Mell Why are severe electric shocks so dangerous?
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. Still larger currents result in tissue damage and may trigger ventricular fibrillation or cardiac arrest.
Why is getting electrocuted dangerous?
An electrical shock may cause burns, or it may leave no visible mark on the skin. In either case, an electrical current passing through the body can cause internal damage, cardiac arrest or other injury. Under certain circumstances, even a small amount of electricity can be fatal.
Do you that electric shock can cause death Why?
An electric shock may directly cause death in three ways: paralysis of the breathing centre in the brain, paralysis of the heart, or ventricular fibrillation (uncontrolled, extremely rapid twitching of the heart muscle).
What are two ways an electric shock can harm the body?
An electric shock for a lower voltage can result in superficial burns on the surface of the skin. But, electric shocks of voltage between 500 to 1000 volts can give rise to internal burns. It can lead to organ burns that can also affect the heart. This makes the burns; caused from electric shock different from chemical burns and fire burns.
What are electrical shock hazards?
Electrical hazard or Electric Shock may be defined as “Dangerous event or condition due to direct or indirect electrical contact with energized conductor or equipment and from which a person may sustain electrical injury from shock, damage to workplace environment, damage to property or both.
What are the side effects of electric shock?
Some of the more serious and possibly fatal side effects of electrical shock are: Severe burns at point of contact and along the electricity’s course through the body. Vision loss. Hearing loss. Brain damage. Respiratory arrest or failure.
Why is severe electric shock dangerous?
Dangers of Electric Shock The severity of injury from electrical shock depends on the amount of electrical current and the length of time the current passes through the body. A severe shock can cause much more damage to the body than is visible.
