Evaluasi Sistem Evakuasi Kebakaran pada Kantor Wilayah Direktorat Jenderal Bea Cukai Kalimantan Bagian Selatan

Banjarmasin is one of Indonesia’s ten provinces that are historically prone to fire. To prevent many life losses due to building fire, a building must comply with existing standards and regulations. Therefore, the fire evacuation system was evaluated at the South Kalimantan Regional Office of the Directorate General of Customs. In this research, the method used is descriptive with an evaluative analysis approach where the building data will be compared to related standards and regulations. From this research, it is proven that several fire evacuation system facilities in the building still do not comply with the existing standards and regulations, such as the number of emergency stairs, emergency exits, and the height of handrails on the stairs.

Assessment of Emergency Exit Pathways and Fire Safety Measures in Football Stadium X: An Examination Following Indonesian Guidelines

The most significant football stadium riot tragedy occurred at the National Stadium (Estadio Nacional) in Lima, Peru, resulting in 362 fatalities. The second largest tragedy transpired at the Kanjuruhan Stadium, Malang Regency, Indonesia, leading to 135 deaths. This research aims to evaluate the conformity of evacuation routes and fire protection systems at the one of Football Stadium in Greater Malang, in accordance with the standards and regulations applicable in Indonesia. This analytical descriptive study employs a quantitative research design. The research process involved examining the factual conditions on the ground and subsequently comparing the suitability of evacuation routes and fire protection systems against the standard benchmarks and regulations in place in Indonesia. The results of this study indicate that the conformity level of the evacuation routes, comprising emergency stairs, evacuation routes, safety signs, assembly points, and emergency exits, is at 61.9 percent, denoting adequate compliance. Conversely, the active fire protection systems, encompassing portable fire extinguishers (APAR), hydrants, fire alarms, fire detectors, and sprinklers, show 0 percent compliance, meaning no conformity exists. This study is anticipated to serve as a reference for enhancing evacuation routes and fire protection systems at Football Stadium X: stadium in Greater Malang.

Optimizing safe evacuation using pathfinder: emergency strategies in high-rise and super high-rise complex buildings in the new administrative capital

ABSTRACT Recently, the Egyptian government has sought to create new urban spots. The New Administrative Capital was one of those new urban extensions. Architects and urban designers tended to vertical expansion in planning this city as a result of the high cost of the land. Accordingly, high-rise and super-high-rise buildings have been relied upon in the architectural design of the buildings. This study aims to evaluate the achievement of safe occupants’ evacuation in case of fire for two high-rise and one super high-rise complex buildings based on a set of variables. Staircase design, the use of elevators, and the provision of refuge areas were evaluated, through simulating seven scenarios using Pathfinder software. The simulation results comprised an assessment of average stairs traffic jams, the occupant load density on emergency stairs, and the required safe evacuation time (RSET) for each scenario. It was concluded from the study that staircase design has a significant impact on (RSET) time. As well as, evacuation using elevators or relaying on refuge areas as auxiliary means with the emergency stairs may be safer for these types of buildings. Finally, the study provided technical requirements for using refuge areas and elevators in emergency evacuation in high-rise and super high-rise buildings.

This study aims to describe the implementation of life-saving facilities at RSUD Suraabaya, East Java Province. The research utilizes a descriptive method with data collection through observation and measurement. The research subject is located at RSUD Surabaya, East Java Province, with the K3RS organization as the respondent. The variables examined include the identification of potential fire hazards and life-saving facilities such as emergency stairs, emergency doors, emergency lights, exit routes, exit signs, and assembly points. Data analysis is conducted descriptively. The research findings indicate that the identification of potential fire hazards in both the New and Old Buildings under normal conditions is in accordance with the applicable Standard Operating Procedures (SOP). Emergency stairs and emergency doors fall under the category of being sufficient, emergency lights fall under the category of being insufficient, while the exit routes, exit signs, and assembly points fall under the category of being good. Overall, the assessment of life-saving facilities falls under the category of being sufficient. Therefore, it is recommended that RSUD Surabaya, East Java Province, conducts monitoring regarding the compliance with SOP, carries out improvements, and procures life-saving facilities that do not meet the requirements.

QUALITY OF EMERGENCY STAIR TRAVEL DEVICES

Emergency stair travel devices are designed to evacuate people from buildings and used duringinitial unguided spontaneous evacuations as well as by professional emergency services. Therequirements for evacuation chairs are varied: they are determined by the technical conditions ofthe building, by the specific way of operation of non-professional and professional operators, andon the other hand, they must take into account the specificity of evacuated people. The problemis to indicate the quality parameters of the evacuation chairs so that these chairs can be adaptedto the organization and equipment system. The article aims to indicate and justify such qualityparameters. The starting point was a quantitative analysis of scientific documents. It was foundthat there are only 33 scientific documents directly related to research on the evacuation of peoplewith physical disabilities. Based on the literature, the tested evacuated devices were classified intothree main types: hand-carried, tracked, and sled. Three groups of potential users of emergencystair travel devices have been identified: 1) non-professional rescuer, i.e., a person assisting inthe first spontaneous phase of evacuation; (2) professional rescuer, meaning a firefighter or otherprofessional who is physically fit and well versed in the operation of equipment and evacuationprocedures; this type of user usually appears in the second phase of the evacuation; (3) evacuee. Eachof these groups has specific needs and evaluates the quality of the device in different ways. Basedon the analysis of scientific literature, the following predictors of the quality of emergency stairtravel devices have been identified: average evacuation time(s), evacuation speed (m/s), numberof rescuers (pcs.), effort of rescuers (estimated oxygen consumption or pulse rate) and comfort ofthe person being rescued (estimated by pulse frequency or based on surveys). The expert analysispoints out that essential requirements for evacuation devices vary for different people and do notoverlap. For a person being evacuated, for example, the position of the body during evacuation isimportant, and from the point of view of rescuers, the ease of use, mobility and tolerance for errorsin use are important in case of evacuation. Both groups of rescuers have similar requirements, butthey have different priorities.

Fault tree analysis for subway fire evacuation with agent-based modeling

In the process of the continuous development of subway construction, the safe evacuation of subway passengers has been paid much attention to. As the subway itself has the characteristics of limited space and high passenger density, once a fire emergency occurs, it can cause huge losses only by passive rescue. Therefore, it is important to actively plan for evacuation to reduce life and property losses due to fires in subways. This study aims to develop a fault tree analysis method for identifying scenarios that lead to evacuation failure in subways due to impassability incurred by fires. First, a virtual evacuation model is established using an agent modeling technique, with collected passenger characteristics to calibrate local evacuation behaviors. Then, fire impassability scenarios (e.g. fire(s) in the escalator(s), in emergency stairs, or the combination) are evaluated using the established agent model. Eventually, a fault tree analysis is constructed to identify scenarios that lead to evacuation failures. The research results show that the passability of escalator(s) is critical for subway fire resilience. It is important to use stationary escalator(s) as evacuation pathways for more evacuation capacity. Fire risk management around escalator(s) should be stricter. Passengers and staff are advised to learn how to stop a running escalator to avoid evacuation failures.

Passengers and Crew's Evacuation from Passenger Ships Under Fire: An Agent-Based Model Simulation Study

The characteristics of the passengers have a significant impact on how the evacuation procedures are carried out. During an evacuation, the amount of time it takes depends on how quickly passengers move. There is a correlation between age and travel speed, but not always. As a result of this problem, a significant number of passengers were unable to make it to the assembly point in time for the evacuation, which may have resulted in fatalities. An evacuation simulation will be carried out aboard passenger ships in the event of a fire. This research will employ agent-based modeling to perform the simulation, and it will include modifications for day and night, as well as for the number of emergency stairs used. The findings of this study are the simulation times for the evacuation of passengers and crew for each scenario, with the shortest time for evacuation occurring during the daytime with operational emergency stairs, clocking in at 36.51 minutes, and the longest time for evacuation occurring during the night with damaged emergency stairs, clocking in at 47.43 minutes. Both times are given in minutes. According to the findings, the evacuation circumstances satisfied the standards set by the IMO, which demanded that the entire amount of time spent evacuating be less than or equivalent to sixty minutes

Analysis of Centimeter and Millimeter-Wave Path Loss at Emergency Exit

The path loss model for indoor emergency stairs has yet to get enough attention in the literature. Large-scale (LS) path loss models for a stairwell in a 10-stair academic building are the focus of this investigation. We measured the received power with three different links with sophisticated devices and preprocessed it to find the path loss. LS empirical models can be used to determine the path loss in closed environments as the LS models yield the path loss without considering the details of the environmental configurations. Therefore, this study finds LS models—close-in (CI), alpha-beta (AB), and close-in with a frequency-weighted path loss exponent (CIF), alpha-beta-gamma (ABG), when identifying the best LS models from the measured dataset. The parameters of LS models were justified by validating with the previously reported parameters. The path loss exponents extracted from the measured dataset were slightly lower than those reported in the previous investigations. The AB model showed the minimum standard deviations for the three measurement scenarios of the four LS models studied.

Bezbednost u zdravstvu - evakuacija delimično pokretnih i nepokretnih osoba starijih od 70 godina iz gerontoloških ustanova

Introduction/Aim: Gerontology institutions present objects with the presence of a great number of partly mobile or immobile persons. In emergency conditions, their evacuation because of noted reasons can take longer, so the aim of the research was to present several ways for the evacuation of partly mobile and immobile persons older than 70, from gerontology institutions, and to evaluate necessary evacuation time. Methods: For this research, the software Pathfinder 2020 was used for the calculation of evacuation times and predicting of potential situations during evacuation. The gerontology institution, as a used model, presents an object with a basement and four floors. All floors have 16 rooms with two patients in every room. Floors are connected with main stairs, emergency stairs and with four elevators (two cargo elevators for 12 persons per elevator, and two passenger elevators for 6 persons per elevator). The total number of medical and administrative staff is 44, and the number of users of gerontological institution services is 128. The simulation of evacuation from gerontology institution was realized for four different scenarios: The first, when all the elevators are in function and all stairs are accessible; the second, when none of the elevators works but stairs are accessible; the third, when only emergency stairs are in function; the fourth, when only main stairs are in function. Each of these four scenarios has four different situations that depend on the evaluated speed of patient`s movement. Results: The evacuation time when it is possible to use all elevators and stairs is from 895 seconds (14.9 minutes) (for the fastest movement of persons - the first situation) to 958 seconds (16 minutes) (for the slowest movement of persons - the fourth situation), for main and emergency stairs from 984 to 1111.1 seconds (16.4-18.5 minutes), only for emergency stairs from 1997.6 to 2765.3 seconds (33.3-46.1 minutes), and only for main stairs from 1365 to 2342 seconds (22.8-39.0 minutes). Conclusion: The usage of computer software Pathfinder 2020 for the simulation of evacuation presents a very important, safe and cheap way for predicting evacuation way and speed, which can contribute to the national strategy for emergency situations.

Correspondence Between Reliability of Rental Flat Building and Space Needs

Flats for rent need to be designed so that residents move comfortably and can save themselves in times of disaster. This research was conducted with the aim of knowing the spaces needed by the occupants by taking into account the reliability of the building-safety and comfort. Some aspects of building reliability are motion comfort and safety. Data was collected by an online questionnaire, which was distributed to residents using non-random sampling. The collected text data was analyzed by content analysis. From the results of the analysis revealed that residents tend to be comfortable moving in rental residential units. Residents need a secondary space that is a shelf and work space. Storage space represents the meaning of storage of small items. Work, study and storage of equipment represent the meaning of workspace needs. Residents need some secondary space in a residential unit that has aspects of motion comfort and security during disaster evacuation. Motion comfort mainly represents a little furniture, has storage space, and doesn't interfere with activities like sitting and watching television. The number of residents felt safe moving when disaster evacuation in vertical housing was almost the same as the number of residents who felt the evacuation route was not ideal. Easy access is achieved, wide circulation room, near the emergency stairs is represented by the meaning of feeling safe moving during a disaster evacuation. There is no special emergency ladder, narrow circulation space, the condition of a damaged staircase at the time of disaster evacuation is represented by meaning not ideal. This study found a significant relationship between the reasons for motion comfort and the presence of space requirements. There is no significant relationship between disaster evacuation security and secondary space requirements.

Evacuation Simulation based on Emergency Stair

Evacuation Simulation based on Emergency Stair

Performance evaluation of refuge floors in combination with egress components in high-rise buildings

In recent decades, the number of high-rise buildings has increased. It is therefore essential that emergency evacuation should be taken into account for conditions such as fire, explosion, and terrorist attacks. This research aims to evaluate the performance of the emergency egress components in the architectural design of high-rise buildings. This assessment includes the number and location of stairs and elevators, and most importantly, the number and dimensions of the refuge areas. The main question of this study is: What is the relationship between the number of elevators and emergency stairs with the number and location of refuge areas in a high-rise building for finding the optimal time of emergency egress? In this research, the simulation and modeling methods are used as well as the library data collection method. The research considers 12 different scenarios to investigate the optimal time of emergency egress in a 40-storey high-rise office building. The simulations are done using an algorithm written by the Pathfinder software. The independent variables are the number of elevators, stairs, and refuge floors, and the dependent variable is the most number of people left in the standard time of an hour in the simulation. Results of the research show that in a 40-storey building, having a refuge floor in the middle, will allow more people to be evacuated. That could be feasible by making less nodes in the refuge floor plan that prevent the formation of long queues for the use of elevators.

The Effectiveness of Vertical Transportation (Emergency Stairs and Ramp) as a Means of Egress for Safety of the Intensive Care Unit Patients in the Emergency Condition

Construction of multi-storey building is an alternative answer to the limitations of the existing land. It is including the health facilities building of RSUD Dr. Saiful Anwar Malang. This has given a matter of emergency response due to the emergencies condition. Hospital evacuation is relatively difficult and slow, since the building is dominated by patients with health problems, and loss of consciousness that need help from the health officer, due to evacuation in an emergency condition.

Active and passive fire protection system in academic building KH. Mas Mansur, Islamic University of Indonesia

According to the theory of fire triangle, the existence of combustible materials, heat, and oxygen can cause fire disaster. KH. Mas Mansur building, Islamic University of Indonesia has a fire protection, but rarely to be checked regularly and the number of equipment is less standard as well as the lack of an evacuation route map to facilitate the evacuation process. Inside the building also does not provide safety signs such as the evacuation directions, exit, and warning in case of fire. Therefore, researchers analysed the infrastructure of prevention and control in the building KH. Mas Mansur. Researchers used the method of observation, interviews, and checklist to know the condition directly, and compare with the standard regulations. Results concordance rate of existing infrastructure is 67% fire extinguisher, hydrant box 56%, 71% alarms, sprinkler 0%, 40% detectors, emergency doors 71%, 50% emergency stairs, assembly point 0% and directions 0%. The current results were below the standard of at least 80%. As for recommendations, researchers create a new evacuation map then put the existing infrastructure according to standard regulations, and it had consulted with the specialist of Occupational Safety and Health in the field of fire.

Perspectives of occupants with mobility impairments on evacuation methods for use during fire emergencies

Since the tragic loss of life in the World Trade Center disaster, efforts have refocused on the provision of safe and efficient evacuation procedures, especially for occupants who cannot negotiate exit stairs without assistance. Several evacuation options have been designed specifically for people with mobility impairments, including occupant evacuation elevators (OEEs). Face-to-face interviews were conducted with 51 participants with mobility impairments working in buildings located in five major metropolitan areas within the U.S. The dual goals in this study were to gain an understanding of how building occupants with mobility impairments evacuate multi-story buildings during fire emergencies and to identify perspectives on the use of elevators during fire evacuations. Data analysis of interviews highlighted the benefits and concerns of study participants involving both typical building evacuation methods (i.e., emergency stair travel devices and areas of refuge), as well as evacuation methods using elevators. This study also highlights improvements that can be made to elevator systems, particularly OEEs, to reduce anxiety about fire evacuation and increase trust in the occupant evacuation elevator system via a variety of means, including education and consultation in preparation for the evacuation, information and attention to occupant needs while the evacuation is taking place, and two-way feedback and discussions afterwards. Key to all of these improvements is the need to include those with mobility impairments in the planning and execution of fire evacuations and to facilitate their ability for self-evacuation as much as is practicable. The results of this study led to guidance on evacuation planning and procedures, the use of existing elevators for evacuation of people with mobility impairments, and the use of occupant evacuation elevators.

이중외피 구조 건축물의 피난성능 개선에 관한 연구

본 논문은 피난 안전성 평가를 통해 이중외피 구조가 적용된 건축물에서의 피난 성능 개선방안을 제시하고자 한다. 이중외피 구조가 적용된 건축물은 화재 발생시 굴뚝효과로 인한 상층 연소확대 현상이 빠르고 그 특성이 각 구조별로 다른 특성을 갖고 있으며 설계 및 제도적 기준 또한 미비하여 일반 건축물에 비해 피난 안전성을 확보하기 어렵다. 따라서 본 논문에서는 10층의 단일 피난계단이 적용된 이중외피 건축물로 가상의 모델링을 구성하였으며, 피난 성능을 개선하기 위한 방안으로 피난 완료시점을 옥외로의 탈출까지로 변경하고, 각 구조별 위험도를 고려한 경보방식을 제안하였다. 그 결과 기존의 경보방식과 비교하여 박스형은 약 26.4%, 복도형은 약 29.1%, 샤프트-박스형은 약 23.4%, 전면형은 약 26.3%의 피난 성능이 개선되었고, 전층의 재실자의 안전을 확보 할 수 있었다. This study examined an effective way of measuring the evacuation performance in buildings, which are applied to a double skin facade through an evaluation of the escape safety. Buildings with a double skin facade appeared to have a faster combustion expansion speed for the upper floor if a fire occurs. Moreover, a double skin facade is more difficult to escape safely than a general building construction because of the limited design standards. Accordingly, this study suggested virtual modeling including single emergency stairs and alarm systems considering the risk in each structure of buildings. These results showed that box-type double skin, corridor access type, shaft-box type, and multistory facade systems showed a 26.4%, 29.1%, 23.4%, and 26.3% increase in evacuation performance, respectively, as well as securing the safety of occupants.

Diversity and Utilization of Public Space in Rusunawa Mariso, Makassar – Indonesia

Rusunawa was built to anticipate the needs of low-income residents for affordable urban homes. This study identifies its diversity and designed function and evaluates the existing utilization of public spaces in Rusunawa. Furthermore, it identifies the underlying reasons for them. Structured observation is applied through person-centered mapping, with a combination of structured and unstructured interviews. Public spaces in Rusunawa can be categorized into eight locations (corridor, main stair, emergency stair, common room, building entrance, parking area, open space, and mosque), where activities of five types are identified to take place (private, social, trading, supporting, and worshiping activities). Similar backgrounds in landed houses have created a strong emotional bond among occupants and obscured the boundaries of spaces.

Long-Lasting and Highly Efficient TRIAC Dimming LED Driver with a Variable Switched Capacitor

A triode for alternating current (TRIAC) dimming light emitting diode (LED) driver, which adopts a variable switched capacitor for LED dimming and LED power regulation, is proposed in this paper. The proposed LED driver is power efficient, reliable, and long lasting because of the TRIAC switch that serves as its main switch. Similar to previous TRIAC dimmers for lamps, turn-on timing of a TRIAC switch can be controlled by a volume resistor, which modulates the equivalent capacitance of the proposed variable switched capacitor. Thus, LED power regulation against source voltage variation and LED dimming control can be achieved by the proposed LED driver while meeting the global standards for power factor (PF) and total harmonic distortion (THD). The long life and high power efficiency of the proposed LED driver make it appropriate for industrial lighting applications, such as those for streets, factories, parking garages, and emergency stairs. The detailed analysis of the proposed LED driver and its design procedure are presented in this paper. A prototype of 80 W was fabricated and verified by experiments, which showed that the efficiency, PF, and THD at V s = 220 V are 93.8%, 0.95, and 22.5%, respectively; 65 W of LED dimming control was achieved with the volume resistor, and the LED power variation was well mitigated below 3.75% for 190 V s < 250 V.

Utilization Driven Diversity of Public Space in Rusunawa Makassar, Indonesia

Affordable urban homes for low-income residents were built in forms of Rusunawa, where functions of public spaces in such place have been distorted from their initial functions. Study identifies the underlying reasons of the changes through observations, structured and unstructured interviews, combination of both interview, and person-centered mapping. Public spaces in Rusunawa can be categorized into eight locations (corridor, main stair, emergency stair, common room, building entrance, parking area, open space, and mosque). Variety of residents’ activities (private, social, trading, supporting, and worshiping) in the spaces was identified for analysis and data enrichments. Residents’ social background understanding should give a better planning on public spaces integration in city residential areas.
