Frequent question: What three factors determining whether electrical shock is fatal?

What are the 3 main factors the determine the severity of an electrical shock?

The severity of electrical shock or electrocution injuries usually depends on three things: (1) the path the current travels in and through the body, (2) the amount of voltage (high-voltage versus low-voltage), and (3) the type of current (alternating current or AC versus direct current or DC).

What determines how dangerous an electric shock is?

The electric current in amperes is the most important physiological varible which determines the severity of an electric shock. However, this current is in turn determined by the driving voltage and the resistance of the path which the current follows through the body.

Which organ is mainly affected by electric shock?

Electric injury can also affect the central nervous system. When a shock occurs, the victim may be dazed or may experience amnesia, seizure or respiratory arrest. Long-term damage to the nerves and the brain will depend on the extent of the injuries and may develop up to several months after the shock.

What is the most common shock related injury?

Electrical burns are the most common shock-related, nonfatal injury. They occur when a worker contacts energized electrical wiring or equipment. Although electrical burns can occur anywhere on the body, they most often occur on the hands and feet.

GOOD TO KNOW:  Why does the solution of calcium chloride conduct electricity?

What are the four effects of electricity?

The ‘effects of electricity’ line

  • magnetic effect.
  • heating effect.
  • chemical effect.
  • electric shocks.

What should you do if someone has had an electric shock?

If someone has had an electric shock, switch off the electrical current at the mains to break the contact between the person and the electrical supply. If you can’t reach the mains supply: Do not go near or touch the person until you’re sure the electrical supply has been switched off.

What are four signs of shock?

Signs and symptoms of shock vary depending on circumstances and may include:

  • Cool, clammy skin.
  • Pale or ashen skin.
  • Bluish tinge to lips or fingernails (or gray in the case of dark complexions)
  • Rapid pulse.
  • Rapid breathing.
  • Nausea or vomiting.
  • Enlarged pupils.
  • Weakness or fatigue.

What is the difference between electrocution and shock?

Many people use electrocution vs shock interchangeably. But the difference between an electrocution and an injury from an electrical shock is literally a matter of life and death. … An electrocution means that a person has died as a result of an electricity.

What is shock hazard?

A shock hazard is the potential electric shock to a person that can be caused by many circumstances. It occurs when there is a voltage difference that a person may come into contact with.
