The ability for staff to clean the skylight should be considered. Some facilities report the need for regular maintenance calls due to the complex assembly. Access to the plumbing area should not be available from the sleeping room. For example, one should not have access to the chase corridor by removing the toilet. When the plumbing chase corridor is located on an outer wall of the facility, it should be secure enough to prevent attempts from outsiders to penetrate security.
Staff needs access to the plumbing chase to turn water off in emergency situations.
With a plumbing chase corridor, safe access to the upper level fixtures must be considered for facilities with two levels of sleeping rooms. Thought must then be given to installing a modesty partition to prevent such direct visual observation. This may result in blind spots. The purpose of a modesty partition is to facilitate cross-gender supervision, not modesty between individuals housed in the cell or dorm. Exceptions to this include some special purpose cells such as detoxification or safety cells.
