What range of electrical voltage will cause significant harm to the body?

High voltages can also cause severe burns (as seen on pages 9 and 10). At 600 volts, the current through the body may be as great as 4 amps, causing damage to internal organs such as the heart. High voltages also produce burns. In addition, internal blood vessels may clot.

What are side effects of high voltage electrocution?

What are the symptoms of an electric shock?

• loss of consciousness.
• muscle spasms.
• numbness or tingling.
• breathing problems.
• headache.
• problems with vision or hearing.
• burns.
• seizures.

What level of electric shock requires prompt medical attention?

When to see a doctor Not every person who experiences electric shock needs to visit the emergency department (ED). Follow this advice: Call 911 if a person experiences a high voltage shock of 500 V or more. Go to the ED if a person experiences a low-voltage shock resulting in a burn.

What are the three possible effects of electric shock on the human body?

A shock can affect the nervous system When nerves are affected by an electric shock, the consequences include pain, tingling, numbness, weakness or difficulty moving a limb. These effects may clear up with time or be permanent. Electric injury can also affect the central nervous system.

How many amps can most household and industrial lines safely carry?

Most common household circuits are wired for 15 amps or 20 amps. Overcurrent protection devices protect wiring and equipment from overheating and fires. They may – or may not – protect you from electrical shock. If the current isn’t high enough, the fuse won’t blow or the circuit breaker won’t trip.

Can being electrocuted affect your heart?

A shock can cause cardiac arrest If a current of 50 mA passes through the heart, it can cause cardiac arrest. The heart is also a muscle, which beats to pump blood through the body.

What does it feel like to electrocuted?

A minor shock may feel like a tingling sensation which would go away in some time. Or it may cause you to jump away from the source of the current. The sensations might feel like they are piercing every bit of your body. It can feel like you got hit by a train or you might not even remember what happened.
