Electrical shock

Lightning injury caused by a nearby lightning strike. The slight branching redness (sometimes called a Lichtenberg figure) travelling up the leg was caused by the effects of current.

Electrical injury is a physiological reaction caused by electric current passing through the body.[2] The injury depends on the density of the current, tissue resistance and duration of contact.[3] Very small currents may be imperceptible or produce a light tingling sensation. A shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. Stronger currents may cause some degree of discomfort or pain, while more intense currents may induce involuntary muscle contractions, preventing the person from breaking free of the source of electricity.[4] Still larger currents result in tissue damage and may trigger ventricular fibrillation or cardiac arrest. Consequences of injury from electricity may include amputations, bone fractures and orthopedic and musculoskeletal injuries.[5] If death results from an electric shock the cause of death is generally referred to as electrocution.

Electric injury occurs upon contact of a body part with electricity that causes a sufficient current to pass through the person's tissue. Contact with energized wiring or devices is the most common cause. In cases of exposure to high voltages, such as on a power transmission tower, direct contact may not be necessary as the voltage may "jump" the air gap to the electrical device.

Following an electrical injury from household current, if a person has no symptoms, no underlying heart problems, and is not pregnant further testing is not required.[6] Otherwise an electrocardiogram, blood work to check the heart, and urine testing for signs of muscle breakdown may be performed.[6]

Management may involve resuscitation, pain medications, wound management, and heart rhythm monitoring.[6] Electrical injuries affect more than 30,000 people a year in the United States and result in about 1,000 deaths.[1]

Signs and symptoms[edit]Burns[edit]

Second-degree burn after a high tension line accident

Heating due to resistance can cause extensive and deep burns. When applied to the hand, electricity can cause involuntary muscle contraction, producing the "no-let-go" phenomenon, and increasing the risk for serious burns.[7] Voltage levels of 500 to 1000 volts tend to cause internal burns due to the large energy (which is proportional to the duration multiplied by the square of the voltage divided by resistance) available from the source. Damage due to current is through tissue heating and/or electroporation injury. For most cases of high-energy electrical trauma, the Joule heating in the deeper tissues along the extremity will reach damaging temperatures in a few seconds.[8]

Ventricular fibrillation[edit]

A domestic power supply voltage (110 or 230 V), 50 or 60 Hz alternating current (AC) through the chest for a fraction of a second may induce ventricular fibrillation at currents as low as 30 milliamperes (mA).[9][10][11] With direct current (DC), 300 to 500 mA is required.[12] If the current has a direct pathway to the heart (e.g., via a cardiac catheter or other kind of electrode), a much lower current of less than 1 mA (AC or DC) can cause fibrillation. If not immediately treated by defibrillation, ventricular fibrillation is usually lethal, causing cardiac arrest, because all of the heart muscle fibres move independently instead of in the coordinated action needed for successful cardiac cycle to pump blood and maintain circulation. Above 200 mA, tetanic muscle contractions are so strong that the heart muscles cannot move at all, but these conditions prevent fibrillation.[11]

Mechanism[edit]

Mechanism of cardiac arrhythmias induced by electricity is not fully understood, but various biopsies have shown arrhythmogenic foci in patchy myocardial fibrosis which contained increased amount of Na+ and K+ pumps, possibly associated with transient and localized changes in sodium-potassium transport as well as their concentrations, resulting in changes in membrane potential.[10][13]

Neurological effects[edit]

Electrical current can cause interference with nervous control, especially over the heart and lungs.[citation needed] Electric shock which does not lead to death has been shown to cause neuropathy at the site where the current entered the body.[7] The neurologic symptoms of electrical injury may occur immediately, which traditionally have a higher likelihood for healing, though they may also be delayed by days to years.[7] The delayed neurologic consequences of electrical injury have a worse prognosis.[7]

When the path of electrical current proceeds through the head, it appears that, with sufficient current applied, loss of consciousness almost always occurs swiftly. This is borne out by some limited self-experimentation by early designers of the electric chair[citation needed] and by research from the field of animal husbandry, where electric stunning has been extensively studied.[14]

If ventricular fibrillation occurs (as above), the blood supply to the brain is diminished, which may cause cerebral hypoxia (and its associated neurologic consequences).

Mental health[edit]

There are a variety of psychiatric effects that may occur as a result of electrical injuries. Behavioral changes can occur as well, even if the path of electrical current did not proceed through the head.[7] Symptoms may include:[7]

• Depression, including feelings of low self-esteem and guilt
• Anxiety spectrum disorders, including posttraumatic stress disorder and fear of electricity
• Moodiness, including a lower threshold for frustration and "losing one's temper"
• Memory loss, decreased attention span, and difficulty learning

Arc-flash hazards[edit]

Main article: Arc flash

OSHA found that up to 80 percent of its electrical injuries involve thermal burns due to arcing faults.[15] The arc flash in an electrical fault produces the same type of light radiation from which electric welders protect themselves using face shields with dark glass, heavy leather gloves, and full-coverage clothing.[16] The heat produced may cause severe burns, especially on unprotected flesh. The arc blast produced by vaporizing metallic components can break bones and damage internal organs. The degree of hazard present at a particular location can be determined by a detailed analysis of the electrical system, and appropriate protection worn if the electrical work must be performed with the electricity on.

Pathophysiology[edit]

The minimum current a human can feel depends on the current type (AC or DC) as well as frequency for AC. A person can sense electrical current as low as 1 mA (rms) for 60 Hz AC and as low as 5 mA for DC. At around 10 mA, DC current passing through the arm of a 68-kilogram (150 lb) human can cause powerful muscle contractions; the victim is unable to voluntarily control muscles and cannot release an electrified object.[17] This is known as the "let go threshold" and is a criterion for shock hazard in electrical regulations.

The current may, if it is high enough and is delivered at sufficient voltage, cause tissue damage or fibrillation which can cause cardiac arrest; more than 30 mA[9] of AC (rms, 60 Hz) or 300–500 mA of DC at high voltage can cause fibrillation.[12][18] A sustained electric shock from AC at 120 V, 60 Hz is an especially dangerous source of ventricular fibrillation because it usually exceeds the let-go threshold, while not delivering enough initial energy to propel the person away from the source. However, the potential seriousness of the shock depends on paths through the body that the currents take.[12] If the voltage is less than 200 V, then the human skin, more precisely the stratum corneum, is the main contributor to the impedance of the body in the case of a macroshock—the passing of current between two contact points on the skin. The characteristics of the skin are non-linear however. If the voltage is above 450–600 V, then dielectric breakdown of the skin occurs.[19] The protection offered by the skin is lowered by perspiration, and this is accelerated if electricity causes muscles to contract above the let-go threshold for a sustained period of time.[12]

If an electrical circuit is established by electrodes introduced in the body, bypassing the skin, then the potential for lethality is much higher if a circuit through the heart is established. This is known as a microshock. Currents of only 10 µA can be sufficient to cause fibrillation in this case with a probability of 0.2%.[20]

Body resistance[edit]

1000 V	700 Ω	1,050 Ω	1,500 Ω

The voltage necessary for electrocution depends on the current through the body and the duration of the current. Ohm's law states that the current drawn depends on the resistance of the body. The resistance of human skin varies from person to person and fluctuates between different times of day. The NIOSH states "Under dry conditions, the resistance offered by the human body may be as high as 100,000 ohms. Wet or broken skin may drop the body's resistance to 1,000 ohms," adding that "high-voltage electrical energy quickly breaks down human skin, reducing the human body's resistance to 500 ohms".[21]

The International Electrotechnical Commission gives the following values for the total body impedance of a hand to hand circuit for dry skin, large contact areas, 50 Hz AC currents (the columns contain the distribution of the impedance in the population percentile; for example at 100 V 50% of the population had an impedance of 1875Ω or less):[22]

Skin[edit]

The voltage-current characteristic of human skin is non-linear and depends on many factors such as intensity, duration, history, and frequency of the electrical stimulus. Sweat gland activity, temperature, and individual variation also influence the voltage-current characteristic of skin. In addition to non-linearity, skin impedance exhibits asymmetric and time varying properties. These properties can be modeled with reasonable accuracy.[23] Resistance measurements made at low voltage using a standard ohmmeter do not accurately represent the impedance of human skin over a significant range of conditions.

For sinusoidal electrical stimulation less than 10 volts, the skin voltage-current characteristic is quasilinear. Over time, electrical characteristics can become non-linear. The time required varies from seconds to minutes, depending on stimulus, electrode placement, and individual characteristics.

Between 10 volts and about 30 volts, skin exhibits non-linear but symmetric electrical characteristics. Above 20 volts, electrical characteristics are both non-linear and symmetric. Skin conductance can increase by several orders of magnitude in milliseconds. This should not be confused with dielectric breakdown, which occurs at hundreds of volts. For these reasons, current flow cannot be accurately calculated by simply applying Ohm's law using a fixed resistance model.

Point of entry[edit]

• Macroshock: Current across intact skin and through the body. Current from arm to arm, or between an arm and a foot, is likely to traverse the heart, therefore it is much more dangerous than current between a leg and the ground. This type of shock by definition must pass into the body through the skin.
• Microshock: Very small current source with a pathway directly connected to the heart tissue. The shock is required to be administered from inside the skin, directly to the heart i.e. a pacemaker lead, or a guide wire, conductive catheter etc. connected to a source of current. This is a largely theoretical hazard as modern devices used in these situations include protections against such currents.

Electrocution[edit]

The earliest usage of the term "electrocution" cited by the Oxford English Dictionary was an 1889 newspaper reference to the method of execution then being considered.[24] Shortly thereafter, in 1892, the term was used in Science to refer generically to death or injury caused by electricity.[24]

Factors in lethality of electric shock[edit]

Log-log graph of the effect of alternating current I of duration T passing from left hand to feet as defined in IEC 60479–1.[25]
AC-1: imperceptible
AC-2: perceptible but no muscle reaction
AC-3: muscle contraction with reversible effects
AC-4: possible irreversible effects
AC-4.1: up to 5% probability of ventricular fibrillation
AC-4.2: 5–50% probability of fibrillation
AC-4.3: over 50% probability of fibrillation

The lethality of an electric shock is dependent on several variables:

• Current. The higher the current, the more likely it is lethal. Since current is proportional to voltage when resistance is fixed (ohm's law), high voltage is an indirect risk for producing higher currents.
• Duration. The longer the duration, the more likely it is lethal—safety switches may limit time of current flow
• Pathway. If current flows through the heart muscle, it is more likely to be lethal.
• High voltage (over about 600 volts). In addition to greater current flow, high voltage may cause dielectric breakdown at the skin, thus lowering skin resistance and allowing further increased current flow.
• Medical implants. Artificial cardiac pacemakers or implantable cardioverter-defibrillators (ICD) are sensitive to very small currents.[26]
• Pre-existing medical condition.[27]
• Age and sex.[28]

Other issues affecting lethality are frequency, which is an issue in causing cardiac arrest or muscular spasms. Very high frequency electric current causes tissue burning, but does not penetrate the body far enough to cause cardiac arrest (see electrosurgery). Also important is the pathway: if the current passes through the chest or head, there is an increased chance of death. From a main circuit or power distribution panel the damage is more likely to be internal, leading to cardiac arrest.[citation needed] Another factor is that cardiac tissue has a chronaxie (response time) of about 3 milliseconds, so electricity at frequencies of higher than about 333 Hz requires more current to cause fibrillation than is required at lower frequencies.

The comparison between the dangers of alternating current at typical power transmission frequences (i.e., 50 or 60 Hz), and direct current has been a subject of debate ever since the war of the currents in the 1880s. Animal experiments conducted during this time suggested that alternating current was about twice as dangerous as direct current per unit of current flow (or per unit of applied voltage).

It is sometimes suggested that human lethality is most common with alternating current at 100–250 volts; however, death has occurred below this range, with supplies as low as 42 volts.[29] Assuming a steady current flow (as opposed to a shock from a capacitor or from static electricity), shocks above 2,700 volts are often fatal, with those above 11,000 volts being usually fatal, though exceptional cases have been noted. According to the Guinness Book of World Records, seventeen-year-old Brian Latasa survived a 230,000 volt shock on the tower of an ultra-high voltage line in Griffith Park, Los Angeles on November 9, 1967.[30] A news report of the event stated that he was "jolted through the air, and landed across the line", and though rescued by firemen, he sustained burns over 40% of his body and was completely paralyzed except for his eyelids.[31] The shock with the highest voltage reported survived was that of Harry F. McGrew, who came in contact with a 340,000 volt transmission line in Huntington Canyon, Utah.[32]

Prevention[edit]

• Grounding the electrical enclosure of high-voltage machinery.
• Use of insulated gloves, insulated boots, mats and tools.
• Protecting electrical circuit with a residual-current device (RCD).

Epidemiology[edit]

There were 550 reported electrocutions in the US in 1993, 2.1 deaths per million inhabitants. At that time, the incidence of electrocutions was decreasing.[33] Electrocutions in the workplace make up the majority of these fatalities. From 1980–1992, an average of 411 workers were killed each year by electrocution.[21] Workplace deaths caused by exposure to electricity in the U.S. increased by nearly 24% between 2015 and 2019, from 134 to 166. However, workplace electrical injuries dropped 23% between 2015 and 2019 from 2,480 to 1,900.[34] In 2019, the top 5 states with the most workplace electrical fatalities were: (1) Texas (608); (2) California (451); (3) Florida (306); (4) New York (273); and (5) Georgia (207).[35]

A recent study conducted by the National Coroners Information System (NCIS) in Australia[36] has revealed 321 closed case fatalities (and at least 39 case fatalities still under coronial investigation) that had been reported to Australian coroners where a person died from electrocution between July 2000 and October 2011.[37]

In Sweden, Denmark, Finland and Norway the number of electric deaths per million inhabitants was 0.6, 0.3, 0.3 and 0.2, respectively, in the years 2007–2011.[38]

People who survive electrical trauma may develop a host of injuries including loss of consciousness, seizures, aphasia, visual disturbances, headaches, tinnitus, paresis, and memory disturbances.[39] Even without visible burns, electric shock survivors may be faced with long-term muscular pain and discomfort, exhaustion, headache, problems with peripheral nerve conduction and sensation, inadequate balance and coordination, among other symptoms. Electrical injury can lead to problems with neurocognitive function, affecting speed of mental processing, attention, concentration, and memory. The high frequency of psychological problems is well established and may be multifactorial.[39] As with any traumatic and life-threatening experience, electrical injury may result in post traumatic psychiatric disorders.[40] There exist several non-profit research institutes that coordinate rehabilitation strategies for electrical injury survivors by connecting them with clinicians that specialize in diagnosis and treatment of various traumas that arise as a result of electrical injury.[41][42]

Deliberate uses[edit]Medical uses[edit]

Electric shock is also used as a medical therapy, under carefully controlled conditions:

• Electroconvulsive therapy or ECT, a psychiatric therapy for mental disorders
• As a surgical tool for cutting or coagulation in electrosurgery. An electrosurgical unit (ESU) uses high currents (e.g. 10 amperes) at high frequency (e.g. 500 kHz) with various schemes of amplitude modulation to cut or coagulate
• As a treatment for fibrillation or irregular heart rhythms: see Defibrillation and Cardioversion
• As a method of pain relief: see Transcutaneous electrical nerve stimulation (TENS)
• As a treatment for excessive sweating with a process called iontophoresis
• Electrodiagnosis, for example nerve conduction studies and electromyography
• Electroporation for gene delivery

Entertainment[edit]

Mild electric shocks are also used for entertainment, especially as a practical joke for example in such devices as a shocking pen or a shocking gum. However devices such as a joy buzzer and most other machines in amusement parks today only use vibration that feels somewhat like an electric shock to someone not expecting it.

It is also used entertainingly for sex stimulation. This is usually done via the use of an erotic electrostimulator which induces erotic electrostimulation. These devices may include a violet wand, transcutaneous electrical nerve stimulation, electrical muscle stimulation, and made-for-play units.

Policing and personal defense[edit]

Electroshock weapons are incapacitant weapons used for subduing a person by administering electric shock to disrupt superficial muscle functions. One type is a conductive energy device (CED), an electroshock gun popularly known by the brand name "Taser", which fires projectiles that administer the shock through a thin, flexible wire. Although they are illegal for personal use in many jurisdictions, Tasers have been marketed to the general public.[44] Other electroshock weapons such as stun guns, stun batons ("cattle prods"), and electroshock belts administer an electric shock by direct contact.

Electric fences are barriers that use electric shocks to deter animals or people from crossing a boundary. The voltage of the shock may have effects ranging from uncomfortable, to painful or even lethal. Most electric fencing is used today for agricultural fencing and other forms of animal control purposes, though it is frequently used to enhance security of restricted areas, and there exist places where lethal voltages are used.

Torture[edit]

Electric shocks are used as a method of torture, since the received voltage and current can be controlled with precision and used to cause pain and fear without always visibly harming the victim's body.

Electrical torture has been used in war and by repressive regimes since the 1930s.[45] The United States Army is known to have used electrical torture during World War II.[46] During the Algerian War electrical torture was used by French military forces.[47] Amnesty International published a statement that Russian military forces in Chechnya tortured local women with electric shocks by attaching wires onto their breasts.[48]

The parrilla (Spanish for 'grill') is a method of torture whereby the victim is strapped to a metal frame and subjected to electric shock.[49] It has been used in a number of contexts in South America. The parrilla was commonly used at Villa Grimaldi, a prison complex maintained by Dirección de Inteligencia Nacional, a part of the Pinochet regime.[50] In the 1970s, during the Dirty War, the parrilla was used in Argentina.[51] Francisco Tenório Júnior (known as Tenorinho), a Brazilian piano player, was subjected to the parrilla during the military dictatorship in Brazil.[52]

Advocates for the mentally ill and some psychiatrists such as Thomas Szasz have asserted that electroconvulsive therapy (ECT) is torture when used without a bona fide medical benefit against recalcitrant or non-responsive patients.[53][54][55]

The Judge Rotenberg Center in Canton, Massachusetts has been condemned for torture by the United Nations special rapporteur on torture for its use of electric shocks as punishment as part of its behavior modification program.[56][57]

Japanese serial killer Futoshi Matsunaga used electric shocks to control his victims.[58]

Capital punishment[edit]

Main article: Electric chair

Electric chair in Sing Sing

Electric shock delivered by an electric chair is sometimes used as an official means of capital punishment in the United States, although its use has become rare from the 1990s onward due to the adoption of lethal injection. Although some original proponents of the electric chair considered it to be a more humane execution method than hanging, shooting, poison gassing, etc., it has now generally been replaced by lethal injections in states that practice capital punishment. Modern reporting has claimed that it sometimes takes several shocks to be lethal, and that the condemned person may actually catch fire before death.

Other than in parts of the United States, only the Philippines reportedly has used this method, from 1926 to 1976. It was intermittently replaced by the firing squad, until the death penalty was abolished in that country. Electrocution remains legal in at least 4 states (Florida, Alabama, North Carolina and Kentucky) of the United States.[when?][59]
