WHAT IS AN ARC FLASH?
An electric arc occurs whenever a circuit breaker, switch or isolator (Device) is opened and when there is current flowing in the circuit. However, most devices under normal operating conditions are designed to control the arc when opening or closing.
An arc flash may occur when the arc is uncontrolled and there is sufficient energy released to cause harm or damage.
Arc flashes occur both at high voltage and low voltage. There is little discrimination: low voltage arc flashes injuries are just as damaging at high voltage injuries.
Put simply: An Arc Flash is the light and heat produced from an electrical arc supplied with sufficient energy to cause significant damage, fire or injury.
An Arc Flash can cause minor injuries, third-degree burns and potential death as well as other injuries including blindness, hearing loss, nerve damage and cardiac arrest. Fatal burns can occur when the victim is several feet from the arc. Serious burns are common at a distance of 10 feet – arc flash can generate heat 4 times greater than the surface of the sun.
