The construction of high-rise buildings has revealed new problems related to fire safety. The peculiarity of the architecture, which is covered in high-rise, in fires creates a danger for a large number of people there, reduces the possibility of their evacuation and rescue. The multifunctionality of such buildings, taking into account the originality of the external and internal views, leads to the difficulty of choosing a constructive system, a large number of utilities and technical systems. To address the issues related to safe operation, stay and evacuation of people is the development of a fire protection system for high-rise buildings, based on the development of: • measures to ensure the durability of buildings or parts thereof againstprogressive collapse due to * ensuring the fire resistance of structures and buildings; • measures to limit the spread of fire in high-rise buildings through theinstallation of fire barriers inside the building and the device of fire breaks between buildings; • measures for ensuring timely and unimpeded evacuation of people andtheir rescue at emergency in high-rise buildings; • systems of active protection of buildings from fire, namely: fire alarm andfire fighting, strong points of fire extinguishing.

Problem. Religious buildings with a large number of people are fire hazardous. In total, there are 17,407 religious buildings in Ukraine. Out of them, approximately 3,000 are highly fire hazardous wooden buildings.The fire danger feature of religious buildings is open fire usage: candles, torches, lamps, underground rooms with complex planning, lack of ventilation systems. Besides, ancient religious buildings are mostly built using wooden materials. Fires occuring there are resonant, causing material and spiritual damage to the state and society. On average, about 20 fires occur each year in religious buildings, including wooden temples of historical heritage.Рurpose. Fire analysis in religious buildings in Ukraine and their occurrence causes; fire safety of religious buildings research.Preventive measures for religious building fire safety in Ukraine are prioritised by state program for emergency response. The State Emergency Service of Ukraine constantly monitors compliance with fire safety standards, which includes regular facilities inspections, personnel training control to prevent fires and reduce the consequences of fires, development, implementation, and control of technical methods of safety.Research methods. To achieve this goal, further methods were used: historical, systemic, theoretical generalization, abstract, logical, analysis, synthesis, comparative, and statistical methods.The main results. The most common shortcomings in religious building fire protection are the lack or malfunction of automatic fire alarms, power grid requirement non-compliance with the rules of the power grid, improper facility provision of with primary fire extinguishers, lack of lightning and water supplies for firefighting. In most buildings, wooden structures are not treated with refractory mortar.Fire causes and ways to prevent and improve fire safety are analyzed, namely: fire protection of religious building wooden elements, dome space fire extinguishing systems, fire alarm systems, lightning protection, safe people’s evacuation, candlesticks installation on non-combustible surfaces, primary fire extinguishing equipment, fire condition qualitative inspection of the of the heritage building, etc.Conclusions. After service, buildings must be completely deenergized, lighted candles and open fires must not be left unattended in the church. In religious buildings, it is necessary to carry out fire protection of wooden elements constructions, to install fire extinguishing systems in domed space, fire alarm system, lightning protection, to watch serviceability of electric networks. Rules of fire safety requirements for religious buildings are aimed at solving an important task - religious buildings safety. Unfortunately, due to lack of funds, the most important requirements are not implemented to improve fire safety.

Introduction. The fire safety of the protected object is determined by the possibility of reliable fire detection. Insufficiently effective operation of the fire alarm system can lead to the death of people, unacceptable material and other damage. The video surveillance system, being one of the main links of the engineering security system, monitors emergency situations in real time and, in particular, a breakout of fire at the protected object. Goals and objectives. The purpose of the article is to analyze the state and trends in the development of video surveillance equipment aimed at improving the fire safety of protected objects. Tasks include regulatory justification of the use of video surveillance in fire alarm systems, review of methods of fire detection by video surveillance and improving their effectiveness under the influence of interfering factors, as well as evaluation of the effectiveness of video surveillance in fire protection systems. Methods. The methods of the system analysis and probability theory are used. Results and discussion. The requirements of regulatory documents for detectors with a video detection channel for their effective operation in fire alarm systems are considered. The main directions of development of means and methods of application of video surveillance in fire protection systems are defined. It is shown that reducing the risk of non-detection of fire to an acceptable level can be achieved by increasing the probability of effective operation of the fire alarm system, as well as by increasing the positive impact of the video surveillance system, which is a part of the complex security system of the object. Conclusions. Video surveillance significantly increases the efficiency of fire detection. It allows you to get a visual picture of the state of the protected object, which has such a high information content that no other security means can provide. The use of video surveillance equipment in fire alarm systems, as well as their integration with industrial and fire automation systems is one of the main reserves for increasing the fire safety of facilities.

Over the last year, the number of new buildings in Lviv has increased by 30%. Most of them are the high-rise buildings. In this regard, the problem of fire safety of such buildings appears sharper. In our time, one of the main requirements in building standards is to ensure the life safety. Fire safety is an integral part of the life safety. The main causes of the fires, difficulties of their liquidation, the problems of self-management, the reliability of the systems of fire water supply, fire barriers and the evacuation of people from high-rise buildings were analyzed in the article. The causes of the rapid spread of fires in multi-store buildings were revealed. The analysis of the example of fires clearly shows problems of fire safety, admitted at the stage of construction of the high-rise buildings. The actual situation in such buildings is characterized by the following disadvantages: the fire alarm system often is in an unfit condition because of dismantling of the fire alarm sensors by the residents; the common floor-corridors are blocked by additional partitions, causing difficulties in the work of the smoke exhaust systems; there are no self-closing doors and their sealing in the shelters, which allows smoke to spread freely in the house and creates the preconditions for rapid vertical fire spreading. The protection of people on evacuation routes is provided by a complex of planning, constructive, engineering, technical and organizational measures, such as smoke protection, proper fire resistance and fire propagation limits of the structures, providing and proper decoration of evacuation routes, smokeproof stairways, annunciator systems, etc. Therefore, introducing of fire safety systems in high-rise buildings is a priority task at the stage of their designing, construction, and operation.

High-rise (HR) building fires remain a tragic cause of preventable injury and death in the United States. Recent incidences of HR building fires have served as high-profile reminders of the persistent threat that HR fires pose to public health. Fire safety is an important aspect of household emergency preparedness addressed by community/public health nurses (C/PHNs). This study aimed to address a gap in the literature regarding C/PHNs’ awareness of fire safety for people and families who reside in HR buildings. A descriptive qualitative study using key-informant and focus group interviews was conducted involving C/PHNs ( n  =  19) in Honolulu, Hawaii. Qualitative data analysis revealed three main themes related to this issue: (1) C/PHN awareness of HR fire safety issues, (2) C/PHN perceived barriers for HR building occupant fire safety, and (3) C/PHN suggested strategies to address HR fire safety for occupants. Findings highlight how more needs to be done to assure that C/PHNs are adequately prepared to work with occupants of residential HR buildings on matters related to fire safety.
