Question About Grounding A Dust Collection System

[Hammer5573]

I'm currently adding an addition to my workshop and I'm installing the dust collection lines under the (cement) floor. I'll be using 4" PVC for the lines and making every effort to avoid sharp corners in order to reduce air turbulence. A friend asked me how I intend to ground the collection lines, and I must admit that I never gave that a thought. Does anyone have any suggestions about how I should ground plastic pipe...?

Don't bother.  Grounding dust collection is a safety issue for large, industrial dust management systems like lumber mills, but not for hobbyists.  Plus, grounding is just a way to allow electrons to flow into the ground, and your ducts are going to be literally in the ground!

Here's more detail.

I live in a low humidity area and static charges would build up and zap you now and again. My previous system had a wire wrapped around the duct and was clipped to some foil tape on the ground.  Worked fine.  Current system touches the slab in a few spots and it has not been an issue.  The shop power system has a Ufer ground built in.  You just need to provide the static charge a path to ground that is more desirable than you are and you are already doing that. I would not worry about it.

+1 to @Beechwood Chip When I started woodworking ~30 years ago there was a lot of "advice" about the need to ground dust collection to keep a spark from igniting the dust and causing explosions. It's all been debunked. But the FUD did make me nervous enough to keep me from doing real dust collection for years, so please don't repeat my mistake.

Thanks to all of you for your informed advice...!
