Respondent positions A position is what a respondent says about the concern when they do not describe a specific action.2
HM Prison and Probation Service
Existing guidance, local accommodation discretion, risk oversight and established safeguards are considered sufficient to manage PCOSO safety without universal separation.
Existing arrangements considered sufficientThe respondent said that existing arrangements were sufficient, so no further action was needed.
HM Prison and Probation Service
Complete separation of PCOSOs from the wider prison population is not always operationally feasible, so it cannot be maintained universally.
