DarthKermit: Apparently silica dust (what you get from cutting concrete) is nearly as bad as asbestos, but our laws have not changed to reflect the dangers of this yet.
While silicosis has been long recognised as an issue from industrial exposure to silica dust, and it's now been classified by IARC as a carcinogen (upgraded from a "suspected" human carcinogen), it's not in the same league as asbestos, asbestosis, and mesothelioma.
Avoiding inhalation of any dust is a good idea.
One which I'm acutely aware of at the moment is sawdust - I'm working (planing, cutting) H3.2 treated framing timber.
People living on unsealed roads are exposed to silica dust. I believe that Golden Bay/Nelson road dust may also contain some asbestos.
