Arc Flash

When working with electrical systems, the risks go far beyond a simple shock. One of the most severe and dangerous events is an arc flash—an explosive release of energy caused by an electrical fault. This is not just a spark; it's a violent event that can produce extreme heat, a blinding flash of light, and a powerful pressure wave. Understanding the mechanics of an arc flash and the steps to prevent one is fundamental to electrical safety.

On a construction site, some dangers are obvious. A high ledge, a deep trench, or a swinging crane load are all visible threats that workers are trained to respect. But one of the most catastrophic hazards is one you can't see until it's too late: an arc flash. This violent electrical explosion can occur in a fraction of a second, releasing a wave of destructive energy with devastating consequences.
