What do the experts have to say on this?


To date none of the experts have come up with a single
itty-bitty bit of evidence that PVC piping will lead to a
dust collector explosion.

That's the facts, the whole facts and nothing but the facts.

UA100, stopping at the Lancome' counter after suiting up to
go fly with Grandma, over the Sinai of course...

Interesting. So.....

In the book Woodshop Dust Control, Sandor
Nagisygnskfiwef(something-or-other) recommends that the reader NOT use
plastic pipe for the DC system, and shows a lot of detail on grounding
plastic pipe to prevent an explosion. He seems to consider it a real risk.

Yet the concensus here is that it's not a risk in a small-shop environment.
(also other threads have pointed to some good sources of info on why an
explosion is unlikely).

In that book, he also recommends that a DC not be located near a furnace or
water heater - appliances with a pilot light. Is he being overly cautious
in this warning, too? As long as the DC has decent bags so it's not blowing
dust right through, how likely is it that there would be a high enough
concentration of dust to be ignited from a pilot light?

I could be that Sandor Nagyszalanczy is referring to a commercial wood shop and
avoiding a law suit.. The book is not just written for the hobbyist.
