When does a Positive Hand-off of Rail Security-Sensitive Materials (RSSM) need to be made?

A Positive Hand-off of Rail Security-Sensitive Materials (RSSM) needs to be made when receiving an RSSM shipment from the shipper or during interchanges. This process is critical in ensuring that the materials are accounted for and securely transferred between different parties involved in the transport.

The significance of this procedure lies in the high-security nature of RSSM, which can include items that have the potential to pose a safety or security risk if not handled appropriately. By ensuring there is a clear and documented hand-off process in place, it minimizes the risk of mishandling or loss of such materials.

At the point of receiving, proper verification procedures can be implemented to ascertain that the correct materials are being received and that they match with the shipping documentation. This step is essential to maintain a reliable and secure transportation process.

Other options do not represent necessary points for a Positive Hand-off regarding RSSM, as the primary emphasis is on the initial receiving and interchanging of these sensitive materials.
