In the events of a fire in the residential building, highly flammable polyurethane foam sofa produce toxic smokes. In this type of fire, the residents of the building can be gotten into the difficulties of evacuating from the fire places or may be to death due to a lot of hot toxic gases. In this study, CFD simulations were carried out to study the effects of the openings of stairwell on the fire characteristics of fire room and stairwell. Also, analysis of fire hazard based on the tenability limits of fire and FED(fractional effective dose) was performed to evaluate the life safety of the residents of the building. In the fire room, maximum temperature was about
, maximum CO concentration was about 4,740 ppm, and the time to incapacitation of residents in fire room was about t=144 s. In the stairwell, temperature and CO concentration in the condition of openings to be open were even lower than those in it to be closed. Time to the tenability limit with respect to smoke visibility in the stairwell with openings, which was open, was shorter than that of it without openings to be open. It has been shown from this study that opening the stairwell openings is able to decrease the fire hazards to the life safety in the multi-story residential building fire.

Kwon, Kyung-Ok ;
Fire Science and Engineering, volume 21, issue 3, 2007, Pages 56~60
The usage of MSDS (Material Safety Data Sheet) is increased world widely for the implementation of GHS and REACH. In order to know the accuracy of the data in MSDS the flash point of n-Decanol was measured by using a Tag closed tester, a Seta-flash closed tester, a Pensky-Martens closed tester and a Cleveland open tester in Japan and Korea, respectively. The test results of flash points of n-Decanol purchased different manufacturer were compared to the data of the references and MSDS. The flash points determined in Japan were similar to those in Korea but have shown much difference from those in MSDS and literatures. It is suggested that the results of flash points determined in this research have validity and manufacturers should be more careful when they make MSDS as well as for the classification of GHS and REACH.

Park, Bong-Rae ; Kong, Ha-Sung ;
Fire Science and Engineering, volume 21, issue 3, 2007, Pages 69~77
Our country automatic wet pipe sprinkler system of hydraulically designed system has not deviated from the pipe regulation process, therefore we face limitations when using an independent method to hydraulically designed system. Therefore. after reviewing a developed country's methods using the drainage-density concept, we found it necessary for our country to introduce the drainage-density concept. Currently, under the National Fire Safety Codes(NFSC), this does not solve the problem and the limitation of hydraulically designed system because different problems arise depending on where the head was installed. To make improvements, first, such as the developed country, overcome the difference by introducing the drainage-density concept to determine the amount of drainage. Second, by using diverse head caliber and decreasing the limits on the amounts of distribution, we can expect a leveling off of the drainage density. Third, using the increase of hydraulically designed system through the application of the rule to hydraulically designed system, finally, development to performance based fire protection design.
