This is NOT urban legend. We see sparks and grain dust explosions
every year. It's not a big stretch to imagine a fire from sawdust.
People in this newsgroup have ignited it with sparks or hot metal
particles.

if you have evidence of a static electricity induced explosion in a
home shop dust collection system, post it here. you'll make history-
it will be the first and only time such evidence has come to light.

wanna be famous? go for it....
