What is one of the dangers posed by an arc flash?

One of the primary dangers posed by an arc flash is the risk of severe thermal burns. An arc flash occurs when a high-voltage gap exists, allowing electrical currents to flow through the air, which generates an incredible amount of heat and light. The temperatures reached during an arc flash can exceed 19,000 degrees Fahrenheit, which is sufficient to cause serious burns to anyone in proximity without proper protective equipment. This extreme heat can ignite clothing, damage skin, and lead to significant injury or even fatality. Understanding the severity of thermal burns helps in reinforcing the importance of safety measures and protective gear in environments where electrical hazards may be present.
