Training for Chemical-terrorism Vulnerability Information

CVI Authorized User Training provides an overview of a Sensitive But Unclassified designation titled "Chemical-terrorism Vulnerability Information” (CVI). CVI is used to protect information developed under Chemical Facility Anti-Terrorism Standards (CFATS) regulation that relates to vulnerabilities to terrorist attacks of high-risk chemical facilities manufacturing, using, storing or otherwise possessing certain explosive, reactive, flammable, or toxic chemicals of interest. Completion of this training will prepare you to successfully handle and safeguard CVI.

Completion of this training and the CVI Authorized User Application is a necessary step to become a CVI Authorized User.

This training does not make any determination on your need to know CVI. The holder of CVI or an appropriate Department of Homeland Security official will make this decision each time a request for access to, or for disclosure of, CVI is made.

DHS will review the information you provide upon completion of this training and, if you are approved as a CVI Authorized User, DHS will notify you with an email providing a unique CVI Authorized User number and certificate to confirm your status.

If you have any difficulty with submitting the CVI Authorized User Application, please e-mail the CSAT Help Desk at or call at 866-323-2957. Hours are from 7:00 AM to 7:00 PM ET Monday to Friday. The CSAT Help Desk is closed on Federal Holidays.
