What can be the consequence of failing to observe the arc flash boundary?

Failing to observe the arc flash boundary can lead to potential serious burns or injuries from an arc flash. The arc flash boundary is the distance from exposed live parts within which a person could receive a second-degree burn if an arc flash occurs. This risk is significant because arc flashes can produce extremely high temperatures and explosive forces, resulting in severe injuries or even fatalities.

Understanding the importance of maintaining a safe distance from energized equipment is crucial in the electrical field. This boundary is established based on the energy levels that could be released during a fault and is designed to keep workers safe from those hazards. Therefore, approaching or working within this boundary without appropriate protection, training, or equipment significantly increases the risk of life-altering injuries, highlighting the critical nature of adhering to safety protocols.
