I'm certified in AB removal. If you don't know what you are talking about, don't post. A professional would do as I stated with one more process. They would provide a sealed staging area to change clothes and clean their shoes (or remove booties) before proceeding to the outside or another part of the house. I should have mentioned not tracking any debris out of the work area rather than thinking that was covered in "common sense."

The sealed transfer area is the same for any project, meaning the same for far more intricate removal such as loose AB over pipes and ducts. There is no half way on that. However, the risk to a homeowner for tile removal and subsequent contamination is minimum concerning floor tiles. I would say there is already AB present in the room and on the outside. Using the HEPA filter on the vac should remediate the situation to safe levels should the level even get to noticeable.

I don't know how old the home is, but AB is present in a lot of construction materials. Anyone could make a mountain out of this molehill. The concrete, the old plaster or drywall, ceiling tiles, etc.

Shoot, if you want, you could make this into a superfund clean-up project.

It's not at this point.
