the op said the ozone generator was going to be run UNDER THE HOUSE in
the crawl space, not in the living area

Since crawl spaces are usually pretty drafty you should be able to be back
into the house the next day. In any event, I would/ have opened up every
window in the house for a couple of hours to evacuate the residual gas. If
you have a hot air heating system, turn it on during the treatment in order
to treat the ducts and afterward, during the airing out phase, to distribute
clean air and assist in evacuating the ozone.
