(2) Each conveyance must be under exclusive use, except when only transporting SCO–I on which the contamination on the accessible and the inaccessible surfaces is not greater than 4.0 Bq/cm
(3) For SCO–I where it is reasonable to suspect that non-fixed contamination may exist on inaccessible surfaces
(4) The highway or rail conveyance must be placarded in accordance with subpart F of part 172 of this subchapter.
