graphite is not asbestos, a tool shop is not a mine... If you got a lot of graphite (and I guess other) materials in your office from the tool shop next door that means just what I noted, there is poor filtration of the air causing pollution to spread.
By your own (and ADs) logic, offices are a major source of graphite dust because that's where the dust was found.
Of course in reality the graphite was most likely put into the air in the toolshop where it is often used as a lubricant for lathes and other machines.
