现代生活水平的提高,电视机、电风扇、电冰箱、洗衣机、空调等家用电器已逐步在百姓家中普及,作为二次能源的电,已成为人们生活中必不可少的物质。冬季,电热毯、热水器的使用率上升。但由于人们缺乏对电性能及安全用电知识的了解,加上一部分家庭使用家电不当或使用劣质产品,使触电事故不断上升,如处理不及时,常危及到使用人的生命。当电老虎“咬人”时,该怎么办?一般我们称民用电为220V左右,属低压电范围,但电流值一般较大,易造成触电人的全身性损害,特别是心脏。一旦发生触电,
With the improvement of modern living standards, household appliances such as televisions, electric fans, refrigerators, washing machines and air conditioners have been gradually popularized in people’s homes, and electricity as secondary energy has become an indispensable substance in people’s lives. In winter, the usage of electric blankets and water heaters has increased. However, due to lack of knowledge about electrical properties and safety of electricity use, and some household improper use of household electrical appliances or use of inferior products, the number of accidents involving electric shocks is constantly on the rise. If the handling is not handled in time, the life of the user is often endangered. When the electric tiger “bites”, what to do? Generally we call the civilian electricity is about 220V, is a low-voltage range, but the current value is generally larger, easy to cause the whole body electric shock damage, especially the heart. In the event of an electric shock,
