Corrections Act 2004, s 60; Prison Operations Manual, M.05.03
If you’ve been assessed as “at risk” (that is, at risk of harming yourself) you’ll be separated from the main prison population and placed in a cell by yourself – this is called “segregation”. You’ll be visited at least twice a day by a doctor or nurse, who’ll make further assessments.
Many prisons have a special “at risk” unit. No glass or sharp objects are allowed in these cells, including TVs and radios. Generally these have a high staff presence and the prisoners in the units are closely monitored.
