I just about set my house on fire.

I bet you have a gas stove, right? NO OPEN FLAMES WHEN DEALING WITH FLAMABLE VAPORS! EVER! It's like sparking your bowl while sitting in a puddle of gasoline! Even if it wasn't a gas stove, flamable vapors are heavier than air, so your range vent wasn't able to completely remove the iso vapors before they hit ignition temperature (according to the MSDS for isopropyl alcohol, ignition temperature as a vapor in the air is as low as 93c or 200f!)

It was a gas stove, and now I know exactly how it caught on fire. I remember watching the isopropyl fumes sitting on top of the liquid. I was wondering why they were just floating there, and why the exhaust fan wasn't sucking them up. Now I know that the fumes flowed down and caught on fire.

I'm glad your ok, and you posted this, so hopefully no one else has the same experience you did! You might even save a life! (I hope that thought makes you feel a little better )

Thats exactly why I posted this. Remember folks, if you ever make a mistake, tell someone else so they don't make it as well!
