I hope every one also noted the comments about the static electricity
that can build up in plastic pipes in your dust collection system.
They must be grounded to dissipate this charge.

Also while the article is about wood dust, the dust of other organic
material can be equally explosive.

Bottom line keep things clean and avoid excessive dust.


If you notice static from your DC system, by all means ground it. It's not
for safety per se, but just to keep you from getting an annoying shock.
One of the normal human reactions when you get a shock is to move rapidly
away from it, which could cause you to hit something.

OK, ground the equipment (it should be anyway) but the plastic pipe
between them? Really?! The only thing I see the ground wire
accomplishing is to plug the thing up.

I had to ground the discharge chute (a piece of downspout extender) on my
planer because of the annoying shocks. That's the only reason I bothered.
