Dalam pembangunan sebuah gedung terdapat suatu utilitas keamanan salah satunya adalah sistem instalasi sprinkler yang dirancang sesuai dengan standar proteksi kebakaran yang disiapkan untuk mencegah, memadamkan dan menanggulangi kebakaran dalam bangunan gedung. Pada perencanaan sistem sprinkler ini bertujuan untuk memahami dan melakukan perhitungan pada kecepatan aliran dan tekanan serta merencanakan kebutuhan air pada pemadaman fire fighting gedung hotel. Penulis melakukan penganalisaan dan perhitungan dengan menentukan discharge coefficient of the sprinkler k-factor pada kecepatan aliran fluida, selanjutnya menggunakan presure loss dari Hazen-Williams dan dilakukan kebutuhan air dengan mengacu pada Azas Bernoulli, yang penulis sebut dengan metode Step by Step. Dari hasil perhitungan ini didapat bahwa hubungan antara kecepatan aliran pada sprinkler otomatis ini dengan pressure loss yang terjadi dipengaruhi oleh area yang direncanakan, diameter pipa yang digunakan serta panjang pipa. Dimana perencanaan ini mengacu pada standar yang berlaku seperti Standar Nasional Indonesia (SNI) dan National Fire Protection Association (NFPA) yang harus dipakai dalam perencanaan siste sprinkler otomatis pada sebuah gedung.

In only ten years, high pressure water mist fire protection has evolved from theory to becoming widely accepted as an alternative to traditional sprinkler systems, foam, CO2, halon, and other gases. It has proven itself as offering equal fire protection efficiency to these other systems and, in many conditions, exceeding them.

Installation of ancillary facilities such as electrical rooms is crucial due to the complicated structure and division of the interior of a complex building. Furthermore, carbon-dioxide extinguishing systems are mainly installed in these ancillary facilities, and the number of systems installed has been increasing annually. Accordingly, the importance of in-house inspection is being emphasized. In this study, the literature and statistics related to the in-house inspection of fire-fighting facilities were reviewed. Based on the results, problems were derived from the overlap between in-house inspection and similar inspection, the installation location of the pressure switch, the installation standard of the air respirator, the safety awareness of people involved, and the technical qualification level of the in-house inspection assistant. Additionally, improvement measures to enact, amend, and establish public notices were proposed for self-inspection systems.

Introduction. Rationale of the topic of this article is the need to improve the effectiveness of fire detection. One of the modern solutions to this problem is the use of video technology. The article is aimed at developing a method to assess the effectiveness of video surveillance in the fire protection system on the basis of the formed mathematical model.Methods of research. The fire risks theory is used for formation of mathematical model. The potential fire detection risk is introduced as a quantitative measure of the possibility of undetected fire occurrence at the protected facility, development and implementation of its consequences for people and material valuables. It is calculated as the product of the maximum probability of fire by the probability of its non-detection by the technical means and alarm systems used. The efficiency of video surveillance use in the fire protection system is determined on the basis of compliance of the complex risk index of fire non-detection with the permissible value.Research results. The possibilities of increasing the efficiency of fire detection through the use of video technology are considered. Reducing the fire detection risk can be achieved by using video channel fire detectors that reduce the time it takes to reliably detect a fire. The probability of reliable detection is an important parameter of the detector during its operation in the fire alarm system and characterizes the degree of performance of its main function. The main ways to improve the efficiency of fire detection are the improvement of fire detectors with video channel, the joint use of fire video detectors and other detection devices, such as automatic multi-criteria detectors, thermal imaging сamera, as well as the use of photo and video in centralized surveillance systems.Conclusions. The offered method of estimation of efficiency of application of video surveillance in fire protection systems can be used for a substantiation of parameters of technical means (systems) of the fire alarm system and passive fire-fighting measures established on the facility.

В статье исследуется деятельность Владимирского и Рязанского земств по укреплению и распространению противопожарных мер в конце XIX — начале XX века. После Великих реформ 60–70-х годов XIX века необходимость борьбы с пожарами легла на плечи органов местного самоуправления. Рассмотрены вопросы о распространении огнестойкого строительства, о рытье колодцев и устройстве прудов, запруд, плотин. Отдельно проанализирован процесс распланирования селений, приводятся статистические данные о пожарах по Рязанской и Владимирской губерниям. В статье отмечается важная роль, которую сыграли органы местного самоуправления в деле распространения противопожарных мер. Делается вывод, что самыми общеупотребительными противопожарными мерами во Владимирской и Рязанской губерниях являлись распланирование селений, сооружение огнестойких строений и крыш, посадка деревьев, устройство искусственных водоемов и колодцев. The article investigates the measures undertaken by the representatives of the Vladimir zemstvo and the Ryazan zemstvo to enhance anti-fire activities in the late 19th — early 20th centuries. After the Great Reforms of the 1860s–1870s, the task of fire fighting was imposed on local authorities. The article treats the issue of fire-resistant building construction, construction of wells, ponds, and dams. The article analyzes the process of fire protection engineering, provides statistical data on fires in the Ryazan province and the Vladimir province. The article maintains that local authorities played an important role in the implementation of fire prevention measures. The author concludes that the most common fire prevention measures in the Vladimir province and the Ryazan province included the construction of fire-resistant buildings and roofs, tree planting, and the construction of water reservoirs.

Regulation of the Minister of Interior and Administration of 7 June 2010 on the fire protection of buildings, other construction objects and areas, presents a number of requirements that must be met by public buildings and residential buildings requirements, among others, for fire-fighting water supply installations. The article presents an analysis of current requirements for water supply installations in public buildings and residential buildings included in Polish legal acts. In addition, statistical data on the size of the fire are presented and real water consumption in the activities of fire protection units during events. These data were obtained from the SWD PSP program, which is the basic tool for supporting the actions of rescue and fire-fighting units. It turns out that for the objects in question statistically the largest amount of fires are small fires, where relatively little water is used. On the basis of the comparison of the actual water consumption needed to extinguish the fire by the fire department with the requirements in force in relation to the analyzed buildings, too restrictive requirements for these facilities were noticed. Appropriate efficiency of the external hydrant network ensures the possibility of carrying out extinguishing activities. In connection with the above, one should consider the legitimacy of applying high requirements for the efficiency of fire protection installations in facilities.
