OSHA classifies it as non-toxic. The MSDS sheet is at the link on the right in PDF format. It’s an alcohol. The only hazard is it is flammable. Drinking it won’t kill you any more than trying to drink Everclear.

I'm pretty sure Everclear has been responsible for many deaths over the years. The way it works is: You put a little Everclear in your glass of kool-aid. You drink it. You make a second glass, but now you can't taste the alcohol, so you pour more Everclear in. By the 3rd or 4th glass, you're up to about a 50/50 mix. I don't remember what happens after that.
