  • When a fire breaks out in a distribution center, it causes a lot of damage. And the most casualties are caused by Fire accidents. Therefore, training for fire prevention should be mandatory at the distribution center. Also, the contents of education should be different in room temperature warehouses and low temperature warehouses. Fire education in low-temperature warehouses should be more emphasized. This is because many fires occur in low-temperature warehouses. In this study, a study was conducted to determine the important order of training hours and contents for fire prevention education according to the type of distribution center. The importance of time and content for safety education in all types of warehouses did not differ significantly. It was first decided that safety prevention training should be conducted periodically in all types of warehouses

  • Maritime accidents caused by a ship include collisions, sinking, stranding and fire etc. This study is intending to consider fire accidents among such diverse marine accidents. It is much likely that various sorts of fires break out because crews are living in a narrow space for long periods of time consequent on the ship's characteristic of sailing on the sea. This study carried out a simulation through the special program for fire analysis - FDS (Fire Dynamics Simulator) in order to find the effective evacuation time, i.e. life survival time. Particularly, this study did comparative analysis of the influence on the survival of cadets based on the collected simulation data by fire size and sort. As a result of the analysis, It was analyzed the Evacuation Allowable Limit Temperature $60^{\circ}C$ and resulted that there is no influence in evacuation by temperature. In case of visibility analysis, it reached to 5m which is the Evacuation Allowable Limit at 117 seconds under the condition of wood fire in 1MW. When there is Kerosene in 1MW, it took 92.4 seconds to reach by 5m which is the Evacuation Allowable Limit. Theoretical evacuation time for the non-tilted ship was 118.8 seconds in 1MW sized fire so it is shown that the most passengers are met the evacuation safety in case of wood fire. However, the majority of passengers could not be ensured the evacuation safety in Kerosene case.

  • Fire accidents in buildings are reported more frequently nowadays. Existing building fire accidents can lead to large-scale accidents as damage to human and physical resources increases over time, so it is necessary to quickly find ways to suppress fires and rescue them. Currently, more attention is being paid to new buildings than the existing buildings. In addition, fire information can not be captured in a real time basis for the buildings. In line with the demands of this technology, this study presents a quick and systematic fire management method to minimize damage caused by fire in buildings. As a way to achieve the purpose of the study, ArduinoTM sensors and ExcelTM and RevitTM-DynamoTM tools have been combined to develop a new fire information management system and develop a real-time 3D visualization model. It is expected to contribute to the real-time smart fire management system by proposing a fire management application as a way to utilize it in the future.

  • The number of fire and explosion accidents caused by pyrolysis oil and gas at waste plastic pyrolysis plants is increasing, but accident status and safety conditions have not been clearly identified. Therefore, the aim of the study was to identify the risks of the waste plastic pyrolysis process and suggest appropriate safety management measures. We collected information on 19 cases of fire and explosion accidents that occurred between 2010 and 2021 at 26 waste plastic pyrolysis plants using the Korea Occupational Safety and Health Agency (KOSHA) database and media reports. The mechanical, managerial, personnel-related, and environmental problems within a plant and problems related to government agencies and the design, manufacturing, and installation companies involved with pyrolysis equipment were analyzed using the 4Ms of Machines, Management, Man, and Media, as well as the System-Theoretic Accident Model and Processes (STAMP) methodology for seven accident cases with accident investigation reports. Study findings indicate the need for establishing legal and institutional support measures for waste plastic pyrolysis plants in order to prevent fire and explosion accidents in the pyrolysis process. In addition, ensuring safety from the design and manufacturing stages of facilities is essential, as are measures that ensure systematic operations after the installation of safety devices.

  • We have garnered 3,593 data of gas accidents reported for 12 years from 1995, and then analyzed the LPG vaporizer accidents according to their types and causes based on the classified database. According to the results the gas rupture has been the most common accident followed by the release, explosion and then fire accidents, the most frequent accident-occurring sub-cause is LPG check floater faults. In addition, we have applied the Poisson Probability Functions to predict the most-likely probabilities of fire, explosion, release and rupture with the LPG vaporizer in the upcoming 5 years. In compliance with Poisson Probability Functions results, in the item which occurs below 3 "LPG-Vaporizer-Fire", in the item which occurs below 5 "LPG-Vaporizer-Products Faults-Check Floater" and the item which occurs below 10 appeared with "LPG-Vaporizer-Products Faults". From this research we have assured the successive database updating will highly improve the anticipating probability accuracy and thus it will play a key role as a significant safety- securing guideline against the gas disasters.

  • Currently, safety management is becoming important at domestic construction sites. Despite the importance of safety management, accidents at construction sites are steadily increasing. Fire accidents among safety accidents cause not only negative effects on schedule delay or work plans at construction sites, but also huge casualties. Therefore, the purpose of this research is to extract the causes of fire at the construction site through the case of fire at the construction site, and to prioritize prevention through the analysis of the factors to contribute to the prevention of fire. As a research method, we select fire factors through case, conduct surveys through expert group, and analyze survey through AHP technique. The results of the AHP analysis of the survey of expert groups showed that the workers and their sub-item ranked high. Therefore, the priority for fire prevention was given, and this research is believed to help prevent fire.

  • In this paper, we describe fire risk of Kimchi refrigerator. The Kimchi refrigerator has been widely spread and used starting from the first half of 2000 and recently fire accidents caused by the Kimchi refrigerator emerged as social concern. In particular, in products of a specific manufacturer, it is not an environmental factor, but a characteristic that the fire is caused due to a defect of the product itself is shown. These features are judged to be formed by unique defects regardless of external factor by forming electrically arc mark in the relay element. In this paper, we analyzed the cause of the fire occurring in the Kimchi refrigerator and finally confirmed the characteristic that the fire occurred mainly in the relay element due to insufficient capacity of the relay element. Therefore, when a fire occurs in a product of the same maker as the Kimchi refrigerator mentioned in this paper, it is always judged that the inspection of the relay element should be carried out.

  • Fire fighters are exposed to the risk of many accidents during fire suppression, especially near the high voltage circuit. In order to prevent and analyze the electric shock accidents, measurement of water resistance is crucial. However, this has been one of the overlooked research areas and it has been very difficult to measure the mixed up resistance components separately. In this paper, we measured a total resistance of apparatus and regarded it as a serial resistance of contact resistance and length dependant resistance. Measuring the resistance by varying the length of water stream, the variable resistance and fixed contact resistance appear, which are used to calculate the both components of resistances. In addition, the resistance of fire hose can be calculated from the parallel circuit which is formed by grounding the fire hose with the resistance of water stream. Results show that we can successfully measure the resistance per unit length of water stream and fire hose, thereby proving that this method is a facile way to measure water and fire hose resistance. However, many experiments are still required to obtain the precise contact resistance of ground under various condition and the resistance between the human body and fire hose.
