As population grows and urban facilities are concentrated in specific areas due to recent urbanization and industrialization, cities have structures vulnerable to both natural and man-made disasters. Most of these structures, whether buildings or residential houses, are left in a defenseless state if not given the appropriate check-up before they are built. The process of rapid urbanization without establishing the proper urban fire risk assessment will surely lead to disasters. This phenomenon occurred during the process of rapid urbanization and maybe said the result of chaotic urban expansion where modern urban infrastructure is not yet equipped in the city. Under the said circumstances, propagation processes of Korean urban fire cases were investigated to establish fire risk assessment system. Moreover, this paper explains the experiment performed for establishing urban risk assessment model. The said experiment was conducted using the new urban fire risk assessment model.

Yoo, Suk-Hyeong ; Lim, Seo-Hyeong ;
Fire Science and Engineering, volume 25, issue 6, 2011, Pages 8~13
High Strength Concrete (HSC) has a disadvantage of the brittle failure under fire due to the spalling. The studies on spalling control method of new constructed HSC buildings were performed enough, but the studies on existing buildings are insufficient. The new inorganic refractory mortar is developed in this study. The insulating capacity is enhanced by using light weight fine aggregate and polypropylene (PP) fiber. In results of material test, the thermal conductivity of light weight fine aggregate get lower than general fine aggregate. And in results of column test, the fire resisting time is delayed 20 minutes by using light weight fine aggregate, 10 minutes by increasing finishing depth from 10 mm to 20 mm and 4 minutes by using 0.6 % PP fiber.

Fire Science and Engineering, volume 25, issue 6, 2011, Pages 14~20
It is very difficult for fire investigators to analyze the fire debris in fire scene to figure out the reason of fire. ASTM E 1618 method with Gas Chromatoghraphy-Mass Spectrometry was used to analyze the ignitable liquid residues in fire debris prepared in our laboratory. According to fire cases, sample handling procedure methods and fire debris store time, different total ion chromatograms were obtained. We wish the study will be helpful to fire investigators to figure out the reason of fire.
Study on the Analysis of Damage Patterns of Cellular Phone Batteries According to Energy Sources
Choi, Chung-Seog ;
Fire Science and Engineering, volume 25, issue 6, 2011, Pages 21~26
The purpose of this paper is to present the damage patterns of cellular phone (SCH_W830) batteries according to energy sources and have them utilized as data for the settlement of disputes between manufactures and consumers. The reliability was secured by maintaining the ambient temperature and humidity at
and 40~60 %, respectively. The voltage of the battery used for the tests was measured to be 4.18V between positive pole (+) and negative pole (-)(1), and 4.19 V between positive pole (+) and negative pole (-)(2). This study applied the Korean Industrial Standard (KS) to the flammability test of cellular phones due to a general flame applied to them and found that no damage occurred to the built-in battery even though the flame was applied to the cases of cellular phones for 30 seconds. From the results of immersing the cellular phones in the saline solution (NaCl, 0.9 %) for 180 seconds, it was found that there was a trace of carbonization and melting due to the heat caused by leaking current. It can be seen that when the cellular phones were heated for 70 seconds using a microwave oven (MWO), the areas containing the metal holder, recharging connector, antenna, etc., were melted and discolored and that other areas showed no particular problems. That is, while the external carbonization of cellular phones, built-in metals and dielectric materials, and damage and deformation of the battery terminal block, etc., occurred differently depending on the types of energy sources, the voltage showed comparatively constant characteristics. Therefore, it is thought to be possible to attribute the cause of damage to the battery by performing analysis taking into consideration comprehensively the characteristics of the flame spread pattern as well as the melting and deformation of metals.

As the using rate of an explosive gas has been increased in the industrial site, the regional residents adjacent to the site as well as the site workers have frequently fallen into a dangerous situation. Damage caused by accident in the process using hydrogen gas is not confined only to the relevant process, but also is linked to a large scale of fire or explosion and it bring about heavy casualties. Therefore, personnel in charge should investigate the kinds and causes of the accident, forecast the scale of damage and also, shall establish and manage safety countermeasures. We, in Anti-Calamity Research Center, forecasted the scope of danger if break out a fire or/and explosion in hydrogen gas facilities of MLCC firing process. We selected piping leak accident, which is the most frequent accident case based on an actual analysis of accident data occurred. We select and apply piping leak accident which is the most frequent case based on an actual accident data as a model of damage forecasting scenario caused by accident. A jet fire breaks out if hydrogen gas leaks through pipe size of 10 mm
under pressure of 120 bar, and in case of
of radiation level, the radiation heat can produce an effect on up to distance of maximum 12.45 meter. Herein, we are going to recommend safety security and countermeasures for improvement through forecasting of accident damages.

Fire Science and Engineering, volume 25, issue 6, 2011, Pages 58~63
This study is intended to present a computational thermal model for the combustibles in a residential building. As the Performance Based Design is more popular, fire-intensity and fire-load have turned out to be very important factors for building design and can be predicted through some computational work. To predict and estimate the thermal properties of the residential combustible fire, we made some numerical models of combustibles in a residential building. In a bid to validate the estimate values, computational analysis results from numerical models were compared with real fire tests. For computational analysis, the Fire Dynamics Simulator was used with Large Eddy Simulation model for turbulence. Consequently, each heat release rate and total heat release curves were successfully estimated.

Fire Science and Engineering, volume 25, issue 6, 2011, Pages 64~72
The concrete void slab structure with the existing mushroom slab, is the structure that maximizes the advantages, while minimizing the weakness with removing useless body force of the concrete part, located on the center of the slab cross-section, which does not need to support the structural weight. In this research, a fire test is performed to analyze how the blaze behave according to the thickness of slab cover, with the practical span length of concrete void slab for the slab length 7.5 m. With this heating test, we assumed the uniform-load-model considering fixed loads and live loads, and chose the standard fire test condition. We measured the temperature changes and the deflection character according to the depth from the heat exposure side, and assessed the resisting capability according to the standard KS F 2257-1. The result comes out with the EPS model can secure about 2 hour fire-resisting-capability with 50 mm of cover depth.

This study was performed to analysis the influence of smoke alarm detector on evacuation safety in housing fire. The analysis was conducted by CFAST fire simulation program and building EXODUS evacuation program. The effects of the earlier response time on evacuation safety were investigated by using evacuation simulation program with several steps of different response time and smoke alarm activation time for 4 occupants. The smoke detecter was activated 37.1 second after fire. The first two mortuary were occurred for 170 seconds of response time at the end of living room near exit. But for the 37.1 seconds of response time 4 occupants evacuated safely. From this study, the fire alarm detector is more important for safety evacuation in housing fire.

Choi, Chung-Seog ;
Fire Science and Engineering, volume 25, issue 6, 2011, Pages 83~88
This study presented the structure and characteristics of vinyl cords used for wiring electric equipment and appliances and analyzed the photographs of damaged flat-type vinyl cords (VFF,
) and the metallic cross-sectional structure of melted conductors. Normal VFFs were made by twisting several strands together and the surface of the conductor was red brown. In addition, from the analysis of the metallic structure of the conductor, it was found that its grains had been elongated. The surface of a VFF damaged by normal flame showed no sheen with carbonized insulation material fused on the conductor surface. In addition, from the analysis of the cross-sectional structure of the melted area, it was found that voids of a certain shape were formed on it but that the cord's own elongation structure could not be checked. The cross-sectional analysis of the melted conductor damaged by the external flame applied to a VFF to which electric current was being applied showed no elongation structure for each cord, and revealed that irregular voids and a columnar structure had grown. The surface of the VFF damaged by overcurrent was uniformly carbonized and the cross-sectional structure analysis of the melted conductor revealed that the dendritic structure had grown. The analysis of the characteristics of the VFF melted by short-circuit showed that even though some part of the surface was contaminated, it showed little sheen and that the area rebounded by melting was round in shape. In addition, the cross-sectional structure analysis using a metallurgical microscope showed the boundary surface and columnar structure and revealed an amorphous structure like normal copper at areas other than the melted conductor.

Fire Science and Engineering, volume 25, issue 6, 2011, Pages 89~97
This study is for evaluating the fire resistance performance (1~2 h) of the RC Structure void slab using the Lightweight Hollow Sphere, which can reduce the unnecessary dynamic part of removing the central concrete. For this experiment, we set up depth of concrete cover, live load, and span length as the factors. The result comes out with all the slabs under those conditions can ensure the goal fire resistance performance (120 min). And among these factors, the resisting capability changes more sensitively with the live load rather than the thickness of cover. And the shorter span length could assure the better the fire resistance performance. The result observing the character in high temperature of the Lightweight Hollow Sphere which does not used as existing RC structure slab, a delay section in temperature change is occurred due to the Glass Transition in
. And heat transfer by conduction does not occur at lightweight hollow sphere because the polystyrene in EPS (Expanded Polystyrene) melts point in
. Therefore temperature at lightweight hollow sphere is lower than the concrete and rebar.

Fire Science and Engineering, volume 25, issue 6, 2011, Pages 104~111
Aluminum has been widely used as frame materials in the curtain walls. Recently, use of steel as a curtain wall frame is being considered due to its higher strength and thermal resistance than aluminum. In this study, fire tests on the basis of EN 13830 were performed with aluminum and steel-aluminum hybrid curtain walls. From the tests, fire resistance integrity, thermal insulation, and radiation properties were evaluated for both systems and compared. According to the test results, the steel-aluminum hybrid curtain wall showed better fire-performance than the typical aluminum curtain wall for the fire resistance integrity and radiation properties. Although, the fire resistance performance for the insulation property was 6 min for both the two frames, the collapses were occurred at 36 min for the steel-aluminum hybrid curtain wall and at 13 min for the aluminum hybrid curtain wall.

Park, Yong-Hwan ; Kim, Beom-Gyu ; Lim, Chae-Hyun ;
Fire Science and Engineering, volume 25, issue 6, 2011, Pages 120~126
Recently luminous egress guide-lines are introduced for the fire safety of residents in the multi-use buildings such as Gosiwon. Little literature, however, on the quantitative and qualitative estimation for the egress performance of the luminous egress guide-lines can be found. This study carried out experimental investigations to evaluate the egress performance of the existing egress guide-lights and new luminous egress guide-lines. The results showed that both luminous egress guide-lines and egress guide-light satisfied the basic performance of KFI requirements. Under the 7 % smoke transmittance, however, luminous egress guide-lines showed 3 times longer visibility and less evacuation time than egress guide-lights. The evacuation density and smoke transmittance have significant effect on the evacuation time increase without the luminous egress guide-lines, however little effect with the installation.

Min, Se-Hong ; Lee, Jae-Moon ; Sa, Jae-Cheon ; Nam, Jung-O ;
Fire Science and Engineering, volume 25, issue 6, 2011, Pages 127~135
In this study, we assumed the kitchen fire raising the highest fire rate in apt. and analyzed the fire risk to use CFD in order to estimate the problem of evacuation equipment and the fire vulnerability of 16 or fewer storey apartment. Fire occurring in the kitchen is expended to the livingroom and other rooms. We analyzed that the temperature effected by heat was more than
after 90 sec in the entrance of apartment unit. If fire is early recognized by men and men don't escape in time, it have too huge demage to block the exit. When the evacuation equipment suggested in this study was installed in order to solve the problem of evacuation equipment, we analyzed that it was estimated more than safe in safety evaluation by heat and heat flux.

Fire Science and Engineering, volume 25, issue 6, 2011, Pages 168~177
The combustion test for real box of AC outdoor unit has been performed in this study in order to estimate the fire hazard in multi-system type of AC outdoor unit which is currently used for commercial use. The result showed that in test, there was explosion inside of AC outdoor unit, and flame erupted and fire spread through upper side grill. And then this fire burnt the combustibles such as wires, electronic control board, heat exchange copper plate and plastics etc inside the unit, refrigerant gas pipe was burst due to fire, and accelerated the explosion and flame eruption to outside while the refrigerant was erupting. It is found in this test that the maximum heat release rate of AC outdoor unit is 5,830 kW, the maximum internal temperature measured with infrared camera and thermocouple is
, maximum ambient temperature is
, and flame rose higher than about 5 m. It is concluded that the fire in AC outdoor unit cause fire to combustibles around the unit, and may give big damage by generating the secondary fire. It is expected that the result obtained from the test on the real object may be applied to fire realization of AC outdoor unit and estimation of fire spreading to the combustibles around in the future computer simulation.

Kim, Jin-Soo ; Lee, Eui-Pyeong ;
Fire Science and Engineering, volume 25, issue 6, 2011, Pages 178~183
In cold season, the elevator systems in super high-rise buildings would make noises at the door-gaps on high floors, and the elevator doors on the 1st floor would suffer from opening/closing trouble due to the pressure differences. Such pressure differences are also the main driving power of smokes through the hoistway in the case of fire. In addition, the pressure differences should be overcome to use the elevator systems as a measure of emergency escape. This paper reviews the way of hoistway pressurization to reduce the adverse influences. Simulations achieved a good result close to the requirements of NFPA 92A and IBC 2012 under the condition that the hoistway should be pressurized after pressure equalizing between floors and hoistway with the openings through the hoistway wall.

Chung, Yeong-Jin ;
Fire Science and Engineering, volume 25, issue 6, 2011, Pages 190~195
Effects of ethylene-propylene diene monomer (EPDM)/polypropylene (PP), zinc oxide, stearic acid, and clay on the combustive properties based on EPDM/PP were investigated. The EPDM/PP/clay nanocomposites was compounded to prepare specimen for combustive analysis by cone calorimeter (ISO 5660-1). It was found that the combustive properties in the nanocomposites decreased due to the fire resistance compared with unfilld EDPM/PP. The nanocomposites showed the lower peak heat release rate (PHRR) than that of virgin EPDM/PP, while stearic acid for softening ruber increased the mean heat release rate (MHRR) by itself, combustible.
