You asked: What is the dangerous component of a live electrical circuit?

Electrocution. The most obvious risk from electricity is electrocution through contact with a live circuit. This is where an electrical current flows through the body which can result in the heart stopping to work (cardiac arrest).

What should never be used on live circuits?

Do not use metal ladders when working near live electrical circuits. 4. Examine all extension cords and power tools before using. 5.

What are the important elements of electrical safety when working around live circuits?

Personal Protective Equipment Requirements for Arc Flash Protection

Category Energy Level
1 4 cal/cm²
2 8 cal/cm²
3 25 cal/cm²
4 40 cal/cm²

What is the most important element in an electrical circuit?

Note that in an electrical circuit, the source elements are the most significant active elements. An energy source, whether a voltage or current source, is of 2 types – Independent and Dependent sources.

Do not use metal ladders when working near live electrical circuits?

When working with electricity or an electrical circuit or equipment, ladder safety should be observed. There are many different types of ladders, and they are made of different materials. Metal ladders should never be used when dealing with electricity. Always choose a non-conductive ladder made of wood or fiberglass.

What are the dangers of electricity?

Examples of electrical hazard risks include:

  • Electric shock and burns from live wire contact.
  • Fires from faulty wiring.
  • Overloading circuits.
  • Leaving electrical parts exposed.
  • Electrocution or burns from lack of PPE.
  • Explosions and fires from explosive and flammable substances.
  • Contact with overhead power lines.

How can the danger of using electricity be avoided?

Avoid electrical hazards both in your home and elsewhere:

  • Never touch a fallen power line. …
  • Avoid contact with overhead power lines during cleanup and other activities.
  • Do not drive through standing water if downed power lines are in the water.

What are the 3 hazards of electricity?

There are three main types of electrical hazards: electric shock, electrical burns, and arc blasts (the effect of blasts). Understanding the basics of these hazards is critical in enforcing electrical safety in the workplace.

What are the two major hazards of electricity?

There are two known hazards of electricity—thermal and shock. A thermal hazard is one where excessive electric power causes undesired thermal effects, such as starting a fire in the wall of a house. A shock hazard occurs when electric current passes through a person.
