Following the Top One Karaoke blaze in Tsim Sha Tsui, Hong Kong in early 1997, the Hong Kong Government has set up an inter-departmental working group to co-ordinate efforts in planning for the control of karaoke establishments. In the fire, the victims were killed by smoke and their bodies were found in the corridor of the karaoke. It has been considered that the way the karaoke premises are partitioned into a number of small cubicles is likely to pose problems in case of fire and should be subject to stringent control. As karaoke establishments are of high population density, evacuation becomes the major concern of the controlling authority. A minimum width of 1200mm for the internal corridor has been suggested as an additional requirement to the standards prescribed by the fire codes in Hong Kong. This article provides an analytical study on the effect of corridor width on the evacuation time which can be considered as a major dimension in measuring the safeness of an establishment.
