Need some advice ASAP. I sprayed bleach spray (1.5%) on my kitchen floor and wiped it up with some wipes containing ispropyl alcohol (5%). Online states a dangerous release of chemical gases would occur! Would this of happened in this case? Would they keep reacting?

You're OK. In actuality, the bleach was 98.5% water and the isopropanol was 95% water. O2 was liberated and the alcohol and water evaporated. It can be a problem with more concentrated solutions.

Not enough here to be unsafe and a waste of time to clean a floor with to begin with but just ventilate.
