Absolutely. I'd like to see that risk assessment. Not all spray bottles are created equal. They have different size nozzles, spray different size mist particles, some drip, and so on.
Without a clear make/model for the spray bottles and some kind of testing, I wouldn't want that much methanol near a flame in a classroom.

>My faculty like this method because they say that the sprayed mist poses little risk.
Given the high level of social concern around these sorts of demonstrations and it is being held in a public space, I would review their documented risk assessment that supports this statement with the local Authority Having Jurisdiction to get their opinion on this.
