In this study, the fire safety standards for windows in Korea, the United States, and Japan were compared to prevent fire expansion through exterior wall openings. Experiments on polyvinyl chloride (PVC) and aluminum window frames widely used in Korea were performed. The tests were conducted according to KS F 2845, in which frames with equal thickness and area in a single-window form and 1 h fire-resistance glass with an 8 T thickness were combined. The experimental results showed that the PVC window was approximately 9 min, and the aluminum window was approximately 26 min. However, in Korea, there are no test standards for windows installed at the opening of exterior walls. In addition, fire safety standards for windows should be established along with designations of fire prevention zones.

We introduce an open-source software for fire risk assessment named Aamks. We provide a brief overview of the following aspects of the platform: the motivation for creating Aamks, the architecture of the platform, the user interface, the intended workflow for conducting fire safety analyses, the probabilistic approach to fire risk assessment, the geometry processing, the reasoning from the topology of the building (i.e. automatic planning of exit routes), the interactions amongst the moving evacuees, the impact of smoke on humans and finally the results and the visualization.

The fire risks of spreading trends and spreading processes of Underground Commercial Street were digitalized in this work combining with the analog of the ‘infection propagation’ model, and a dynamic fire risk model was established with the consideration of fire risk flow. This investigation will provide effective data support for the initial planning, designing and fire prevention in various stages of Underground Commercial Street.

Assessment Of Compliance

This article presents the results of the assessment of compliance with fire safety requirements of the building of the poultry house for 200,000 heads of Avangard LLC of the Republic of Mordovia, made on the basis of fire risk calculations. The analysis of factors affecting the quality and reliability of the results of calculations is carried out. During the research and evaluation of the objects compliance with fire safety requirements were guided by the provisions of the Technical regulations on fire safety requirements. A list of technical regulations applicable to the object under study was defined. The article gives the fire-technical characteristics of the object under study, the class of functional fire hazard (agricultural buildings). The conducted research has established that the object of research meets the requirements of fire safety. Calculations on fire risk assessment were fulfilled by comparing the calculated values of fire risk with the normative value. For the considered object of protection the fire hazard analysis including the analysis of building characteristics (space-planning, design and technical solutions), fire protection systems, and features of functioning taking into account contingent and distribution of fire load in rooms was completed. The calculation of the risk of the gas supply system was considered the impact of the flame during the combustion of gas released in case of emergency depressurization of the pipeline. The potential risk in a poultry house near a gas pipeline with a diameter of 50 mm will be 1.7810-5, near a gas pipeline with a diameter of 70 mm - 4.410-7, and in total - 1.82410-5. The individual fire risk for employees of the poultry house building is 8.3110-7 year-1. Calculations of the spread of fire hazards and the time of evacuation of people are made using software that allows to create graphical models of space-planning solutions of buildings. With the introduction of the fire risk assessment system at the legislative level, the owners of objects have the opportunity to optimize the cost of fire safety with the required level of safety of people.

Aim.The development of the Russian railway industry is associated with the growing number of operated buildings, rolling stock, more complex business processes of infrastructure maintenance and client service. In this context, JSC Russian Railways (JSC RZD) needs to manage the fire safety of more than ten thousand units of traction rolling stock and hundreds of buildings, where potential fires may cause harm to passengers or interruption of service. Fire safety management of both fixed and mobile railway facilities is performed at all lifecycle stages from design to disposal. Implementing the processes of fire safety diagnostics and prediction requires the development of a man-machine system whose core would be an automated fire risk control system (ACS) that allows – basedon the fire risk prediction – makingdecisions regarding the requirement for the repairs, replacement or maintenance of railway facilities and fire safety systems. Methods.The methods of the automatic control theory, expert assessment were used. The study aimed to develop an algorithm of automated auditing of railway facilities fire safety. Results.It is established that the majority fire safety control systems use gas concentration sensors to detect symptoms of hazard before flame development. This approach is hardly effective in terms of fire safety of railway facilities. For railway facilities whose actual state has an effect on the probability of fire a fire audit algorithm was developed that is based on the existing service and repair system, as well as statistical data on the states of railway facilities that precede fire. In order to enable systematic risk management measures in a large number of railway facilities, the paper proposes the structure of an automated fire risks management system that includes a fire safety management center and a mobile hardware and software system for fire safety auditing. Conclusions. It shows the importance of developing a proactive fire safety management system based on fire risk assessment. It was identified that information on the states preceding fires in railway facilities can be obtained from both the existing automated failure reporting and risk assessment systems and the diagnostic results of the actual state of objects as part of scheduled preventive maintenance. A method of automated assessment of fire hazard is proposed for systematic management of fire risks in many railway facilities.

There are approximately 290 million blind people worldwide. Among them, approximately 40 million people are severely blind. Although systems and policies have been improved to enhance the convenience of the visually impaired, the standards related to evacuation safety in the case of fire have not been sufficiently improved. Therefore, in this study, to ensure the safe evacuation of the visually impaired in case of fire, domestic fire safety standards were derived by analyzing the development status of a domestic barrier-free system and related manuals based on the characteristics of evacuation behaviors of the visually impaired, as well as by reviewing the cases in the United States and the United Kingdom. As a result, the following measures were derived: 1) improving the display method for landmark elements, 2) customized fire safety education and training for employees, and 3) a plan to develop a personal emergency evacuation planning manual in accordance with the characteristics of a building. It is expected that these objectives can be used to improve fire safety standards and manuals and to develop related technologies for the visually impaired.
