Most of the correctional institutions have been in operation for decades. To keep pace with the times, the Department has been working closely with the Architectural Services Department and the Electrical and Mechanical Services Department to implement practicable measures to upgrade the facilities of correctional institutions gradually, having regard to the design and security concerns of individual institutions.
With a view to speeding up emergency support, strengthening institutional security and enhancing management efficiency, the Department has obtained funding approval from the Legislative Council for the progressive installation of the Electric Locks Security Systems to replace old gates using manually-operated mechanical locks with electric grille gates at most of the passageways, cells and relevant facilities of maximum security institutions (including Stanley Prison, Pik Uk Correctional Institution, Shek Pik Prison, Siu Lam Psychiatric Centre and Tai Lam Centre for Women (non-redevelopment areas)). As of end of 2021, the works project at Tai Lam Centre for Women (non-redevelopment areas) was smoothly completed, while the works projects at Stanley Prison and Shek Pik Prison were still in progress and those at the 2 remaining institutions were about to commence.
Besides, the CSD has been installing digital closed-circuit television (CCTV) systems at correctional institutions, and is studying the feasibility of incorporating the body temperature detection function into the CCTV systems to ensure a safe custodial environment and help monitor the health condition of persons in custody. The relevant projects, upon completion, are expected to further enhance the security level and reduce the risk of virus transmission within correctional institutions.
Within the year of 2021, the CSD adopted a number of measures to improve the custodial environment during the year, including improving the air ventilation at correctional institutions. On top of the regular replacement of electric fans, horn fans with greater power and cell safety fans with a suicide prevention design were added and new grille gates and windows allowing better air flow were also progressively installed in correctional institutions, with a view to improving air ventilation.
