I wondered whether you ever experienced a problem with static buildup
on the vacuum hose?

No. There's just not enough grunt in a domestic vacuum. Black hoses
help too - most are static dissipative (if not officially so), just
because carbon black is still a favoured pigment. I've observed
dust-cling, but never even got a tingle from it.

There is _no_ recorded instance of static discharge causing a dust
explosion or fire with wood dust, shavings or wood flour in
woodworking dust collection equipment. There is a robust theoretical
risk-assessment as to why this is impossible.

Sucking up toluene is, of course, another story. Same for cigarette
butts, grinding sparks, and finishing rags.
