when saw dust ignites and becomes charcoal!!!
in your new house. it took me twenty minutes to find the sander, which hadn’t been used in an hour. check outside for forest fire. no–inside. finally turned of ceiling fan since I had wired it. as soon as I did, flames and smoke emanated from dust catcher on belt sander. weird and amen I smelled it and finally found. needless to say I ran out of house with flaming sander in hand. the sawdust seems now to be literally charcoal.
