| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災技術研究所 === 90 === The frequent occurrence of major fire accidents caused tremendous loss of lives and properties in this country. In order to reduce the occurrence and prevent the fire hazards, the government needs to advocate the knowledge of fire prevention and implement effective fire-fighting strategies in addition to changing laws and regulations and promoting public safety plans.
This study includes the analysis of contributing factors of electrical fires of aged and deteriorated electrical wiring, the investigation of electricity usage of old residential buildings, and the test of electrical wires. According to this investigation, the fire hazards of old residential buildings are mainly the frayed or faulty electrical cords and outlets, the careless use of extension cords, the improper connection of electrical wires/sockets, and the use of frayed wires. These are the major factors that triggered electrical fires of old residential buildings. In the electrical current test, it was found that the aged and deteriorated electrical wires carried less current safely then the equivalent brand new electrical wires (about 90%). Therefore, this study provides suggestions in terms of regulations and disaster factors to prevent electrical fires and reduce the occurrence of electrical fire accidents.
