This is interesting: "There is a shift from cooking fatalities to wiring fatalities in more recent years. In the two five-year periods, cooking fatalities went from 31 to 6 (81% drop), compared to wiring fatalities from 13 to 22 (69% increase)" I'd like to see this broken down to copper-aluminum conductor related.

I correct myself. They did break the wiring caused fires down by conductor type and as I suspected aluminum conductor would account for the increase in wiring caused fires. I know there are safe and sure ways to terminate aluminum conductor and proper ways of stripping and handling it but aluminum is only used because of its cost effectiveness and special precautions needed for it are not often taken because they are not felt to be cost effective. Improperly terminated aluminum connections are a fire waiting to happen.
