Final answer:
The SF 312 is a mandatory document required for employees accessing classified information, contrasting the nine FOIA exemptions. Refusal to sign must be reported to the PSMO-I.
Step-by-step explanation:
The SF 312, Classified Information Nondisclosure Agreement, is not optional but a mandatory document that employees with access to classified information must sign.
In contrast to the nine exemptions cited by the Freedom of Information Act (FOIA) related to national security, internal personnel rules, trade secrets, violations of personnel privacy rights, law enforcement information, and oil well data, the SF 312 is a firm requirement.
If a cleared employee refuses to sign the SF 312, it is necessary to report this to the Personnel Security Management Office for Industry (PSMO-I), as it could indicate a potential security risk.
