Interesting that "Every one here knows that sawdust ..."
Every year when I taught Shop I'd gather my students out back in the compound and show them what happens when sawdust is puffed up (air through a hose) under a large can with a lighted candle present. I guess it was just magic that blew the can 50' up in the air?

See the winky. Inside joke, I'm guessing. I think he's playin' off another thread about dust collectors.

Yuppers - and notice the lack of a grounding cable/stake.
Wonder if you could bring down one o' them black helicopters with a rig like that?

Sorry, but Leon's right. To prove it, the whole contraption is metal, it's clearly touching the ground, so it's obviously grounded. Therefore it's
*impossible* to ignite anything with it.nice post-production work, it almost looks real.

Dust is dangerous. It is so dangerous, that the government even studies vacuum cleaners!
"This appendix has been prepared to give some guidance on the selection and use of vacuum cleaners for the removal and collection of [dust]. It may also be considered as outline guidance for other low combustibility solids. It ... gives guidance on the features commonly available on domestic, commercial and industrial vacuum cleaners, and the effect that these may have on selection."

This thing would obviously be illegal in California, probably causes cancer in lab rats.

BAH! If you do a Google search on this news group you will find that there are numerous individual posters that have never witnessed this happening or know any one that this has happened to. Therefore it is imposable for it to happen until it does happen to them or some one that they know personally, and then it would only be considered a "freak accident" and freak accidents simply do not happen to some individuals because they know that they are being plenty careful. ;~)

Well said, Leon. All too true.
Anyone that has ever worked, lived, or been around grain silos know for sure that there is no such thing as as dust ignition. Uh - huh.
Besides, when I DAGS Images for "grain silo explosion", it only came back with a few hundred over 16,000 hits. Not nearly enough proof for the fine minds of this venue to prove that fine organic dust can ignite.

yeah - but to be fair, there is a huge difference between a grain silo and a woodworking shop. In the world of grain silos, the potential for an explosion is very expected. It's not a freak accident. There is a lot published on the mixture required for different materials to become explosive, and grain silos can much more easily hit the right mixture for grain. Or at least they used to. I'm sure they are more controlled now.
I'm not an advocate of relying upon freak accident excuses, but I'm equally no advocate of ignoring the probabilities of things either.

I remember reading a story in jr high about the explosive power of grains. There was even some attempts to use them directly in an internal combustion engine. They were trying to perfect a "carburator" for cornstarch. It either did not work well or it worked too well. The resulting explosions destroyed the engine block.

Actually I bet that if there were as many saw dust silos as there are grain silos you might see more explosions.
