A roadmap for Electrical Safety Technology has been designed based on the study that has been contributed by the specialists, professors and researchers in electral safety field. The roadmap is divided into five major fields including, for instance, the electrical fire accidents roadmap. The other four roadmaps are for electrical shock accidents, electrical facilities accidents, electrical safety policies and electrical safety culture-education, respectively. Each roadmap has a purpose, a scope, and a technical characteristic. Following the roadmaps can result in significant reduction of electrical fire accidents, electrical shock accident victims and so forth. The result can also be utilized in guiding the planning and development of the future electrical safety technology.

As the industrial scale is getting enlarged and the people's quality of life is growing, the electric energy consumption has been rapidly increasing every year and the frequency of electrical accidents such as electrical shock This paper gives statistical analysis of the number of casualties caused by the electrical shock, five hundred people every year, but it still exceeded the shaping risk of electrical accidents to anyone in KOREA. In this paper, for the electrical shock of the in 2014 act by occupation, voltage electrical equipment, location, accident type and months. In order to acquire electrical shock in 2014, we visited police stations and hospitals and analyzed records of accidents. The result showed that the electrical shock alone caused 37 people deaths and 569 injuries.

According to the data of Korea Occupational Safety and Health Agency, electric shock accidents during recent 11 years exceeded more than 60% in architecture/other and construction work, the countermeasures for safety are required in the harsh environment of a construction site where moving electric machines and equipments are widely used. The establishment of countermeasure for insulation degradation and defect is required, in consideration of increasing trend for accidents caused by defective insulation among low voltage electrical installation each year. The aim of this study is to propose the policy about portable electrical tool standards and/or worker's safety standards for preventing electric shock accidents on safety workings, and is to develop the technology and the safety device to prevent electric shock for accident prevention reduction through experiments. It obtained the followings through this study; statistical data analysis of late about 10 years of electric shock-related industrial accidents analysis and portable electric tools; safety device development of 'device for testing continuous grounding and power shut-down' to prevent electric shock from portable electric tools. Furthermore, developed results and proposal in this study will help to prevent the electric shock accidents from portable electric tools and will be expected the utilization of policy formulation, educational data and field supplement of the safety device, and etc.

This paper has analyzed various aspects of electric shock accidents on th base of the published statistical data of the Ministry of labour between 1982 and 1990. The number of electric shock accidents has suddenly been increased in 1990, because of the booming business of the building construction. It was found that many temporal electric wirings and movable electric devices in the field of construction have bee na leading cause of the electric shock accidents. In order to reduce the rate of electric shock accidents the proper authorities will have to establish the safety measures, to educate workers to prevent the accidents and to supervise more carefully.

This paper describes electric shock accidents on a 4.16 kV class circuit breaker for power plant. Electric shock accidents mostly involve damage of human life, in comparison with electrical fire, rate of human death tend to be higher in electric shock accidents. Specially, in a high voltage facilities rate of human death comprised about 43.7% by electric shock accidents. If electric shock accidents happen in a 4.16 kV class circuit breaker for power plant, then the power plant discontinue power production. Electric shock accidents in a power plant have a great ripple effect such as an electric power shortage. In this paper, we analyzed electric shock accidents on a 4.16 kV class circuit breaker for power plant. From the analysis results, we confirmed a cause of electric shock accidents on a 4.16 kV class circuit breaker, it happened by defect of interlock equipment or occurrence of breakdown between first feeder contactor and shielding plate. In order to reduce electric shock accidents on a 4.16 kV class circuit breaker, the power plant should consider improvement of interlock equipment and insulation of feeder contactor in circuit breaker.

Unlike conventional transmission and distribution lines, catenary system for operating electric railway vehicles are composed of multi-conductor groups (feeder line, contact wire, messenger wire, protection wire) and are used for railway employees, public or passengers in the station yards. Electric shock hazards are exposed and electric shocks such as death or serious injury are occurring in electric railway vehicles, railway high-voltage distribution lines, and catenary system. In order to analyze the types of electric shock accidents on railway by systematic approach method, we modeled 'unsafe behavior classification' method using swiss cheese model. Based on this method, we derived the type of electric shock accidents about railway accidents during the last 5 years by analyzing the frequency of occurrence of human errors and unsafe acts, laws and regulations related to violations, and so on.

22,900[V] 전압에서 발생하는 감전사고를 살펴보기 위하여 최근의 감전사고에 대한 통계자료를 분석하였다. 22,900[V] 전압의 감전사고의 메커니즘을 실증하기 위해서 분석 결과에 근거하여 모의 감전사고 실험을 수행하였다. 실험에서는 여러 가지 상황에서 모의된 감전사고의 위험성을 정량적으로 분석하기 위하여 인체모형에 흐르는 전류를 측정하였다. 실험결과 감전 상황과 관계없이 일단 감전사고가 발생하면 인체에 치명적인 것으로 밝혀졌다.

The live line working is inherently dangerous as the workers have to work under the risk of electrical shock and most of works are carried out at height. The live line working need the some specific techniques and higher level safety measures such as a risk assessment to carry out works safely, but the electrical construction companies performed live-line working are usually small-sized companies. They have less capacity to have own safety management system. This study intended to conduct an in-depth analysis on the cause of electric shock accidents to provide basic data for policy proposing taking into considering the past eleven years for a long-term plan. And the aim of this study is to propose the policy about the equipment performance standards and/or worker's safety standards to revise the standards for preventing electric shock accidents, moreover, co-relation of the electrical work order form and on safety workings, especially electrical construction company/work.

As the statistical data, the electrical shock accidents by electrical power facilities of 22.9kV substation is about 100 per years which shows very high occupation rate of 11.3%. There is many hazard factors in this place using high voltage because electrical accident can be occurred in near live part as well as contact. Regarding electrical shock accident in 22.9kV substation as there are many cases that have not been exposed industrial disaster, it is very hard to know exact causes of such accidents in many cases, and therefore it is difficult to set up effective preventive measures. Therefore in this paper, it is intended to prepare the basic data to establish more effective preventive measures of electric shock accidents in 22.9kV substation through understanding the real conditions based on investigation and analysis in various types.

Electric shock due to the increased use of power, equipment accidents, electrical accidents, such as electric fire and also continues to grow. To prevent electric shock accidents, an experience education is more effective than indoctrination education. But an electric shock experience education system required a proper physical stimulation on human body to experience electric shock. In this study, we conducted a study to take advantage of the realistic haptic interface using a low-frequency type experiential learning and prevention education. Results of this study could be applied to an electric shock experience education system.
