What is an arc flash?

An arc flash is a dangerous electrical event that occurs when an electrical fault causes a rapid release of energy through the air, resulting in a bright flash and an explosion-like effect. This phenomenon can produce intense heat, light, and pressure, potentially leading to severe injuries or fatalities for workers in proximity. Arc flashes typically happen in high-voltage environments and can be triggered by equipment failure, human error, or improper maintenance. Proper safety precautions and protective equipment are essential to mitigate the risks associated with arc flashes.
