poor ventilation system. There were lock-ups which windows are small in size and covered for safety measures. Female cell in Lahad Datu Police Stationand male cell in Kluang Police Station lock-up do not have windows. Whereas in Penampang Stationlock-up, there are cells with no air holes or the available ones are too small. 4.48 Because the windows are not enough to assist the ventilation, most lock-ups are equipped with exhaust fan. However, it still does not overcome the problem of poor ventilation. Based on Table 12 below, there are 11 lock-ups which do not equipped with exhaust fan, 3 lock-ups have the broken ones and 5 lock-ups have insufficient exhaust fan. 4.49 Other than exhaust fan, regular fan is only used in several lock-ups. The presence of regular fan can assist the ventilation. Detaineesmet at lock-ups in Kuala Terengganu, Dungun, Kota Setar and Tabuan Jaya Police Stations, for instance, request the fan installation to create cold and better ventilation. 4.50 The Commission found the ventilation system in Bayan Baru Central Lock-up, Jitra Police Station (IPD Kubang Pasu) and Ranau Police Station (Sabah) is good due to the structure of the building. The presence of air holes assist in ventilation in cells. Lighting 4.51 The Commission examined that, just like the ventilation system, the lighting is also unsatisfying. The condition is even worse in old lock-ups. The absence of big windows and those which are covered due to safety measures limit the natural light coming through the windows. 4.52 There is poor lighting in Bintulu Police Station, Sarawak, and lock-ups in Kluang and Batu Pahat Police Stations in Johor. It is dark in BintuluPolice Station lockup as there are no lamps in all cells. Meanwhile it is dark in male lock-up in KluangPolice Station as there are no lamps nonetheless there is good lighting in female lock-up. 77
