Leon,

I agree with your comments. Very good point on the flammables.

One of the books I read suggested it is not worth the chance to use PVC
ducting. I would say it is very safe along with some grounding.

I think the chances are slim but possible depending on the circumstances.
Half of my 20 flexible hose is grounded and I get zapped on occasion. For
that matter I get zapped every time I get out of my truck during the winter
months.
