Electric shock can cause accidents in any environment where electrical cables or appliances are located. Generally these accidents occur in the home or work environment and most are produced by mishandling of the machines in question, or by negligence in the handling of electrical appliances or equipment.

- Handling or handling of faulty electrical appliances.
- Handling or repairing electrical outlets without having the necessary knowledge for this.
- Having contact with broken or unprotected cables that are within the reach of people.
- High-voltage lines can release sparks, so it is not necessary to have direct contact and without touching them, they produce sparks that cause a discharge, which can cause an electric arc and therefore an electrification.
- The Lightning.
- The machinery at work due to uncontrolled handling.
- In the case of children, they can insert objects into electrical outlets, break or chew on cables.
Discharge flow

Usually it identified with the flow volume, or volume passing through a specific area in a unit of time.
Electrostatic discharge is also caused by the attraction between two opposite bodies, one positive and the other negative, in addition to other factors, such as the release of electrons, which in turn causes an increase in triboelectricity (static electricity) and this it subsequently causes the sudden electrostatic discharge.
