(b) The Warden shall consider the following factors in a recommendation for control unit placement.

4. (4) Any incident in which the inmate is involved in a disruption of the orderly operation of a prison, jail or other correctional institution.
5. (5) An escape from a correctional institution.
6. (6) An escape attempt. Depending on the circumstances, an escape attempt, considered alone or together with an inmate's prior history, may warrant consideration for a control unit placement.
7. (7) The nature of the offense for which committed.

(c) The Warden may not refer an inmate for placement in a control unit:

1. (1) If the inmate shows evidence of significant mental disorder or major physical disabilities as documented in a mental health evaluation or a physical examination;
2. (2) On the basis that the inmate is a protection case, e.g., a homosexual, an informant, etc., unless the inmate meets other criteria as described in paragraph (b) of this section.
