I've seen some shows, maybe not on EMERGENCY!, but maybe on some other show, the a wire shorting out, and POOF! A fire breaks out. How fast can an electrical fire burn through a structure. The fire in my story that I'm writing, well, has nothing to do with the TV show, "EMERGENCY!", but real-life firefighters at Fire Station 12. The fire is caused by two many appliances, plugged into an extension cord that causes an overload, and shorts out. I know liquid can do this, but this is a case of overload.
