(a) Marking must be as prescribed in § 178.3.

(b) Marking on the outside of each package must be as follows: “DOT-6M Type B,” “Radioactive Materials,” or “Fissile Radioactive Materials,” as appropriate; and the gauge of metal of the outer drum in the thinnest part, rated capacity of the outer drum in gallons, and year of manufacture (for example, 18-30-69).
