This type of arc is not even talked about in the literature. Dr. David Sweeting of Australia and I have been working in our papers to bring it to light. iIgnited clothing causes MOST of the injuries in arc flash. One DuPont internal study indicated it contributes to 80% of the injuries in electrical incidents. This was not an electrical worker but the story enlightens us to be sure we use flame resistant, arc rated clothing. It makes a huge difference.
