I can’t think of any scenario with dry ice in this situation that would have caused this. You’d have to a significantly elevated level to feel something, at least 2,000 to 5,000 ppm, and the amount of CO2 you can bring into a classroom is what, a couple of pounds? The room would have to be hermetically sealed or you’d have to be huffing the stuff.

I do not have any additional details. Although I do suggest anyone working with hazardous materials with groups (or otherwise) to do a risk assessment and have appropriate controls in place as well as plans for any incidents that could occur.
