  • Flammability of non-flame-retardant and flame-retardant materials was studied by using cone calorimeter Also, relations between the results obtained by using cone calorimeter and those obtained by the flammability test of japanese fire Service Law were examined. The results are as follows: 1) The ignition time of the molten specimens is relatively long, whereas the ignition time of the non-molten specimens is short. None of remarkable difference of the ignition time has been found between non-flame-retardant and flame-retardant materials specimens. 2) The peak heat release rates of flame-retardant materials are smaller than those of non-flame- retardant materials. 3) The carbon monoxide and smoke evolved from flame-retardant materials generate much more than those evolved from non-flame-retardant materials. 4) Even if flame-retardant materials are passed by the flammability test of Japanese Fire Service Law, they burn easily under external radiative heating condition.

  • 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.

  • The study is to analysis of fire protection regulations for the nuclear power plants (NPP) in the United States, Japan, the UAE (United Arab Emirates), and Korea with the intention of exporting NPP to the UAE. Fire protection regulations for NPP for these countries permit the fire protection design and facilities in accordance with the evaluation of the potential fire hazards. However, in Korea, the NPP is a part of power generation facilities in Korea fire protection law, and the atomic energy act classifies them as the reactor and related nuclear facilities. The fire protection law and atomic energy act are different to the criteria for the fire protection of NPP. To maintain the leading position as a nuclear exporting country, the performance-based fire hazard analysis should be reasonably incorporated in the design of the fire protection system. It was suggested that the integrated requirements of the fire protection for NPP should be incorporated to the construction article for the fire protection facilities specified in paragraph 2 of Act II, being classified into the special objects to be protected against fire, which requires a performance-based design in order to incorporate the specific requirements for NPP.

  • This study was conducted by survey and inspection of stair passage leading lights in shopping buildings which are more than 5 stories and have an underground parking lot located at Pyeongtaek-si and Seongnam-si. Number of shopping building for this study is 30 and of stair passage leading light inspected by two lights in each shopping building is 60. The result of this study is that the type of installed leading lights is LED(77%), and 60% of leading lights has problem such as no cleaning, scratch and discoloration, etc. The height of installed leading lights meets the fire law which is less than 1m from the floor. Visible condition of leading lights is good except some leading lights which have a little visible problem due to banner advertisement. 37% of standby power has flickered and went out. 93% of total leading lights meets the fire law which is more than 1lux from 0.5m distance, but cold cathode fluorescent lamps(CCFLs) have the problem which not meets proper brightness level based on fire law. In additional measurement result, zero lux of leading lights is 32%(from 1m distance), 68%(from 1.5m distance) and 98%(from 2m distance). Leading light is very important facility because it is eyes and guide when emergency. Therefore, proper fire facility operating function inspection and total detailed inspection are important to keep the good condition of leading light except simple visual check, and also improvement in law system of type approval, fire construction inspection and illumination level will be needed.

  • In this study, to assess the validity of scaling law which was based on the ventilation factor and utilized in fields of compartment fires, numerical simulations were conducted on full- and 2/5 reduced-scale compartment fires using FDS and simulation results were compared with the previously published experimental data. The numerical modeling used in this study was verified by comparing the predicted temperature at several points of the upper layer with the experiment data. Temperature and concentration distribution inside of compartments and velocity profile at door of compartment are analyzed to assess the validity of scaling law. Comparison between the predicted results on the full- and reduced-scale compartments shows good agreements on the inner compartment flow patterns, outflowing flame patterns from the compartments, and vertical temperature distributions.

  • For commercialization of hydrogen refuelling station (HRS), we need to reduce the clearance distance for jet fire in the real entities in the HRS. Thus, we revisited the current regulations of clearance distance for jet fire in the law. The law in korea has been set up by replica of japan, not by our own scientific basis. Recently, sandia lab developed Hydrogen Risk Assessment Model (HyRAM) tools and we simulated a series of circumstances such as 10 to 850 bar with several leak hole sizes. In 850 bar with 10 mm diameter hole leak cases, it shows $4,981kW/m^2$ at 12 m separation from leak source and $1,774kW/m^2$ at 17 m separation from leak source. In 850 bar with 1 mm diameter leak hole, it shows $0.102kW/m^2$ at 12 m separation and $0.044kW/m^2$ at 17 m separation. Current law may be acceptable with 1 mm hole size with 850 bar.

  • The purpose of this study is to suggest architectural planning guideline for the improvement of the evacuation environment in a ward. To suggest of guideline, the problem of irrational domestic criteria is searched according to compare National fire code (NFPA101, Life safety code) with Korea building law. This study includes stairs, corridors and exit door etc. but excludes fire facilities. To verify effectiveness of suggested guideline, egress simulation is run that based on databases according to literature survey. The results of this study could be summarized as follow: Suggested guidelines are subdivision(fire partition), evacuation by elevator, secure useful waiting space of elevator hall and smokeproof enclosures, the corridor is divided by fire or smoke barriers corridor from hazardous room, only wheeled items are arranged in corridors of a ward story. The result of computer simulation for suggested guidelines verify that egress time can be decreased 20% or above.
