What are the factors causing electric shock accidents?

The factors causing electric shock accidents are: the human body is in direct contact with the power supply and the current is derived from the human body, forming a loop.

Electric shock refers to the process of causing injury when electric current enters and passes through the human body. Two conditions must be met at the same time to cause electric shock. The human body is in direct contact with the power source and the current is derived from the human body, forming a circuit. These two conditions are indispensable.

Common causes of electric shock accidents:

Lack of electrical safety knowledge, such as pulling a high-voltage isolating switch when live; children playing with live wires, etc. Violations of operating procedures include maintenance of low-voltage lines or broadcast lines on line poles erected with high- and low-voltage power poles, and the voltage used by portable lights does not meet the safety voltage, etc.

Unqualified electrical equipment, such as electric shock due to lack of protective shell of knife switch or magnetic starter, electrical equipment shell not being grounded and being electrified, disassembly and assembly of cables while electrified, etc. Poor maintenance such as low-voltage lines that were blown down by strong winds and failed to be repaired in time.

Accidental factors such as wires broken by strong winds falling on the human body. From the above analysis of the causes of electric shock, it can be seen that except for accidental factors, everything else can be avoided.

Measures to prevent electric shock:

1. Purchase qualified electrical appliances: There are many electric shocks caused by electrical leakage, so you should purchase qualified electrical products.

2. It is forbidden to pull the wires without permission: Many people will use the socket to pull the wires for convenience. This is very dangerous and can easily be kicked or stepped on, and accidents can easily occur if you are not careful. If the socket is exposed to water or the wire leaks, electric shock accidents may easily occur.

3. Disconnect the power supply and then check the electrical appliances: No matter when using wires, disconnect the power supply first.

4. Do not touch sockets and switches with wet hands: It is very dangerous to touch various electrical switches with wet hands. Water entering the gaps of switches and sockets can easily cause electric shock.

5. Repair circuit faults in a timely manner: It is inevitable to encounter circuit faults in life. At this time, do not repair it by yourself, seek help from professionals, and use professional measures to repair, otherwise it will easily be caused by improper operation. And get electrocuted.
