Fire Science and Engineering, volume 19, issue 3, 2005, Pages 1~12
June 1, 2004, National Emergency Management Agency was established, and one of its aims is to reduce the percentage of accident occurrence and damage scale to that of developed countries in 10 years. In this paper, Korea is compared with Japan in the view of actual conditions of accident occurrence in order to compare Korea with developed countries. In the case .of Korea, traffic accidents, fire accidents, careless accidents, drowning accidents, climbing accidents occur frequently. Decreasing these accidents is a major target to reduce the accident occurrence. Also, home accidents of babies and elders who are unable to avoid dangers are frequent. Studies focusing on those related accidents are required.

An experimental study is presented for extinguishing characteristics of liquid fuel fire by water mist containing sodium acetate trihydrate. To evaluate the extinguishing performance of water mist containing an additive, the evaporation characteristics of a water droplet on a heated surface was examined. The evaporation process was recorded by a charge-coupled-device camera. Also, small-scale extinguishing tests were conducted for n-heptane pool fire in ventilated space to measure flame temperature variation. The average evaporation rate of a water droplet containing an additive was lower than that of a pure water droplet at a given surface temperature due to the precipitation of salt in the liquid-film and change of surface tension. In case of using an additive, the flame temperature was lower than that of pure water at a given discharge pressure and it was because the momentum of a water droplet containing an additive was increased reducing flame size. And also dissociated metal atoms, sodium, were reacted as a scavenger of the major radical species
which were generated for combustion process. Moreover, at a high pressure of 4MPa, the fire was extinguished through blowing effect as well as primary extinguishing mechanisms.

This paper evaluates the fire safety level of eight pump rooms in the nuclear power plant using a fire model, CFAST We estimate the Conditional Core Damage Probability (CCDP) of each room based on the analyzed results of CFAST Eight rooms located on the primary auxiliary building of the nuclear power plant are high pressure safety injection pump room A/B, low pressure safety injection pump room Am. containment sprdy pump room A/B, and motor-driven auxiliary feed water pump room A/B. The upper layer gas temperature of each room is estimated and the integrity of cable is reviewed. Based on the results, the integrity of the cable located at the upper part of compartment is maintained without thermal damage. The Conditional Core Damage Probability Is reduced to half of the old values. Accordingly, the fire safety assessment for eight pump rooms using the fire model will be capable of reducing the uncertainty and to develop a more realistic model.

The goal of this study is establishment of egress parameters and algorithm for estimation of total egress time in hospitals. Therefore, egress parameters should be measured and analyzed via the experiment at many hospitals. In this study, 4 general hospitals were experimented and egress parameters were measured, the comparison between experimental results and estimated total egress time were carried out. The algorithm for estimation of total egress time can be applied to other hospitals.

When a fire breaks out in a high-rise building, the firefighters must swiftly arrive at fire area with his equipments ready and use the emergency elevator for a more effective operation. In spite of the legal regulations about the emergency elevator, the ones currently installed show various problems and require improvements related to the fire fighting. This research work in to review the regulations on emergency elevator in Korea and other nations, and to conduct a questionnaire survey on the operation of emergency elevators to the fire officer, and finally to provide new standard and operation methods.
A Study on the Flame Propagation Velocity of Methyl Alcohol

Fire Science and Engineering, volume 19, issue 3, 2005, Pages 44~51
The flame propagation velocity and the flame arrival time of methyl alcohol, which is widely used as a material of paint industry and organic synthesis, d mixing solvent, and an analytical reagent, were examined at different temperatures and concentrations. It was found that the smaller the vessel size, the easier and faster the combustion. The maximum combustion velocity was 200 cm/sec in the small vessel at
. The flame arrival time was determined to be longer with larger vessels. and shorter with higher concentrations.

It has been known that there is not the general design method for water mist system because the fire extinguishing mechanisms are dependent on both spray characteristics and a fire compartment. It is therefore rational that a general performance-evaluation guideline does not exist. The present work suggests the performance-evaluation guideline for water mist system applied to the power transformer room based upon the investigation and analysis of fire accidents and the similar guideline.

Experimental measurements of flames and the product properties were performed for small kerosene pool fires. which is widely used as a fire source of laboratory scale experiments with scaling modeling. The flame length and flickering frequency were investigated for the flame structures, and compared with the theory. Three measurement methods were introduced to clarify the smoke characteristics, i.e. various gas concentrations, smoke density and thermophoretic sampling with transmission electron microscopy (TEM). The yield of carbon dioxide and the consumption of oxygen were proportional to the heat release rate of pool fires, but there is no trend on carbon monoxide emission. Smoke density of turbulent flames was exponentially increased with the heat release rate. The morphology of the soot particle was investigated to address the degree of soot maturing. The results show that the similar smoke morphology between an inverse jet flame and a pool fire exists despite of different combustion controlling mechanisms.

In order to decrease the area damaged by forest fires and to prevent the occurrence of forest fires, we are making an effort to improve prevention measures for forest fires. The objective of this study is developing the forest fire occurrence probability model by means of forest site characteristics such as soil type, topography, soil texture, slope, and drainage and forest fire sites. Conditional probability analysis and GIS were used in developing the forest fire occurrence probability model that was used in the classification of forest fire occurrence risk regions.

The heat of combustion of polymer materials is an important fire characteristics, which can be used with other fire parameter to predict the potential fire hazard in the polymer handling process. The aim of this study is to predict the heat of combustion for polymers which used in the building interior materials. By using the literature data and multiple regression, the new equation for predicting the heat of combustion of polymers is proposed. The A.A.p.E.(average absolute percent error) and the A.A.D.(average absolute deviation) of the reported and the calculated heat of combustion by means of the oxygen consumption calorimeter and the stoichiometric coefficient were 4.46 and 1.09, and the correlation coefficient was 0.972. The values calculated by the proposed equations were in good agreement with the literature data. Therefore, it is expected that this proposed equations will support the use of the research for other polymer materials.
