Contractors with brooms are a huge pet peeve of mine at a construction site. Seriously, WTF? You take all the dust and re-suspend as much of it as possible into the air?

Every construction site should have a HEPA-filtered vacuum with a filter bag. (The bagless kind is to be reserved for special cases that need it, and people should wear respirators when emptying it, TYVM.). Brooms are for non-vacuumable debris only, and subcontractors should be reminded of this regularly.

Keeping dust down with water sprayers should be a thing. Also, there should be particulate counters and VOC sensors all around sites to indicate what level of PPE is non-obvious but needed.

    For indoor construction, a water sprayer seems like a mistake. It would turn all that only-mildly-nasty dust into hard-to-remove goo, not to mention making wood soggy and damaging gypsum and other materials.

    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.
