I'm sorry, but the msdn safety charts say otherwise. It has a health rating of 1, which pretty much means its harmless (it can irritate your skin, but that is about it). Further more, it states that it may be toxic. They don't know if it is. Seeing that this stuf is sold as nail polish remover, i doubt that it's that dangerous.
It is smart using this stuff in well ventilated area and safety glasses are should always be used when working with any kind of chemicals.
