Fire on USS Jacksonville

This quick article from the Portsmouth Herald discusses a small fire aboard USS Jacksonville. There's a lot of "hot work" (welding) that goes on during these overhauls; my guess is that heat from a welding job caused a small fire. Each welder is supposed to have a "fire watch" whose only duty is to watch for smoke. However, if they were welding on a deck or bulkhead, I could imagine someone didn't realize that they had to have an additional fire watch on the other side...
