Hi Robert,
Based on ACA 3-ALDF-3D-08 (Ref: New) it states the following: "Written policy, procedure, and practice require that all special management inmates are personally observed by a correctional officer at least every 30 minutes on an irregular schedule. Inmates who are violent or mentally disordered or who demonstrate unusual or bizarre behavior receive more frequent observation; suicidal inmates are under continuous observation."
There are other ACA standards that addresses supervision of inmates. I strongly recommend that you purchase a copy of the ACA standards.
