A Study on Fire Data Analysis in Korea, Japan and USA(3) Deaths and Injuries Due to Fires
Lee Eui-Pyeong ;
Fire Science and Engineering, volume 19, issue 1, 2005, Pages 1~19
The following matters were confirmed through the analysis of casualties due to fires in Korea, Japan, and the U.S. in this paper. 1 Korean statistics are not the most detailed of the three countries about casualties due to fires, so we need to have detailed statistics of them on casualties more. 2. Korean deaths are the lowest by 10-11 people due to fires per one million of population. Those of Japan are 15-17 and about 12 people in the U.S.; decreased about 2/3 only for a quarter of a century. 3. Korean deaths are on the decrease about 1.5 people per 100 cases due to fires,3.5 in Japan and 0.2-0.3 in the U.S. Likewise, Korean injuries are on the decrease per 100 cases due to fires From 14.9 in 1977 to 5.1 in 2001 and 5.3 in 2002. In the U.S., the figure was 1.0-1.6. but after the year 1994, it was 1.2 or so. It tends to some increase to 2.6-2.8 in Japan. Therefore, when fires are happened, the death probability is the highest in Japan and 15 times higher than that of the U.S. The injury probability is the highest in Korea and 5 times higher than that of the U.S. 4. Fire deaths rate is the highest in the U.S. about
due to home fires (including apartments) among all deaths. Japan tends to decrease of
. Recently, in case of Korea. it is similar level to that of Japan. 5. Korean aged people of 65 years old and over exceeded by
in 2000 and entered an aging society, so It Is time to Investigate and take effect policies to reduce the death of the aged . Japan has ahead a super-aged society that exceeds
of the people over the age 65, and many of them die of fire. Consequently, Japan has taken effect policies to reduce deaths from 10 years or more than before. Therefore, it is a good proposal to analyze the policies of Japan deeply and study introduction of them.

Major petrochemical companies in the USA and the EU map out the strategies step-by-step hazard evaluation for the efficient risk management. They adopted the risk screening methods, such as Dow fire & explosion index, as a preliminary phase to execute detailed evaluation such as QRA (Quantitative Risk Assessment). In this study, The FEDI (Fire & Explosion Damage Index), which a kind of risk screening method proposed by Khan and Abbasi, was applied to the BTX plant in Korea. We showed that the FEDI can be effectively used to classify the hazard potential by comparison of the result from the FEDI and the result from QRA. And we showed that the characteristics and the quantities of chemical are the factors which have a largest effect on fire and explosion by executing relative sensitivity analysis of the FEDI. In conclusion, if the FEDI was applied as a preliminary phase of HAZOP, more efficient hazard evaluation can be possible.
A Study on Safety Policies Toward Aging Society

Fire Science and Engineering, volume 19, issue 1, 2005, Pages 29~45
Korean society became an 'aging society' in 2000 years with a population of 65 years and over occupying
of the whole population. And we expect that a population of 65 years and over will occupy
in 2019 years, so Korean society will enter into an 'aged society' Older adults can't react correctly and rapidly to the disaster due to the decline of the physical function, therefore victims of older adults due to the disaster will increase as much as aging proceeds. For reducing sacrifices of older adults due to the disaster, 1 suggest that the propulsion of the disaster service policy for disaster week people like older adults, the policy of minimizing casualties due to fires, reinforcement of fire resources and enlargement of disaster services in rural communities, offering information about disaster services and reinforcement of functions of public relations, making new connection systems (e.g. educating welfare and post officials as volunteer fire officials), supplement of fire fighters, and the policy of lightening fire equipments.

There were little available data of vehicular incendiary fires. We investigated fires by inflammable gasoline and papers. cloths in the interior and exterior of vehicles. Fires in the interior and exterior of vehicles were carried out under the several conditions by incendiary methods and vehicle's windows. We knew that dominant factor of combustion is direction of wind at that time in vehicle's fire. And we knew that the other mark of combustion pattern in vehicle's fire could be a clue for solving the problem in discerning the place to which we sotted fire between the general fire and arson.

Fire scenarios in a space
floor and 3.0m high were simulated by using computational fluid dynamics program (FDS 4.0.3) to investigate the effect of the combined operation of both sprinkler and vent systems, which are installed for cooling and blocking smoke which propagates beneath the ceiling of a horizontal corridor, on the temperature and smoke density of it. It was shown that the combined operation both sprinkler and vent systems was more effective than each operation for cooling and blocking smoke, the number of operating sprinklers was two because of corner effect of wall, and over-installed sprinklers deteriorated the effect of cooling and blocking smoke. This study showed that the case of two sprinklers and vent flow rate
in fire scenario was the most effective for cooling and blocking smoke. It was confirmed that the smoke downdrag occurs in operating sprinkler system, and the more smoke droplets produced by increasing fire size, the greater smoke downdrag occurred.

In this study effects of the natural wind and the forced smoke ejection by operating the exhaust fan are studied numerically to examine the flow characteristics of the smoke and heat generated from a fire on the platform of an underground subway station. Three different situations, including 1) the case with no natural wind and no exhaust fan operation, 2) the case with natural wind but no exhaust fan operation and 3) the case with no natural wind but exhaust fan operation, are considered for the numerical analyses. The numerical results show that the natural wind causes a rapid spread of the fire along the tunnel resulting in rapid spread of the smoke and heat over the platform which affects the escape. The operation of the exhaust fan also results in the rapid spread of smoke and heat over the platform, but the time required for reaching the safe escaping height of the smoke layer with the exhaust fan operation is much longer than that without the exhaust fan operation. The numerical results also show that the required capacity of the exhaust fan becomes larger when the effect of the natural wind is included.

The purpose of this paper is to judge the damage cause of instrument transformer(MOF; Metering Out Fit) installed in 22.9kV power receiving system. In the three-dimensional analysis of the restored MOF, the damage pattern progressed from inside to outside, there was no damaged part in the upside. The resistance of the carbonized middle part is roughly
and the exothermic temperature at inside is presumed as about
in the result of metallurgical structure analysis. The structure and the composition rate on metal surface by SEM is similar. In the result of FT-IR analysis, we can observe the absorbtion peak at
is small. The high exothermic peak showed at the center part of the coil in the result of DTA.
