Level A documents are public information. Level B: not accessible by inmates but accessible to officers, sergeants, and management. Level B documents generally deal with normal facility opera- tions. Level C: confidential (but not emergency-related) information. Level C doc- uments generally deal with confidential personnel information. These docu- ments are available to sergeants and above, but not to officers and inmates. Level D: emergency-response information.
