This study analyzed how the installation of a pressure gauge in the indoor fire hydrant of an apartment building affected identifying pressurized water in the pipe, making it easier to conduct internal inspection on the fire suppression system, and ensuring reliability of fire suppression. The following are the study's results: First, identifying pressurized water in the indoor firefighting pipe had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This implies that a higher level of identification of pressurized water in the indoor firefighting pipe had a positive impact on improving the installation and use of a pressure gauge in the indoor fire hydrant. Second, making it easier for the fire safety officer to inspect the fire suppression system had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This suggests that if it becomes easier for the apartment building's stakeholder to conduct internal inspection or the firefighting facility manager to carry out inspection on the fire suppression system, it would have a positive effect on the installation of a pressure gauge in the indoor fire hydrant. Finally, ensuring reliability in fire suppression had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This implies that if it becomes easier to identify pressurized water in the indoor firefighting pipe, for the fire safety officer to conduct internal inspection, or for the firefighting facility manager to carry out inspection in accordance with the fire suppression system's internal inspection requirements, it would increase reliability in fire suppression, making it more necessary to install a pressure gauge in the indoor fire hydrant.

Based on the problems of untimely Expressway fire rescue and backward traditional fire rescue methods, an emergency fire fighting and inspection robot riding on expressway guardrail is designed. The overall mechanical structure design of emergency fire fighting and inspection robot riding on expressway guardrail is completed by using three-dimensional design software. The target fire detection is realized by using the target detection algorithm of Yolov5; By selecting a variety of sensors and using the control method of multi algorithm fusion, the basic function of robot on duty early warning is realized, and it has the ability of intelligent fire extinguishing. The BMS battery charging and discharging system is used to detect the real-time power of the robot. The design of the expressway emergency fire fighting and inspection robot provides a new technical means for the development of emergency fire fighting equipment, and improves the reliability and efficiency of expressway emergency fire fighting.

Heat release characteristics of live fire load are an important parameter for performance oriented fire safety design of a building. While investigations have been carried out on the fire load and its burning behavior in office, residential and commercial buildings and so on, little effort has been paid for the rational treatment of fire load in bookstore. In this report, burning behavior of typical combustible objects in bookstore are studied by measuring heat release rates of bookshelf with book.

Previous research has explored early expression of fire signs before the burning of insulation. To achieve this, typically, automatic inspections are used to detect gas emitted from odor capsules at electrical connection points; additionally, early fire signs can be expressed using visual inspection of changes in the appearance of temperature caps. However, early detection of electrical fire is often difficult because only specific inspections, which are not complex, are performed. Therefore, in this paper, we present complex inspection techniques, such as visual inspection, odor inspection, and automatic inspection, and propose a showing material of fire signs that can solve conventional problems. In addition, this study examines the conditions under which the candidate material for the showing material is designed, the composition of the candidate material selected based on the designed conditions, the manufacturing means used to produce the showing material considering the temperature for early expression of fire signs, and the performance of the produced showing material. Furthermore, we analyze various effects that can occur through the proposed display material.

This paper presents a quantitative analysis method to quantitatively indicate a electrical fire preventive effect of safety inspection for electrical facilities for general use. Logic model was developed based on whether enforcement of safety inspection for electrical facilities, and then the developed analysis model was converted to hydraulic model by using mathematical logic. The electrical fire preventive effect of safety inspection for electrical facilities was quantitatively calculated by applying electrical safety inspection results and fire statistics for five years to the developed hydraulic model. The results show that electrical fire preventive effects of 5,542 cases on annual average for five years.

This research analyzed the operational status of fire protection system managers who execute self inspection of the fire equipment in the specific fire protection facilities and presented the improvement scheme. Being made up inquiry for job environment, institutional environment, and operational environment for the subject of fire protection system managers who execute self inspection to complement the fire equipment inspection by city public fire protection service, the issues of the operational status of the institution of fire protection system managers were positively understood. The research result showed the conflict among building owner, fire equipment inspector, and fire protection system manager was existed due to the legal and institutional inertia to the self inspection, so it is judged that mutual complementary and cooperative relation should be established.

Manpower will need to be increased to conduct special fire inspections. The aim of this study was to predict the manpower required. According to the estimate, 20,332 inspectors will be needed to conduct special fire inspection on a two-person team basis for a year. If the entire object is to be inspected for five-years, it will be inspected at 20% per year. The currently manpower is not enough to inspect all the objects, which will result in a poor inspection. Therefore, the adoption of a full and partial inspection system will be considered. If 10% full inspection and 10% partial inspection will be conducted, 2,734 inspectors will be needed, whereas if 2% of full inspection and 18% partial inspection are conducted, 1,669 inspectors will be needed.

Modern constitution obtains its justice by protecting the people's basic legal rights. The constitutional rights can be more than a defensive measure against government power by modern viewpoints. The government has to create an atmosphere which the rights are not violated. The Constitution provides that the government has to make efforts to prevent disaster and protect the people from danger in Clause 34, Art. 6. The government has an obligation to protect the people's basic legal rights of life, health and property from fire damages, and those rights are gathering strength under a socialist state principle as fundamental ideology of modern societies. The present fire inspection system gains a point constitutionally but it still needs to be certified as the most suitable system. This article examines the solution to operate fire inspection system efficiently, given the reality of present system operation. It is necessary to improve the system by integrating the present fire inspection with the self fire inspection. Government needs to re-modification the Fire inspections system for prevent and promote (resolve) the problem which government officer (ex fire fighter) can make a irregularities and corruption as do it oneself.
