.... an insurance adjuster who told me one of
the causes of fires in a home are these box fans...

One of 10,000 plus causes! And what was the ranking of box fans on
this list of causes?

If box fans are so deadly, why do "agencies" give them away free, to
those in need, during extra hot weather times?

Maybe one should look at the responsibleness (or is that
irresponsibleness) of the user, rather than blame the box fan.
