  • The interior materials of the urban subway car in operation are now being changed to new materials that meet the latest law in effect, the fire safety criteria of the urban railway vehicle. It was well known fact that the composite materials, that were applied to last subway car, were weak on the fire. Contrary to this materials, materials in work have good resistance to the fire. On the paper, To investigate the difference of fire safety level on the subway car, cone calorimeter was used to measure the heat release rate and total heat released according to the ISO 5660. A high radiative heat flux of 50kW/m2 was used to burn out all materials and to simulate the condition of fully developed fire case in the tests.

  • By rearing private experts to design hazardous facilities, Safety property is obstained. So it is necessary to limit within the designer of hazardous materials facilities who has some degree skill. After permission progress about the inspection of the design ascertain whether it is safety property Mayor/Do governor permits within the laws and their qualification. Accordingly, Korea Fire Equipment Inspection Corporation be come specialization about the design, inspection of construction completion. A inquire purpose of Fire Service Act be considered fitness. Subject by which the Korea Fire Equipment Inspection Corporation is entrusted, subject by which the a non-probit corporation in The Civil Law be possible to entrusted in separate. In this case, because of the level of one's technique and facilities are important, to limit as a nonprobit corporation in The Civil Law give rise to trouble. Consequently; established a business corporation, which the level of one's technique and facilities, in accordance with The Commercial Law can assign inspection of construction completion. The contents of the Fire Services Act is caused by the historic growth of hazardous facilities's safety management. Because we decide on a course about completed inspection of hazardous substance, it is needed that adjust the task performed by a corporation of the exert skill and the duty performed by the task that a authorized corporation on the civil law or the commercial law To adjust the duty, the Fire Service Act, that is suitable to the purpose and principle, should constitute a measure of the duty. With the object of insure the safety of the hazardous substance, when the fire survice act establish a corporation of the expert skill. There is the will of lawmakers that need organization to have the power of the professional technology. The state excise the will that insure the safety of hazardous materials facilities on the basis of the professional technology and facilities, and construct to establish a corporation of the expert skill. Therefore as concentrate on the technology to need to insure the safety of the facilities of hazardous substance to be suitable on the purpose of laws and take responsibility and reports to a corporation of the expert skill. The task to be given to the state will be done.

  • The flash point is one of the most significant combustion properties of flammable liquids in industrial processes when evaluation process safety, In this paper, Cleveland open cup tester is used to measure the flash points for the two binary systems (n-propanol + formic acid and acetic acid + propionic acid). The measured flash points were compared with the values calculated by the Raoult's law and the optimization method using van Laar and Wilson equations. The calculated values based on the optimization method were found to be better than those based on the Raoult's law.

  • The system of The Volunteer Fire Brigade is the Civil autonomic one which was set up from The Chosun Dynasty and has been active. Having suffered from several dificulties from Japanese control in the Chosun Dynasty, The Volunteer Fire Brigade was established by the enactment 1958 Fire Law and we have had it up to this time. The Volunteer Fire brigade played an important role in the period of the past Fire fighting personnel and equipment which we did not have. It has carried out the assistance of the Fire extinction, the early extinction of a fire in the rural region, the extinction of the forest fire, and lots of social volunteering actions etc. but, today's Fire fighting system has made the surprising developments, such as the improvement of national economic power, the increase of knowledge about the safety of the people, the openness of The Fire Fighting Department of Korea. I will try to check out the role of The Volunteer Fire Brigade which filled up the lacking part the fire fighting in the past and make the measures which can activate in these days, looking for the new field of the movement.

  • In the recent years, the high strength concrete has increasingly been used according to extending market of tall buildings. However, Ministry of Land, transport and Maritime Affairs was established by law with an alternative plan after June 2008 because of the weakness of high strength concrete accompanied spalling phenomena in fire. The mix design of concrete has to properly meet standards which are the spalling resistance of concrete and limited temperature of steel reinforcement. The fire proof concrete mixed fiber has widely been used to meet spalling safety on the many construction sites, the most researches about the fire proof concrete mixed fiber had being carried out focused on fire resistance, compressive strength and cast in place of concrete. But the most important thing is column shortening used the fire proof concrete within the vertical members. In this paper, the fire proof concrete filled spalling safety standards was experimented by required material when the column shortening is revised between normal concrete and fire proof concrete mixed fiber and then the results have done a comparative analysis. Also, The paper aimed to indicate a basic data for revision of column shortening of fire proof concrete.

  • Recently, evacuation safety of a resident of building become the major concern, because building has been higher and more complicated. Buildings in Korea should install the natural smoke venting or mechanical smoke exhaust equipment according to the building law. The smoke control is the most important to guarantee the evacuation safety. This study evaluate the influence to the height and temperature of smoke layer by enlarging smoke vent size and operating sprinkler system using CFAST (Version 6). Smoke venting size is larger, the effect to height and temperature of smoke layer is increased in below 5 MW fire. But, the correlation of these is decreased in above 10 MW fire. The case that opened smoke vent and sprinklered are applied, life safety criteria are satisfied regardless of fire size. After design the fire scenario according to the service and size of building. Install the smoke vent suitable for the fire size and verify that by experiment or simulation.

  • This research deals with the combustion experiment of pine trees, which are the most representative species in Korea. Experimental data are compared with theoretical ones using Fire Simulation Program(FDS). It is considered that horizontal/vertical temperature distribution and radiant heat influence on adjacent areas in fire scenes. The linear function for separation distance to temperature was drawn by applying Stefan-Boltzmann's law; $y=112.13133{\times}({\sigma}T^4)^{-0.52916}$ for calculating the separation distance. In combustion experiment, the radiant heat came to $1.4{\sim}1.5kW/m^2$ in case of the separation distance by one meter. The numerical values mean that human body show the critical level of pain after one minute without a protective equipment.

  • Recently, due to fires in high-rise residential and commercial buildings and apartments in Ulsan and Busan, the issue of evacuation safety in the event of a building fire is being closely watched. In the evacuation safety design for these building fires, it is important to secure evacuation routes considering the spatial characteristics of the building or the characteristics of the occupants and to take measures to protect the evacuation routes in order to ensure the safety of the occupants in the event of a fire. Although simulation is mainly used in Korea to assess the safety of evacuation, there is a big difference in that the Building Standards Act provides tools that can be calculated more than simulation in neighboring Japan. In addition to the evaluation method, which is called the "Building Law Assessment Methods" in Japan, the research team considered that it is important to know the process of evaluation in future domestic research, and investigated the contents of the evaluation process and wanted to apply it first to domestic buildings in the future.
