In the intake procedure, the classification of jail inmates is difficult given the dearth of inmate history and the lack of space to separate offenders with such a varied range of crimes, social and psychological backgrounds, and physical characteristics. These factors increase the risk of jail liability. To compensate for these difficulties, appropriate security procedures must be developed and followed. In jails without direct supervision, the frequent observation of living units is required. One of the most reliable means of avoiding jail liability is to become accredited under American Correctional Association jail standards and receive periodic reviews for accreditation under updated standards. A close working relationship between jail staff and the designated government attorney is also valuable. Proposed changes in management procedure and structure should be discussed with the attorney prior to implementation. Staff selection and training is important in the reduction of the liability risk. Documentation is also crucial in any liability defense. Documentation should include incident reports, pass-down logs, exercise logs, medical records, classification records, inmate request and grievance forms, and disciplinary proceedings. The staff training program for the Lancaster County Jail is described.
