What earth shattering news! Haven't electrical fires been started by
virtually everything electrical at one time or another? Just plugging
in too many extension cords into a multi outlet has started them. So
have TV's, lights, outlets, etc. So, why should we be surprised that a
multi-outlet surge protector might not start a fire on a rare occasion
too?
