Choi, Jae-Wook ; Mok, Yun-Soo ; Choi, Il-Gon ; Jeon, Se-Ho ; Lim, Woo-Sub ; Min, Chul-Woong ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 1~5
The spontaneous ignition of a flammable matter is a crucial factor for the prevention of a fire. The minimum ignition temperatures of Gasoline and Cenox in
of a sample were determined to be
respectively. In addition when the time taken for ignition was 1.0 sec, the instantaneous ignition temperatures were
respectively. Moreover, the changes in the minimum ignition temperature were small when less than 60 v/v% of Cenox was added, but the changes were great when 80 v/v% or more was added. Therefore, it is hypothesized that, when used as a fuel in the Gasoline engine, the ratio of the mixture of Cenox and Gasoline will be a very important factor.

Fire Science and Engineering, volume 20, issue 1, 2006, Pages 6~14
The data of city gas accidents has been collected and analysed for not only predictions of the fire and explosion accidents but also the criteria of societal risk. The accidents of the recent 11 years have been broken up into such 3 groups roughly as "release", "explosion", "fire" d 16 groups in detail. Owing to the Poisson probability distribution functions, 'careless work-explosion-pipeline' and 'joint loosening & erosion-release-pipeline' items respectively have turned out to record the lowest and most frequency among the recent 11-years accidents. And thus the proper counteractions must be carried out. In order to assess the societal risks tendency of the fatal gas accidents and set the more obvious safety policies up, the D. O. Hogon equation and the regression method has been used to range the acceptable range in the F-N curve of the cumulative casualties. The further works requires setting up successive database on the fire and explosion accidents systematically to obtain reliable analyses. Also the standard codification will be demanded.

Bang, Chang-Hoon ; Chung, Kye-Young ; Lee, Yong-Joo ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 15~22
This study intends to raise the fire safety awareness level which the teachers have in infant schools. The results of the study are as follows. The early childhood teachers consider the fire safety awareness level of our society low, though their fire safety awareness level be above the average. The education program for the fire safety is mapped out and the teachers prefer an observation class and a field trip for the program in almost infant schools. The early childhood teachers have difficulty acquiring the knowledge for the field experience and work and getting teaching aids for the fire safety. Therefore the early childhood teachers extremely much desire teaching aids for infants to be developed and diffused.

With the development of the today's advanced industry civilization, We are always inhering a safety frigidity about disasters of various kinds when and where we may happen. The fires and disasters to be enlarged day by day are reported everyday through the mass communication. Therefore, a prevention countermeasure about the every kind fire and disaster is above all important along the social and the days requirement. As a kind of such countermeasure, this paper is proposed about automatic transmission system of disasters alarm by using wire and wireless communication network. The automatic transmission system prevents the unexpected fire or disaster from a sudden occurrence at the house, industrial field or at the place without the human. The proposed system has the characteristic of high precision and high response speed comparing with conventional system. Also, as the proposed system is small size and lightweight, the users have economic advantage and simply install the system.

Shong, Kil-Mok ; Han, Woon-Ki ; Kim, Young-Seok ; Choi, Chung-Seog ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 43~49
In this paper, we are studied on the temperature characteristics and fire progress of an incandescent electric lamp at 220V/100W. In the case of stationary state, the ignition possibility of the incandescent electric lamp due to the heat generation was low because the temperature was measured at
the temperature was increased at
in the airtight chamber, but it does not generated the fire because the oxygen was not exist in the airtight chamber. When the lamp is broken, the filament of lamp was melted in the air. The gas of lamp interior spurted to the weakest part by external flame. Thus, the incandescent electric lamp is high possibility of fire when oxygens from airtight space. Also, it is known that the possibility of ignition is very high if combustion materials(sawdust) exists on surrounding. These experimental results will be utilized for the data in the investigation electrical fire cause.
Smoke Control in a Subway Station Platform with Screen Doors - Based on Busan Subway Line 3 -
Park, Woe-Chul ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 50~54
A fire in a subway station platform, completely isolated by screen doors, was numerically simulated to investigate problems in smoke control and find their countermeasures. A part of the platform,
floor and 3 m high, and a fire of 1 MW were considered, and the smoke extraction system was assumed to start operation at the onset of the fire. For three different values of the exhaust air flow rate, 0.1, 2, and
, the distributions of temperature, concentrations of soot and carbon monoxide, and those of visibility were compared. The time-variations of the number of randomly distributed particles in the space were also investigated for the air flow rates to see the efficiency in smoke control. It was shown that smoke control takes time by lack of air supply. It was also confirmed that air supply from the railway to the platform at emergency is needed so that smoke is able to be controlled efficiently, and that opening the doors at the both ends of the platform is desirable until the fire is completely extinguished.
Analysis on Deployment of Fire Service Force in Korea
Back, Min-Ho ; Lee, Hae-Pyeong ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 55~70
The purpose of this study is to analyze an adequate deployment of fire service force to be prepared to respond appropriately and effectively in Korea by settlement pattern. In order to examine the deployment of fire service force by the present standard, we analyzed the logical basis and the deployment of fire service force by city and province. We also classified clusters for settlement pattern through the statistical methods and raised several points for the existing deployment model of fire service force by the classified settlement pattern. As a result, it was confirmed that the deployment of fire service force by the settlement pattern was irrelevant to fire service need.
A Study on Auxiliary Control Safety Apparatus for RCD Trip on Electric Arc and Spark Disasters - Using by Power Semiconductor Switching Device -
Kwak, Dong-Kurl ; Shin, Mi-Young ; Jung, Do-Young ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 71~76
The major causes of electrical fire are classified to short circuit fault, overload fault, electric leakage and electric contact failure. The occurrence factor of the fire is electric arc or spark accompanied with electrical faults. Residual Current Protective Device(RCD) of high sensitivity type used at low voltage wiring cuts off earth leakage and overload, but the RCD can't cut off electric arc or spark to be a major factor of electrical fire. As the RCDs which are applied low voltage distribution panel are prescribed to rated breaking time about 30[ms](KS C 4613), the RCDs can't perceive to the periodic electric arc or spark of more short wavelength level. To be improved on such problem, this paper is proposed to a auxiliary control apparatus for RCD trip on electric arc or spark due to electrical fire. Some experimental results of the proposed apparatus is confirmed to the validity of the analytical results.
A Study on the Controller of Integration Smoke Control System
Lee, Dong-Myung ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 77~82
This study defined engineering mechanism and compensation method to establish reference pressure of smoke control zone with atmospheric pressure that is compensated for temperature. The reliable controller of integration smoke control was developed by establishing the specifications, algorithms and constructing engineering data. The development of controller for integration smoke control can cut down number of processes, manufacturing and installation cost by removing pressure measurement pipe established separately for non smoke control zone, and improve the accuracy of pressure differential by embedding pressure measurement ports for non smoke control zone. More correct and reliable pressure differentials can be obtained by the central control from controller of integration smoke control rather than the existent individual control. This will provide the basics and the flexibility to the integral smoke control system and accordingly improve the performance of disaster prevention.
The Plan of Funds Expansion for Fire Services to Fix Safe Environment
Choi, Nag-Soon ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 83~97
Recently, it is imperatively necessary to expand fire services funds for providing high quality of fire services. This study is to propose the plan of funds expansion for fire services to cope with a hefty increase of fire services demands in a local autonomous entity era. As alternatives of funds expansion, the study suggests the increase of fire public facilities tax rate and extracting new funds by establishing local government firms such as fire hospitals and fire repair firms. In addition, the study also proposes establishing a new common fire facilities tax, imposing fire services tax on gas tax, imposing public facilities tax on electricity tax, and transferring fire services expense to a local autonomous entity.
Analysis on the Actual Conditions of Deaths due to Fires based on Annual Report on the cause of Death Statistics in Korea
Lee, Eui-Pyeong ;
Fire Science and Engineering, volume 20, issue 1, 2006, Pages 98~103
This paper analyzed deaths caused by fires using the Annual Report on the Cause of Death Statistics (based on vital registration) published by the Korea National Statistical Office. The number of fire deaths and the fire death rates of all deaths have started to decrease since the height in 1993. The younger groups have increasingly more fire deaths than the older groups. While children groups(age 10 and under) have decreased in their deaths caused by fires, the older groups (65 and over) tend to increase. Males are more likely to have a risk than females in all age groups. Fire death rates per 100,000 populations by age group suggest very high rates in the older groups. Although there are few changes in death rates caused by fires of all deaths, young children (age 4 and under) and older adults (age 75 and over) have a higher risk than any other age groups.
