Styrofoam fumes

[eS]

A styrofoam box for keeping food cold was accidently put on fire in my
kitchen today, and I didn't notice it until it was half gone. Huge flames,
but I was able to put them out with water - made a huge mess, though. I
stood in the kitchen, cleaning up afterwards, and I breathed in as little as
possible of the fumes.

I was wondering about the fumes - should I be concerned, or take any
precautions? There was a distinct smell of, well, burnt styrofoam, but the
kitchen is ventilated and has a window. The smell is still discernible.

Any advice would be appreciated.
