I've noticed that a lot in public outdoor construction where I live the last ~10 years. Whenever there's the slightest chance of dust, they have giant water mist spraying machines in addition to the PPE.

may i ask where you live? I’ve worked outdoor construction as a teen for a while, even up till now, I’ve never seen mist sprayers in use round here in Germany.

Western Norway. The rock here is high in quartzite I hear, maybe that's got something to do with it?

Surely you use mist sprayers during building demolition though? That's where I first saw them.

yeah, i think they are pretty standard for demo work around the world afaik. Very interesting, Germany tends to be hellishly strict on building codes and such, but PPE is seriously lacking over here. It bred the mother of all toxic cavalier attitudes.
