There will be *much* dust at this point. It will get all round the house.
Have a good hoover ready.
I have an old extractor fan mounted in a large piece of ply for handling
just this. Whenever I'm doing anything majorly dusty, I wedge it into an
open window of the room and shut the doors. The negative pressure this
creates means that the dust does not get anywhere else in the house. It
really does work - I sanded an entire floor once, and not a spot of dust
got into any of the other rooms.
