Known the risks
Gain a complete understanding of the risks associated with arc flash hazards. With that understanding, formulate a complete arc flash hazard identification program, designed to mitigate arc flash risks.
Arc Flash Injuries
Arc flash injuries are almost always extremely severe. Intense heat, up to 35k degrees F, can cause fatal burns even when the victim is up to 5 feet away from the source. Serious burns can still occur at up to 10 feet. With such extreme heat, metal can vaporize, causing additional hazards from molten droplets which can be propelled by the force of the flash. Finally, high intensity flashes can cause permanent eye damage resulting in blindness.
Arc flash has only begun to receive significant industry attention in recent years. Before arc flash was understood, it was believed that electrical shock was the primary cause of all injuries in an electrical accident. While electrical shock does cause burns, the majority of all hospital admissions due to electrical accident related injuries were from arc flash. Industry professionals estimate that at least 5 to 10 arc flash explosions occur per day in the U.S., resulting in approximately 1 to 2 deaths daily.
Industry Preparedness
The electric industry is becoming increasingly aware of a phenomenon known as arc flash, a short circuit that passes through air between two live conductors, or between a live conductor and ground. This short circuit can be accompanied by incredible amounts of heat and pressure, and the results are often deadly. The frequency of reported incidents is on the increase, prompting increased awareness and action in the electric and safety industries.
Arc flash can be caused from something as simple as approaching a high amperage source with a conductive object. Poorly maintained equipment or sub-standard parts may also trigger an arc flash. Missing insulation, corrosion or impurities on conductors may also cause arc flash to occur.
