Yeah a high charge from the fast moving brushes of a VC on a carpet would qualify there Pete. Them buggers build up a pretty good spark. Especially the ones without a dedicated ground wire attached to the casing going to ground in the outlet.

You might feel different after you read this.

Ive tried setting off BP with one of those electric sparkers they install on gas stoves and couldnt get it to light off. Maybe if its super super fine bp dust, thats normally the most dangerous and blows up their plants, but not so much the courser powder.

alls I can tell you is the vacuum lit it off.if you want to use one , go for it . I will not.
