Read a thing about the dust from joint compound and it got me thinking
I was looking at some safety stuff online and found out that the silica dust from sanding drywall mud can be up to 90% crystalline silica, which is way higher than I thought. This was on a government workplace safety site, and it really made me pause. Do you guys use a specific vacuum or air scrubber on every job, or just for the big sanding days?

That 90% number gets thrown around a lot, but it's for the dust from the compound itself, not the air in the room. In a real house, the dust mixes with everything else. I've seen guys tape plastic and use a box fan in the window for years with no issues. A full vacuum setup is great for new construction, but for a small patch job it feels like overkill.

Totally agree, seen the same thing work fine.

My old boss got us a HEPA vac after a guy got a bad cough. We hook it right to the sander now, even for small stuff. Makes a huge difference with the dust cloud.
