  • Although the urban rail vehicle is exposed to the fire disaster, most country, except only a few advanced country, is insufficient to take a measure against the fire accident. Safety regulation modification, fire safety standard of the materials. and each material's fire resistance of the rail vehicle have been upgraded until the Daegu fire disaster in Korea. For that reason, In this study, current techniques of fire safety evaluation are analyzed and fire safety degrees of rail vehicles are compared with the change of interiors which is met to the fire safety standard of urban rail vehicle.

  • A large-scale fire test was done for interior materials from a vehicle installed within a fire test room. The interior materials are satisfied with the Korean guide for the safety of rail vehicle. The guide has taken effect since December 2004 in Korea. Ignition source (gas burner) was increased in several controlled steps. The objectives of this test are to assess the fire performance in terms of ignition and flame spread on interior lining materials and to provide data on an enclosure fires involving train interior materials that grow to flashover. This data will be used to develop and calibrate an Fire Dynamics Simulator (FDS) model for fire growth on the interior vehicle.

  • In this study, the authors designed a reduced-scale railway vehicle fire, which was necessary for evaluating the fire safety of railway tunnels using a reduced model. To overcome the shortcomings of the methods used in conventional reduced-scale railway tunnel tests, the authors simulated the fire source of a railway vehicle using a methanol fire source for fire buoyancy, and a smoke cartridge for smoke visualization. Therefore, the heat release mass consumption rates of various methane trays were measured using a cone calorimeter (ISO 5660). The critical ventilation velocity in the railway tunnels was obtained using the designed fire source of the railway vehicle, which was evaluated by the measured temperature at the top of the tunnel as well as laser visualization.

  • A large-scale fire test was conducted for interior materials from a vehicle installed within a fire test room (ISO 9705). The interior materials are satisfying the Korean guideline for the safety of rail vehicles, where the guideline has taken effect since December 2004 in Korea. The output of ignition source (gas burner) was increased in several controlled steps. The objectives of this test are to assess the fire performance in terms of ignition and flame spread on interior lining materials and to provide data on an enclosure fires involving train interior materials that grow to flashover. These data will be used to develop and calibrate models for fire growth on the interiors of the railway vehicle.

  • In this study, we investigated the operation of railroad fire fighting vehicles against fires on trains in a long railway tunnel. In recent years, long railway tunnels (more than 10 km in length) have been built and the number of such tunnels, such as the Geumjeong tunnel (20.3 km in length) on the Gyeongbu high speed line, Solan tunnel (16.7 km in length) on the Yeongdong line and Yulhyeon tunnel (50.3 km in length) on the Suseo high speed line which is scheduled to be opened in the second half of 2016, is increasing. Significant damage is to be expected, due to the increased evacuation time and limited accessibility of fire services when the train is stopped by an urgent fire in the tunnel. Special fire fighting vehicles capable of running on rails have been developed and operated in overseas advanced countries. Therefore, a fire-response system using Unimog vehicles, which can run on road and rail, instead of road vehicles, is necessary. The characteristics of the railway tunnel and thermal environmental change caused by a train fire in a tunnel were analyzed in this study. Also, the operational requirements of the railroad fire fighting vehicles were evaluated by taking into account the specifications of the railroad fire fighting vehicles under development.

  • Nowadays, concerns have much more growing regarding indoor air quality (IAQ) on the public transportation including railway vehicles. Last year Korea Ministry of Environment (ME) set new guideline for public transportation. In this study several factors were analyzed which may affect comfortableness of railway passenger cabin, and we monitored IAQ parameters (PM10, CO, $CO_2$, VOCs, temperature and humidity) to investigate the present pollution in passenger cabin. In general, the railway air quality was satisfactory. The PM10 and $CO_2$ level on all passenger cabin were below the new guideline level 1 for PM10 $(200{\mu}g/m^3)\;and\;CO_2(2,000ppm)$. Clustering method was carried out to classify the air polluting pattern of the cabin. As a result, the pollutants could be classified to 4 clusters and the origin of pollution is soil, diesel exhaust gas, abrasion of rail and plume.

  • This study analyzed the regulatory actions of disposal gas lighters as well as the situations, causes, and preventive measures of fires, and accidents caused by disposal gas lighters. Since child-resistant lighters became mandatory, the percentage of fires caused by playing with fire has decreased in Korea as it did in America and Japan. Fires caused by disposal gas lighters can occur by afterburning, unintentional lighting, large flames, or explosion or bursting as well as by arson and playing with fire. This study suggests the preventive measures of fires caused by disposal gas lighters as follows: Taking a step not to be used as child's tool for playing with fire, the warning of fire cases caused by afterburning, warning of the dangers of leaving disposal gas lighters on the car dashboard or high temperature places, improving the protective synthetic resin cover of the stop part of a vehicle seat rail, and providing information on precautions for keeping in drawers or disposition methods.
