What fire extinguisher did you use? I do not mean to cause unnecessary worry but if it's the powder variety it has borax as an ingredient. Problem with this type is 1. you'll have no problem going to the toilet the next day after inhaling and 2. which is quite a problem, it will corrode all electronic components, like circuitboards and electronic contacts of equipment that is exposed to it.
Let's hope you will not have problems with it!
I threw all powder extinguishers away and bought myself a foam-version which is harmless. The best but also most expensive is probably Co2.
