Prior to any calculated use of force, the ranking custodial official (ordinarily the Captain or shift Lieutenant), a designated mental health professional, and others shall confer and gather pertinent information about the inmate and the immediate situation. Based on their assessment of that information, they shall identify a staff member(s) to attempt to obtain the inmate's voluntary cooperation and, using the knowledge they have gained about the inmate and the incident, determine if use of force is necessary.
