LRAFB SFPC Safeguarding Classified Information in the NISP Practice Test

The key idea is that the lock on a GSA-approved container stays usable as long as it works reliably. If the lock functions properly, there’s no need to replace it just because it’s old. Regular checks should catch wear, damage, or signs of tampering, and if any of those occur, the lock should be replaced with an approved one to keep the container secure. Replacing immediately without a problem isn’t required, claiming it must be used forever ignoring wear isn’t correct, and needing DoD approval isn’t part of normal practice for continuing use of a GSA-approved container.
