If you don't save yourself in time within 3 to 4 minutes after being shocked by 220v, you will die. If you touch 220 V, you won't die immediately. Contact will cause cardiac arrest and induce respiratory arrest. After 65,438+0 minutes, your brain will be irreversibly damaged. After a long time, your brain will die. Therefore, it is essential to get out of the electric shock environment in time and rescue you urgently.

The voltage that is safe for human body is generally not higher than 36V, and 220V electric shock is a common name for electric injury, which usually refers to tissue damage and dysfunction caused by direct contact with power supply or high-voltage electricity passing through air or other conductive media. In severe cases, heartbeat and respiratory arrest will occur, and high-voltage electricity exceeding 1000V (volts) will also cause burns. Lightning damage (lightning strike) belongs to the category of high voltage electrical damage.

Extended data

If anyone is found to get an electric shock, they should first call the police and call the power supply service hotline 95598 to inform the operator of the detailed accident location, so that the power supply enterprise can determine the fault point in the shortest time, cut off the power supply and prevent more casualties.

If conditions permit, self-help can be implemented first. If you feel numb or other signs of electric shock in the water, you can jump out of the stagnant water area with one foot. Remember, when jumping with one foot, one foot can't touch the ground or water.

If you want to help others, the rescuer must stand on the dry ground, hold a dry wooden stick, bamboo pole or dry cloth and other non-conductive objects to open the live wire, or move the wounded away with non-conductive objects and get rid of the power supply as soon as possible.
