@jerzone I use to service remote tower sites in the summer. Carried my own 14 inch fan. A lot easier to trouble shoot stuff when you don't have sweat running down your face We had a LOT less calls at sites with air conditioning. Just an exhaust fan was a big help.Suspect a lot of the stuff made today for use around offices and such has built in anti-static properties. I've noticed or rather haven't noticed getting zaps while moving about them like years ago. Also think you're correct in that they keep static in mind during design nowadays too
