Areview of the literature on the causes of arc flash and other electrical accidents most often points to worker carelessness as the number one problem.
“Carelessness” may be too broad of a generalization. Fatigue or being pushed to quickly restore power by supervisory personnel is not pre-meditated carelessness. In general, too many accident investigations of all sorts often “take the path of least complications” and point the finger and blame at the worker.
