Shredders for unclassified information and Controlled Unclassified Information are located in designated business centers throughout the Herbert C. Hoover Building (HCHB). Business Centers are accessible 24/7 for employee convenience. Employees are responsible for shredding their own documents. Documents are not to be left unattended or not shredded. Please do not place candy wrappers, food items, glass, or other hazardous materials in shredders. Please ensure all unclassified documents do not have comingled classified information. Inspect each page for classified markings.

Every attempt should be made to shred classified national security materials in a designated secure space such as collateral Secret secure spaces or Secure Compartmented Information Facilities. The shredding of classified national security materials must occur using National Security Agency–approved shredders, which are designated for the destruction of the identified documents at the commensurate classification level. Special appointments for classified document destruction can be made with the HCHB Security Service Center if an NSA-approved shredder is not available. To schedule an appointment for classified document destruction, please call the HCHB Security Service Center at 202-482-8355. After hours, call HCHB Dispatch at 202-482-4584.
