  • This study analyzed the effects influencing the elderly's knowledge on fire safety and practices of fire safety accident prevention after developing a Fire Safety Education Program for the elderly. The program was developed through verification using some experts and a pilot study after selecting the objective, goals, contents, and teaching & learning methods of the program based on the basic survey and literature review. The effects of the program were verified by conducting some non-equivalent control group pre- and post-tests after dividing the targets into the experimental group (the Fire Safety Education Program for the elderly was implemented) and control group (only printed hand-outs were given) among 48 elderly people no younger than 65 years of age. A paired t-test revealed some statistically significant differences between the scores of the pre- and post-tests of the experimental and control groups. ANCOVA found that the effects of the program were significantly higher than those of the printed hand-outs because the post-test scores of the experimental group were higher than those of the control group.

  • AU(A plus U-shaped) composite beam was developed for reducing the story height in the residential buildings, and saving the cosrtuction cost of floor structures. Structural performance and economic feasibility of the composite beam have been sufficiently approved through the structural experiments and the analytical studies. Fire safety for the practical application of the composite beam has also been verified through the fire resistance tests and the heat transfer analyses. In this study 2-points bending tests were performed on the four specimens already tested for fire resistance to evaluate the residual bending strength of AU composite beam after fire accident. The same bending test was performed on the one fresh specimen having the same section and span of the specimens for practically comparative study.

  • Today's building and fire prevention codes are mostly prescriptive. Prescriptive codes are based on major fires in earlier years that created a need for specific building provision. These codes provide a minimum level of safety. As the general and engineering uses of computers have increased over the years, so has use of computers in the fire protection engineering. This has allowed fire protection engineers to develop alternative approaches to solve today's fire protection problems or to evaluate the performance of a specific fire safety goal. A performance based approach to building and fire codes involves the following: 1) identifying specific goals, such as, safely getting out of the building in 10 minutes, 2) obtain conceptual approval from authorities, 3) define performance level, 4) develop design solutions and identify tools such as, fire tests, models, or methods, to demonstrate that a design will meet the fire protection objective 5) test solutions, 6) present test method and results to the authorities. Some people in the fire protection community consider this to be nothing more than an intellectual exercise, while the others view it as a way to reduce expenses on large project$^4$ Others in fire protection community view this as a way to refine the design process to design fire protection systems to better protect the fire hazards. This paper will focus on application of these tools, specifically computer fire models, to actual cases such as: design of a smoke control system heat transfer analysis and egress of building occupants during potential fires.

  • Purpose: The purpose of the study is to reduce the fire of the same type by analyzing the form which is mainly generated based on the result of the fire investigation through the experiment to reproduce, since the candle fire is repeated every year with the same type. Methods: For the analysis of candle flame, 4 kinds of methods such as acrylic recharge test, FOMEX acrylic recharge test, general combustible recharge test, and natural fire extinguishing test of candle were conducted. Results: It was confirmed that continuous burning is difficult to be achieved without contact of combustible materials around. Conclusion: In order to prevent a candle fire, it is important to check the safety of the surrounding area. It is also considered to introduce safety regulations such as finishing with a fireproof material such as a silver foil at the terminal end.

  • This study aims to examine the risk of electrical fire in places where electric heat wires are used. In general, the use of electric heating wires is becoming more common and prevalent in a bid to prevent increasing damage caused by freezing and bursting in residential water pipes, factory pipes and irrigation pipes in vinyl greenhouse and a variety of heat wire products are available in market with legal safety requirements imposed on them. However, the widespread use of anti-freezing burst heat wire products has caused increasing incidents of fire, which often fail to be incorporated into statistics due to quick onsite extinguishing and insignificant damage although damage is gradually on the rise. Against this backdrop, this study aims to look into the possibility of ignition caused by electric heat wires and the mechanism of how it turns into catching fire through overheat and short circuit tests for anti-freezing burst electrical heat wires (hereinafter called the 'heat wire') and expects to serve as the basis for further observations and analyses on the cause of fire and the process of ignition in a scientific manner.

  • This paper recognizes the risk of ignition of air fryer (machine that can cook fried dishes with hot air without oil) that is far exceeding the sales rate of microwave ovens, which is necessary to modern household kitchen, and identifies fire risk through the operation principle of the process of heat transfer, and the main structure of the machine. The fire test that we conducted is to observe the risk of ignition of the machine due to the damage to the safety system and the possibility of igniting oil paper along with food, to experiment with the possibility of ignition due to blockage of the exhaust due to obstacles, and accumulation of oil stains on the hot wire, and to present the method of fire control and devise countermeasures.

  • The marine industry is rapidly developing as a result of the increase in various needs in the marine environment. In addition, accidents involving ship fires and explosions and the resulting casualties are increasing. Generally, manpower and safety problems exist in fire fighting. A fire fighter in the form of an autonomous surface robot would be ideal for marine fire safety, because it has no manpower and safety problems. Therefore, an autonomous surface robot with the abilities of fire recognition and tracking, nozzle selection, position and attitude control, and fire fighting was developed and is discussed in this paper. The test and evaluation results of this robot showed the possibility of real-size applications and the need for additional studies.

  • This study compared the fire safety standards for windows of Korea, the U.S. and Japan to prevent fire expansion through exterior wall openings, and conducted experiments using PVC and aluminum window frames, which are widely used in Korea.The experiment is KS F 2845 which combines frames of the same thickness and area with single-window form and 1 hour fire resistance glass with 8T thickness. Experiments showed that the PVC window was about 9 minutes and the aluminum window was about 26 minutes. However, in Korea, there are no test standards for windows installed at the opening of the exterior wall. In addition, fire safety standards for windows shall be established along with the designation of fire prevention zones.
