Arc Flash 101
OSHA describes arc flash as “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.” I had never experienced what an arc flash incident looked like until I attended EI’s NFPA (National Fire Protection Association) 70E training course and saw a video example of this phenomenon.
