each conveyance shall 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 10 times the applicable level of contamination; and
in the case of SCO-I, where it is suspected that non-fixed contamination exists on inaccessible surfaces in excess of the values specified in paragraph (a)(i) of Section B of the First Schedule, measures shall be taken to ensure the radioactive material is not released into the conveyance.
