What are the hazards of electricity to the human body?

Electricity is indispensable in our life. People use electricity when they use electronic products. Electricity is indispensable in our lives. If there is no electricity, it will cause some inconvenience in life. If we use electricity correctly, it will not cause any harm to us. Then people will want to know under what circumstances electricity can cause harm to the human body. Next, let’s take a closer look at the hazards of electricity to the human body and the precautions we should take.

Electric shock refers to body damage, dysfunction, or even death caused by a certain amount and intensity of electric current or electricity (static electricity) passing through the human body. The harm of electric current to the human body can be summarized as the effects caused by the electric current itself and the thermal and light effects after being converted into electrical energy.

1. It is generally believed that voltages below 24V are safe, but voltages above 40V are dangerous. The fatal effect of electric current on humans is that it causes ventricular fibrillation and cardiac arrest, and it harms the respiratory center in the medulla oblongata, causing inhibition, paralysis and even respiratory arrest of the respiratory center. Low-voltage electric shock often causes ventricular fibrillation; high-voltage electric shock often causes cardiac arrest and respiratory arrest. There are three manifestations of cardiac arrest and respiratory arrest: (1) Cardiac arrest or ventricular fibrillation, but breathing is still present, which is more common in low-voltage electrical injuries below 1000V. (2) The heart is still beating, but there is no breathing. This is often seen in high voltage electrical injuries above 1000V. (3) Both heartbeat and breathing stop.

2. The hazards of electric current converted into heat and light effects are often seen in the damage caused by high voltage current to humans, mainly causing electric burns. In mild cases, only local skin and superficial muscles are burned, while in severe cases, deep muscles and even bones, spinal cord, etc. may be damaged.

The above is a detailed introduction to the hazards of electricity to the human body and the precautions. I believe that everyone has a better understanding of electricity usage in daily life. In our lives, it is recommended that you check the wiring, plugs, switches, etc. of your home electrical wires from time to time to see if there is any aging. If aging occurs, it should be replaced in time to avoid leakage and other problems.
