Lol. That idiot didn't think ahead that that__ type of acid would eat through the bathtub ( made of plastic or fiberglas? ) also. Plus it would continue eating through the floor and wood joists.
Or bring a pumper truck someone has bought from a fire dept. that can spray water through a fire hose nozzle over a hundred feet or so straight up.Bring a ladder truck too just to get more height if necessary.
