The benefits of electricity
There is no difference between people on the great importance of electricity in this era, as it is the main engine in all areas of life, starting from the home with its main electrical appliances in the kitchen, television, lighting, and various heating factors, passing through the various medical equipment inside Hospitals, computer systems, radiography, and other devices that are important in data processing to provide correct readings quickly and with high accuracy for diagnosing diseases, providing the most appropriate treatment for various cases, and ending with their effective role in schools, airports, trains, and even cars and mobile devices of all kinds.

As a result of man’s dependence on electricity in his life, its nature has changed and developed relatively quickly, so people’s requirements differ according to the pace at which the tremendous developments of technology and artificial intelligence are escalating, and the extent of their impact on the individual and the group on the personal and practical levels. Electricity has transformed from a mere scientific curiosity that was discovered a century and a half ago. Almost to one of the luxuries of the wealthy, until now it has become a basic modern need for different people and ages.

Electricity hazards
The severity of the risks of electricity varies according to the strength and type of electric current, how it moves through the body of the injured person, the duration of exposure to it, in addition to the speed of receiving treatment, and the personal health and safety of the injured person before exposure to the current, as electric charges when they pass through the human body cause many different injuries, as they may be The injuries are external, that is, they are limited to skin burns only, or they may be internal, including: damage to the nerves, organs, bones, and muscles, and their effect may reach the heart, causing changes in the rhythm of its beating or stopping it in severe cases.

The danger of electricity is concentrated on humans because of its conductive nature; Because his body consists of 70% of water, and water is a good conductor of heat and electricity.

The types of electrical injuries are summarized as follows:
electric shocks
Electrical burns.
Loss of the ability to control the muscles, and this occurs when the body is electrocuted, so that he becomes unable to escape from it, and then he feels muscle spasms, which are capable of breaking the bones of the injured person, or dislocating his joints, or pushing his body randomly with great force that exposes him to danger if he works on high altitude, or close to other machines nearby.

Thermal burns.
Irregular heart rate or damage due to exposure to electrical waves.
Tissue damage caused by electric current flowing through it.
The occurrence of a physical disturbance in the cells or their membranes, as cells that are exposed to a voltage of more than 0.5 volts for more than 1 millisecond lead to the formation of defects in the cell membrane structure that do not close automatically, especially if they are large enough.
Deep internal and external burns on the victim's body.
Causing an imbalance in the body and its fall.
