Can static electricity electrocute people?

Static electricity is formed when an object or surface accumulates charges, which are divided into positive and negative charges, that is, electrostatic phenomena are also divided into positive and negative charges.

Positive charges gather on objects to form positive static electricity, while negative charges gather on objects to form negative static electricity. However, whether it is positive or negative static electricity, when an electrostatic object touches an object with zero potential (grounded object) or an object with potential difference, charge transfer will occur, which is the phenomenon of spark discharge we see every day.

For example, when the weather is dry in winter in the north, the human body is prone to static electricity, and it will discharge when it comes into contact with others or metal conductors. People will feel tingling from electric shock, and sparks can be seen at night, which is why chemical fiber clothing rubs against human body and brings positive static electricity to human body.

Extended data:

There are many hazards of static electricity, first of all, it comes from the interaction of charged bodies. When the aircraft body rubs against air, water vapor, dust and other particles, it will make the aircraft charged, and if no measures are taken, it will seriously interfere with the normal work of the aircraft radio equipment; In a printing factory, the static electricity between pages will make the pages stick together, making it difficult to separate them, which will bring trouble to printing;

In the pharmaceutical factory, because static electricity attracts dust, the medicine can't reach the standard purity; When the TV is turned on, the static electricity on the screen is easy to absorb dust and oil, forming a dust film, which reduces the clarity and brightness of the image; The common dust that is difficult to pat off on blended clothes is also a ghost of electrostatic rammer.

The second biggest hazard of static electricity is that it may explode because some flammable objects are ignited by electrostatic sparks. In the dark night, when people take off their nylon and woolen clothes, they will emit sparks and beep, which is basically harmless to the human body. But on the operating table, electric spark will cause the explosion of anesthetic, hurting doctors and patients; In coal mines, gas explosion will be caused, resulting in the death and injury of workers, and the mine will be scrapped. In a word, electrostatic hazards are caused by electricity and electrostatic discharge, and the most serious electrostatic discharge will cause fires and explosions of combustible substances.
