Since the hydrofluoric acid spill accident in Gumi in 2012, the current situation has continued to suffer from makeshift responses or feeble national system maintenance in preparing real countermeasures against chemical accidents, regardless of their repeated occurrence and seriousness. Industrial chemical accidents have an enormous ripple effect on the whole country and society. The purpose of this study is to propose ways of establishing directions for the national disaster management system against repeated occurrence of chemical accidents. To achieve this goal, the present study proposed improvement measures of response system for industrial chemical accident through the analysis of the current response system and structural causes of disaster control failure for chemical accidents.
In the event of specific unpredictable and unprecedented disasters that have happened more frequently, it is desirable that efficient fire-preventing actions are quickly initiated from the epic at an early stage. At this point, the Volunteer Fire Department becomes especially indispensable for assisting the Fire service. The Volunteer Fire Department has not kept up with the improvement of the society and has not improved the environment of the fire service area, even if it should adapt to changes in its role.
Smoke detectors play a vital role in evacuation and safety during fire incidents, as they directly contribute to the reliability and accuracy of firefighting systems. However, if not installed properly, smoke detectors can trigger unwanted fire alarms (UWFAs), particularly in studio-type apartments. Therefore, this study aimed to develop a method for reducing UWFAs by addressing the challenges posed by cooking by-products in such environments. The proposed algorithm was validated through tests, considering relevant literature and standards, and utilizing indoor air quality sensors. Verification tests were conducted to enhance the accuracy of the algorithm. Based on the experimental results, cutoff values of 5 ppm for CO and 7000 μg/m3 for PM10.0 were proposed as criteria for identifying UWFAs caused by cooking by-products.
Statistics from the Fire Department illustrate that over the last five years, the rates for fire enforcement arriving within the Golden Time is on average only 60 %, and this is not a high enough safety rate. Golden Time has to be secured because it is directly related to saving lives, but at present, it is not working well. Fire engines would be capable of traveling within the Golden Time based on the following three factors: securing the fire engines, securing the emergency route, and the limitations of the 119 system. This research is based on the standards of advanced overseas countries such as the U.S., Japan, and Europe, and it examines the limitations of domestic standards and systems in securing Golden Time. Additionally, this research suggests the problems that exist and develops specific solutions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
