Patterns of electric shock accidents

Thread Content

Electric shock accidents often occur suddenly and cause extremely serious consequences in a very short period of time. However, it should not be thought that electric shock accidents are impossible to prevent. To prevent electric shock accidents, it is necessary to study the patterns of such accidents in order to develop effective safety measures. Based on the analysis of electric shock accidents, regarding their frequency of occurrence, the following patterns can be identified: (1) Electric shock accidents are highly seasonal. Domestic and international statistical data show that accidents are more frequent in the second and third quarters of each year, with the highest incidence between June and September. This is mainly because the weather is hot during this period, people wear many layers of clothing and sweat a lot, increasing the risk of electric shock ； It is also due to the rainy and humid weather during this period, as well as the reduced insulation performance of electrical equipment. (2) There are many electric shock accidents involving low-voltage equipment. Statistical data from both domestic and international sources show that low-voltage electric shock accidents are far more common than high-voltage electric shock accidents. This is mainly because there are far more low-voltage devices than high-voltage devices, and the people who come into contact with them lack knowledge of electrical safety. (3) There are many electric shock accidents involving portable and mobile devices. This is mainly because these devices need to be moved frequently, operate in poor conditions, are prone to failure, and often have to function under heavy pressure. (4) Electric shock accidents are common at electrical connection points. Electrical accidents often occur at branch lines, service lines, ground wires, connection terminals, compression terminals, welded joints, wire connectors, cable ends, light fixtures, plugs, sockets, controllers, switches, contactors, fuses, and other such components. This is mainly because the mechanical strength of these connection points is poor, their electrical reliability is low, and they are prone to failure. (5) There are many electric shock accidents in rural areas. According to statistical data from some provinces and cities in our country, electric shock accidents in rural areas are six times higher than those in urban areas. This is mainly due to poor electricity supply conditions in rural areas, rudimentary equipment, low technical skills among the staff, inadequate management, and a lack of knowledge regarding electrical safety. (6) Electric shock accidents are common in the metallurgy, mining, construction, and machinery industries. Due to adverse factors such as humidity, high temperatures, complex working conditions, a large number of mobile and portable devices, as well as numerous metal equipment on site, electric shock accidents are common in these industries. (7) Accidents are more common among young and middle-aged people as well as non-electricians. This is mainly because these people are mostly operators, that is, those who work with electrical equipment. Also, it is due to a lack of experience and insufficient knowledge of electrical safety. (8) There are many accidents caused by misoperations. It is mainly due to insufficient education and inadequate safety measures.
