Obvious is a treated concrete floor with an ESD safe coating. The
downside is maintenance and cleaning.
Large ESD mats may be better with dedicated ESD safe work areas.

Brian - Joyce,

This is HEAVY equipment [ie - dirty, filthy, grimy].  I have very little

Any comments on suitability of the bare concrete floor to mitigate
charge
build-up and/or transfer?
