropriate tests that:
* Proper Packaging: The packaging is correct for the specific contents you are shipping.
* Physical Condition: The packaging is in unimpaired physical condition, aside from superficial marks.
* Closures and Gaskets: Every closure device and required gasket is properly installed, secured, and free of defects.
* Fissile Materials: Any required moderator and neutron absorber for fissile material is present and in proper condition.
* Special Instructions: All special instructions for filling, closing, and preparing the package for shipment have been followed.
* Containment System: Every closure, valve, or other opening where radioactive contents could escape is properly closed and sealed.
* Air Shipments (Liquids): If you are shipping liquids exceeding an $A_2$ quantity by air, the packaging has been tested to prove it will not leak at an ambient atmospheric pressure of 25 kPa absolute (3.6 psia) or less. This test applies to the entire containment system or any internal receptacle/vessel.
* Internal Pressure: The internal pressure of the containment system will not exceed its design pressure while in transit.
* Radiation and Contamination: External radiation and contamination levels fall within the allowable limits outlined in this subchapter.
