고용노동부의 산업재해 사고사망 통계에 따르면 건설업의 사고 사망자는 458명으로 사고사망자의 77.3% 가 50세 이상이며, 41.9% 가 60세 이상 고령층인 것으로 나타났다. 본 연구는 건설현장에서 근무중인 고령근로자 68명을 대상으로 안전교육, 보호구, 안전의식에 대해 파악하고자 설문조사를 진행하고 분석하였다. 그 결과 고령 근로자들이 가지고 있는 모순적인 안전의식을 재고하기 위해 시각자료를 활용한 안전 교육의 다양화의 필요성에 대해 확인하였다. 또한, 보호구에 대한 높은 필요성 인식과 현장 착용에도 불구하고 보호구 착용에 소극적인 근로자를 위한 개인 신체에 맞는 보호구 지급과 주기적인 교체 등의 보호구의 개선의 필요성에 대해서 확인하였다.

Middle domestic the occurrence size which stews recently from the Korean Peninsula circumference country is augmenting on a large scale about earthquake about safe countermeasure part from the existing Natural Countermeasure Law 2008. Refers with the Earthquake Disaster Countermeasure Law to be new standard contents establishment by law and strengthened in March. Consequently the research is propelled about electric equipment earthquake-proof plan and countermeasure. The present paper investigated an equipment by domestic facility present condition about the change disappointment electric equipment which can supply all the member in the building an investigation analysis about problem point and improvement fact. Also about overseas electric equipment investigated about earthquake-proof plan relation system and facility present condition. Investigated the electric equipment earthquake-proof plan pertinent data which is advanced from like this existing nation and the equipment and application direction must apply to domestic presented. With character presents following the guide about electric equipment earthquake-proof plan becomes feed with the fact that will be able to use.

Purpose: To attain advanced performance certification, safety aspects along with functionality and performance are essential. Hence, this study suggests radiation leakage assessment methods for aviation security equipment during its performance certification. Methods: Detection technology guided the choice of radiation leakage assessment targets. We then detailed measurement and evaluation methods based on equipment type and operation mode. Equipment was categorized as container or box types for establishing measurement procedures. Results: We've developed specific radiation leakage assessment procedures for different types of aviation security equipment, crucial for ensuring airport safety. Using these procedures allows efficient evaluation of compliance with radiation leakage standards. Conclusion: The suggested radiation leakage assessment method aims to enhance aviation security and reliability. Future research will focus on identifying risks in novel aviation security equipment detection technologies and establishing safety standards.

Photovoltaic and Thermal collector (PV/T) systems are renewable energy devices that can produce electricity and heat energy simultaneously using solar panels and heat exchangers. Since PV/T systems are exposed to the outdoors, their reliability is affected by various environmental factors. This paper presents a reliability test for a PV/T system and evaluates the test results. The reliability assessment entails performance, environment, safety, and life tests. The factor that had the greatest influence on the life of the system was the hydraulic pressure applied to the heat exchanger. A test was conducted by repeatedly applying pressure to the PV/T system, and a reliability analysis was conducted based on the test results. As a result, the shape parameter (β) value of 5.6658 and the B10life 308,577 cycles at the lower 95% confidence interval were obtained.

The leisure life pattern of people is changing to a familial and enthusiastic way that eventually develops the camping culture. Thus, the number of campers and the size of camping market have been dramatically increased due to significant expansion of camping people. However, many camp grounds and facilities are operating without a proper registration by government rules and regulations. In addition, many of electronic and gas equipment and tools are not used in a safe way and in a safety regulatory boundary. Therefore, campers at the camping ground is situated in a fire and safety hazard. In addition, there is limitation in rules and regulations associated with camping ground safety and fire. This study analyzed the fire and hazard guidelines and rules regulations of developed countries of campground and compared them to the current situation in South Korea. Therefore, this study is to develop a safety and fire hazard guidelines and rules and regulations related to camp ground operation, gas and electronic equipment operation and management. The study will eventually reduce the future fire and safety incidents in a campground in South Korea.

This paper describes how to ensure safety of train by guaranteeing stable and continuous communication in RF-CBTC. CBTC System uses the wireless communication between onboard and wayside so that safety of wireless communication is the most important. Losing the position of train causes vital problem of train service. By losing the position of train, the other trains are blocked in the block and the train move by emergency mode so headway and safety cannot guaranteed. Therefore, safety is ensured by redundancy of wireless equipment. One of the ways to make redundancy is redundancy of equipment. However, the redundancy of equipment spends a lot of money to avoid interference in limited place like underground. Continuous communication is guaranteed by means of redundancy of wireless communication coverage to solve the problems even though one of the equipment is broken.

The purpose of this study is to attempt a Analysis of a pointed-end Equipment Arm Safety-Accident for Fault Tree Analysis. Three major techniques were used first problem is Z-Model by which accident Analysis & prevention of a pointed-end Industry can be made, Fault Tree Analysis(FTA) bywhich quantification of a pointed-end Equipment accident Analysis can be made it 5 years in past and the third, manual-written by which minimal cut set to accident can be Identified. A example has been made of issue point a pointed-end Equipment that the Arm in loader happen to Injuries. According to the Analysis lack of safety knowledge, unsafety-behavior seem to be the primal cause of accident. Comparision of the accident cause to actual report demonstratesthat the FTA a efficient tool for Industrial Accident prevention.

In this study, S food manufacturing business located in Chungbuk was selected as the subject, and the transition in insulation resistance in major electrical equipment used in this food manufacturing business was analyzed for 4 years (2018-2021). It was confirmed that the insulation resistance decreased over time for all 18 electrical facilities. Insulation resistance changed due to environmental influences such as load characteristics and ambient temperature. Particularly in the case of the food manufacturing industry, it was confirmed that the decrease started after 2 years, although it varied depending on equipment and environmental influences. Furthermore, it was confirmed that management through predicting the management cycle of electrical equipment is possible by deriving a regression equation through regression analysis of insulation resistance measurement values.

This study is to prepare a reasonable basis for the improvement of the electrical safety management regulation. The standards in domestic and foreign countries for the application of new and renewable energy facilities and other devices are analyzed. Other regulations excluding the electrical safety fields and wide surveys are also carried out. Consequently, it is asked that the classification between normal and self electrical facilities should be clear and deregulation for small businesses has to be followed. This study is showed that standards investigates of receiving equipment below 600V above 75kW, eletrical safety manager employment of manufacturing industry and Mid-night electric power. And, it is showed that consignment permission and Consignment inspection periodic relaxation about wind development equipment below 1,000kW, consignment of Technical Development equipment for new and renewable energy below 250kW.
