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.

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.

Education Satisfaction

The purpose of this study is to investigate the effect of apartment residents’ safety education satisfaction and the application of fire protection plans on fire safety awareness. The analysis results are as follows. First, the low levels of satisfaction with safety education content had a negative effect on anxiety about fire safety. This means that apartment residents’ low levels of interest or participation in education affected their safety awareness, which prevented them from securing safety from fire. It is necessary for control staff to have a positive impact on their educational satisfaction via the learning support information system, among others, in order to create a satisfying education and safety culture. Second, competence in the execution of firefighting plans had a positive effect on fire safety awareness. These results indicate that apartment residents do not have the opportunity to access the education and training necessary for safety, nor the legal responsibility to complete mandatory safety education, which leads to their lack of safety awareness. Therefore, the control staff need to raise awareness of fire safety and the importance of participating in safety education among apartment residents by strengthening and activating the execution of firefighting plans in order to ensure safe living. Third, the competency of the firefighting plans moderated the effects of apartment residents' educational satisfaction on their awareness of fire safety.

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.
