SA's use of hyperbole is rubbing off on me.

At my previous job, I would on occasion pull a perforated tile up from the floor of the fab to crawl underneath to locate a network jack. Presumably this is where weeks/months/years of dust would accumulate, and I crawled in a white bunny suit. I'd find dropped pens, fasteners, and paper clips, but upon exiting the subfloor I appeared just as clean as when I entered.
That was another nice thing about servicing PCs located in a clean room; there was no dust to contend with.
It amazed me how much silicon dust could accumulate in PCs located in the rock crushing rooms and not affect operation.
