How to check electrician certificate online in Hengli, Dongguan 2016, electrician training institution

Electrical safety includes personal safety and equipment safety. If a personal accident occurs, it may range from burns to death. If an equipment accident occurs, the equipment will be damaged and may cause fire or explosion. Therefore, we must attach great importance to safe use of electricity and have basic knowledge of safe use of electricity. Human body electric shock means that when a person, as a conductive body, touches a charged body with a potential difference, the current flows through the human body and causes injury. Electric shock refers to the damage caused by electric current passing through the human body to cells, nerves, bones and organs. This kind of injury usually manifests as a pinprick sensation, a sense of pressure, a sense of blow, muscle twitching, nerve paralysis, etc. In severe cases, it can cause coma, suffocation, or even death due to cardiac arrest. Electric shock injuries mainly occur inside the human body.

The current consensus on the main cause of death caused by electric shock is that current flowing through the human body causes ventricular fibers to Trembling causes heart dysfunction, interrupts blood supply, and causes respiratory suffocation, leading to death. <> .Electric Injuries Electric injuries are injuries caused to the human body by the thermal, chemical, and mechanical effects of electric current, such as electric burns, arc burns, electric branding, skin metallization, mechanical damage, electro-optical eyes, etc. Electrical injuries generally occur when the current is large and the voltage is high. Electrical injuries are local injuries and generally leave obvious scars on the surface of the body. Approximately % of electric shock injuries are purely electrical or charged.
