The purpose of this study is to use an evacuation simulation program to measure the change in evacuation time according to the width of the evacuation route due to the installation of an intermediate sales counter and the placement of a shopping cart between the sales counters of a large supermarket and to analyze the results. Currently, the “Distribution Industry Development Act” does not regulate the size and installation method of intermediate sales counters installed between sales counters that serve as practical evacuation routes in the event of a fire at a large supermarket, the size of shopping carts, etc. Considering this, we set evacuation route widths of 40, 50, 60, 70, 80, and 100 cm and compared and analyzed evacuation times according to various variables in the facility space. As a result of the experiment, as the width of the evacuation route was expanded, there was a significant difference in the evacuation time, from a maximum of 468.3 seconds to a minimum of 320.8 seconds. Considering the safety of evacuees in large supermarkets used by many people, it is time to regulate the size of intermediate sales stands installed between sales counters in large supermarkets and shopping carts that can become obstacles in an emergency.
승선 인원이 많은 실습선은 화재가 발생하는 경우 대형 인명피해로 확장될 수 있으며 이에 따라 선원법 및 Safety Life At Sea(SOLAS)에서는 퇴선 훈련에 대한 중요성을 강조해 왔다. 따라서 본 연구에서는 승선 인원이 많은 국립목포해양대학교의 세계로호를 대상선박으로 선정하여 preliminary hazard analysis(PHA) 정성적 위험성 평가 기법을 통해 각 deck의 화재 사고 위험빈도와 심각성에 대하여 예측하였다. 또한 위험성이 높은 구역에서의 화재를 가정 한 뒤, 그 위험성을 정량적으로 예측하기 위하여 대피 시간 및 인구 밀도에 대 한 시뮬레이션을 수행하였다. 그 결과, 총 대피시간이 인구 분포가 한 구역에 집중되어 있던 식사 시간을 가정한 시나리오에서 501초로 가장 길게 예측되었으며 시나리오에 따라 일부 deck에서 1.4pers/㎡ 이상의 상대적으로 높은 인구밀도를 나타내며 대피 인원이 정체되는 현상을 보였다. 본 연구 결과는 다양한 피난 시나리오에 따른 대피시간 및 인구밀도를 정량화하여 실습선의 상황에 맞는 훈련 시나리오 를 개발하기 위한 기초자료로서 사용될 것으로 보이며 추후 수학적 모델과 실험값의 비교를 통하여 연구를 확장할 수 있을 것으로 예상 된다.
The objectives of this study is to classify evacuation types, derive the characteristics of 4 types, develop and discover evacuation routes within the performance hall space, and present the statistical classification results of the evacuation classification model by classification type. To achieve this purpose, the characteristics of each evacuation type's four types are applied through a network reliability analysis method and utilized for institutional improvement and policy. This study applies for the building law, evacuation and relief safety standards when establishing a performance hall safety management plan, and reflects it in safety-related laws, safety standards, and policy systems. Statistical data by evacuation type were analyzed, and measurement characteristics were compared and analyzed by evacuation types. Evaluate the morphological similarity and reliability of evacuation types according to door width and passage length and propose the install position of evacuation guidance sign boards. The results of this study are expected to be used as basic data to provide operation strategies for safety facility evacuation information sign boards according to evacuation route classification types when taking a safety management plan. The operation strategy for the evacuation sign boards installation that integrates employee guidance and safety training is applied to the performance hall safety management plan. It will contribute to establishing an operational strategy for performance space safety when constructing performance facilities in the future.
The purpose of this study is to propose measures to increase evacuation safety by calculating the habitable time using a fire and evacuation simulation program for the Room-escape cafe currently in operation, and comparing and analyzing it with the evacuation required time. Assuming a fire due to overheating of electric heaters in use in front of the warehouse, the habitable time was calculated through fire simulation, and the occupant's evacuation time calculated through evacuation simulation according installation of safety facilities, etc. was compared and analyzed with the habitable time. In the case of escape room cafes with safety facilities installed, evacuation safety was satisfied, but in escape room cafes without safety facilities, the evacuation safety was not secure. As a result of analyzing evacuation safety for each scenario based on the ASET analyzed in the fire simulation, it was found that in scenario 1, evacuation safety was secured and everyone successfully evacuated, while in scenario 2, no one succeeded in evacuation. These results can be said to confirm that the installation of safety facilities is very important in business establishments such as escape room cafes, which become enclosed structures when games are started.
Human and material damage can be reduced if the risk is evaluated by engineering analysis of fire combustion products, smoke concentration, and smoke movement speed in the event of a fire in apartment houses and officetels. In this study, a lot of research on related safety evaluation in the basement needs to be studied and reflected in design, so experimental research was conducted to analyze the flow of smoke through computer simulation and provide analysis data through evacuation safety evaluation. First of all, the five-story underground parking lot subject to simulation has a large floor area, which is advantageous for improving evacuation safety performance, but it uses temperature detectors to increase detection time and fire spread speed. Second, it was analyzed that the evacuation time at all evacuation ports did not exceed the evacuation time, and as the time from the start of evacuation to the evacuation time was 216.9% compared to the travel time, it was evaluated that the safety performance of the evacuation was secured. Third, the above simulation results are a comprehensive safety evaluation based on the non-operation of fire extinguishing facilities in the fire room to increase safety, which means that smoother evacuation safety performance can be secured by linking fire extinguishing facilities.
Social welfare facilities are used by a wide range of local residents, including vulnerable populations such as the elderly, children, and people with disabilities. During emergencies like fires, confusion can arise as these individuals try to evacuate. Evacuation simulation results have shown that utilizing evacuation systems based on specific evacuation scenarios can significantly decrease the time required for evacuation compared to general evacuation procedures. By anticipating potential fires based on changes in social and facility environments, appropriate evacuation scenarios can be developed and applied to evacuation systems, thus contributing to the safety and security of individuals during emergencies. In conclusion, for social welfare facilities that serve a large number of people, it is necessary to expand the focus on performance-based design depending on the size of the facility, and to continuously develop and train for appropriate evacuation scenarios that align with changing facility environments.
The object of this study is to evaluate whether the means of egress of Jechon Sports Center and Miryang Sejong Hospital, where massive fire human casualties occurred in 2017 and 2018 respectively, comply with NFPA 101(Life Safety Code), and to suggest the need for supplementation of domestic means of egress regulations. The study evaluated the number and arrangement of the means of egress, travel distance, common path of travel, dead end and discharge from exit for each building by applying the means of egress regulations of NFPA 101. As a result of the evaluation through NFPA 101, the travel distance was appropriate, but some of the other items except for the travel distance did not meet NFPA 101. The regulations that need to be supplemented are 1)occupant load calculation 2)egress capacity calculation 3)continuous concept of means of egress 4)concept of common path of travel. It is especially necessary to revise the requirement for fire door of the evacuation floor(normal 1st floor) of the stairwell in case of below the five story building.
This study chiefly aims to clarify efficient methods considering behavioral pattern of refugees in multi-use facilities which can be applied to architectural planning. Accordance with COVID-19 situation, it is mandatory to check the temperature of visitors as a measure for the prevention of COVID-19 in multiuser facilities. When disaster occurs, for people in multi-use facilities such as medical facilities, museum, concert hall etc, it is difficult to find out short and right route to outside since the spatial characteristics are not familiar to visitors. If we design floor plans and circulation system considering behavioral pattern of refugees we can prevent the spread of disasters when they happen.
이 논문은 토마스 핀천의 바인랜드에서의 인물들의 ‘배제된 자’(The Preterite)로서의 역할과 의미를 탐색하고, 미국 사회 속 반-문화 혹은 대항문화의 역사적 의미와 사회적 의의를 문학적으로 접근한다. 핀천의 인물들의 시대성과 자유로운 영혼들의 피난처로서의 바인랜드에 대한 분석을 통해 핀천의 주체에 대한 시각을 권력과 ‘배제된’ 자의 사회 구조를 통해 접근하고, 핀천의 ‘배제된 자’들의 연대감과 그들의 ‘배제된’ 영성의 양상을 연구한다. 미국의 1920년대와 30년대의 노동 운동과 40년대 50년대의 저항 운동, 60년대의 히피 세대의 반문화 운동을 겪은 ‘배제된 자’의 저항의 역사와 문화적 장소로서의 바인랜드에 대한 분석을 통해 그들의 과거, 현재, 그리고 미래에 대한 연관성을 연구한다. 이 과정에서 ‘배제된 자’들의 ‘피난처’인 바인랜드는 그들 사이의 연대감과 다른 종교뿐 아니라 소위 다른 세계인 타나토이드라는 존재까지도 아우르는 ‘배제된’ 영성을 통해 서로 권력으로부터 보호하고 자연 속에서 평안을 얻는 구원의 장소임을 보여준다. 결론적으로 핀천은 이 소설을 통해 ‘배제된 자’들은 기독교적 전통을 통해서만이 아니라 ‘배제된’ 영성에 의한 ‘구원적 대안’도 가능한 것임을 보여준다.
Marine accidents caused by ships are very diverse, such as collision, sinking, stranding, grounding and fire. In particular, persons on passenger ship are unspecified and not trained, so it makes evacuation harder. For this reason, an evacuation plan that considers diverse situation in ship is needed. Effective evacuation planning requires training in consideration of various evacuation situations. In this paper, we investigated the time elapsed on evacuation in various situations from “HANMIR,” the fishery training ship of the Korean Institute of Maritime and Fisheries Technology, using a Ship Evacuation Analysis Program (SEA-Pro) which is introduced to the society. We assumed a situation that has not only inconveniences for real training but also the possibilities of happening. Not all trainees are resting in their cabin, so we assumed positions such as they are in the bridge or engine room and applied fire and flooding situations. We assumed that the time for alerting the situation would be short, so we applied only elapsed time of movement. Those analyses could be helpful in three ways. The first is predicting the consequence of possible accidents. There are some conditions that can be appliable to this model, such as the decreased area of sight in those situations. The second is concluding the optimal limit of carriage and placement of safety instruments on building a new ship. The third is to be a base data for ships to make a new effective evacuation plan based on these analyses.
PURPOSES : This study aims to deduce the appropriate interval of cross passage for small vehicle exclusive roads within urban underground roads to ensure safety.
METHODS : This study evaluated evacuation safety by fire and evacuation simulations. The simulation was applied to a passenger-caronly urban underground road, which was performed in the entry/exit section with a gradient of 6.0% and the mainline on level grade. The values of the variables for the simulations were determined to be close to the actual situation based on of the statistics and the results of previous studies. In the simulation scenario, the cross passage interval was visible. The evacuation safety was evaluated by comparing the “evacuation completion time” and the “smoke diffusion time.” Evacuation safety can be desirable when the evacuation completion time is shorter than the smoke diffusion time.
RESULTS : According to the results of the simulation, the desirable cross passage interval is 180 m for the entry/exit sections with a 6% gradient in passenger-car-only tunnels. This criterion may be prolonged to an interval of 210 m and a width of 0.9 m for the construction reduction, based on the results of the statistical analysis.
CONCLUSIONS : According to the results of this study, the risk indices of the “Small Vehicles Road Tunnel Fire Safety Facility Installation and Management Guidelines” may be supplemented by the tunnel class and the gradient of the entry/exit section. In addition, the guideline may provide an improved interval of evacuation cross passage and the width of the cross passage door by the safety index.
The public relations room of the waste disposal facility is a space that can be visited by a large number of unevaluated personnel. Therefore, it is essential to design against fire, and research on fire and evacuation is essential. In this study, in order to evaluate the safety of the occupants in the event of fire and evacuation based on the life safety standards of occupants, the increase in risk due to heat, visible distance, and toxic gases on a plane 1.8m from the floor, which is the limit of breathing of the evacuee, over time. It was analyzed by location. As a result, the RSET of the P-01 exit was 93.0 seconds and the ASET was 272.6 seconds, the RSET of the P-02 exit was 45.8 seconds, the ASET was 147.7 seconds, the RSET of the P-03 exit was 106 seconds, and the ASET was 182.9 seconds.
This study analyzed the appropriate placement method by floor for evacuating all occupants during the nighttime through evacuation simulation. The analysis results are as follows. First, when non-self evacuating patients were placed on the first floor, 266 patients and 6 workers were found to be evacuated after 460 seconds. This result shows that it is meaningful to place non-self evacuating patients on the lower floor with a time that is faster than 540 seconds, which is an evaluation criterion set using life Safety standards for human. This result is a time faster than the evaluation criteria of 540 seconds, which is set using the life safety standards, and it can be confirmed that it is meaningful to place non-self evacuating patients on the lower floor. Next, as a result of placing non-self evacuating patients from the first floor to the fourth floor, it was found that evacuation of all occupants required 460 seconds for the first floor, 834 seconds for the second floor, 1,508 seconds for the third floor, and 1,915 seconds for the fourth floor. These results indicate that the placement of non-self evacuating patients on the rest of the floors, except for the first floor, can lead to dangerous results in excess of 540 seconds, which is a flashover time. As a result, it is necessary to place non-self evacuating patients on a lower floor for safe evacuation. The study has limitations except for comparative analysis of changes in evacuation time due to changes in the number of workers at eldery care hospitals and situations in which fire-fighting facilities such as sprinkler facilities operated. It is necessary to study the evacuation time linked to the operation of the fire-fighting facilities and the evacuation time according to the change in the number of workers in the future.
This study analyzed the evacuation time in indoor stadiums when exits that automatically open/close when the fire sensor is triggered are installed as a means to improve the problem of closing certain exits. Firstly, when spectators on the 2nd floor stands exit through the 1st floor exits, the RSET of all inhabitants was 529.8 seconds when the automatic opening/closing exits are broken and employees are not present. Secondly, when spectators on the 2nd floor stands exit through the 1st floor exits, the RSET of all inhabitants was 445 seconds when the automatic opening/closing exits with 750mm width are working but employees are not present. Lastly, when spectators on the 2nd floor stands exit through the 1st floor exits, the RSET of all spectators was 337 seconds when the automatic opening/closing exits with 1,500mm width are working and employees are present. As a result, it was revealed that the evacuation time is shortened when the automatic opening/closing exits are working. Additional comparative studies with actual simulations of people evacuating an indoor stadium and firefighting simulations considering smoke flow are necessary.
In this study, fire and evacuation safety of environmental energy facilities using fire and evacuation simulation was examined as part of performance-oriented design. The worst-case fire scenarios in which fire-fighting facilities such as sprinkler fire extinguishing and smoke control systems are not working, and the FDS analyzes the visibility, temperature distribution, and carbon monoxide concentration distribution through FDS. The safety was examined. As a result, it was proved that evacuation could limit the visibility, temperature, and carbon monoxide concentration in a smooth range, based on the safety standards set by relevant laws. In other words, it was possible to verify the safety of fire and evacuation for environmental energy facilities where a large amount of combustibles and fires coexist.
위법성조각사유의 전제사실에 관한 착오(이하 ‘위전착’이라고도 한다)를 일으킨 행위자는 법에 충실하게 행위하려고 한 것이므로 과실범에서의 위전착은 사실의 착오로 평가된다. 그런데 과실범에서는 이미 고의가 존재하지 않으므로 고의조각/과실범이라는 사실의 착오는 의미가 없다. 따라서 과실범에서는 이를 금지착오로 다루는 것이 행위자에게 유리하다는 입장이 있을 수 있다. 그러나 사실의 착오와 금지의 착오가 본질 적으로 가치차이가 있다는 점에서 이러한 해결책은 받아들이기 어렵다. 이처럼 착오론에 의한 해결이 곤란하다면 과실범론에 의한 해결을 모색하게 된다. 이때 위전착은 사실의 착오이므로 과실범이론에 따른 해결방법에서도 금지착오의 적용효과 보다는 유리하게 내지 적어도 불리하지 않도록 해야 한다. 이에 과실범에서의 위전착은 주관적과실 내지 책임과실에 영향을 미친다는 입장이 제시되고 있다. 하나는 심리적 압박 상황에서는 개인적 주의능력이 제한되어 과실범의 위전착은 주관적 과실 내지 책임과실이 조각될 수 있다는 견해이다. 다른 견해에 의하면 행위자의 개인적 능력에 무슨 흠결이 있는 것이 아니며, 따라서 행위자의 개인적 능력을 기준으로 하여 볼 때 주관 적 인식가능성은 긍정되게 된다. 심리적 압박을 받고 있다고 볼 수 있지만 행위자는 정당방위나 긴급피난의 행사를 냉정하게 계산하고 있다는 것이다. 이에 따르면 오상 방위나 오상피난은 기본적으로 이익의 충돌상황이고, 이러한 의미에서 위전착은 위법 하지만 면책이 가능한 허용된 위험으로서 주관적 과실 내지 책임과실이 제한될 수 있게 된다.
어떠한 해결방식이 이론적으로 가능하고 더 나은 것인지 필자로서는 잘 모르겠다. 그러나 본고에서 어느 정도 암시는 되었으리라고 보여진다. 어쨌든 과실범에 있어서 의 위법성조각사유의 전제사실에 관한 착오가 착오론과 과실범론을 종래와는 다른 시 각으로 바라볼 수 있는 계기를 우리에게 제공해 줄 수도 있지 않을까 생각된다.
In this paper, we analyzed the safety on static and dynamic characteristics of a top-down evacuation instrument fixed on the exterior walls of a building using finite element analysis. For this purpose, the stress distribution characteristics of the H-beam structure were analyzed and the equivalent stress distribution, deflection displacement and natural frequency characteristics of the overall structure of the evacuation instrument were analyzed. The structures were applied with the materials of SS440 and SUS304. The static analysis results showed the elastic behavior with safety coefficients from 2.4 to 2.9, by confirming the structural safety. In addition, the analysis of the natural frequency characteristics confirmed that the vibration characteristics were higher than the external conditions of 20Hz.
