BULL****!

(here we go again!) :-)

It not BS, it could happen but it is not very likely, obtaining the
perfect mixture of very fine dust, oxiding agent and spark is all you
need but odds are not at all good that you acheive that bit of
perfection. Now it you mix in dry coffee creamer rather than sawdust
your chances of an explosion are much better. So do not vacum up a big
spill of coffee creamer with your dust collector if your hoses are not
grounded.

Ten thousand times more likely is that you spill some paint thinner and
drop a lit match on it.

The likelihood of an explosion from a DC is as likely as an explosion by
vacuuming the carpet in your home.

It is a moot point to fear an explosion from a dust collector sucking up
saw dust. There are hundreds of other things in the shop that are more
likely to cause harm.
