Handling Chemical-terrorism Vulnerability Information

Anyone with access to Chemical-terrorism Vulnerability Information (CVI) must follow the specific requirements established in the implementing regulations (6 CFR Part 27) and should be familiar with the Infrastructure Security Compliance Division CVI Procedural Manual (PDF, 28 pages - 242 KB ), and in any additional directive or policy issued by the Chemical Security Compliance Division.

Generally, materials containing CVI must be appropriately designated and withheld from public disclosure. CVI must also be physically controlled and protected. The protections include:

  • Storage of CVI
  • Marking of CVI
  • Transmission of CVI
  • Responsibilities when in transit with CVI
  • Destruction of CVI.
