Therefore, to provide a worst case scenario, these data served as an input for a case study in Singapore’s underground MRT system. It was found from literature reviews that a higher heat release rate and carbon monoxide concentration not only results in heat and respiratory inflammatory related injuries leading to death, but also impairs the judgement of an evacuee during an evacuation.
From the experiment, it was observed that amongst all the polymeric materials, polypropylene had the highest heat release rates of 1550kW/m2 with carbon monoxide and carbon dioxide yields of 0.075g/g and 4.5g/g respectively. To understand the characteristics of fire smoke and its influence on commuters, a laboratory experiment which uses a Cone Calorimeter was conducted to obtain the thermal properties of six common polymeric materials (polystyrene, polypropylene, high-density polyethylene, polymethyl methacrylate, polycarbonate and polyethylene terephthalate) that could be found in Singapore’s MRT system. As such, the purpose of this study is to study the fire smoke movement in Singapore’s MRT system and its effect on the evacuation behaviour of commuters.
This is an imperative concern as a fire breakout in the MRT system can result in dire consequences as seen in the Deagu (in South Korea) subway fire incident.
However, the recent train disruptions have shown the limitations of the train operator’s response and preparedness during an emergency. As Singapore’s population continues to increase, the ridership of the MRT will hit 4.5 million by 2020. The MRT system is the backbone of Singapore’s public transport with an average daily ridership of 2.124 million. Repository.įire safety is of paramount importance in every structure and its magnitude in populated underground structures such as the Mass Rapid Transit (MRT) is immeasurable.
