I had a really gross build up of dirt in the bathroom and figured bleach would take care of it. So I just poured it over the dirty areas around the toilet. (onto tiled flooring)

I didn't mix it with anything but I now I remember how you arent supposed to do that because it can potentially create chlorine gas.

I cleaned up the bleach, opened a window and turned the vent on, then went outside to get fresh air. 

How screwed an I? 

This happened about 1-2 hours back.
