Korea Electrical Safety Cooperation(KESCO) have provided the electrical safety speed-call service from 2007 year. Purpose of the service is to reduce discomfort of electricity use and to prevent electrical accident like as electrical fire and shock accident by providing emergency treatment service on fault of the residential electrical facilities notified in the specific house like as a lower-income group and a social welfare facility. But efficiency and economic evaluation of the electrical safety speed-call service is impossible because analysis on the quantitative effect of the service is difficult. This paper presents cost-benefit analysis method and result of the electrical safety speed-call service. The presented cost-benefit analysis method has a two-step process: the first step is to measure quantitative electrical fire prevention effect of the service by using electrical accident statistics and developing outcome analysis logic model of the service effect, and the second step is to analysis cost-benefit(B/C)of the service by calculating quantitative benefit analysis on the measured quantitative electrical fire prevention effect. The results showed that cost-benefit(B/C)of the electrical safety speed-call service is over 4 after 2010 year.

Revising the Occupational Safety and Health Act led to enacting and revising related laws and systems, such as placing fire observers in hot workplaces. However, the operating standards in such cases are still ambiguous. Although fire accidents occur through multiple and multi-step factors, the hazards of fire accidents have been identified in this study as individual rather than interrelated factors. The aim has been to identify multiple factors of accidents, outlining fire and explosion accidents that recently occurred in the domestic manufacturing industry. First, major keywords were extracted through text mining. Then representative accident types were derived by combining the main keywords through the co-word network analysis to identify the hazards and their relationships. The representative fire accidents were identified as six types, and their major hazards were then addressed for improving safety measures using the identification of hazards in the "Risk Assessment" tool. It is found that various safety measures, such as professional fire observers' training and clear placement standards, are needed. This study will provide useful basic data for revising practical laws and guidelines for fire accident prevention, system supplementation, safety policy establishment, and future related research.

Identification of the cause of electrically related fire accident may be approached either by studying accident related electric properties or by investigating power instruments at the site of the accident. In the present paper, the former approach is taken especially on investigating the consequences of excessive current induced by electric short circuiting of high power instruments which is reported as the primary cause electricity related fire accidents. In order to provide reliability of the identification method, microscopic photograph's are taken for the cross sections of the electric wires after being exposed to over current and heated by external means, respectively The results are consequently compared and analysed.

This Paper introduced a proper time evaluation for railway emergency response staffs using the Therblig Analysis. We defines what Activities the emergency response staffs should take when the fire occurs on the railway. This has been possible through the development of the scenario that is focused on the fire accident and it also has been driven to minimize the spread and damage of the accident. Gilbreth's Therblig Analysis has been used here to derive the reasonable time that would take for the emergency response staffs to respond to the fire accident on the railway system. We developed Emergency Response Scenario against Accidents and defined the Activity of the main Action for Emergency Response staffs.

The study analyses secondary damage of surrounding facilities from the fire accident by Unloading of LPG Bulk Lorry. Potential risk and extent of damage from jet flame and radiation heat is estimated with PHAST-RISK v6.7 program of DNV. According to above study, supplies can predict the damage range from gas release by Unloading, and be able to respond quickly.

According to ' Monthly report of train accidents and incidents ' of KNR, 95 numbers of rolling stock fire accidents/incidents had happened during last five years(from 1999 to 2003). Among them, there have happened only one injured accident which happened at Whamyung station in 1999. But it is necessary to consider a countermeasure for fire accidents/incidents, because they have big risk which might produce a large scale damage and lots of injured persons as the Taegu subway fire accident last year. This paper analyzes the rolling stock fire accidents/incidents which have happened during last five years in KNR, and suggests their countermeasures.

21C, Multiplex Cinema Theater is made from movie industry developed and become a place where we can spend our free time and consuming. But, theater users, who are many and unspecified persons, are short of information on the Multiplex Cinema Theater, so that they may be injured or killed at the occurrence of fire accident. Particularly, Multiplex Cinema Theater is a place that underground space or top floor in highrise building had many people in theaters. However, this problem is difficult to solve that to protect human being and properties at the occurrence of fire accident in the Multiplex Cinema Theater, In order to overcome such problems, Multiplex Cinema Theater need fire protection solutions facilities concerning particulars to pay attention to the safety on a fire and evacuation. This study analysed Multiplex Cinema Theater concept and computer simulation for risk point.

The consequence analysis for jet and flash fire accidents by the continuous release of butane vapor was performed and effects of process variables on consequences were analyzed in standard conditions. For the continuous release (87.8 kg/s) of butane vapor at 8m elevated height in the debutanizing process of the naphtha cracking plant operating at 877 kPa, 346.75 K, we found that for the jet fire accident, shape and size of the flame could be predicted and thermal radiation estimated by API model at 200m distance from release point was 1.5kW/$m^2$, and that for the flash fire accident, effect range was 11.2~120.2m. Also, simulation results showed that effects of operating pressures on consequences were larger than those of operating temperatures and results of accidents were increased with increasing operating pressures. At this time, effects of operating pressures on XUFL were smaller(about 1/10) than those on XLFL for the flash fire accident.
