Any thing can be handled WITH THE PROPER SAFETY PRACTICES. It is when
you neglect those practices that accidents happen.

In the winter when doing a lot of work on my table saw, I turn off all
spark producing devices, as dust like volatile liquids can explode
with an ignition source and the right concentration. With saw dust
the chances of explosion are extremely low. But the chances of one
house blowing up from a gas leak are extremely low.

It's been a long time since I've seen the saw dust explosion thing... IIRC,
it takes a dust to air ratio so thick that you can't breath.

And it takes actual dust, not the chips produced by most cutting
tools.

A really big sander might do it but I would be very surprised if
anything found outside of a large factory would.

When I first started WW, I made a plywood disk and glued sandpaper to it
for my Tsaw, trying to make a disk sander. It filled my whole shop with
wood dust. I never used it again, bought a disk sander, dust collection
and so on. It was enough dust powder to make any OSHA hack wring his
hands into fat little government stumps.

My coal furnace converted to gas was in the middle of it all, but no
bang. My main concern was my shop was covered in dust, I had a hard time
breathing, and the Tsaw turned WAY to fast to be a sander.
