Montgomery county sewer cleaning

I’m in Kettering and today crews were on my street all day doing something with the sewers. Had smoke/steam rolling out of them. When I got home after work my house smells like acetone’ish type smell. It’s pretty strong, strong enough I don’t want to be at home. They’ve been done for a couple hours but my house still stinks pretty bad. When I got home I called Kettering first, they told me it’s Montgomery county doing the work, and I called them. The lady was less than helpful and just acted like it’s no big deal, didn’t explain the chemicals used. Anyone know the chemicals they use, and if it’s harmful to be in my house?
