Electrical shock

(1) Electric shock accident. When a person touches a live body (or is too close to a high-voltage live body), personal injury accidents caused by the current flowing through the human body. Electric shock accidents are caused by the application of electric current energy to the human body. Electric shock can be divided into three types: single-phase electric shock, two-phase electric shock and step-voltage electric shock.

(2) Lightning and electrostatic accidents. The positive and negative charges that are temporarily out of balance in the local area release the energy of the charge under certain conditions, causing harm to the human body or other accidents. Lightning strikes can often destroy buildings, injure people and animals, and may also cause fires; The biggest threat of electrostatic discharge is to cause fire or explosion accidents, and it can also cause harm to the human body.

(3) RF damage. The damage caused by the energy of the electromagnetic field to the human body is also known as electromagnetic field damage. Under the action of high-frequency electromagnetic fields, the human body will suffer varying degrees of damage to various organs due to the absorption of radiation energy, thus causing various diseases. In addition to high-frequency electromagnetic fields, ultra-high-voltage high-intensity power frequency electromagnetic fields can also cause certain harm to the human body.

(4) Circuit failure. Accidents caused by loss of control in the process of transmission, distribution and conversion of electrical energy. Faulty lines and equipment not only threaten personal safety, but also seriously damage electrical equipment.

The above four types of electrical accidents are the most common electric shock accidents. But no matter what kind of accident it is, it is caused by the improper release or transfer of energy from various types of currents, charges, electromagnetic fields.
