I didn't appreciate the whole antistatic thing until I started hanging my extractor hose from a boom arm above my bench.
I started getting shocks from the hanging hose when using my track saw, the worst part was I often got the shock from the hose catching my ear which was actually quite painful!
I realised that when I set up the boom arm I had added a 2m length of non anti static hose between the green Festool hose and the Festool extractor, obviously breaking the route to the ground

To overcome this I ran some wire from the end of the Festool hose to where the hose plugs in the vac so bridging the gap where the non antistatic hose is, happy to say I haven't had a shock since.
The Festool vacs have some metal prongs in the socket where you plug the hose in, I've always presumed these are to do with the antistatic feature and earthing the hose , if this is true I guess not just any old vac will work with an antistatic hose unless you earth it some other way.
I did use an antistatic hose with what I presume was a non antistatic extractor for quite a while and didn't get a shock but looking back I do wonder if the hose dragging on the concrete floor was maybe earthing it?
Pretty sure I've only ever had shocks when using the track saw and then do wonder if it's dependent on the material you are cutting?
