What are the main causes of electrocution accidents

What are the main causes of electrocution? Below by the study la Xiaobian tell you the causes of electrocution accident! What are the main causes of electrocution accidents (1) lack of knowledge of electrical safety. For example, pulling the high voltage switch with electricity; touching the destroyed rubber cover knife gate with hands. (2) Violation of operating norms. For example, construction or transportation of large goods near high-voltage lines, construction tools or goods touching high-voltage lines; electrified contact lines and temporary power supply; fire wire mistakenly connected to the shell of power tools. (3) Poor maintenance. For example, the low voltage lines blown off by high winds are not repaired in time; the rubber cover switch is broken and not repaired for a long time. Line aging is not replaced in time. (4) Electrical equipment has potential safety hazards. For example, electrical equipment leakage; electrical equipment shell is not grounded, but charged; door gates and magnetic starters lack of shell protection; wires or cables are damaged due to insulation wear or corrosion. What are the precautions for using electrical equipment in the workplace? (1) Personnel who have not been trained and inspected for special operations and qualified for an induction certificate are not allowed to engage in electrical work. (2) Electrical equipment in the workshop shall not be operated dynamically at will. If the electrical equipment malfunctions, ask the electrician to repair it, and it shall not be repaired without authorization, nor shall it be operated with faults. (3) The electrician must check whether the electrical equipment is charged before operation. Any electrical equipment shall be regarded as charged until it is verified as non-charged, and shall not be touched blindly; closure is prohibited, otherwise operation is prohibited. (5) If it is necessary to move certain non-fixed installation of electrical equipment, such as lighting and relays, the power supply must be cut off first, and then moved to prevent the wires from being pulled off. (6) The operator often contact and use of the distribution box, distribution board, switches, push-button switches, sockets, plugs and wires must be kept safe and intact, shall not be damaged or exposed wires. (7) Thunderstorms should not be close to high-voltage poles, towers, lightning rods, etc., should be kept away from at least 20 meters away, to avoid cross-step voltage electrocution. (8) the occurrence of electrical fires, should immediately cut off the power supply, the use of yellow sand or carbon dioxide, carbon tetrachloride extinguishers to extinguish the fire,
