Analyzing electrical singularities using X-ray analysis equipment of fire investigation vehicles arrived to the fire site can be useful as it can quickly determine the source of ignition through arc mapping analysis at the site. In addition, in the case of non-destructive inspection using X-ray, melted material such as PVC is melted so that it cannot be disassembled, or fire ignited by LED elements with high risk of damage to the original, In the case of multi-socket, it is useful for determining the firing point, where tracking occurs at the connection part which is connected by the power lines. And secondary short-circuit marks are formed by flames. When evidence is collected and requested to an appraisal agency, the reliability of the collected evidence can be further increased by attaching the X-ray nondestructive test result before disassembly. It is very important to secure physical evidence that is the basis for identification for a comprehensive conclusion at the fire scene. In addition, it is important to detect electrical singularities immediately using the X-ray of the fire investigation analysis vehicle at the fire site and to link the analysis in the analysis room.

Currently, various systems applicable in the field of fire fighting have been developed. However, fire investigation does not have a system that can be applied or referred to in the field, and it relies only on the qualities of fire investigators. It is intended to develop an on-site fire investigation system by referring to big data in the field of fire investigation accumulated for decades and introducing the latest technology, Metabus. If a system-based fire investigation is established, universal standards are applied across the region and the data can also be reliable. The system is made in the form of an app and installed on a tablet or mobile phone for use. If the contents of the basic fire investigation are entered in the app, and the person concerned is a foreigner, the statement can be secured using the interpretation function. The survey report may be inquired at the site and used as a reference material, and necessary information such as the status of buildings may be referred to. In order to calculate the amount of damage, reliability can be improved by referring to system-based data without having to memorize the law separately. Now, fire investigation systems (apps) available on the site will be required, not optional, in fire investigation. Also, whoever is in charge of fire investigation can conduct basic fire investigations if they only know how to use the system.

Recently, interest in insulation functional building materials has been increasing to reduce greenhouse gas and increase energy efficiency. However, insulation materials installed in buildings for insulation cause the rapid vertical spread of flames, and it causes difficulties in extinguishing fires, leading to enormous casualties and property damage. Therefore, the purpose of this study is to identify the diffusion characteristics of flames according to the type of insulation and adhesive, and to establish measures to reduce fire damage. To this end, different types of insulation and adhesives were used to compare the diffusion characteristics of flames by simultaneously setting fire. In conclusion, only incombustible insulation had the effect of preventing combustion expansion, and flame retardant insulation and semi-incombustible insulation had minimal effects. And no difference was found according to the type of adhesive. Therefore, it is necessary to revise the current building regulations to restrict the use of combustible insulation materials and to mandate the use of non-combustible insulation materials.

There are many powdery things in all spaces, including houses. Dust can be thought of as lightly as dust flying around, but it is a very small solid particle if you think broadly. These dusts are exposed to danger as they are easily accessible. It demonstrates the danger of dust caused by wire sheaths that always exist in living spaces during various dusts, and warns firefighters to safely extinguish fires at fire sites in preparation for dust explosions when extinguishing fires..

This study seeks to expand the area of fire safety services to the public by establishing a firefighting colleague psychological support system for firefighters and a disaster psychological support system for the public. we examined the National Fire Agency's mental health support policy and the status of PTSD(posttraumatic stress disorder) management among domestic and foreign firefighters. In addition, as a result of analyzing the effectiveness of the firefighting colleague counseling and the operation cases of the Central Firefighting Psychological Support Group, it was confirmed that it has a positive effect on the mental health management of firefighters. In order for the Central Fire Protection Psychological Support Group to develop into a focal point for not only the mental health of firefighters but also the mental health of disaster victims, it is necessary to establish a legal basis and to reorganize the systematic organization and budget. Additionally, programs to foster internal experts are desperately needed. The results of this study are intended to contribute to boosting firefighting morale and expanding the scope of firefighting activities by discovering disaster psychological support policies for firefighters.
