contactWebUnderstanding “Arc Flash” Simply put, an arc flash is a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to ground. The results are often violent and when a human is in close proximity to the arc flash, serious injury and even death can occur.
contactWebArc Flash PPE Category Explained Understanding the Arc Flash PPE Category is an essential component of electrical worker safety. Electrical workers must wear and be properly trained in the safe use and application of appropriate personal protective equipment (PPE) for the possible electrical hazard with which they may face.

contactFlash Protection Boundary (outer boundary): The flash boundary is the farthest established boundary from the energy source. If an arc flash occurred, this boundary is where an employee would be exposed to a curable second degree burn (1.2 calories/cm2). The issue here is the heat generated from a flash that results in burns.
