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.
