According to fire statistics analysis of the nation's fire department between 2015–2019, the most common cause of fire was electrical fire. As reported, 47,135 fires were caused by electricity, 22,852 were caused by mechanical causes, and 871 were caused by gas leakages. In this study, the fire adaptability of microcapsulated fire extinguishing agents was tested against small space electrical fires, such as electrical distribution boards. The tests showed that the fire extinguishing agent inside the capsule was released after initial fire contact and the fire of n-heptane was extinguished within 4.48 seconds (on average). Therefore, the KFI small space B-level fire extinguishing test by the Korea Institute of Fire and Industry met the criteria that the fire was extinguished and did not reoccur within 90 s after the end of the preliminary combustion. In addition, this fire extinguisher (agent) dramatically improved the volume of existing cylinder-type fire extinguishers for small spaces. However, there are no national fire safety codes (NFSCs) for this agent. Therefore, it is necessary to enact fire safety standards for this agent for smooth-field applications.

According to the current firefighting facility ordinance, connecting water pipes can be more than five stories in length, and the installation standard is applied to specific objects with a total floor area of > 6,000 m<sup>2</sup> or more than seven stories. This standard is intended to enable fire brigades to quickly move to a fire point and extinguish a fire with extinguishing water supplied smoothly. However, the strict fire safety standards make it possible to install both the connecting water pipe facility and the indoor fire hydrant and sprinkler connecting the water outlet, thus creating a fire extinguishing facility that firefighters cannot use at the fire site. In this study, both domestic and foreign standards and fire cases of consolidated water pipes were reviewed, and various problems were analyzed through field surveys, experiments, and surveys. In addition, using the engineering mathematical calculation method and mathematical calculation program, it was confirmed that direct delivery to the 50th floor is possible with the A1 pump on fire trucks. The fire safety standards have been revised to ensure that fire brigades can extinguish fires under any circumstances, and it is suggested that piping should be installed.

Fire departments are expected to respond quickly and effectively to disasters by extinguishing fires and rescuing those in harm’s way, for example. They are also required to prevent fires and disasters by enforcing fire-prevention measures at hotels and care facilities and to monitor safety measures in facilities storing hazardous materials. Concerns have arisen that destructive disasters may occur due to environmental changes in local communities or due to the Tokyo Metropolitan earthquake or Nankai Trough earthquake. To ensure that fire departments use their firefighters, materials and equipment effectively to prevent or control fires and reduce damage of disasters, research and development (R&D) on fire safety and disaster preparedness must be conducted actively and resulting findings must be applied in advanced fire safety and disaster preparedness activities. Fire safety R&D in Japan is undertaken by the National Research Institute of Fire and Disaster,which is the research organ of the Fire and Disaster Management Agency. Here R&D is being conducted on safety measures for facilities storing hazardous materials, fire-fighting robot technology, and fire extinguishing techniques. Fire departments in major cities also study firefighting operations and advanced materials and equipment. Although the number of institutions directly conducting fire safety R&D is limited and allotted research and development budget is extremely small. Private-sector R&D in fire safety unfortunately cannot be described as vigorous because it focuses on equipment used by fire department personnel and fire-safety facilities required by law, such as fire engines and rescue materials and equipment, fire sensors, fire extinguishing systems, etc., whose market is limited. To conduct innovative fire extinguishing R&D on equipment that could dramatically improve fire-fighting efficiency, it is important to inform research institutions and private firms of the issues and needs in fire safety rather than to make efforts solely among organizations involved in fire safety and to conduct research by engaging a wide range of researchers from the pure sciences in practical technologies. The Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications set up a competitive research funding effort in fiscal 2003 called Promoting Program for Scientific Fire and Disaster Prevention Technologies (Competitive Research Funding Program) to promote R&D based on the collaboration of industry, academia, and the national government. This competitive research program solicits research proposals for promoting advances in fire safety and disaster preparedness science and technology and achieving safe and secure society. It involves researchers in industry, academia, and government and provides funding for proposals considered worth promoting. Some 104 studies had been completed under this program by fiscal 2014. The Kitakyushu municipal fire department, for instance, proposed developing a fire extinguishing composition able to extinguish fires using only a small amount of water. After building a system for collaboration with the University of Kitakyushu and local industries, they developed such a composition based on a natural surfactant whose use has greatly reduced the environmental load and whose performance meets the needs of fire-fighting operations conducted by fire department personnel in general fires. The team earned the Minister of Internal Affairs and Communications Award in the Fifth Merit Awards for Industry/Academia/Government Collaboration in fiscal 2007. In publishing the special issue on Fire and Disaster Prevention Technologies edited by Prof.Tomonori Kawano, Prof. Kazuya Uezu, and Prof. Takaaki Kato of the Research and Development Center of Fire and Environmental Safety, the University of Kitakyushu, it is shown that fire safety and disaster preparedness R&D undertaken by universities, local industries, and fire departments in Kitakyushu is proceeding on in an expanded scale. It is hoped that such undertakings and their findings will be extended to other areas, thus further promoting R&D in fire safety.

Рассмотрены этапы и направления создания и производства пожарных автомобилей (ПА) в современной России. Этот период отражен в виде четырех этапов. Значение 1-го 5-летнего этапа воспроизводства ПА после распада СССР (до 1997 г.) состоит в присоединении к двум старейшим предприятиям - изготовителям ограниченного ряда ПА еще шести предприятий с освоением новых типов и моделей основных и специальных ПА в количестве 55 ед. На 2-м этапе (до 2008 г.) создана нормативная база в виде норм пожарной безопасности (НПБ) по разработке, производству и испытанию различных классов ПА. Разработка Типажа ПА на 5-летний период стала базироваться на мониторинге потребности ПА территориальных управлений. В этот период сократились среднегодовые темпы роста освоения новых типов и моделей ПА, но улучшилось качество их изготовления, как с реализацией требований новой нормативной базы, так и за счет использования технологий и компонентов зарубежных производителей. С этого периода началось освоение производства ряда пожарных насосов и стволов нового поколения, которыми стали оснащать ПА. С введением в действие Федерального закона № 123-ФЗ начался 3-й этап создания и производства ПА. Разработана и внедрена нормативная база - национальные стандарты, определяющие классификацию, номенклатуру показателей и технические требования к ПА. Создан ряд типов и моделей ПА с инновационными составляющими. The article reflects the 4 time stages of creation and manufacture of fire vehicles (PA) in modern Russia after the collapse of the USSR. During the first stage until 1997 there were developed and mastered basic PA in the amount of 55 units meeting the needs of fire protection of the country at that time period. During the second stage until 2008 there was defined and created the regulatory framework in the form of fire safety standards (NPB) for the main range of fire vehicles for basic and special purposes. Data on the rate of manufacture of fire vehicles in comparison with the first period of manufacture are presented. There was mentioned the improvement of production quality with the use of new technologies and foreign experience in creating such models. When developing «PA Types» for a five-year period the monitoring of territorial departments of EMERCOM of Russia, which determines the need for a certain type and model of PA, has become important. The standard configuration of PA is defined by the order of EMERCOM of Russia. Since 2009 the third stage in PA creation has begun, taking into account the effect of Federal Law No. 123 dated June, 22 as well as the developed national standards for PA, which defined the classification, nomenclature and technical requirements for PA. The number of innovative models of these products were created during this period including: fire and rescue evacuation and tunnel vehicles, PA for operating conditions at temperatures up to below 60 °C, pump and hose systems, and others. The interstate standard GOST 34350-2017 (since 01.03.2019) is put in force during the fourth stage of the creation and production of PA in 2019.This standard defines the general requirements for basic PA and their test methods. The technical regulation TR EAEU 043/2017 (since 01.01.2020), reflecting the requirements for fire safety and fire extinguishing equipment, is put into effect at the same time. In 2019 with elaboration of draft of Concept for development of fire and rescue equipment until 2030 (2018), there is the beginning of new period that determined the most important directions for development of PA until 2030. The importance of cooperation between customers, manufacturers and scientific organizations in the field of creating effective fire equipment is noted.

Households are categorized as exceptions in the Fire Services Act; oftentimes, the ‘Golden Time’ is missed at the early stages of a fire, resulting in loss of life. As such, due to the high number of deaths caused by household fires, the Korean government amended the Fire Services Act to make it mandatory for all detached houses to be equipped with a fire extinguisher from 2017 onwards. Only 34.8% of households were properly equipped with a fire extinguisher, according to the 2018 factual survey on fire extinguishing facilities in households conducted by the Fire Department. Fire extinguishers are crucial in case of fire but many households avoid them because they are red and have a rough aesthetic, which does not suit the household environment. There is now a need for diverse simple fire extinguisher designs so that they can be used as interior décor in the household in the day-to-day while being available for putting out a fire when necessary. If fire extinguishers have designs that go well with any household space like other decorative ornaments, this will greatly increase consumers’ motivation to purchase them. It is greatly anticipated that various companies will work on developing designs for fire extinguishers to commercialize them for households in the future.

The results of a study on the extent, causes and measures of combating fires in churches in the north of the Tobolsk diocese in the XVIII - early XX centuries are presented in the article. Sources indicate “large” fires in Berezov and Surgut and few in rural parishes, and, as a rule, they indicate the destruction of church buildings and the futility of public efforts to prevent the fire element. The destruction of churches from fire is presented as a common cause of rebuilding of parish buildings in the 18th century. It is noted that the main cause of the fires was the careless handling of fire by church servants when burning stoves. Fire safety measures are characterized by the adoption of relevant legislative norms and administrative orders, monitoring of building codes and the repair of irregularities made during the construction of churches, and the spread of fire insurance. It is indicated that the state tried to involve not only the police, but also the population in the fight against fires. It is concluded that, despite the efforts made, the fire department in the territory of the region remained at a low level and did not allow to successfully confront the fire element.

Fostering sustainability is paramount for Smart Cities development. Lately, Smart Cities are benefiting from the rising of Big Data coming from IoT devices, leading to improvements on monitoring and prevention. However, monitoring and prevention processes require visualization techniques as a key component. Indeed, in order to prevent possible hazards (such as fires, leaks, etc.) and optimize their resources, Smart Cities require adequate visualizations that provide insights to decision makers. Nevertheless, visualization of Big Data has always been a challenging issue, especially when such data are originated in real-time. This problem becomes even bigger in Smart City environments since we have to deal with many different groups of users and multiple heterogeneous data sources. Without a proper visualization methodology, complex dashboards including data from different nature are difficult to understand. In order to tackle this issue, we propose a methodology based on visualization techniques for Big Data, aimed at improving the evidence-gathering process by assisting users in the decision making in the context of Smart Cities. Moreover, in order to assess the impact of our proposal, a case study based on service calls for a fire department is presented. In this sense, our findings will be applied to data coming from citizen calls. Thus, the results of this work will contribute to the optimization of resources, namely fire extinguishing battalions, helping to improve their effectiveness and, as a result, the sustainability of a Smart City, operating better with less resources. Finally, in order to evaluate the impact of our proposal, we have performed an experiment, with non-expert users in data visualization.

Purpose: To determine how often house fires occur at addresses visited previously for emergency medical services (EMS) and were these visits missed opportunities for a point-of-contact fire safety intervention.Method: Retrospective analysis of all Fire Department (FD) responses during 1994. Data studied with descriptive statistics: reason for response, property type, dollar loss estimate, injuries, fatalities, fire cause, smoke detector operation.Results: The FD responded to 94,378 requests for service at 43,556 addresses. 27,406 addresses generated one response. However, 16,150 addresses had multiple requests, receiving 66,972 responses. For the multiple requests, 1,162 addresses had a fire condition of which 728 addresses requested EMS prior to the fire condition. 215 were one/two-family dwelling addresses receiving 489 responses; mean 2.3 EMS responses prior to the fire condition. 182/215 (85%) of these addresses had complete data, incurring a dollar loss estimate of [US]$2,017,470, 33 injuries and 0 fatalities. The top five causes for the fire condition were children playing with smoking materials, arson, suspicious, scorched food and undetermined. 87/182 (49%) of the one/two-family dwellings had a smoke detector present. However, only 31/182 (17%) of the dwellings had an operational smoke detector.
