An Early Look at Operative Orthopaedic Injuries Associated with Electric Scooter Accidents: Bringing High-Energy Trauma to a Wider Audience.

There is a new method of transportation that started in our community in late 2017- rideshare electric scooters (e-scooters). These scooters have proven immensely popular and can now be found in many cities around the world. Despite the pervasiveness of e-scooters, their associated injury patterns are poorly understood. The purpose of this study was to describe our department's experience at the epicenter of the e-scooter phenomenon that is sweeping the globe and to characterize operative orthopaedic injuries that are related to e-scooter accidents. We performed a retrospective chart review of all of the operative orthopaedic cases and trauma consults at 2 trauma centers (a level-I center and a level-II center) between September 2017 and August 2019. We identified all operative injuries in which the cause of injury was an e-scooter accident. Data that included demographics, mechanism of injury, diagnosis, and treatment were collected. Seventy-five operative injuries were identified in 73 patients during the study period. The mean patient age was 35.4 years (range, 14 to 74 years), and the median age was 32 years. There were 4 pediatric patients (14, 15, 15, and 17 years old). Thirty-two patients (43.8%) sustained upper-extremity injuries, and 42 patients (57.5%) sustained lower-extremity injuries; 1 of these patients had both upper and lower-extremity injuries. Nine patients (12.3%) had open fractures. There were 7 hip fractures in patients with an average age of 42.4 years (range, 28 to 68 years). Seventy-one (97.3%) of 73 patients were e-scooter riders, and 2 (2.7%) were pedestrians who were struck by e-scooter riders. E-scooters can cause serious injury. Seventy-three patients required operative treatment in just the first 2 years of e-scooter use in our community. Operative injuries occurred throughout the skeletal system, and several were injuries that are typically associated with high-energy trauma. Although, as a rule, e-scooter use is limited to adults and banned in high pedestrian-traffic areas in our city, the inclusion of 4 underage riders and 2 pedestrians in our cohort suggests that these rules are not always followed. As e-scooters continue to increase in popularity, additional steps should be taken to regulate their use and protect riders and the public.

Implementation of Protective Device for Lineman Protection in Real Time Operation

this paper is proposed to control an electrical switch with the assistance of OTP based password. A keypad is associated with the task to enter the secret password. During the electric line fixing Lethal electrical accidents to the lineman are increasing because of the lack of communication between the linemen working staff and the electric substation officers. This proposed framework gives an answer, which can guarantee the wellbeing of the lineman. Since the control to turn on/off lies with the lineman. So there is the arrangement in the system and a password is required to operate the electrical switch i.e. on and off. The lineman has to carry the RF-ID tag that will be inserted into RF-ID reader to generate a one-time password. OTP will be received by the lineman. After inserting correct OTP Lineman will trip the supply and after securely repairing it, again he can turn the supply for respective phase. A microcontroller from ARDUINO family is used in the framework for complete operation and control. The microcontroller is interfaced with the matrix keypad to enter the secret one time password. The entered secret OTP is compared with the password stored in the microcontroller’s Read-only memory. If OTP matches with the stored one than only electrical switches can be turned on or off otherwise it will say the wrong password. A light emitting diode is used to intimate the activation and deactivation of the electrical switch. Because of the use of EEPROM, the user does not have to remember the secret password. The microcontroller is interfaced with the Global system of mobile (GSM) to monitor the operation by lineman by the means of SMS. When lineman trip the supply a message will be sent to a higher authority about the Activation and deactivation of the electrical switch.

Construction of Intelligent Electricity Platform under the Background of Intelligent Fire Protection

In order to forecast and warn the electric fire accidents, and to provide support for the emergency rescue of the electric fire accidents, the intelligent electric monitoring system is applied to the electric fire. The system uses Internet of Things, Mobile Internet, Cloud Platform and Big Data Technology to realize real-time online monitoring and graphical display of current, leakage, temperature, harmonic and other parameters of electrical lines. Once the electrical parameters exceed the threshold, they will alarm at the mobile terminal, monitoring screen, computer and other terminals. After the intelligent electric fire alarm system is issued, the basic information of enterprises, surrounding environment information and emergency information can be viewed through the system, so as to improve the speed and efficiency of emergency rescue. The system can realize the early warning of electric fire and provide support for emergency rescue of electric fire accidents.

Bicanalicular Lacerations: Clinical Characteristics and Surgical Outcomes With a New Bicanalicular Silicone Stent.

Bicanalicular lacerations are relatively rare and more of a surgical challenge in clinical practice. The purpose of this study is to evaluate the clinical characteristics and surgical outcomes of bicanalicular lacerations with a new bicanalicular silicone stent at a tertiary eye care center. All patients who underwent bicanalicular lacerations repair from January 2013 and December 2018 were retrospectively reviewed. Data collected for each patient included patient demographics, affected sides, cause of injuries, the timing of management, associated ocular injuries, the timing of stent removal, duration of follow-up and the outcomes of the surgical repair with a new bicanalicular silicone stent. Thirty-six patients with bicanalicular lacerations met the inclusion criteria and were enrolled in the study. The mean age of the patients was 43.8 years old (range: 2-73years). Of the 36 patients, 33 (91.7%) were males and 3 (8.3%) were females. The right eye was injured in 17 patients (47.2%). All patients underwent surgical intervention within 24 hours. The most common cause of bicanalicular lacerations was electric bicycles accidents (7 patients, 19.4%), and followed by motor vehicle accidents (6 patients, 16.7%), blunt objects (6 patients, 16.7%), fights (6 patients, 16.7%), falls (3 patients, 12%), dog bites (2 patients, 5.6%), hook injuries (2 patients, 5.6%), broken glass (2 patients, 5.6%), and sharp objects (2 patients, 5.6%). The most common associated ocular injuries were orbital fracture (61.1%), followed by lid lacerations and open globe injuries. The functional success rate was 86.1%. The average interval between the surgery and the stent removal was 13.8 weeks (range: 8-20 weeks). All the stents were removed successfully without any difficulty in the outpatient department. The follow-up after stent removal ranged from 2 to 12 months (mean: 5.1months). Bicanalicular lacerations involvement occured in 6.8% of all canalicular lacerations. The most common cause of bicanalicular lacerations was electric bicycles accidents and the most common associated ocular injuries was orbital fracture in North China. The new bicanalicular silicone stent achieved good functional success (86.1%) in the management of bicanalicular lacerations.

Assessment of the Extent of Electrical Safety Practices Among Staff and Students of Electrical Engineering Department of Bayero University, Kano, Nigeria

Researchers globally conducted several studies on electrical safety awareness and practices for improving occupational safety and health of workers. However, most of these studies were limited to industry workers, with few focusing on academic workshops/laboratories, and almost none in the case of Bayero University, Kano, Nigeria. This study therefore, aims to assess the extent of electrical safety practices among staff and students of electrical engineering department, Bayero University, Kano, Nigeria. The authors used descriptive research design in which 50-item structured questionnaire was used to collect data from 42 staff and 99 students of electrical engineering department, Bayero University, Kano, Nigeria. The results show that staff and students do not strictly observe electrical safety practices in the workshops/laboratories. The results also revealed the common causes of electrical accidents in the workshops/laboratories; nature of frequent electrical accidents; and measures to reduce electrical accidents and promote students’ compliance to electrical safety rules and regulations. The researchers limit this study to only department of electrical engineering in the faculty of engineering. Also, only quantitative data was collected from the respondents, without giving consideration to the in-depth information qualitative data (such as interview) would have provide. As such, conclusions derived using quantitative approach from the respondents relies on the genuineness of the information provided by them. The findings provide the faculty of engineering with a basis to introduce ‘Electrical Safety Awareness and Practices’ course into the curriculum.

Prediction and Analysis of Electrical Accidents and Risk Due to Climate Change.

The industrial development and the increase in the use of fossil fuels have been accelerating global warming and climate change, thereby causing more frequent and intense natural disasters than ever before. Since electrical facilities are generally installed outdoors, they are greatly affected by natural disasters, thus accidents related to electrical equipment has been on the rise. In this paper, we present the risk rating associated with climate change by analyzing the statistics of electrical fires, electric shock accidents and electrical equipment accidents caused by domestic climate change. Further, we present a risk rating analysis model for electrical fires on a monthly basis through the data analysis of electrical hazards associated with various regional (metropolitan city) climatic conditions (temperature, humidity), and analyze the accident risk rating for natural disasters related to low and high voltage equipment. Through this risk analysis model for each region and type of equipment, we presented a basic prediction model for electrical hazards. Therefore, it is possible to provide electrical safety services in the future by displaying a risk prediction map of electrical hazards for each region and type of electrical equipment through web sites or smart phone apps using the presented analysis data. Further, efforts should be made to increase the robustness or reliability of electrical equipment in order to prevent electrical accidents caused by natural disasters due to climate change in advance.

Elevation of Myostatin as a Potential Marker for Compartment Syndrome in Electrical Injuries

Electrical accidents and particularly subsequent compartment syndromes are challenging injuries for clinical treatment. Creatinine kinase (CK) and myoglobin are known lab parameters to detect a compartment syndrome. We followed up patients with electrical injuries between the years 2006 and 2016 at our burn unit. We aimed to analyse the role of myostatin as marker for compartment syndrome through serum measurements within 48 hours after injury. We collected data from 24 patients hospitalised with high-voltage electrical injury. All patients were male. We measured myostatin in 14 of these patients. While CK-MB (creatinine kinase muscle-brain type [MB]) showed no significant correlation to compartment syndrome, CK and myostatin gave highly significant increases. Interestingly, myostatin was significantly increased in electrical injuries but not burn injuries, while CK did not show a significant difference. Thus, besides CK, myostatin can serve as reliable early marker for compartment syndrome in electrical injuries.

THE APPLICATION OF RISK CALCULATION METHODS FOR ANALYSIS AND PREVENTION OF INDUSTRIAL INJURIES

The article was tasked with analyzing electrical injuries at metallurgical enterprises in Ukraine based on the construction of a „fault tree”. One of the reasons for choosing the lesion from the action of electric current is its high danger – the proportion of electrical accidents with a fatal outcome in the total workplace injuries reaches 40%.The fault tree is a graphical model of various parallel and sequential fault messages (events related to the failure of system elements, personnel errors, equipment unavailability), leading to the realization of a predetermined undesirable event, in this case – electric shock. Building a tree of failures allows you to calculate the probability of system failure, to find the most dangerous basic events and their combinations.A failure tree was compiled for the case of electric shock at a metallurgical plant. Minimal sections have been found, that is, rows of basic events that cause the onset of the upper (undesirable) event – electric shock. The probability of the minimum sections is calculated. Based on the significance indicators for Birnbaum and Fussell-Veseli, the basic events that make the greatest contribution to the risk of electric shock are determined. The first group of events concerns touching open conductive parts, the second – touching non-conducting parts that happened to be under voltage. Together, these two sections provide a 65% contribution to the overall risk. The defining basic events that make the greatest contribution to the risk are the erroneous voltage supply and the failure or absence of protection - grounding, zeroing, shutdown. These basic events are very dangerous – they are highly likely to lead to electric shock.To reduce the risk of electric shock, it is necessary to eliminate the erroneous voltage supply, or minimize this possibility. Ways of implementation – strengthening supervision over the implementation of work on current carrying parts, the observance of the system of work orders, for conducting briefings. As a technical measure, blocking of current switching devices is used during repair work. It can be recommended to use protective devices, which, depending on the network circuit and the specific situation, react to the potential of the case, earth fault current, zero-sequence current, operating current, and the like.

High Impedance Electrical Accidents: Importance of Source and Subject Impedance.

We used the following methodology for analyzing such cases: (1) Determine body pathway, (2) Estimate body pathway impedance, (3) Determine source voltage, (4) Determine source impedance, (5) Calculate delivered current using total pathway impedance, and (6) Ignore available current as it is largely confounding in most cases. We analyzed 6 difficult cases using the above methodology. This includes 2 subtle situations involving pairs of matched case-control subjects where a subject was electrocuted while his work partner was not. Careful calculations of the amplitude and duration of the shock is required for understanding the limits and potential causation of such electrical injury. This requires the determination of both the source and body pathway impedance. Available current is usually irrelevant and overemphasized.

The Case Study of Electrocution from the Use of a Charging Smartphone

스마트폰은 일상생활의 편리한 필수품이 되었으며 이러한 수요에 따라서 여러 가지 효율적인 전자기기의 발전과 개발제품에 대한 기대와 관심이 크다. 그럼에도 불구하고, 스마트폰의 안전사용에 관한 인식부족으로 감전에 노출될 가능성이 상존하고 있다. 감전(electric shock)이란 전기에너지가 인체를 통과하여 일어나는 신체의 장애현상으로 근육의 경미한 경련에서부터 감전사(electrocution)하는 경우에 이르기까지 다양하다. 가정용으로 사용되는 220 V의 저전압이라 하더라도 누전 상태에서 접촉할 경우에는 심실세동의 전류범위가 되어 감전될 수 있으며 사망에 이를 수 있다. 그러므로 언제든 주변에서 일어날 수 있는 감전사고의 원인과 이에 대한 위험성을 인식하고 감전사고에 대한 효과적이고 실질적인 예방대책을 모색해야 할 것이다. 본 사례에서는 국내에서 처음으로 발생한, 희소하게 발생한 사고를 바탕으로 감전사고의 메커니즘과 위험성에 대하여 보고한다.The mobile phones have become convenient necessities of everyday life. Following as this demand, various efficient electronic devices were developed and also increased the expectation and interest of the developed products. Nevertheless, there is a possibility of being exposed to electric shock due to lack of awareness about electrical safety of smart phone. An electrical injury is a physiological disorder caused by electric current passing through the human body, ranging from a slight cramping of the muscle to electrocution. Even at low voltage of 220 V used for home use, if contact on a short circuit stage, the current may become a range of the ventricular fibrillation that brings on the electric shock, which may lead to death. Therefore, it is necessary to recognize the danger of the electric shock accident and to find effective and practical solutions. The purpose of this study is to report on the risk of electric shock accident and the mechanism based on the first case reported in domestic.

Family Adherence on Children’s Preventive Measures on the Protection of Children

The aim of this study was to identify the impact of family adherence to preventive measures on protecting children aged 2 to 4 years from accidents inside and outside the home in the southern governorates of Jordan. The researcher was used descriptive approach design, as the sample of the study was 1200 mothers who have children aged 2-4 years in the southern governorates of Jordan (Karak, Tafilah, Ma'an and Aqaba). The study discussed the main accidents that a child may be exposed to including burning, suffocation, fall, poisoning, drowning, electrical, and other accidents such as road traffic accidents, glass-related accidents, sharp tools accidents, and strangulation including blind cords. The results revealed that most women were found to have poor knowledge regarding children accidents prevention. In addition, the result showed that there were a significant differences between the training course and the mother education on the protection of children aged 2 to 4 years from accidents in the southern governorates. Moreover, the results showed that the age of mother has an impact difference were the younger mothers were more follow the prevention measures in the protection of children. The resulte revealed that "Other Accidents (road traffic, glass-related, sharp tools and strangulation including blind cords)" was high scour between the seven accidents among the mothers on the southern governorates of Jordan. The researcher recommended that the importance of educating mothers about the need to adhere to preventive measures to protect children from accidents that may occur inside and outside the home.

Posterior fracture dislocation of the proximal humerus

Posterior dislocation fractures of the humerus occur as impression fractures of the humeral head (reverse Hill–Sachs fracture) and posteriorly dislocated proximal humeral (PH) fractures with a subcapital component. This study evaluated fracture patterns, current treatment, and revision rates. Data of patients who underwent surgical treatment for PH dislocation fractures in two level-I trauma centers between 2010 and 2018 were retrospectively reviewed. We identified 41 shoulders in 37 patients (n = 12 female, n = 25 male; average age 52 [25–91] years) with open surgical treatment of PH posterior dislocation fractures. In 14 patients, the cause was convulsive seizure or electrical accident, in 23 patients, a fall or high-energy trauma. There were 22 shoulders with impression fractures without a subcapital aspect; 19 shoulders had a posteriorly dislocated subcapital fracture. All patients were treated surgically via a deltopectoral approach. Five of the impression type fractures were treated prosthetically; the other 17 impression type fractures had humeral head-preserving reconstruction. The 19 cases of subcapital dislocation fractures were treated with open reduction and internal fixation with a PHILOS plate (n = 13) or with a prosthesis (n = 6). Within a mean follow-up period of 4.3 (1–9) years, the overall revision rate was 15% (6/41). Four patients underwent elective arthroscopic capsulotomy and implant removal. Two patients required revision surgery due to loss of reduction or humeral head necrosis. Impression type fractures were slightly more common than posteriorly dislocated PH fractures with a subcapital fracture component. In 73% of cases (n = 30), humeral head-preserving reconstruction was performed. The overall mid-term revision rate was 15% with a low-rate of secondary conversion to total shoulder arthroplasty (3%). Longer term functional outcomes of the patients are needed to better evaluate the treatment concept.

Put Your Lights On: Electrocution As a Cause of an Unexplained Fall and Loss of Consciousness.

Electrical accidents are not reported very frequently, and may occur undetected as the signs are often manifold and not very specific. We report the case of a 43-year-old woman admitted to hospital due to a fall of unclear cause, with loss of consciousness, partial amnesia, paresis of both legs and crush syndrome. Only by thorough and repeated history-taking, and a careful physical examination that revealed burns typical of electrical current injuries, was the case resolved. With this case presentation, we would like to make the reader aware of electrocution as a possible cause of bruises and unconsciousness of unclear origin.LEARNING POINTSBruises and loss of consciousness of unclear origin should make one think of electric shock as a possible cause.Rhabdomyolysis and crush syndrome are rarely seen conditions in low-voltage current accidents.Thorough physical examination and careful history-taking are very important and can provide precious hints for our clinical work.

Reliability Analysis of Electric Human Factors Based on Grey Correlation Analysis

On the basis of the analysis of power safety accidents by using the improved Human Factors Classification and Analysis System (HFACS) model, due to the large proportion of the cause of power safety accidents and the typical gray system characteristics, Grey correlation analysis was conducted for each factor of electric safety accident to determine the relationship between them. Using the results of gray correlation analysis of power safety accidents can provide theoretical support for the prevention of power safety accidents.

Comparison of the Incidence and Severity of Traumatic Brain Injury Caused by Electrical Bicycle and Bicycle Accidents—A Retrospective Cohort Study From a Swiss Level I Trauma Center

Electrical bicycles (E-bikes) allow people of all ages to ride at high speeds but have an inherent risk of traumatic brain injury (TBI). Their sales have increased tremendously in recent years. We performed a retrospective cohort study to compare the incidence and severity of TBI in E-bikers and conventional bicyclists. We included patients at a Swiss level 1 trauma center admitted from 2010 to 2015. The primary outcome was the association between TBI and the bicycle type. The secondary outcome was the association between helmet use and TBI severity. Of 557 patients injured riding an E-bike (n= 73) or a bicycle (n= 484), 60% sustained a TBI, most of which were mild (Glasgow coma scale [GCS] score, 13-15; E-bike, 78%; bicycle, 88%). TBI was more often moderate (GCS score, 9-12) or severe (GCS score, 3-8) in E-bikers than in bicyclists (P= 0.04). Intracranial hemorrhage, traumatic subarachnoid hemorrhage, and subdural hematoma occurred significantly more often in E-bikers than in bicyclists (P < 0.05). Neurosurgical intervention was necessary for 5 E-bikers (7%) and 25 (5%) bicyclists (P= 0.15). Wearing a helmet correlated with a lower risk of neurosurgical intervention in bicyclists (odds ratio [OR], 0.21; 95% confidence interval [CI], 0.06-0.73; P= 0.01) and a lower risk of calvarial fractures in both bicyclists (OR, 0.16; 95% CI, 0.06-0.42; P < 0.01) and E-bikers (OR, 0.21; 95% CI, 0.05-0.84; P= 0.03). E-bikers had a significantly greater risk of moderate to severe TBI compared with bicyclists. Helmet use was associated with decreased odds of severe TBI in bicyclists and a tendency toward a more favorable outcome for E-bikers.

Electrical Safety in Developing Countries [Electrical Safety

Electrical safety efforts by utilities, government, and industry have resulted in significant reductions in the number of electrical injuries and fatalities in North America, Europe, and other developed areas. However, electrical accidents in developing countries continue to maim and kill people at an alarming rate. Unfortunately, accurate statistics for electrical injuries are lacking in most developing nations. Recent estimates by IEEE Industry Applications Society (IAS) Senior Member Satish Chaparala (Hyderabad, India) have shown that approximately 22 people per day are electrocuted in India. Further research has suggested that similar large numbers of electrical injuries and fatalities are occurring in developing countries in Africa, South America, and Asia.

Investigation on present labour accidents due to electric shock and comparison of safety devices for preventing electric shock accidents used for arc welding equipment in foreign countries

休業4日以上の感電に起因する労働災害を厚生労働省の労働災害（死亡・休業4日以上）データベースを用いて平成18～27年の10年間を分析した結果，定性的な状況は平成10年以前と感電災害の多く発生している業種，発生月，感電災害を誘引した起因物などに変化の無いことを明らかにした．

Perceived Electrical Injury: Misleading Symptomology Due to Multisensory Stimuli.

An electrical accident victim's recollection is often distorted by Bayesian inference in multisensory integration. For example, hearing the sound and seeing the bright flash of an electrical arc can create the false impression that someone had experienced an electrical shock. These subjects will often present to an emergency department seeking either treatment or reassurance. We present seven cases in which the subjects were startled by an electrical shock (real or perceived) and injury was reported. Calculations of the current and path were used to allocate causality between the shock and a history of chronic disease or previous trauma. In all seven cases, our analysis suggests that no current was passed through the body. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Symptomology seen as corroborating may actually be confounding. Witness and survivor descriptions of electrical shocks are fraught with subjectivity and misunderstanding. Available current is usually irrelevant and overemphasized, such as stress on a 100-ampere welding source, which is orders of magnitude beyond lethal limits. History can also be biased for a number of reasons. Bayesian inference in multisensory perception can lead to a subject sincerely believing they had experienced an electrical shock. Determination of the current pathway and calculations of the amplitude and duration of the shock can be critical for understanding the limits and potential causation of electrical injury.

Risk of cardiac arrhythmias after electrical accident: a single-center study of 480 patients

ObjectivePatients with electrical injury are considered to be at high risk of cardiac arrhythmias. Due to the small number of studies, there is no widely accepted guideline regarding the risk assessment and management of arrhythmic complications after electrical accident (EA). Our retrospective observational study was designed to determine the prevalence of ECG abnormalities and cardiac arrhythmias after EA, to evaluate the predictive value of cardiac biomarkers for this condition and to assess in-hospital and 30-day mortality.MethodsConsecutive patients presenting after EA at the emergency department of our institution between 2011 and 2016 were involved in the current analysis. ECG abnormalities and arrhythmias were analyzed at admission and during ECG monitoring. Levels of cardiac troponin I, CK and CK-MB were also collected. In-hospital and 30-day mortality data were obtained from hospital records and from the national insurance database.ResultsOf the 480 patients included, 184 (38.3%) had suffered a workplace accident. The majority of patients (96.2%) had incurred a low-voltage injury (< 1000 V). One hundred and four (21.7%) patients had a transthoracic electrical injury while 13 (2.7%) patients reported loss of consciousness. The most frequent ECG disorders at admission were sinus bradycardia (< 60 bpm, n = 50, 10.4%) and sinus tachycardia (> 100 bpm, n = 21, 4.4%). Other detected arrhythmias were as follows: newly diagnosed atrial fibrillation (n = 1); frequent multifocal atrial premature complexes (n = 1); sinus arrest with atrial escape rhythm (n = 2); ventricular fibrillation terminated out of hospital (n = 1); ventricular bigeminy (n = 1); and repetitive nonsustained ventricular tachycardia (n = 1). ECG monitoring was performed in 182 (37.9%) patients for 12.7 ± 7.1 h at the ED. Except for one case with regular supraventricular tachycardia terminated via vagal maneuver and one other case with paroxysmal atrial fibrillation, no clinically relevant arrhythmias were detected during the ECG monitoring. Cardiac troponin I was measured in 354 (73.8%) cases at 4.6 ± 4.3 h after the EA and was significantly elevated only in one resuscitated patient. CK elevation was frequent, but CK-MB was under 5% in all patients. Both in-hospital and 30-day mortality were 0%.ConclusionsMost of cardiac arrhythmias in patients presenting after EA can be diagnosed by an ECG on admission, thus routine ECG monitoring appears to be unnecessary. In our patient cohort cardiac troponin I and CK-MB were not useful in risk assessment after EA. Late-onset malignant arrhythmias were not observed.

A study on the development of an autonomous electrical safety management service using an IoT-based smart outlet

At present, individual households within a multi-family residential are at susceptible to electrical accidents. As if in a blind spot, they cannot be covered under electrical safety management. This paper presents issues about an autonomous electrical safety management service which uses smart outlets to ensure electrical safety for individual households. Risk factors surrounding electrical incidents occurring in a mashup tech-based environment were analyzed and a smart outlet equipped with a prediction technique was developed. In addition to this, an autonomous electrical safety management service scenario was developed to handle mechanical failures in autonomous electrical safety devices which run on IoT-based smart outlets. By utilizing such an autonomous electrical safety management service model, technology for electrical safety security was developed for individual households or each residential unit in multi-dwelling unit. The correlation among voltage, current, and zero phase current was analyzed to identify the risk factors of electrical accidents and to predict accidents. In order to detect arc faults, a new prediction technique was developed. The technique is based on the mashup technology after analyzing waveform and FFT derived from the correlation among voltage, current, and zero phase current. In particular, the techniques applied to analyze nonlinear models such as an arc fault show the diversity in the application areas of traditional fast fourier transform (FFT) algorithms. Furthermore, by using such a technique for electrical accident prediction, an autonomous electrical safety management model was developed. Thus, a measure to ensure micro-grid electrical safety was presented. There is the hope that this development of the management technique for individual households in connection with the fourth industrial revolution would contribute to electrical safety.
