What is Arc Flash?

Arc Flash is a term used in electrical construction to refer to the release of energy caused by an electric arc. It is a dangerous event that occurs when an electric current passes through an air gap between two electrically-conductive surfaces, and can be caused by a variety of factors such as broken or frayed wires, overloaded circuits, or even dust. Arc Flash is essentially an explosion of energy.

Arc Flash can be incredibly dangerous, and can cause serious injuries and even death. The National Fire Protection Association (NFPA) estimates that there are over 2,000 arc flash incidents per year in the United States, resulting in an average of eight deaths and more than 50 serious injuries. The severity of the incident depends on the amount of energy released and the distance from the source of the arc.

Due to the potential danger of Arc Flash, it is important for electricians to take the necessary safety precautions. This includes wearing the appropriate safety gear, such as flame-resistant clothing and face shields, and using correctly rated circuit breakers and fuses. It is also important to maintain and inspect electrical equipment regularly to reduce the risk of arc flash.

The Origin of the Term 'Arc Flash'

The term 'Arc Flash' was first used in the late 1970s in North America to describe the potential danger of an electric arc. An arc flash is an extremely bright flash of light accompanied by a loud noise, intense heat, and a blast of air, that occurs when an electric current passes through air between two conductors.

The term was first used by electrical engineers and safety professionals to describe the potential danger of an electrical arc. The term was then adopted by the National Fire Protection Association (NFPA) in their NFPA 70E Standard for Electrical Safety in the Workplace, which was first published in 1979.

Since then, the term 'Arc Flash' has become widely used in the electrical industry to describe the potential danger of an electrical arc. It is now used to refer to the protective clothing and equipment workers must wear to protect them from potential arc flash hazards.
