What are the 3 basic conditions required for an electric current to flow?

What is an electric current? To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.

What are the 4 main types of electrical injuries?

There are four main types of injuries: electrocution (fatal), electric shock, burns, and falls. These injuries can happen in various ways: Direct contact with exposed energized conductors or circuit parts.

What are the 2 types of circuits?

Series and parallel circuits

• There are two types of circuit we can make, called series and parallel.
• If there are no branches then it’s a series circuit.
• If there are branches it’s a parallel circuit.

What is basic concept of electricity?

The definition of electricity is the flow of charge. Usually our charges will be carried by free-flowing electrons. Negatively-charged electrons are loosely held to atoms of conductive materials. With a little push we can free electrons from atoms and get them to flow in a generally uniform direction.

What are the 5 types of electrical incidents?

That being said, there are six main types of electrical burns: arc burns, low voltage burns, high voltage burns, oral burns, flash burns, and flame burns.

What is standard electrical safety?

Electrical safety standards. Electrical safety is a system of organizational measures and technical means to prevent harmful and dangerous effects on workers from electric current, electric arc, electromagnetic field and static electricity.

What is the most important rule of Electrical Safety?

Avoid water at all times when working with electricity. Never touch or try repairing any electrical equipment or circuits with wet hands.

Is NFPA 70E the law?

The short answer is no, because NFPA 70E© is a consensus standard and not an OSHA regulation which is enforced by federal law. However, OSHA has several requirements that are enforceable by law and the NFPA 70E© is accepted by OSHA as a nationally recognized consensus standard for best practice in the United States.

What are electrical safety guidelines?

Electrical Safety Guidelines. Follow these guidelines for general electrical safety: Be familiar with the electrical hazards associated with your workplace. Unplug electrical equipment before repairing or servicing it. If a prong breaks off inside an outlet, do not attempt to remove it yourself. Call the Facilities Department for assistance.
