Inmates who pose a substantial risk and require constant minute-to-minute supervision should be classified as maximum custody. This classification is designed for individuals who may present a danger to themselves, others, and security protocols within a correctional facility. Maximum custody units are implemented to ensure that these inmates are closely monitored at all times, minimizing any potential threats they may pose.

Unlike medium or minimum custody, where inmates might have more freedoms or less stringent supervision, maximum custody ensures that every interaction and movement is monitored. This heightened level of supervision is crucial for maintaining safety and control within the correctional environment, as these inmates often have histories of violent behavior, escape attempts, or other serious offenses that necessitate increased oversight.

Personal custody, while it may imply closer supervision, is not an established classification in the same manner as the others and generally does not recognize the specific security level requirements for high-risk inmates. The determination of maximum custody reflects a formal and standardized approach to managing inmates who require heightened supervision due to their behavior or potential for causing disruption.
