   Subpart K_Detailed Requirements for Class 7 (Radioactive) Materials
 
Sec.  174.750  Incidents involving leakage.

    (a) In addition to the incident reporting requirements of Sec.  Sec.  
171.15 and 171.16 of this subchapter, the carrier shall also notify the 
offeror at the earliest practicable moment following any incident in 
which there has been breakage, spillage, or suspected radioactive 
contamination involving Class 7 (radioactive) materials shipments. 
Transport vehicles, buildings, areas, or equipment in which Class 7 
(radioactive) materials have been spilled may not be again placed in 
service or routinely occupied until the radiation dose rate at every 
accessible surface is less than 0.005 mSv per hour (0.5 mrem per hour) 
and there is no significant removable radioactive surface contamination 
(see Sec.  173.443 of this subchapter).
    (b) The package or materials should be segregated as far as 
practicable from personnel contact. If radiological advice or assistance 
is needed, the U.S. Department of Energy (DOE) should also be notified. 
In case of obvious leakage, or if it appears likely that the inside 
container may have been damaged, care should be taken to avoid 
inhalation, ingestion, or contact with the Class 7 (radioactive) 
material. Any loose Class 7 (radioactive) materials should be left in a 
segregated area and held pending disposal instructions, from qualified 
persons.
