Arc Flash

Last updated: March 26, 2024

What Does Arc Flash Mean?

An arc flash is a burst of intense light and heat that happens when current jumps between two electrical conductors.

Arc flashes are quick and sudden and can appear similar to an explosion. They are highly dangerous and have the potential to cause severe burns or loss of life.

The heat generated by an arc flash is incredibly high – greater than the temperature of the surface of the sun. Although it only happens momentarily, it can burn people nearby, melt materials, and ignite flammable materials.

Safeopedia Explains Arc Flash

NFPA 70e is the most widely used standard for arc flash labeling.

These guidelines require all potential arc flash equipment to have a recording of its nominal system voltage, an established arc flash boundary, and PPE suitable for working within that boundary.
