Electric shock refers to the experience of an electric current travelling through the body. Our bodies conduct electricity, so when we come into contact with a live electrical current, it passes through our body and causes an electric shock. The severity of an electric shock depends on several factors, including the voltage, the type of current, the duration of contact, and the pathway the electricity takes through the body. Electric shocks can cause a variety of symptoms, ranging from mild to severe, and can sometimes be fatal. It is important to seek medical attention after an electric shock, even if there are no noticeable symptoms, as internal injuries may not be obvious.

Electric shocks occur when the body comes into contact with electricity
The most common injury caused by an electric shock is burns. If the shock is prolonged or the current is high, tissue can be burned. The points of contact with the electrical source and the ground are usually the most severely burned. Common points of contact include the hands, heels, and head. In some cases, there may be very little external evidence of injury, while in other cases, the individual may be in cardiac arrest or experience internal injuries.
Electric shocks can also lead to falls, as the electricity stimulates muscles and can cause muscle contractions or a startle reaction. A person may fall from a ladder, scaffold, or aerial bucket, and these falls can result in serious injuries. Additionally, the ultraviolet (UV) and infrared (IR) light emitted by an electric arc flash can cause eye damage, and a potential pressure wave released by an arc flash can cause physical harm, including collapsed lungs or hearing damage.
To prevent electric shocks, it is important to avoid situations where one might come into contact with electricity. This includes staying away from fallen power lines, using safe electrical appliances, and having a qualified electrician check second-hand appliances. If you arrive at the scene of an accident involving fallen power lines, it is important to maintain a distance of at least 8-10 meters until it is declared safe by authorities.

Shocks can cause a range of effects, from a tickle to severe burns, cardiac arrest, or death
An electric shock occurs when a person comes into direct contact with an electrical energy source, causing electrical energy to flow through a portion of their body. The human body is a good conductor of electricity, which means that electric current can easily travel through it.
The effects of an electric shock can range from mild to severe, with the most common injury being burns. Shocks from light switches or household appliances are usually less severe, whereas shocks from industrial power sources can cause more severe effects. The severity of the shock also depends on the voltage and the duration of contact. For example, currents less than 5mA are not considered dangerous, whereas currents above 10mA can cause sustained muscle contractions, violent spasms, and loss of muscular control. In addition, a current of 50mA passing through the heart can cause cardiac arrest and even death.
Other potential effects of electric shock include compartment syndrome, which occurs when muscle damage causes the limbs to swell and compress arteries. This can lead to serious health problems that may not be immediately noticeable. Nerve damage can also occur, resulting in pain, tingling, numbness, weakness, or difficulty moving a limb. These effects may be temporary or permanent, and there is also a risk of long-term damage to the central nervous system and brain, which can manifest as psychiatric disorders.
It is important to note that the immediate response to an electric shock can significantly impact minimizing its effects. If someone is experiencing a high-voltage shock, it is crucial to call emergency services. Even in the case of a low-voltage shock, it is recommended to seek medical advice to ensure there is no internal damage, as it can be hard to detect without a thorough medical exam.

Burns can be caused by electric arcs, flame burns, or contact burns
An electric shock occurs when a person comes into direct contact with an electrical energy source, allowing electrical energy to flow through a portion of their body. This exposure to electrical energy can cause no harm at all, or it can lead to severe damage or even death. The most common injury caused by an electric shock is burns.
Contact burns occur when a person touches electrical wiring or equipment that is used or maintained improperly. The severity of the burn depends on the voltage of the electricity, the amount of body contact, and the duration of contact. High-voltage burns occur when a patient makes direct contact with a high-voltage electrical source, causing severe damage throughout the body. Low-voltage burns are caused by contact with a power source of 500 volts or less and may be mild, superficial, or severe depending on the contact time.
In addition to the visible skin damage, electrical burns can cause severe internal injuries. The current typically follows the path of least resistant tissues, including blood vessels, nerves, muscles, skin, tendons, fat, and bone. As a result, electrical burns can cause damage to internal tissues and organs, such as the heart, veins, and arteries. The extent of internal damage may be underestimated, as only the entry and exit wounds are visible, and complications can arise if the injured tissue is not treated promptly.

Electric shocks can cause internal injuries, especially if the person experiences chest or abdominal pain
An electric shock occurs when a person comes into direct contact with an electrical energy source, resulting in an electric current flowing through their body. The severity of injuries caused by electric shocks ranges from mild to severe and, in some cases, even fatal. Electric shocks can cause four major types of injuries: electrocution, electric shock, burns, and falls.
Burns are the most common injury caused by electric shocks. The heat emitted by an electric arc flash can cause thermal burns, while the ultraviolet (UV) and infrared (IR) light emitted by the arc flash can lead to eye damage. However, burns are not always externally visible, and internal tissues can be affected without any signs of injury on the skin's surface.
The severity of electric shock injuries depends on several factors, including the type of current (AC or DC), the amount of current, and the pathway the electricity takes through the body. High-voltage shocks are more likely to cause serious symptoms, including deep burns, compared to low-voltage shocks, which may result in only superficial burns or muscle spasms. However, it is important to note that even low-voltage shocks can potentially lead to more severe injuries.

Safety precautions, such as safety switches and avoiding dangerous situations, can help prevent electric shocks
Electric shocks can cause severe injuries and even be fatal in some cases. Safety precautions are essential to prevent such incidents, and safety switches play a crucial role in this regard.
Safety switches, also known as residual current devices (RCDs) or ground fault circuit interrupters (GFCIs), are electrical safety devices designed to protect against electric shocks. Unlike circuit breakers that safeguard electrical circuits, safety switches are intended to protect people and property. They achieve this by detecting and responding to electrical leakage currents, which can occur when there is an imbalance in the current flow. If the difference between incoming and outgoing current exceeds a safe threshold, the safety switch trips, instantly disconnecting the power supply to the affected circuit. This rapid response, often within milliseconds, is a reliable way to prevent electric shocks, electrocution, and potential electrical fires.
In addition to safety switches, there are several other safety precautions to prevent electric shocks:
- Regularly check power cords, plugs, and outlets for any signs of damage, such as fraying, exposed wires, or loose connections.
- Avoid water and moisture when dealing with electrical equipment. Do not touch electrical appliances with wet hands or when standing in water.
- Unplug devices slowly and cautiously by gripping the plug's head, not the cord.
- Use appropriate personal protective equipment (PPE) like insulated gloves, safety glasses, and flame-resistant clothing when working with electricity.
- Keep electrical appliances away from children. Use tamper-resistant receptacles to protect young children from shocks.
- Avoid overloading outlets by plugging in too many cords.
By following these safety measures and staying vigilant, the risk of electric shocks can be significantly reduced.

Frequently asked questions
An electric shock is when electricity runs through your body. It occurs when a person comes into contact with an electrical energy source.
Contact with energised wiring or devices is the most common cause of an electric shock. In cases of exposure to high voltages, direct contact may not be necessary as the voltage may "jump" the air gap to the electrical device.
An electric shock can cause a tickle, muscular spasms, serious burns, cardiac arrest, and even death. In children, a typical electrical mouth burn from biting an electric cord appears as a burn on the lip with a red or dark, charred appearance.
If you are with someone who is experiencing an electric shock, do not touch them if they are still in contact with an electrical current. If it is safe to do so, disconnect the power supply and call for emergency medical services.
