Recently, a building fire has occurred due to various influences. Accordingly, we are developing an public safety & security unmanned aerial vehicle for fire prevention and initial response to fire. The public safety & security unmanned aerial vehicle is used to grasp the traffic route to enter the fire engine in the event of a fire in a dense structure and to determine the scale of the fire and the area of danger of collapse around the fire site. In this study, an environmental test of the public safety & security unmanned aerial vehicle's heat resistance was performed in an environment simulating a fire scene.

This paper proposed that the method be searched for optimal route of evacuation by algorithm using potential field in specific situation, fire. When robot met an obstacle to be indicated it to ignition point, the installed sensor could be detected the point in restricted area. In according as the data of a fire detection sensor and a sensor complex in a building, the information was transmitted to server which computed optimal route of evacuation by algorithm using potential field. After that, it was able to blow a siren and mark the safe-path with using wireless device such as smart-phone. It was confirmed that the proposed method in functional test, fire emergency evacuation algorithm using potential field, was advanced in circumstance of simulation.

When a fire happens in builds or apartments, peoples are tend to be caught in dangerous situations owing to the failure of searching escape route to the outside. In this work, an efficient fire detection and alarm system which makes it possible for the escapers to take adequate actions is proposed. The proposed system consists of two parts. One is fire detection modules which are located at each compartments in a building. The other is fire warning modules equipped with portable flashes having ability of visual/voice warning. Fire detection information is transmitted between each modules wirelessly. In this work, an efficient communication protocol for sensor network-based fire detection system is proposed and its feasibility is verified by practical experiments using MANGO ZDK Development tools

Korean apartment buildings have been manhattanized and enlarged, but it caused increase of fire accidents. Fire accidents such as Uijeongbu apartment fire(2015), and Ssangmoon apartment fire(2016) caused many deads because of a lack of emergency exit route awareness. Follow to advanced research, conducted suervey on fire safety awareness. On this study, it will present the basic data based on the result of the survey to secure the life.

Length of staircase get longer and evacuation load get heavier in proportion to the building height. Therefore evacuation time could be considered proportional to square of building height. While smoke spreads vertically so rapidly, evacuation speed is too slow, therefore the reasonable measure for the safe of egress route is urgent. Existing pressurizing smoke control system of vertical exit route is seriously limited in function under the stack effect in winter. Stack effect in winter could be overcome with the methods of opening the staircase outward or letting airflow be free between staircase and outside.

In this study, an algorithm to predict evacuation routes in support of shipboard lifesaving activities is presented. As the first step of algorithm development, the feasibility and necessity of an evacuation route prediction algorithm are shown numerically. The proposed algorithm can be explained in brief as follows. This system continuously obtains and analyzes passenger movement data from the ship's monitoring system during non-disaster conditions. In case of a disaster, evacuation route prediction information is derived using the previously acquired data and a prediction tool, with the results provided to rescuers to minimize casualties. In this study, evacuation-related data obtained through fire evacuation trials was filtered and analyzed using a statistical method. In a simulation using the conventional evacuation prediction tool, it was found that reliable prediction results were obtained only in the SN1 trial because of the conceptual and structural nature of the tool itself. In order to verify the validity of the algorithm proposed in this study, an industrial engineering tool was adapted for evacuation characteristics prediction. When the proposed algorithm was implemented, the predicted values for average evacuation time and route were very similar to the measured values with error ranges of 0.6-6.9 % and 0.6-3.6 %, respectively. In the future, development of a high-performance evacuation route prediction algorithm is planned based on shipboard data monitoring and analysis.

In this research, in order to more concretely define the concept of the previously vaguely defined fire road, the authors propose new terminology called disaster prevention routes. These are defined as predefined access routes for the quick response to disaster areas. For this, the authors suggest selection techniques for disaster prevention routes considering characteristics of fire trucks and selected areas. The paper also includes legally-based ideas for the executive departments with exclusive responsibility for continuous management and supervision of disaster response. In addition, a case study is performed with a virtual scenario including the outbreak of fire in one borough of Seoul. This case study shows that the damage can be decreased by prompt access of fire trucks. The establishment of predefined access routes to disaster areas can help to protect citizens with more rapid response by emergency crews. Indirect benefits also include reduced congestion of roads through the prohibition of parking and stopping on the chosen roads.

The aim of the study intends to investigate the recognition of fire safety of traditional market employee in Masan city and to provide the base data for the fire safety. The results of the study are as follows. The traditional market employee have high interest in fire safety and recognize that the possibility of fire is high in market. The traditional market employee of 46.0% takes fire safety education and preferred self-government merchant association in market as education place. This study shows that the traditional market employee of 41.5% recognize a fire escape route. In order to prevent the fire of traditional market, the strong activity of market fire staff and the periodic fire inspection of fire department are recommended.

When caught in a fire inside a building or a tunnel the generated smoke is the main cause of the bad visibility, which makes it difficult for a person to find escape route. Therefore of the fire simulation it is required to visualize the simulated results of smoke realistically form a viewpoint of a person caught in a fire. In the present study, developed is a CFD post-processor which can visualize the object through smoke from the results of CFD fire simulation. Examples of some applications of the program are shown in the paper.
