Yup, dust would be a problem! So when we moved our R&D lab to a new area w/concrete floor, the floor was coated with an epoxy-based paint for floors (it was smooth to begin with). Takes care of any dust. After that, standard ESD procedures were used. If static is a real problem in some areas, suggest using anti-stat mats just in those work areas. Roger M.

Currently the plans just call for a concrete floor and we would utilize ESD totes and protected work stations to be in compliance with ANSI S20.20. Can anyone give me some feedback on just having a concrete floor and what "special" handling provisions were needed to be put into place in the absence of a floor grounding method? (This would be without wax, tile, carpet, mats, etc...) Please advise.
