The purpose of this study is to identify the fire danger of the electric radiant heating system and check the way how to use it and the problems that could be possible through a actual case. We carry out an experiment to identify the possibility of the fire in the similar condition of the actual fire case. The results of this study are as follows. It is a possible condition to fire if the air blast of the electric radiant heating system is blocked by some combustible materials such as plastic bags continuously. A temperature sensor and a residual current device are necessary to disconnect the power source. It is also necessary to attach a notice in front of the electric radiant hearing system that shows users the fire danger to forbid the possible fire. Fires could be happened by internal defects of the electronic products. However, we can also find many external reasons to happen fires. Therefore, we need to check all reasons to make fires in the scene of a fire.

The study seeks to cooperate with the investigation of a fire investigation based on public-private partnership. Fire protection systems provide a wide variety of viewpoints from the perspectives of design, construction, management, maintenance, maintenance and maintenance systems at a particular point in time, construction, management, and maintenance systems. What is controversial is that there are illegal activities such as illegal activities of the Patent Office, misconduct of construction work and unreasonable construction of construction works.As a theoretical framework, the present study identified the four key elements of a successful disaster response system : responsiveness, control, professionalism, and bias.

화재 발생에 따른 화재조사 시 배전반이나 분전반의 완전 소락에 따른 전기화재 원인규명의 기본적이고도 중요한 증거 소멸로 원인불명 율이 점차 높아가고 있는 실정이다. 공장이나 창고에서 전기화재를 가장한 수 배전반 화재를 시도할 경우 그 증거를 찾기 어렵다. 또한, 수 배전반이 위치한 곳에 사람이 상주하지 않는 곳이 많으며 초기 소화가 원활히 이루어지지 않을 경우 막대한 재산 피해와 통신의 대혼란을 가져올 소지가 다분히 존재하고 있다. 따라서, 수 배전반 및 분전반의 화재로부터 보호하기 위해서는 신뢰성과 안전성이 확보된 자동소화 시스템의 도입이 필요하다.

2018년 8월 21일 15시 40분경 발생한 전자공장화재로 9명이 사망하고 6명이 부상을 입는 인명피해가 발생하였다. 이 논문에서는 이 전자공장화재에서 다수 사상자가 발생한 원인을 화재조사결과 등을 토대로 구체적으로 분석하고 있다. 다수 사상자가 발생한 주요 원인은 자동화재탐지설비 기능 정지, 비상방송시설 기능 정지, 4층 천장의 우레탄폼 착화로 인한 급격한 화재 확산, 화재발견 직후 정전 발생, 스프링클러설비 미작동, 화재신고 지연, 소방시설관리 업체의 소방시설관리 부실 등으로 분석하였다.

In this paper, the elemental components and improving purpose in advanced safety management system are reviewed to cope with a railway fire accident. And a considering procedure(V-cycle) of long-term plan for railway fire safety improvement is proposed. For the purpose of preventing recurrence of accident, items which have to be considered in the course of accident investigation and cause analysis are presented according to the stage of investigation activity.

PURPOSES : The occurrence of unexpected disasters, including fire events, increases as the road network becomes complicated and traffic volume increases. When a fire event occurs on and under bridges, the damage extensively influences direct damage to structures, vehicles, and human life and secondary socioeconomic issues owing to traffic blockage. This study investigated potential fire-hazard risks on bridges of the Korean national route road. METHODS : The investigation was conducted using field investigation and analysis with satellite pictures and road views from commercial websites and the Bridge Management System (BMS). From the filed investigation, various potential fire resources were identified. The satellite pictures and road views were helpful in measuring and recognizing conditions underneath bridges, stowage areas, etc. RESULTS : There are various potential fire resources underneath bridges such as piled agricultural products, parked petroleum tanks, construction equipment, and attached high-voltage cables. A total of 94.6% of bridges have underneath clearances of less than 15 m. A bridge underneath volume that can stow a potential fire hazard resource was $7,332m^3$ on average, and most bridges have about $4,000m^3$ of space. Based on the BMS data, the amounts of PSC and steel girders were 29% and 25%, respectively. CONCLUSIONS : It was found that the amount of stowed potential fire hazard resources was proportional to the underneath space of bridges. Most bridges have less than 15 m of vertical clearance that can be considered as a critical value for a bridge fire. The fire risk investigation results should be helpful for developing bridge fire-protection tools.

Approximately 20% of the total fire is electrical fire, and electrical energy is a potential source of heat. Large-scale fault currents that occur during a line ground fault flow into electric utility poles, electric power equipment, or electric appliances of the customer, and cause simultaneous electrical fire. In this paper, we investigated the possibility of fire through the change of fault current flowing in faulty and sound feeder in case of 1 line ground fault in 22.9 kV distribution line. We propose a fire investigation analysis method for simultaneous multiple electrical fire such as evidence analysis method, and fault current occurrence confirmation method in case of fire accident by analyzing the fault current occurring in the ground fault in the distribution line using EMTP, electric power system analysis program.

화재조사 결과를 토대로 고양종합터미널 건물 화재 시 소방시설 작동 실태를 분석하였다. 분석결과를 요약하면 다음과 같다. 첫째, 천장 우레탄폼에 불이 붙은 직후에 옥내소화전을 이용하여 진화할 수 있음에도 시도하지 않았다. 둘째, 지하1층 대수선공사 공간은 스프링클러 알람밸브를 잠가놓아 작동하지 않았지만, 지하2층과 지상1층, 지상2층, 지상3층은 스프링클러가 작동하여 지하1층 대수선공사 공간 이외의 층으로의 화재확산을 저지하였다. 셋째, 피난유도등은 정상 작동하였지만, 터미널 2층 대합실에서 승차장 쪽으로 통하는 출구(비상구)에 피난구유도등이 설치되어 있지 않아 터미널 2층에서 다수의 사상자가 발생하게 하는데 영향을 미쳤다. 넷째, 화재수신기에서 제연설비 배기 팬 제어반에 전기신호를 보냈지만 배기 팬의 제어반에서 수동으로 취급하여 터미널 2층 제연설비 배기 팬이 작동하지 않았다.
