To design the education and training content, the Korea Fire Safety Institute, which educates and trains fire safety managers, arranges the training content in the textbooks provided to actual fire safety managers and sets the sequence of operating principles and inspection methods. The purpose is to provide fire safety managers with realistic inspection methods and practice opportunities by implementing them in augmented reality. The education and training program allows learning about automatic fire alarm systems in the following order: structure and operating principles → inspection and practice → assessment. In structure and operating principles, fire safety managers can acquaint themselves with the role of automatic fire alarm systems and facility components and circuit tests according to operation principles. During inspection and practice, at least three inspection methods are learned for each facility. Finally, the assessment refers to the actual evaluation and achievement standards of the Korea Fire Safety Institute, checking a facility in a given mission without guidance or explanation based on the aspects learned in inspection and practice. In addition, it reviews the aspects learned in theory by including a quiz during inspection to improve proficiency by setting it up to be applied in practice.","PeriodicalId":514545,"journal":{"name":"Fire Science and Engineering","volume":"110 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140422488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the smoldering cotton fire experiment comparing ODM and ASD based on the concentration standard of 15 %/m, which are the operating concentrations of the fire detection of type-2 smoke detectors, indicated a delay of approximately 2∼4 min in the ASD fire detection time. In addition, in the case of the smoldering fire, the CO concentrations appeared to be 37 ppm and 62 ppm at the ASD1,2 fire detector operating concentrations, resulting in high concentrations of combustion gas. Furthermore, in the case of a smoldering fire rather than a flame fire, despite a large amount of smoke/aerosol and gas owing to incomplete combustion because of the lack of buoyancy, it did not flow into the smoke detector chamber and was not distributed on the ceiling; this required a long time to detect the fire. Accordingly, smoke detector operation tests for various smoke/aerosols must be conducted in Korea to meet the international standards of firefighting technology.","PeriodicalId":514545,"journal":{"name":"Fire Science and Engineering","volume":"131 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140423853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By reflecting on the characteristics of evacuation facilities and the occupants of multi-occupancy buildings, a scenario similar to that of a real situation was designed through unexpected situations that could occur during actual evacuation induction. Each evacuation facility in the scenario was developed by applying additional methods considering the factors influencing the evacuation in the previous case, referring to Article 4 (1) of the adaptability of evacuation equipment according to the installation location of firefighting objects. The developed scenario was a multi-occupancy building with four basement levels and 50 floors above the ground with a piloti structure and was designed based on the order of evacuation initiation → induction of evacuation → gather at the evacuation site → rescue recipient state report. The details were designed to be applied to practical training by assigning elements that can occur in real situations by causing evacuation using evacuation facilities according to the number of fire floors, assigning situations through various characteristics of occupants, and inserting role conflict elements through unexpected situations. By conducting practical and feasible education for fire safety managers, they can flexibly cope with unexpected situations that may occur in the process of inducing occupants to evacuate in the event of a fire while on duty and improve their skills in using evacuation facilities.","PeriodicalId":514545,"journal":{"name":"Fire Science and Engineering","volume":"8 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140418891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two types of solid propellants of different sizes and three TNT equivalents of composite propellants were applied to empirical correlation to derive incident pressure and impulse. These were used in probit analysis, and the effects on the person and structure were quantitatively analyzed to determine the risk of solid propellant explosion. The larger the propellant and the more the TNT equivalent, the higher the incident pressure and impulse. Moreover, the amount of propellant had a more significant effect on the impulse than the incident pressure. The effects of the incident pressure and impulse on human were observed to be greater in the order of probability of ruptured eardrums, death from head impact, death from whole-body displacement impact, and death from lung damage. Furthermore, the effects on the structure were observed to be greater in the order of probability of breakage of window, minor damage, major damage, and collapse of the building.","PeriodicalId":514545,"journal":{"name":"Fire Science and Engineering","volume":"39 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140421790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
